Human rights defenders have historically been defined on the basis of their actions as defenders. However, as Marxist-feminist scholar Silvia Federici contends, women are inherently politicised and, moreover, face obstacles to political action which are invisible to and untouchable by the law. Labour rights set an example of handling such a disadvantaged political position by placing vital importance on workers’ right to association and collective action. The paper closes with the suggestion that transposing this construction of rights to women would better protect women as human rights defenders while emphasising their capacity for self-determination in their political actions. N2 - Dieses Papier bewertet die Konstruktion der Rechte von Menschenrechtsverteidigern innerhalb des Völkerrechts und ihre Mängel beim Schutz von Frauen. Menschenrechtsverteidiger wurden in der Vergangenheit auf der Grundlage ihrer Tätigkeit als Verteidiger definiert. Wie die marxistisch-feministische Wissenschaftlerin Silvia Federici behauptet, sind Frauen jedoch von Natur aus politisiert und sehen sich darüber hinaus Hindernissen für politisches Handeln gegenüber, die für das Gesetz unsichtbar und unantastbar sind. Die Arbeitsrechte sind ein Beispiel für den Umgang mit einer derart benachteiligten politischen Position, indem sie dem Recht der Arbeitnehmer auf Vereinigungsfreiheit und kollektive Aktionen entscheidende Bedeutung beimessen. Das Papier schließt mit dem Vorschlag, dass die Übertragung dieser Rechtskonstruktion auf Frauen Frauen als Menschenrechtsverteidigerinnen besser schützen und gleichzeitig ihre Fähigkeit zur Selbstbestimmung in ihrem politischen Handeln betonen würde.

We design and implement a randomized field experiment in a large mandatory economics course with blended learning elements. The low-cost treatment induces students to use the online learning system more often, more intensively, and to begin earlier with exam preparation. Treated students perform better in the course than the control group: they are 18.8% (0.20 SD) more likely to pass the exam and earn 6.7% (0.19 SD) more points on the exam. There is no evidence that treated students spend significantly more time, rather they tend to shift to more productive learning methods. The heterogeneity analysis suggests that higher treatment effects are associated with higher levels of behavioral bias but also with poor early course behavior.

We investigate how formal institutions, like product- and labor-market regulations, as well as the quality of regional governments that implement these regulations, affect HGF development across European regions. Using data from Eurostat, OECD, WEF, and Gothenburg University, we show that both regulatory stringency and the quality of the regional government influence the regional shares of HGFs. More importantly, we find that the effect of labor- and product-market regulations ultimately depends on the quality of regional governments: in regions with high quality of government, the share of HGFs is neither affected by the level of product market regulation, nor by more or less flexibility in hiring and firing practices. Our findings contribute to the debate on the effects of regulations by showing that regulations are not, per se, “good, bad, and ugly”, rather their impact depends on the efficiency of regional governments. Our paper offers important building blocks to develop tailored policy measures that may influence the development of HGFs in a region.

We analyze the trade and welfare effects of international trade between these two countries. The welfare analysis indicates that in this framework the large country benefits from free trade and the small country may be hurt by opening to trade. This finding is contrary to the results of Shachmurove and Spiegel (1995) as well as Tharakan and Thisse (2002), who use related models to analyze size effects in international trade, where the small country usually gains from trade and the large country may lose.

We find that the stability of the cartel depends on the relative market size of each firm. Collusion is not attractive for firms with a small home market, but the incentive for collusion increases when the firm’s home market is getting larger relative to the home market of the competitor. The highest stability of a cartel and additionally the highest social welfare is found when regions are symmetric. Further we can show that a monetary transfer can stabilize the market sharing agreement.

This approach yields a critical discount factor that makes different predictions for cooperation than the usually considered sub-game perfect or risk dominance critical discount factors. In laboratory experiments, we find that our factor is useful for predicting cooperation. For payoff changes where the usually considered factors and our factor make different predictions, the observed cooperation is consistent with the predictions based on our factor.

This paper provides experimental evidence on the question whether such sanctioning meets the economic target, i.e., whether evidence of a collusive meeting of the firms and of the content of their communication reliably predicts subsequent prices. We find that already the mere mutual agreement to meet predicts a strong increase in prices. Conversely, express distancing from communication completely nullifies its otherwise price-increasing effect. Using machine learning, we show that communication only increases prices if it is very explicit about how the cartel plans to behave.

We extend these studies through a design that distinguishes between innocuous communication and communication about a cartel, sanctioning only the latter. To this aim, we introduce a participant in the role of the competition authority, who is properly incentivized to judge communication content and price setting behavior of the firms. Using this novel design, we revisit the question whether a leniency rule successfully destabilizes cartels. In contrast to existing experimental studies, we find that a leniency rule does not affect cartelization. We discuss potential explanations for this contrasting result.

We contribute to understanding the inner workings of cartels by studying experimentally the effect of sanctioning institutions on firms’ communication. Using machine learning to organize the chat communication into topics, we find that firms are significantly less likely to communicate explicitly about price fixing when sanctioning institutions are present. At the same time, average prices are lower when communication is less explicit. A mediation analysis suggests that sanctions are effective in hindering cartel formation not only because they introduce a risk of being fined but also by reducing the prevalence of explicit price communication.

Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude tacitly. We document that firms are less likely to communicate explicitly about price fixing and more likely to use indirect messages when sanctioning institutions are present. This effect of sanctions on communication reinforces the direct cartel-deterring effect of sanctions as collusion is more difficult to reach and sustain without an explicit agreement. Indirect messages have no, or even a negative, effect on prices.

Wie andere Universitätsschulen soll sich auch diese Schule durch eine enge und institutionalisierte Beziehung zwischen Schule und Universität auszeichnen, die den ständigen Wissenstransfer zwischen Schulpraxis, Wissenschaft, Lehrkräftebildung und Schulverwaltung unterstützt. Das Rahmenkonzept legt die Grundlagen für eine inklusive Schule, deren Schüler:innen einen Querschnitt der Gesellschaft abbilden, und die in ungleichheitssensiblen Bildungsangeboten alle Bildungsabschlüsse des Landes Brandenburg anbietet. Die Universitätsschule soll den starken Segregationsprozessen in Potsdam entgegenwirken. Im Leitbild werden die Grundwerte (Nachhaltigkeit, Inklusion und Bildungsgerechtigkeit, Menschenrechte und Demokratie, Gemeinschaft, Ganzheitlichkeit) und die Bildungsziele (Transferfähigkeit, kritisch-reflexives Denken und lebensbegleitendes Lernen, Diversitätsbewusstsein und Transkulturalität, Selbstkompetenz und Beziehungskompetenz, Kulturtechniken und digitale Kompetenz) der Universitätsschule dargestellt. Das Pädagogische Konzept veranschaulicht, wie Werte und Bildungsziele in den Bereichen Schulform, Schulkultur, Lernkultur sowie Lernorte und Lernumgebung ausgestaltet werden können. Schließlich wird die Universitätsschule als lernende und lehrende Institution beschrieben, die ein Ort des Transfers von Bildungsinnovationen ist. Dafür soll eine Transferwerkstatt in der Schule verankert werden, die den Wissensaustausch der schulrelevanten Akteur:innen unterstützt und gestaltet.

Both elements of CIL – practice and opinio juris – have assumed novel and broader forms, as noted in the Reports of the Special Rapporteur of the International Law Commission (2013, 2014, 2015, 2016). This paper discusses these Reports and the draft conclusions, and reaction by States in the Sixth Committee of the United Nations General Assembly (UNGA), highlighting the areas of consensus and contestation. This ties to the analysis of the main doctrinal positions, with special attention being given to the two elements of CIL, and the role of the UNGA resolutions. The underlying motivation is to assess the real or perceived crisis of CIL, and the author develops the broader argument maintaining that in order to retain unity within international law, the internal limits of CIL must be carefully asserted.

