  abstract  = {Against the background of the increasingly discussed "Linguistic Saving Hypothesis" (Chen, 2013), I studied whether the targeted use of a present tense (close tense) and a future tense (distant tense) within the same language have an impact on intertemporal decision-making. In a monetarily incentivized laboratory experiment in Germany, I implemented two different treatments on intertemporal choices. The treatments differed in the tense in which I referred to future rewards. My results show that individuals prefer to a greater extent rewards which are associated with a present tense (close tense). This result is in line with my prediction and the first empirical support for the Linguistic Saving Hypothesis within one language. However, this result holds exclusively for males. Females seem to be unaffected by the linguistic manipulation. I discuss my findings in the context of "gender-as-culture" as well as their potential policy-implications.},

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.},

For identification of a causal effect we employ a panel model with establishment fixed effects and industry-specific time dummies. Our results show that a higher share of women in management significantly reduces the gender pay gap within the firm. An increase in the share of women in first-level management e.g. from zero to above 33 percent decreases the adjusted gender pay gap from a baseline of 15 percent by 1.2 percentage points, i.e. to roughly 14 percent. The effect is stronger for women in second-level than first-level management, indicating that women managers with closer interactions with their subordinates have a higher impact on the gender pay gap than women on higher management levels. The results are similar for East and West Germany, despite the lower gender pay gap and more gender egalitarian social norms in East Germany. From a policy perspective, we conclude that increasing the number of women in management positions has the potential to reduce the gender pay gap to a limited extent. However, further policy measures will be needed in order to fully close the gender gap in pay.},

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.},

  abstract  = {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.},

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.},

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.},

If UNHCR is to play an active role in fu-ture refugee policies and become the lead agency it once was, a new daring and innovative approach has to emerge in order to readapt to the power relations that prevail in the twenty-first century.},

The paper presents empirical evidence of each model and studies the relevance of the identified rigidities as a determinant of high unemployment in Europe.

  abstract  = {For the United States the 'international law of global security' is, in a unique sense, synonymous with the entire project of constructing global legal order. Uniquely preponderant power enjoyed since the end of the Second World War has allowed US preferences to manifest not merely in specific rules and regimes, but in purposive development of the entire structure of global legal order to favour American security interests. Perceptions of a recent decline in this order now find expression in advocacy for a 'liberal' or 'rules-based' international order, as the claimed foundation for global prosperity and security. This working paper seeks to map out the parameters of US contributions to the global security order by uncovering the strategic and political foundations of its engagement with the international law of global security. The paper begins by reflecting on competing US conceptions of the relationship between national security and global order as they evolved across the twentieth century. The focus then turns to three significant trends defining the contemporary field. First are US attitudes toward multilateral institutions and global security, and the ongoing contest between beliefs that they are mutually reinforcing versus beliefs that US security and global institutions sit in zero-sum opposition. Second is the impact of the generational 'War on Terror', which has yielded more permissive interpretation and development of laws governing the global use of violence. The final trend is that towards competitive geopolitical interests restructuring international law, which are evident across diverse areas ranging from global economics, to cybersecurity, to the fragmentation of global order into spheres of influence. Looking ahead, a confluence of rising geopolitical competitors with divergent legal conceptions, and conflicted domestic support for the legitimacy and desirability of US global leadership, emerge as leading forces already reshaping the global security order.},

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.},

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 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.},

  abstract  = {Over the last few decades, the methodology for the identification of customary international law (CIL) has been changing. 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.},

  abstract  = {This paper evaluates the construction of the rights of human rights defenders within international law and its shortcomings in protecting women. 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.},

  abstract  = {In Germany, the productivity of professional services, a sector dominated by micro and small firms, declined by 40 percent between 1995 and 2014. This productivity decline also holds true for professional services in other European countries. Using a German firm-level dataset of 700,000 observations between 2003 and 2017, we analyze this largely uncovered phenomenon among professional services, the 4th largest sector in the EU15 business economy, which provide important intermediate services for the rest of the economy. We show that changes in the value chain explain about half of the decline and the increase in part-time employment is a further minor part of the decline. In contrast to expectations, the entry of micro and small firms, despite their lower productivity levels, is not responsible for the decline. We also cannot confirm the conjecture that weakening competition allows unproductive firms to remain in the market.},

It seeks to know whether the establishment of the PSC in 2002 is leading or has led to a rise or a decline of collective security in Africa. It is demonstrated that in regard to its relative legal and institutional robustness, the PSC can be perceived as a rise of collective security compared with its predecessor, the Central Organ of the Organisation of African Unity (OAU). However, it stagnates in terms of quantity and quality of actions on the ground. The main problem lies in the lack of sufficient operational autonomy from member states and international partners, such as the United Nations. Therefore, the PSC's contribution to the maintenance of peace and security, and so the rise of the international rule of law in Africa is limited. The continent is still a war-torn region, affected by political crises and the expansion of terrorism in many countries. To solve this problem, AU member states should strengthen the PSC's capacity, starting with the quick operationalisation of the African Standby Force. The implementation of the 2016 decision on alternative sources of financing AU's institutions and activities is also a priority. In this regard, the political will of African states that may show that they want to take their organisation more seriously is required. This can further the AU self-reliance policy in collective security though the promotion of African solutions to African problems, and reduce the burden of the United Nations and other non-African actors' interventions in the continent.},

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.},

The paper discusses how it can be determined whether this form of international law continues to unfold, and whether we are witnessing challenges to this order which could give rise to more fundamental reassessments.},

The picture which emerges only partly fits the widespread narrative of "from self-interest to community interest". Whereas the Commission has recognized, or developed, certain primary rules which more fully articulate community interests, it has been reluctant to reformulate secondary rules of international law, with the exception of jus cogens. The Commission has more recently rather insisted that the traditional State-consent-oriented secondary rules concerning the formation of customary international law and regarding the interpretation of treaties continue to be valid in the face of other actors and forms of action which push towards the recognition of more and thicker community interests.},

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.},

In this context, we investigate whether the motives of becoming an entrepreneur influence the subsequent entrepreneurial development.