This paper shows, through analysis of intergovernmental instruments, statements made by representatives of States, and negotiation records, that the rule of law at the United Nations has become increasingly contested in the past years. More precisely, the argument builds on the process of integrating the notion of the rule of law into the Sustainable Development Goals, adopted in September 2015 in the document Transforming our world: the 2030 Agenda for Sustainable Development. The main sections set out the background of the rule of law debate at the UN, the elements of the rule of law at the goal- and target-levels in the 2030 Agenda – especially in the SDG 16 –, and evaluate whether the rule of law in this context may be viewed as a normative and universal foundation of international law. The paper concludes, with reflections drawn from the process leading up to the 2030 Agenda and the final outcome document that the rule of law – or at least strong and precise formulations of the concept – may be in decline in institutional and normative settings. This can be perceived as symptomatic of a broader crisis of the international legal order.

We find that knowledge intensive services benefit from innovation activities in the sense that these activities causally increase their labor productivity. Moreover, the firm size advantage found for manufacturing in previous studies nearly disappears for knowledge intensive services.

It will be argued that important lessons can be learned from the League of Nations’ (LON) efforts in the interwar period and the UN’s activities in the immediate post-WWII era, while taking into account the new challenges that arise from modern communication technology. Taking up the LON’s and UN’s distinction between false and distorted news, the international legal framework will be tested, in particular, against the coverage of the 2016 ‘Lisa case’ by Russian Government-funded media. This coverage is widely considered to be fake news aimed at destabilizing Germany’s society and institutions. The article argues that false news can be subject to repressive regulation in a sensible manner. Distorted news, however, will have to be tolerated legally, since prohibitions in this regard would be too prone to abuse. A free and pluralist media, complemented by an appropriate governmental information policy, remains the best answer to fake news in all its forms. Due diligence obligations to fact-check, transparency, and remedies that are effective despite difficulties in attribution, and despite a lack of universal acceptance, could likewise be conducive.

We study how persistent telework may change energy and transport consumption and costs in Germany to assess the distributional and environmental implications when working from home will stick. Based on data from the German Microcensus and available classifications of working-from-home feasibility for different occupations, we calculate the change in energy consumption and travel to work when 15% of employees work full time from home. Our findings suggest that telework translates into an annual increase in heating energy expenditure of 110 euros per worker and a decrease in transport expenditure of 840 euros per worker. All income groups would gain from telework but high-income workers gain twice as much as low-income workers. The value of time saving is between 1.3 and 6 times greater than the savings from reduced travel costs and almost 9 times higher for high-income workers than low-income workers. The direct effects on CO₂ emissions due to reduced car commuting amount to 4.5 millions tons of CO₂, representing around 3 percent of carbon emissions in the transport sector.

In this paper, we discuss their usefulness and success by analysing the challenges present-ed during NAP processes as well as the benefits this set of actions entails: The challenges for their implementation outweigh its actual benefits. Nevertheless, NAPs have great potential. Based on new research, we elaborate a set of recom-mendations for improving the design and imple-mentation of national action planning. In order to effectively bring NAP into practice, we consider it crucial to plan and analyse every state local circumstances in detail. The latter is important, since the implementation of a concrete set of actions is intended to directly transform and improve the local living conditions of the people. In a long-term perspective, we defend the benefit of NAP’s implementation for complying obliga-tions set up by HR treaties.

Dennoch haben NAPs ein großes Poten-zial. Beruhend auf neueren Forschungen erarbei-ten wir eine Reihe von Empfehlungen zur Ver-besserung der Gestaltung und Umsetzung der nationalen Aktionsplanung. Um einen NAP effek-tiv in die Praxis umzusetzen, halten wir es für entscheidend, die lokalen Gegebenheiten jedes Staates im Detail zu planen und zu analysieren. Letzteres ist wichtig, da die Umsetzung eines konkreten Maßnahmenpakets die Lebensbedin-gungen der Menschen vor Ort direkt verändern und verbessern soll. Langfristig gesehen vertei-digen wir den Nutzen der Umsetzung des NAP für die Einhaltung der in den Menschenrechts-verträgen festgelegten Verpflichtungen.

T2 - KFG Working Paper Series N2 - While some pronouncements of expert treaty bodies have been considered ‘key catalysts’ for the development of international human rights law, others are only selectively referred to in legal practice. This article argues that the varying normative impact is due to the informal character of pronouncements. In the absence of treaty provisions specifying their legal effect, practitioners tend to rely on different factors and arguments when either drawing on or rejecting certain pronouncements. Scholars in turn face difficulties when trying to identify explanatory patterns within this diverging practice as the informal character confronts both international lawyers and international relations scholars with their respective methodological ‘blind spots’. In light of these intradisciplinary challenges, this article explores the extent as to which an interdisciplinary approach helps to assess the reasons for the varying impact of pronouncements. After analysing the factors determining their legal significance on the basis of State practice and the academic debate, this article identifies the drafting process as a factor which promises to be particularly insightful when explored from an interdisciplinary perspective and sketches out a framework for future research.

While the negative effect on the likelihood of living in poverty and the positive effect on the probability of being employed are very robust across the different specifications, the headline estimate-the effect on earnings-is more sensitive to the exclusion of certain regions and survey years.

T1 - Revisiting public investment BT - consumption equivalent public capital and the social discount rate N2 - The consumption equivalence method is the theoretical basis of public cost-benefit analysis. Consumption equivalence public capital prices are explicitly introduces in order to sufficiently care for the opportunity cost of public expenditure. This can solve the dispute about the social rate of discount within public cost-benefit analysis witch was generated on a criterion looking similar to the capital value formula, known as Lind’s approach. The social rate of discount is liberated from opportunity costs considerations and the discounting away of the effects for future welfare vanishes. The corresponding question whether one should accept a positive value of the pure rate of social time preference is an old issue. Its current state between the prescriptive and descriptive view can also be interpreted as a consequence of the oversimplification of standard cost– benefit analysis. But apart from an economic self-process the pure rate of social time preference is also defined as a business-as-usual value of social distance discounting. Hence, a political choice has to be made about this rate which is free in principal.

The main result is the classification of social choice situations which include three types of social choice problems. First, we usually observe the common incompleteness of the Pareto relation. Second, a kind of non-compactness problem of a choice set of social states can be generated. Finally, both can be combined. The first problem root can be regarded as natural everyday dilemma of social choice theory whereas the second may probably be much more due to modeling technique implications. The distinction is enabled at a very general set theoretical level. Hence, the derived classification of social choice situations is applicable on almost every relevant economic model.

N2 - Against the background of the internationally growing number of relapses into conflict, especially following civil wars which have already officially been declared as terminated and the increasing relevance of peacebuilding actions of the international community resulting therefrom, this paper examines the work of the Peacebuilding Commission (PBC) of the United Nations. On the one hand, subsequent to some introductory remarks on the concept of peacebuilding itself as well as on the composition and operating modes of the PBC, its particular mandates are identified systematically while inserting them into the larger context of the peacebuilding system of the United Nations and making an assessment of their fulfilment so far. Thereafter, a description of the future opportunities of the Commission in the field of peacebuilding is given in special consideration of its potential within the system of the United Nations and the respective aspects of international law.

Taking Article 38(1)(d) of the ICJ Statute as a point of departure, he determines through meticolous analysis what ranks as judicial decisions as well as teachings within the meaning of the norm. The author then proceeds to a number of factors to determine authoritativeness: objectivity, knowledgeability, depth of analysis, and the presence or otherwise of reasoning and, in particular, the persuasiveness of an opinion. In the case of judicial pronouncements, the author points out that the paradox between Article 59 and Article 38(1)(d) of the ICJ Statute is only an apparent one. While judgments of the Court are binding only between the parties, it is merely the underlying reasoning that can be taken into account in the context of Article 38(1)(d) if considered persuasive. Without central authority, authoritativenes in international law must always be earned which is also the reason for the lack of an hierarchical order between as well as within judicial pronouncements and learned writings though the former are usually more likely to fulfil the criteria of authoritativeness. In both cases, however, previously acquired reputation of a court or even an individual judge as well as of a learned writer can create a presumption of authoritativeness. On a more general level, the author concludes with a call for a more careful differentiation between the determination of law and its application. Putting the issue discussed into perspective, the author argues that situations of law determination arise, contrary to common understanding, in fact far less often than situations of law application.

Market-based climate policy instruments (e.g., emissions pricing) create incentives to reduce energy consumption by increasing the user cost of fossil energy. This raises the question of whether climate policy should respond to fluctuations in fossil energy prices? We study this question within an environmental dynamic stochastic general equilibrium (E-DSGE) model calibrated on the German economy. Our results indicate that the welfare implications of dynamic emissions pricing crucially depend on how the revenues are used. When revenues are fully absorbed, a reduction in emissions prices stabilizes the economy in response to energy price shocks. However, when revenues are at least partially recycled, a stable emissions price improves overall welfare. This result is robust to different modeling assumptions.

Financially constrained poorer households, who spend a larger relative share of their income on energy, are particularly affected. In this analysis, we examine the macroeconomic and welfare effects of energy price shocks in the presence of credit-constrained households that have subsistence-level energy demand. Within a Dynamic Stochastic General Equilibrium (DSGE) model calibrated for the German economy, we compare the performance of different policy measures (transfers and energy subsidies) and different financing schemes (income tax vs. debt). Our results show that credit-constrained households prefer debt over tax financing regardless of the compensation measure due to their difficulty to smooth consumption. On the contrary, rich households tend to prefer tax-financed measures as they increase the labor supply of poor households. From an aggregate perspective, tax-financed measures targeting firms effectively cushion aggregate output losses.

Our paper attempts to trace these differences in the labor market performance back to the regions' specialization in products that are more or less advanced in their product cycle. The model we develop shows how individual profit and utility maximization endogenously yields higher employment levels in the beginning. In later phases, however, employment decreases in the presence of process innovation. Our model suggests that the only way to escape from this vicious circle is to specialize in products that are at the beginning of their "economic life". The model is based on an interaction of demand and supply side forces.

T2 - CEPA Discussion Papers N2 - The self-employed faced strong income losses during the Covid-19 pandemic. Many governments introduced programs to financially support the self-employed during the pandemic, including Germany. The German Ministry for Economic Affairs announced a €50bn emergency-aid program in March 2020, offering one-off lump-sum payments of up to €15,000 to those facing substantial revenue declines. By reassuring the self- employed that the government ‘would not let them down’ during the crisis, the program had also the important aim of motivating the self-employed to get through the crisis. We investigate whether the program affected the confidence of the self-employed to survive the crisis using real-time online-survey data comprising more than 20,000 observations. We employ propensity score matching, making use of a rich set of variables that influence the subjective survival probability as main outcome measure. We observe that this program had significant effects, with the subjective survival probability of the self- employed being moderately increased. We reveal important effect heterogeneities with respect to education, industries, and speed of payment. Notably, positive effects only occur among those self-employed whose application was processed quickly. This suggests stress-induced waiting costs due to the uncertainty associated with the administrative processing and the overall pandemic situation. Our findings have policy implications for the design of support programs, while also contributing to the literature on the instruments and effects of entrepreneurship policy interventions in crisis situations.

We calibrate the model to key features of Berlin’s housing market, in particular the recent gentrification of inner city locations. As expected, gentrification benefits rich homeowners, while poor renter households lose. Our counterfactual analysis mimicks the rent control policy. We find that this policy reduces welfare for rich and poor households and in fact, the percentage change in welfare is largest for the poorest households. We also study alternative affordable housing policies such as subsidies and re-zoning policies, which are better suited to address the adverse consequences of gentrification.

We use a quantitative equilibrium model with choice of housing, energy use, residential location, transport mode, and energy technology. Pollution comes from commuting and residential energy use. The model parameters are calibrated to replicate key variables for two developing country cities, Maputo, Mozambique, and Yogyakarta, Indonesia. In the counterfactual simulations, we study how various transport and energy policies affect equilibrium pollution. Policies may be induce rebound effects from increasing residential energy use or switching to high emission modes or locations. In general, these rebound effects tend to be largest for subsidies to public transport or modern residential energy technology.

We show that decentralized taxation results in inefficiently high tax rates, whereas centralized taxation yields a common optimal tax rate, and tax rates in the rent-seeking regime can be either inefficiently high or low. We quantify the effects of switching from the observed tax system to the three regimes for Japan and Germany. The decentralized or rent-seeking regime best describes the Japanese tax system, whereas the centralized regime does so for Germany. We also quantify the welfare effects of regime changes.

We find that density significantly increases pollution exposure. Looking only at urban areas, we find that population size affects exposure more than density. Moreover, the effect is driven mostly by population commuting to core cities rather than the core city population itself. We analyse heterogeneity by geography and income levels. By and large, the influence of population on pollution is greatest in Asia and middle-income countries. A counterfactual simulation shows that PM2.5 exposure would fall by up to 36% and NO2 exposure up to 53% if within countries population size were equalized across all cities.

However, Germany has been a respected and highly relevant member of the United Nations not only during its terms on the Security Council but also in “normal” times. The present article attempts to shed light on a few aspects of Germany’s role in the UN during Merkel’s chancellorship with an emphasis on her third term (2014-2017), such as the cooperative relationship between Germany and the UN Secretary-General in important policy fields, Germany’s financial contributions to the UN, the impact of Germany’s EU membership on its UN membership and the country’s efforts with regard to the reform of the Security Council. The paper further provides context for Germany’s abstention in the vote on Security Council Resolution 1973 on Libya in 2011. It concludes by ascertaining that Germany with its approach of active multilateralism has taken its place as one of the leading nations in Europe and is ready to take on responsibility with its partners to achieve a peaceful and stable world order.

This article questions their position. A vertical innovation model with a portfolio of technologies for abatement, adaptation, and general (Harrod-neutral) technology reveals that environmental damage spillovers have a comparable effect on research profits as technology spillovers so that the social costs of depleting public natural capital are internalized. As long as there is free access to information and technology, growth is sustainable and the allocation of research efforts among alternative technologies is socially optimal. While there still is a need to address externalities from monopolistic research markets, no environmental policy is necessary. These results suggest that environmental externalities may originate in restricted access to information and technology, demonstrating that (i) information has a similar effect as an environmental tax and (ii) knowledge and technology transfers have an impact comparable to that of subsidies for research in green technology.

Such schemes promise buyers a reduced price for all units that are bought in a certain time frame if the total quantity that is purchased passes a given threshold. This study finds a loyalty-enhancing effect of retroactive price-reduction schemes only if the buyers ex-ante expected that entering into the scheme would maximize their monetary gain, but later learn that they should leave the scheme. Furthermore, the effect crucially hinges on the framing of the price reduction.

Our paper develops a new method for measuring strategic-uncertainty attitudes and distinguishing them from risk and ambiguity attitudes. We vary the source of uncertainty (whether strategic or not) across conditions in a ceteris paribus manner. We elicit certainty equivalents of participating in two strategic 2x2 games (a stag-hunt and a market-entry game) as well as certainty equivalents of related lotteries that yield the same possible payoffs with exogenously given probabilities (risk) and lotteries with unknown probabilities (ambiguity). We provide a structural model of uncertainty attitudes that allows us to measure a preference for or an aversion against the source of uncertainty, as well as optimism or pessimism regarding the desired outcome. We document systematic attitudes towards strategic uncertainty that vary across contexts. Under strategic complementarity [substitutability], the majority of participants tend to be pessimistic [optimistic] regarding the desired outcome. However, preferences for the source of uncertainty are distributed around zero.