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.},

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.},

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.},

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.

This is not dependent on Parliament's incorporation of treaty obligations into domestic law. It is the correlative consequence of the allocation to the Executive of the power to conduct foreign relations. The paper develops this argument in response to recent debate in the United Kingdom on whether Ministers have an obligation to comply with international law-a reference that the Government removed from the Ministerial Code.

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.},

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.},

International law places checks upon the exercise of withdrawal, recognising that it is an act that of its nature affects the interests of other States parties, which have a collective interest in constraining withdrawal. National courts have a complementary function in restraining unilateral withdrawal in order to support the domestic constitution. The arguments advanced against international adjudication in the name of popular democracy at the national level can serve as a cloak for the exercise of executive power unrestrained by law. The submission by States of their disputes to peaceful settlement through international adjudication is central, not incidental, to the successful operation of the international legal system.},

  abstract  = {In the first part of the report of the GTZ expert group an overview on the basics of integration and tax harmonisation within a common market is given. Chapter II. concentrates on the problems of national and international tax law regarding double taxation before the harmonisation process within the EU is described in detail. This process is not a best practice example but at least the experiences made in the course of the last five decades are interesting enough and might contribute important information for regions, which more or less recently have started a similar endeavour. The harmonisation needs are discussed for value added taxation (VAT), excise taxation, and income taxation. The problems of tax administrations, procedures laws, taxpayers' rights and obligations as well as tax compliance are also taken into consideration. The second part of the study reviews the national tax systems within the EAC member countries. Before the single taxes are described in more detail, the macroeconomic situation is illuminated by some basic figures and the current stand of the inner-community integration analysed. Then the single tax bases and tax rates are confronted to shed some light on the necessities for the development of a common market within the near future. Again the value added tax laws, excise taxes and income taxes are discussed in detail, while regarding the latter the focus is on company taxation. For a better systematic analysis the national tax laws are confronted within an overview. The chapter is closed with a summary of the tax rates applied and a rough estimation of the tax burdens within the Partner States. The third part of this report contains the policy recommendations of the expert group following the same structures as the chapters before and presenting the results for the VAT, the excises and the corporate income tax (CIT). Additionally the requirements for tax procedures and administration as well as problems of transparency and information exchange are discussed in detail before the strategic recommendations are derived in close relation to the experiences made within the EU harmonisation process. The recommendations are based on the following normative arguments: (1) Tax harmonisation is a basic requirement for economic integration. (2) Equality of taxation is an imperative of tax justice and demands the avoidance of double taxation as well as the combat of tax evasion and corruption. (3) The avoidance of harmful tax competition between the Partner States. (4) The strengthening of taxpayers' rights in tax procedures. Hence, all kinds of income, goods and services should be taxed once and only once.},

Some authors show that trade policy has negative effects on welfare, some spatial economists demonstrate that trade policy can have positive effects on welfare. 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.},

With regard to the famous three sector hypothesis, broad economic sectors were formed as required by this theory. The computation of their shares at GNP at market prices using Input-Output tables, and the adjustment of results from distortions, generated as side effects of tax avoidance practices, shows results that clearly reject claims that Russia would be on the road to a post-industrial service economy. Instead, at least until 2001, a tendency of "primarisation" could be observed, that presents Russia closer to less-developed countries.},

  abstract  = {A casual look at regional unemployment rates reveals that there are vast differences, which cannot be explained by different institutional settings. 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.},

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.},

Part I briefly reviews the theories of fiscal decentralisation and its impact on the nations' welfare considering the major challenges for a transition economy. Part II of the paper describes the general structure and scope of the government and examines the current fiscal autonomy in Mongolia focusing on the four main areas of intergovernmental relations. This paper concludes that local governments in Mongolia are still far away from having the political, administrative and fiscal autonomy. New approaches for the assignments of expenditures and revenues in Mongolia are urgently needed.},

Motivated by a stylized heterogeneous firms model of international trade with market entry costs, we consider dynamic three-way fixed effects binary choice models and study the corresponding incidental parameter problem. The standard maximum likelihood estimator is consistent under asymptotics where all panel dimensions grow at a constant rate, but it has an asymptotic bias in its limiting distribution, invalidating inference even in situations where the bias appears to be small. Thus, we propose two different bias-corrected estimators. Monte Carlo simulations confirm their desirable statistical properties. We apply these estimators in a reassessment of the most commonly studied determinants of the extensive margin of trade. Both true state dependence and unobserved heterogeneity contribute considerably to trade persistence and taking this persistence into account matters significantly in identifying the effects of trade policies on the extensive margin.},

  abstract  = {Usually, in monocentric city models, the spatial patterns of segregated ethnic groups are assumed to be ring-shaped, whereas in the 1930ies Hoyt showed that empirically wedge-shaped areas predominate. In contrast to Rose-Ackerman.s discussion of the in.uence within a ring-shaped pattern which the aversion which different households in the context of racism have, Yinger showed that, depending on the population mix, a wedge-shaped pattern may arise if it is border length which causes the spatial pattern. In this contribution, a simulation based on a monocentric city model with two or more different household groups is used to derive spatial patterns. Wedge-shaped segregation is shown to be the result of positive externalities among similar households. Differences between households only lead to ring-shaped patterns if the e\iect of a city center on spatial structure dominates neighborhood e\iects. If more than two groups of households are being considered, mixed patterns of concentric and wedge-shaped areas arise.},

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.},