Two main factors of leadership impact are the ability to induce high contributions by all group members and the (expected) fair use of power. Participants in our experiment decide about contributions to a public good. After all contributions are made, the leader can choose how much of the joint earnings to assign to herself; the remainder is distributed equally among the followers. Using machine learning techniques, we study whether the content of initial open statements by the group members predicts their behavior as a leader and whether groups are able to identify such clues and endogenously appoint a “good” leader to solve the dilemma. We find that leaders who promise fairness are more likely to behave fairly, and that followers appoint as leaders those who write more explicitly about fairness and efficiency. However, in their contribution decision, followers focus on the leader’s first-move contribution and place less importance on the content of the leader’s statements.

We study one particular context in which ignorance can be beneficial: iterated strategic interactions in which voluntary cooperation may be sustained into the final round if players voluntarily forego knowledge about the time horizon. We experimentally examine this option to remain ignorant about the time horizon in a finitely repeated two-person prisoners’ dilemma game. We confirm that pairs without horizon knowledge avoid the drop in cooperation that otherwise occurs toward the end of the game. However, this effect is superposed by cooperation declining more rapidly in pairs without horizon knowledge during the middle phase of the game, especially if players do not know that the other player also wanted to remain ignorant of the time horizon.

T2 - CEPA Discussion Papers N2 - Envy is an unpleasant emotion. If individuals anticipate that comparing their payoff with the (potentially higher) payoff of others will make them envious, they may want to actively avoid information about other people’s payoffs. Given the opportunity to reduce another person’s payoff, an individual’s envy may trigger behavior that is detrimental to welfare. In this case, if individuals anticipate that they will react in a welfare-reducing way, they may also avoid information about other people’s payoffs from the outset. We investigated these two hypotheses using three experiments. We found that 13% of our potentially envious subjects avoided information when they did not have the opportunity to reduce another participant’s payoff. Psychological scales do not explain this behavior. We also found that voluntarily uninformed subjects did neither deduct less of the payoff nor less frequently than subjects who could not avoid the information.

We propose a mechanism of ex-post voluntary transfers designed to circumvent these coordination problems and ask whether it can do so. To test this, we implement a controlled laboratory experiment based on a repeatedly played Ultimatum Game with a stochastic endowment. Contrary to our hypothesis, we find that allowing voluntary transfers does not entail an efficiency increase. We suggest and analyze two main reasons for this finding: First, the stochastic uncertainty forces proposers to accept high strategic uncertainty if they intend to cooperate by claiming a low amount (which many proposers do not). Second, many responders behave only incompletely conditionally cooperative by transferring too little (which hinders cooperation in future periods).

In a prisoner’s dilemma experiment, we show that communication not only makes individuals more optimistic that their partner will cooperate but also increases the precision of this belief, thereby reducing strategic uncertainty. To disentangle the shift in mean beliefs from the increase in precision, we elicit beliefs and precision in a two-stage procedure and in three situations: without communication, before communication, and after communication.

Whereas legal actors on the international level might normatively aim for law to have a similar effect to that of domestic law, the way in which international and supranational law can fulfil these potential functions is different. Accordingly, this paper argues that an awareness with regard to the particularities and challenges that the potential functions of law encounter in the international and supranational context is needed. Moreover, it suggests an analytical lens to conceptually frame and locate current developments, offering a broader perspective on, or even an element of explication for, the apparent crisis that law is currently facing on the international and supranational scale. After describing the potential functions of law on an abstract scale and grouping them into analytical categories, the paper uses these categories as a lens in order to assess in which way international law can fulfil these potential functions, where priorities regarding certain functions might differ and where some aspects of these functions are challenged when law is made and applied in the international and supranational sphere.

The paper provides for an analysis of the facts behind the CARICOM claim and asks whether the law of state responsibility is able to provide for the demanded compensation. As the intertemporal principle generally prohibits retroactive application of today’s international rules, the paper argues that the complete claim must be based on the law of state responsibility governing in the time of the respective conduct. An inquiry into the history of primary (prohibition of slavery and genocide) as well as secondary rules of State responsibility reveals that both sets of rules were underdeveloped or non-existent at the times of slavery and alleged (native) genocides. Therefore, the author concludes that the CARICOM claim is legally flawed but nevertheless worth the attention as it once again exposes imperial and colonial injustices of the past and their legitimization by historical international law and international/natural lawyers.

Die Indikatoren Fraktionsgröße, Positionsmenge oder Engagementlänge sollen aufzeigen, in welchem konkreten Rahmen Veränderungen nötig und auch gewollt sind. Die Arbeit soll andere Städte zur Überprüfung ihrer eigenen Räte anregen. Daraus ergibt sich die Frage, ob die Belastung der Mitglieder der Stadträte und Stadtverordnetenversammlungen so groß geworden ist, dass Deutschland gar eine dritte föderale Ebene benötigt, um die Aufgaben zu bewältigen. Ist nicht eine schleichende dritte Ebene in der Realität bereits vorhanden.

Yet, appraisal varies regarding its extent and seriousness: Is it merely a rough time or are we standing on the edge of destruction? The article will trace developments inside as well as outside the WTO in order to assess the magnitude of the crisis. It will be argued that while certain developments inside the organisation, when seen in accumulation would already warrant serious attention, only together with developments taking place outside of the WTO, the two strands of developments unfold their full potential for the crisis. The overall situation renders the WTO in a difficult position, as it is currently unable to adapt to these challenges, while keeping calm and carrying on might similarly further the crisis. While States might improve and further develop their trade relations in bi- and plurilateral agreements, it is only the WTO that reflects and stands for the multilateral post (cold) war order.

Our conceptual framework differentiates between the investment risk and insurance mechanisms underpinning training decisions. Investment risk leads risk-averse workers to train less; they undertake more training if it insures them against future losses. We use the German Socio-Economic Panel (SOEP) to demonstrate that risk affinity is associated with more training, implying that, on average, investment risks dominate the insurance benefits of training. Crucially, this relationship is evident only for general training; there is no relationship between risk attitudes and specific training. Thus, as expected, risk preferences matter more when skills are transferable – and workers have a vested interest in training outcomes – than when they are not. Finally, we provide evidence that the insurance benefits of training are concentrated among workers with uncertain employment relationships or limited access to public insurance schemes.

Our conceptual framework links managers’ risk preferences to firms’ training decisions through the bonuses they expect to receive. Risk-averse managers are expected to select workers with low turnover risk and invest in specific rather than general training. Empirical evidence supporting these predictions is provided using a novel vignette study embedded in a nationally representative survey of firm managers. Risk-tolerant and risk-averse decision makers have significantly different training preferences. Risk aversion results in increased sensitivity to turnover risk. Managers who are risk-averse offer significantly less general training and, in some cases, are more reluctant to train workers with a history of job mobility. All managers, irrespective of their risk preferences, are sensitive to the investment risk associated with training, avoiding training that is more costly or targets those with less occupational expertise or nearing retirement. This suggests the risks of training are primarily due to the risk that trained workers will leave the firm (turnover risk) rather than the risk that the benefits of training do not outweigh the costs (investment risk).

Using the principal-agent setting of the delegation game, we test four key channels that conceptually link locus of control to decision-making: (i) preference for agency; (ii) optimism and (iii) confidence regarding the return to effort; and (iv) illusion of control. Knowing the return and cost of stated effort, principals either retain or delegate the right to make an investment decision that generates payoffs for themselves and their agents. Extending the game to the context in which the return to stated effort is unknown allows us to explicitly study the relationship between locus of control and beliefs about the return to effort. We find that internal locus of control is linked to the preference for agency, an effect that is driven by women. We find no evidence that locus of control influences optimism and confidence about the return to stated effort, or that it operates through an illusion of control.

T2 - CEPA Discussion Papers N2 - As the policy debate on entrepreneurship increasingly centers on firm growth in terms of job creation, it is important to better understand which variables influence the first hiring decision and which ones influence the subsequent survival as an employer. Using the German Socio-economic Panel (SOEP), we analyze what role individual characteristics of entrepreneurs play in sustainable job creation. While human and social capital variables positively influence the hiring decision and the survival as an employer in the same direction, we show that none of the personality traits affect the two outcomes in the same way. Some traits are only relevant for survival as an employer but do not influence the hiring decision, other traits even unfold a revolving door effect, in the sense that employers tend to fail due to the same characteristics that positively influenced their hiring decision.

It is thus a crucial factor for entrepreneurs when pursuing and exploiting their business opportunities and to realize potential economic gains and benefits. Using rich data on a representative sample of German business founders, we investigate the determinants of entrepreneurial persistence. Next to observed survival we also construct a hybrid persistence measure capturing also the motivational dimension of persistence. We analyze the influence of individual-level (human capital and personality) and business-related characteristics on both measures as well as their relative importance. We find that the two indicators emphasize different aspects of persistence. For the survival indicator, the predictive power is concentrated in business characteristics and human capital, while for hybrid persistence, the dominant factors are business characteristics and personality. Finally, we show that results are heterogeneous across subgroups. In particular, formerly-unemployed founders do not differ in survival chances, but they are more likely to lack a high psychological commitment to their business ventures.

Using representative longitudinal survey data from Germany, we reveal differential effects by gender: whereas self-employed women experienced a substantial deterioration in their mental health, self-employed men displayed no significant changes up to early 2021. Financial losses are important in explaining these differences. In addition, we find larger mental health responses among self-employed women who were directly affected by government-imposed restrictions and bore an increased childcare burden due to school and daycare closures. We also find that self-employed individuals who are more resilient coped better with the crisis.

BT - Examining the Role of Locus of Control for Alcohol Consumption T2 - CEPA Discussion Papers N2 - Unhealthy behavior can be extremely costly from a micro- and macroeconomic perspective and exploring the determinants of such behavior is highly important from an economist’s point of view. We examine whether locus of control (LOC) can explain alcohol consumption as an important domain of health behavior. LOC measures how much an individual believes that she is in control of the consequences of her own actions for her life’s future outcomes. While earlier literature showed that an increasing internal LOC is associated with increased health-conscious behavior in domains such as smoking, exercise or diets, we find that drinking seems to be different. Using German panel data from the Socio-Economic Panel (SOEP) we find a significant positive effect of having an internal LOC on the probability of moderate and regular drinking. We suggest and discuss two likely mechanisms for this relationship and find interesting gender differences. While social investments play an important role for both men and women, risk perceptions are especially relevant for men.

As such beliefs reflect how individuals behave, think, and act, they are key for successful entrepreneurial activities. While existing literature mainly analyzes the influence of the task-related construct of entrepreneurial self-efficacy, we take a different perspective and investigate, based on a representative sample of 1,405 German business founders, how the personality characteristic of generalized self-efficacy influences start-up performance as measured by a broad set of business outcomes up to 19 months after business creation. Outcomes include start-up survival and entrepreneurial income, as well as growth-oriented outcomes such as job creation and innovation. We find statistically significant and economically important positive effects of high scores of self-efficacy on start-up survival and entrepreneurial income, which become even stronger when focusing on the growth-oriented outcome of innovation. Furthermore, we observe that generalized self-efficacy is similarly distributed between female and male business founders, with effects being partly stronger for female entrepreneurs. Our findings are important for policy instruments that are meant to support firm growth by facilitating the design of more target-oriented offers for training, coaching, and entrepreneurial incubators.

In this context, we investigate whether the motives of becoming an entrepreneur influence the subsequent entrepreneurial development. In our analysis, we examine a broad range of business outcomes including survival and income, as well as job creation, expansion and innovation activities for up to 40 months after business formation. Using self-determination theory as conceptual background, we aggregate the start-up motives into a continuous motivational index. We show – based on a unique dataset of German start-ups from unemployment and non-unemployment – that the later business performance is better, the higher they score on this index. Effects are particularly strong for growth oriented outcomes like innovation and expansion activities. In a next step, we examine three underlying motivational categories that we term opportunity, career ambition, and necessity. We show that individuals driven by opportunity motives perform better in terms of innovation and business expansion activities, while career ambition is positively associated with survival, income, and the probability of hiring employees. All effects are robust to the inclusion of a large battery of covariates that are proven to be important determinants of entrepreneurial performance.

We exploit regional variation in the promotion of mobility programs along administrative borders of German employment agency districts to investigate the causal effect of offering such financial incentives on the job search behavior and labor market integration of unemployed workers. We show that promoting mobility – as intended – causes job seekers to increase their search radius, apply for and accept distant jobs. At the same time, local job search is reduced with adverse consequences for reemployment and earnings. These unintended negative effects are provoked by spatial search frictions. Overall, the unconditional provision of mobility programs harms the welfare of unemployed job seekers.

BT - The Long-Term Business and Innovation Potential of Subsidized Start-Ups out of Unemployment T2 - CEPA Discussion Papers N2 - From an active labor market policy perspective, start-up subsidies for unemployed individuals are very effective in improving long-term labor market outcomes for participants. From a business perspective, however, the assessment of these public programs is less clear since they might attract individuals with low entrepreneurial abilities and produce businesses with low survival rates and little contribution to job creation, economic growth, and innovation. In this paper, we use a rich data set to compare participants of a German start-up subsidy program for unemployed individuals to a group of regular founders who started from nonunemployment and did not receive the subsidy. The data allows us to analyze their business performance up until 40 months after business formation. We find that formerly subsidized founders lag behind not only in survival and job creation, but especially also in innovation activities. The gaps in these business outcomes are relatively constant or even widening over time. Hence, we do not see any indication of catching up in the longer run. While the gap in survival can be entirely explained by initial differences in observable start-up characteristics, the gap in business development remains and seems to be the result of restricted access to capital as well as differential business strategies and dynamics. Considering these conflicting results for the assessment of the subsidy program from an ALMP and business perspective, policy makers need to carefully weigh the costs and benefits of such a strategy to find the right policy mix.

By analogy to medical treatments, the individual exposure to these tools may have side effects. We study effects on health using individual-level population registers on labor market events outcomes, drug prescriptions and sickness absence, comparing outcomes before and after exposure to training and sanctions. We find that training improves cardiovascular and mental health and lowers sickness absence. The results suggest that this is not due to improved employment prospects but rather to instantaneous features of participation such as, perhaps, the adoption of a more rigorous daily routine. Unemployment benefits sanctions cause a short-run deterioration of mental health, possibly due higher stress levels, but this tapers out quickly.

It plays a significant role in the business organization’s innovation process and the recognition of new business opportunities. Drawing upon the cumulative process model of creativity in entrepreneurship, we hypothesize that divergent thinking has a lasting effect on post-launch entrepreneurial outcomes related to innovation and growth, but that this relation might not always be linear. Additionally, we hypothesize that domain-specific experience has a moderating role in this relation. We test our hypotheses based on a representative longitudinal sample of 457 German business founders, which we observe up until 40 months after start-up. We find strong relative effects for innovation and growth outcomes. For survival we find conclusive evidence for non-linearities in the effects of divergent thinking. Additionally, we show that such effects are moderated by the type of domain-specific experience that entrepreneurs gathered pre-launch, as it shapes the individual’s ideational abilities to fit into more sophisticated strategies regarding entrepreneurial creative achievement. Our findings have relevant policy implications in characterizing and identifying business start-ups with growth and innovation potential, allowing a more efficient allocation of public and private funds.

We discuss the short-run effects of this new minimum wage on a wide set of socio-economic outcomes, such as employment and working hours, earnings and wage inequality, dependent and self-employment, as well as reservation wages and satisfaction. We also discuss difficulties in the implementation of the minimum wage and the measurement of its effects related to non-compliance and suitability of data sources. Two years after the minimum wage introduction, the following conclusions can be drawn: while hourly wages increased for low-wage earners, some small negative employment effects are also identifiable. The effects on aspired goals, such as poverty and inequality reduction, have not materialized in the short run. Instead, a tendency to reduce working hours is found, which alleviates the desired positive impact on monthly income. Additionally, the level of non-compliance was substantial in the short run, thus drawing attention to problems when implementing such a wide-reaching policy.

As experimental variation in program design is unavailable, we exploit the 2011 reform of the current German SUS program for the unemployed which strengthened case-workers’ discretionary power, increased entry requirements and reduced monetary support. We estimate the impact of the reform on the program’s effectiveness using samples of participants and non-participants from before and after the reform. To control for time-constant unobserved heterogeneity as well as differential selection patterns based on observable characteristics over time, we combine Difference-in-Differences with inverse probability weighting using covariate balancing propensity scores. Holding participants’ observed characteristics as well as macroeconomic conditions constant, the results suggest that the reform was successful in raising employment effects on average. As these findings may be contaminated by changes in selection patterns based on unobserved characteristics, we assess our results using simulation-based sensitivity analyses and find that our estimates are highly robust to changes in unobserved characteristics. Hence, the reform most likely had a positive impact on the effectiveness of the program, suggesting that increasing entry requirements and reducing support in-creased the program’s impacts while reducing the cost per participant.

Using propensity score matching (PSM) as our main empirical approach, we provide estimates of long-term effects of the post-reform subsidy on individual employment prospects and labor market earnings up to 40 months after entering the program. Our results suggest large and persistent long-term effects of the subsidy on employment probabilities and net earned income. These effects are larger than what was estimated for the pre-reform program. Extensive sensitivity analyses within the standard PSM framework reveal that the results are robust to different choices regarding the implementation of the weighting procedure and also with respect to deviations from the conditional independence assumption. As a further assessment of the results’ sensitivity, we go beyond the standard selection-on-observables approach and employ an instrumental variable setup using regional variation in the likelihood of receiving treatment. Here, we exploit the fact that the reform increased the discretionary power of local employment agencies in allocating active labor market policy funds, allowing us to obtain a measure of local preferences for SUS as the program of choice. The results based on this approach give rise to similar estimates. Thus, our results indicating that SUS are still an effective active labor market program after the reform do not appear to be driven by “hidden bias”.

BT - A Rigorous Look at (Un-)Intended Consequences of Labor Market Policies T2 - CEPA Discussion Papers N2 - We estimate the long-term effects of start-up subsidies (SUS) for the unemployed on subjective outcome indicators of well-being, as measured by the participants’ satisfaction in different domains. This extends previous analyses of the current German SUS program (“Gründungszuschuss”) that focused on objective outcomes – such as employment and income – and allows us to make a more complete judgment about the overall effects of SUS at the individual level. This is especially important because subsidizing the transition into self-employment may have unintended adverse effects on participants’ well-being due to its risky nature and lower social security protection, especially in the long run. Having access to linked administrative-survey data providing us with rich information on pre-treatment characteristics, we base our analysis on the conditional independence assumption and use propensity score matching to estimate causal effects within the potential outcomes framework. We find long-term positive effects on job satisfaction but negative effects on individuals’ satisfaction with their social security situation. Further findings suggest that the negative effect on satisfaction with social security may be driven by negative effects on unemployment and retirement insurance coverage. Our heterogeneity analysis reveals substantial variation in effects across gender, age groups and skill levels. The sensitivity analyses show that these findings are highly robust.

T2 - CEPA Discussion Papers N2 - In many countries, women are over-represented among low-wage employees, which is why a wage floor could benefit them particularly. Following this notion, we analyse the impact of the German minimum wage introduction in 2015 on the gender wage gap. Germany poses an interesting case study in this context, since it has a rather high gender wage gap and set the minimum wage at a relatively high level, affecting more than four million employees. Based on individual data from the Structure of Earnings Survey, containing information for over one million employees working in 60,000 firms, we use a difference-in- difference framework that exploits regional differences in the bite of the minimum wage. We find a significant negative effect of the minimum wage on the regional gender wage gap. Between 2014 and 2018, the gap at the 10th percentile of the wage distribution was reduced by 4.6 percentage points (or 32%) in regions that were strongly affected by the minimum wage compared to less affected regions. For the gap at the 25th percentile, the effect still amounted to -18%, while for the mean it was smaller (-11%) and not particularly robust. We thus find that the minimum wage can indeed reduce gender wage disparities. While the effect is highest for the low-paid, it also reaches up into higher parts of the wage distribution.

The following article deals with such challenges. Therefore it firstly defines the term of privacy in general and presents an international legal framework. With whisteblower Snowden a huge political discourse was initiated and the article gives insights into its further development. In 2015 the Human Rights Council for the first time announced a special rapporteur on the right to privacy. However, the discourse is not only taking place on a political level, also civil society organizations advocate more stringent regulations and prosecutions against violations of the right to privacy. Moreover the importance of the technology sector becomes clear. Companies like Microsoft are increasingly taking responsibility to protect digital media against unjustified data misuse, surveillance, collection and storage. But whereas the IT sector is developing very quickly, legislative processes do so rather slowly. Lastly, the individual is also hold to account. To protect oneself against data misuse is to a great extent acting self-responsible. Still, therefore information on protection must be clear and accessible for everyone. N2 - Das Recht auf Privatsphäre im digitalen Zeitalter stellt die internationale Gerichtsbarkeit vor neue Herausforderungen. Der nachfolgende Artikel beschäftigt sich mit diesen Herausforderungen. Er definiert „Privatsphäre“ und zeigt internationale rechtliche Rahmenbedingungen auf. Der seit Whisteblowern wie Snowden angestoßene internationale politische Diskurs und dessen Entwicklung werden beleuchtet. Der Menschenrechtsrat der Vereinten Nationen bestimmte im April 2015 erstmals einen Sonderberichterstatter für das Recht auf Privatsphäre. Jedoch findet der Diskurs nicht nur auf politischer Ebene statt: Auch zivilgesellschaftliche Organisationen setzten sich zunehmend für strengere Vorschriften und Strafverfolgungsmaßnahmen für Verstöße gegen das Recht auf Privatsphäre ein. Zudem wird auch die Bedeutung des IT-Bereichs deutlich. Technologieunternehmen wie Microsoft sehen sich zunehmend in der Verantwortung, digitale Medien gegen nicht gerechtfertigte Datenmissbrauch, Überwachungsmaßnahmen und Datensammlung zu schützen. Der IT-Bereich entwickelt sich sehr schnell – die Gesetzgebung hingegen sehr schleppend. Zuletzt wird auch die einzelne Person in Verantwortung gezogen. Sich selbst weit möglichst gegen Datenmissbrauch zu schützen, liegt bislang in der Hand des Einzelnen. Informationen zum Schutz müssen jedoch deutlich und zugänglich sein.

The present paper examines the question whether jus cogens can discharge this function within the traditionally horizontal and decentralized international legal order. In so doing, it commences with an overview of the historical origins of peremptory norms in legal scholarship, followed by its endorsement by positive law and courts and tribunals. This analysis illustrates that there are lingering uncertainties pertaining to the process of identification of peremptory norms. Even so, the concept has been invoked in State executive practice (although infrequently) and has been endorsed by various courts. However, such invocation thus far has had a limited impact from a legal perspective. It was mainly confined to a strengthened moral appeal and did in particular not facilitate the resolution of norm conflicts. The contribution further suggests that this limited impact results from the fact that the content of peremptory obligations is either very narrow or very vague. This, in turn, implies a lack of consensus amongst States regarding the content (scope) of jus cogens, including the values underlying these norms. As a result, it is questionable whether the construct of jus cogens is able to provide meaningful legal protection against the erosion of legal norms. It is too rudimentary in character to entrench and stabilize core human rights values as the moral foundation of the international legal order.

BT - the third wave of autocratization and international organization membership T2 - IGCC series on authoritarian regimes and international organizations N2 - Democratization scholars are currently debating if we are indeed witnessing a third wave of autocratization. While this has led to an extensive debate about the future of the liberal international order, we still know relatively little about the consequences of autocratization for international organizations (IOs). In this article, we explore to what extent autocratization has led to changes in the composition of IO membership. We propose three different ways of conceptualizing autocratization of IO membership. We argue that we should move away from a dichotomous understanding of regime type and regime change, but rather focus on composition of subregime types to understand current developments. We build on updated membership data for 73 IOs through 2020 to map membership configurations based on the V-Dem Electoral Democracy Index. Contrary to current debates on the crisis of the liberal order, we find that many IOs are not (yet) affected by broad autocratization of their membership that would endanger democratic majorities or overall democratic densities. However, we also observe the disappearance of formerly homogenous democratic clubs due to democratic backsliding in a number of European and Latin American IO member states, as well as a return of autocratic clubs in Southeast Asia and Southern Africa. These findings have important implications for the broader research agenda on international democracy promotion and human right protection as well as the study of legitimacy and the effectiveness of international organizations.

An Austrian NGO filed a complaint to the Prosecutor of the International Criminal Court (ICC) against Bolsonaro in October 2021, accusing him of crimes against humanity against the backdrop of his involvement in environmental destruction. This paper deals with the question of whether this initi-ative constitutes a promising means of juridification to mitigate conflicts revolving around mass deforestation in Brazil. It thematizes attempts to juridify environmental destruction in international criminal law and examines the Climate Fund Case at the Brazilian Supreme Court. Finally, emerging problems and arguments in favour of starting preliminary examinations at the ICC against Bolsonaro are illuminated. This paper provides arguments as to why the initiative might be a promising undertaking, even though it is unlikely that Bolsonaro will be arrested.

Taking as its starting point that there now exists tentative consensus that the present system for the appointment of arbitrators either causes or exacerbates certain problematic aspects of the current ISDS system, the paper explores one option for reform, namely the introduction of an independent panel for the selection of investment arbitrators. In doing so, it is argued that a shift in the normative basis of the rules governing appointments is required in order to accommodate the principles of party autonomy and the international rule of law. Such reform, while not completely removing the initiative that parties presently enjoy, is the most efficient way to introduce rule of law considerations such as a measure of judicial independence into the current appointments system. This, it is argued, would in turn help to address some of the problematic features of the appointment of arbitrators in ISDS.

This paper considers the effects of the trade policy made by both countries participating in international trade in a spatial economic model. It can be showed that trade policy of both trade partners (tariffs of one country and export subsidies of the other country) can improve the world welfare in comparison with free trade.

N2 - Many European countries have experienced a significant increase of unemployment in recent years. This paper reviews several theoretical models that try to explain this phenomenon. Predominantly, these models claim a link between the poor performance of European labor markets and the high level of market regulation. Commonly referred to as the Eurosclerosis debate, prominent approaches consider insider-outsider relationships, search-models, and the influence of hiring and firing costs on equilibrium employment. The paper presents empirical evidence of each model and studies the relevance of the identified rigidities as a determinant of high unemployment in Europe. Furthermore, a case study analyzes the unemployment problem in Germany and critically discusses new reform efforts. In particular this section analyzes whether the recently enacted Hartz reforms can induce higher employment.

Die Wettbewerbsökonomik hat ihm außerordentlich viel zu verdanken. Besondere Bekanntheit erlangte seine Kontroverse mit Erhard Kantzenbach über das adäquate Leitbild der Wettbewerbspolitik. Hoppmanns Leitbild der Wettbewerbsfreiheit entstand ab 1966 vornehmlich als Reaktion auf Kantzenbachs Leitbild der optimalen Wettbewerbsintensität. Hoppmanns Leitbild wandte sich aber auch gegen bestimmte Workability-Konzepte, ferner gegen die mit dem neoklassischen Modell der vollkommenen Konkurrenz verbundenen Gleichgewichtsvorstellungen. Wegen der für die Entwicklung der Wettbewerbspolitik in Deutschland bedeutsamen Kontroverse zwischen Hoppmann und Kantzenbach wollen wir uns im Folgenden auf deren Leitbilder konzentrieren. Zunächst werden beide Konzeptionen rekapituliert und sodann gegenübergestellt. Schließlich wird nach ihrer Bedeutung für die Theorie und Praxis der Wettbewerbspolitik gefragt.

Digital financial platforms that crowdfund equity for entrepreneurs have emerged globally, yet they remain poorly understood. We model equity crowdfunding in terms of the relationship between the number of investors and the amount of money raised per pitch. We examine heterogeneity in the average amount raised per pitch that is associated with differences across three countries and seven platforms. Using a novel dataset of successful fundraising on the most prominent platforms in the UK, Germany, and the USA, we find the underlying relationship between the number of investors and the amount of money raised for entrepreneurs is loglinear, with a coefficient less than one and concave to the origin. We identify significant variation in the average amount invested in each pitch across countries and platforms. Our findings have implications for market actors as well as regulators who set competitive frameworks.

From a macroeconomic perspective, it is important to understand how these policies perform under uncertainty, how they affect short-run dynamics and to what extent they have distributional effects. In addition, uncertainties directly associated with climate policies, such as uncertainty about the carbon budget or emission intensities, become relevant aspects. We study the implications of emission reduction schemes within a Two-Agent New-Keynesian (TANK) model. This quantitative exercise, based on data for the German economy, provides various insights. In the light of frictions and fluctuations, compared to other instruments, a carbon price (i.e. tax) is associated with lower volatility in output and consumption. In terms of aggregate welfare, price instruments are found to be preferable. Conditional on the distribution of revenues from climate policies, quantity instruments can exert regressive effects, posing a larger economic loss on wealth-poor households, whereas price instruments are moderately progressive. Finally, we find that unexpected changes in climate policies can induce substantial aggregate adjustments. With uncertainty about the carbon budget, the costs of adjustment are larger under quantity instruments.

Potential efficiency gains from reducing distortionary taxes and the distributional implications of different revenue recycling schemes are currently debated. To account for households heterogeneity and dynamic trade-offs, we study the macroeconomic and welfare performance of different revenue recycling schemes using an Environmental Two-Agent New-Keynesian model, calibrated on the German economy. We find that, in the long run, welfare gains are higher when revenues are used to reduce distortionary taxes on capital, but this comes at the cost of higher inequality: while all households prefer labor income tax reductions to lump-sum transfers, only financially unconstrained households are better off when reducing taxes on capital income. Interestingly, we find that over the transition period relevant to meet short-medium run climate targets, labor income tax cuts are the most efficient and equitable instrument.

BT - On the Inflationary Effects of Military Conflicts T2 - CEPA Discussion Papers N2 - Military conflicts and wars affect a country’s development in various dimensions. Rising inflation rates are a potentially important economic effect associated with conflict. High inflation can undermine investment, weigh on private consumption, and threaten macroeconomic stability. Furthermore, these effects are not necessarily restricted to the locality of the conflict, but can also spill over to other countries. Therefore, to understand how conflict affects the economy and to make a more comprehensive assessment of the costs of armed conflict, it is important to take inflationary effects into account. To disentangle the conflict-inflation-nexus and to quantify this relationship, we conduct a panel analysis for 175 countries over the period 1950–2019. To capture indirect inflationary effects, we construct a distance based spillover index. In general, the results of our analysis confirm a statistically significant positive direct association between conflicts and inflation rates. This finding is robust across various model specifications. Moreover, our results indicate that conflict induced inflation is not solely driven by increasing money supply. Furthermore, we document a statistically significant positive indirect association between conflicts and inflation rates in uninvolved countries.

BT - The Behavioral Effects of Birthright Citizenship on Immigrant Youth T2 - CEPA Discussion Papers N2 - Inequality of opportunity, particularly when overlaid with socioeconomic, ethnic, or cultural differences, may limit the scope of cooperation between individuals. A central question, then, is how to overcome such obstacles to cooperation. We study this question in the context of Germany, by asking whether the propensity of immigrant youth to cooperate with native peers was affected by a major integration reform: the introduction of birthright citizenship. Our unique setup exploits data from a large-scale lab-in-the-field experiment in a quasi-experimental evaluation framework. We find that the policy caused male, but not female, immigrants to significantly increase their cooperativeness toward natives. We show that the increase in out-group cooperation among immigrant boys is an outcome of more trust rather than a reflection of stronger other- regarding preferences towards natives. In exploring factors that may explain these behavioral effects, we present evidence that the policy also led to a near-closure of the educational achievement gap between young immigrant men and their native peers. Our results highlight that, through integration interventions, governments can modify prosocial behavior in a way that generates higher levels of efficiency in the interaction between social groups.

In a first-best setting, the optimal use of CDR is achieved by a removal subsidy that equals the optimal carbon tax and marginal damages. We derive second-best subsidies for CDR when no global carbon price exists but a national government implements a unilateral climate policy. We find that the optimal carbon tax differs from an optimal CDR subsidy because of carbon leakage, terms-of-trade and fossil resource rent dynamics. First, the optimal removal subsidy tends to be larger than the carbon tax because of lower supply-side leakage on fossil resource markets. Second, terms-of-trade effects exacerbate this wedge for net resource exporters, implying even larger removal subsidies. Third, the optimal removal subsidy may fall below the carbon tax for resource-poor countries when marginal environmental damages are small.

In view of these potential trade-offs, many countries are discussing the optimal design of parental leave policies. We analyze the impact of a major parental leave reform on mothers’ long-term earnings. The 2007 German parental leave reform replaced a means-tested benefit with a more generous earnings-related benefit that is granted for a shorter period of time. Additionally, a “daddy quota” of two months was introduced. To identify the causal effect of this policy on long-run earnings of mothers, we use a difference-in-difference approach that compares labor market outcomes of mothers who gave birth just before and right after the reform and nets out seasonal effects by including the year before. Using administrative social security data, we confirm previous findings and show that the average duration of employment interruptions increased for high-income mothers. Nevertheless, we find a positive long-run effect on earnings for mothers in this group. This effect cannot be explained by changes in working hours, observed characteristics, changes in employer stability or fertility patterns. Descriptive evidence suggests that the stronger involvement of fathers, incentivized by the “daddy months”, could have facilitated mothers’ re-entry into the labor market and thereby increased earnings. For mothers with low prior-to-birth earnings, however, we do not find any beneficial labor market effects of this parental leave reform.

Die gängigen Modelle zeigen aber weder, wie dauerhafte Lohnsatzdifferenzen ohne vollständige Agglomeration entstehen, noch wird die Frage beantwortet, in welcher der betrachteten Regionen sich eine Agglomeration bildet. Diese Lücke wird hier geschlossen, indem das Modell von Ludema und Wooton (1997) erweitert und anschließend auf die Situation in Deutschland angewendet wird.

Die resultierenden Gleichgewichte hängen von der Höhe der Transportkosten ab, die allerdings in beiden Sektoren als gleich hoch unterstellt werden. Der vorliegende Beitrag erweitert dieses Modell um die Möglichkeit sektoral unterschiedlicher Transportkosten. Da eine analytische Lösung nichtmöglich ist, wird eine geeignete Simulationsmethode entwickelt. Anhand von Abbildungen wird dargestellt, welche Gleichgewichte sich bei verschiedenen Werten für die beiden Transportkostensätze ergeben.

Our findings show that the selection-corrected gender wage gap is much larger than the one observed in the data, which is mainly due to large positive selection of women into full-time employment. However, we show that selection-corrected wages of male and female workers at the lower half of the distribution have moderately converged over time. The reason for this development have been changes in the composition of the male full-time employment force over time, which in spite of the rather constant male full-time employment rate, have given place to a small but rising selection bias in male observed wages. In the upper half of the wage distribution, however, neither the observed nor the selection-corrected gender wage gap has narrowed over time.

Adopting the 3-stage CDM model, we explore the link between R&D, innovation, and productivity for different size groups of Greek manufacturing firms during the prolonged crisis. At the first stage, we find that the continuation of the crisis is harmful for the R&D engagement of smaller firms while it increased the willingness for R&D activities among the larger ones. At the second stage, among smaller firms the knowledge production remains unaffected by R&D investments, while among larger firms the R&D decision is positively correlated with the probability of producing innovation, albeit the relationship is weakened as the crisis continues. At the third stage, innovation output benefits only larger firms in terms of labor productivity, while the innovation-productivity nexus is insignificant for smaller firms during the lasting crisis.

BT - The Forward-Looking Effects of Increasing the Retirement Age on (Un)employment Behaviour T2 - CEPA Discussion Papers N2 - Leveraging two cohort-specific pension reforms, this paper estimates the forward-looking effects of an exogenous increase in the working horizon on (un)employment behaviour for individuals with a long remaining statutory working life. Using difference-in-differences and regression discontinuity approaches based on administrative and survey data, I show that a longer legal working horizon increases individuals’ subjective expectations about the length of their work life, raises the probability of employment, decreases the probability of unemployment, and increases the intensity of job search among the unemployed. Heterogeneity analyses show that the demonstrated employment effects are strongest for women and in occupations with comparatively low physical intensity, i.e., occupations that can be performed at older ages.

BT - The Effect of a Public Transport Subsidy on Air Quality T2 - CEPA Discussion Papers N2 - This paper provides novel evidence on the impact of public transport subsidies on air pollution. We obtain causal estimates by leveraging a unique policy intervention in Germany that temporarily reduced nationwide prices for regional public transport to a monthly flat rate price of 9 Euros. Us-ing DiD estimation strategies on air pollutant data, we show that this intervention causally reduced a benchmark air pollution index by more than six percent. Our results illustrate that public transport subsidies – especially in the context of spatially constrained cities – offer a viable alterna-tive for policymakers and city planers to improve air quality, which has been shown to crucially affect health outcomes.

This is problematic because both theoretical and empirical evidence show that the position in the wealth and income distribution can significantly diverge.We measure ex-ante IOp in net wealth for Germany using data from the Socio-Economic Panel (SOEP). Ex-ante IOp is defined as the contribution of circumstances to the inequality in net wealth before effort is exerted. The SOEP allows for a direct mapping from individual circumstances to individual net wealth and for a detailed decomposition of net wealth inequality into a variety of circumstances; among them childhood background, intergenerational transfers, and regional characteristics. The ratio of inequality of opportunity to total inequality is stable from 2002 to 2019. This is in sharp contrast to labor earnings, where ex-ante IOp is declining over time. Our estimates suggest that about 62% of the inequality in net wealth is due to circumstances. The most important circumstances are intergenerational transfers, parental occupation, and the region of birth. In contrast, gender and individuals’ own education are the most important circumstances for earnings.
