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.}, language = {en} } @techreport{Sanner2001, type = {Working Paper}, author = {Sanner, Helge}, title = {Bargaining structure and regional unemployment insurance}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-13747}, year = {2001}, abstract = {This study examines how the size of trade unions relative to the la- bor force impacts on the desirability of different organizational forms of self-financing unemployment insurance (UI) for workers, firms, and with reference to an efficiency criterion.

In 1924, as a reaction to the establishment of judicial institutions in the Treaty of Versailles, the German Reich founded the Kaiser Wilhelm Institute for Comparative Public Law and International Law. Director Viktor Bruns institutionalized the practice-oriented method to advance the idea of international law as a legal order as well as to safeguard the interests of the Weimar government before the various courts. Under National Socialism, members of the Institute provided legal justifications for Hitler's increasingly radical foreign policy. At the same time, some of them did not engage with v{\"o}lkisch-racist theories, but systematized the existing ius in bello. After 1945, Hermann Mosler, as director of the renamed Max Planck Institute, took the view that the practice-oriented approach was not as discredited as the more theoretical approach of v{\"o}lkisch international law. Furthermore, he regarded the method as a promising vehicle to support the policy of Westintegration of Konrad Adenauer.

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.

Furthermore, after 1945 Soviet thinkers of the Khrushchev era used jus cogens to criticize Western economic and military integration, while newly independent states regarded the concept as a promising vehicle for distancing themselves from traditional Western international legal notions in the era of decolonization.

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.}, language = {en} } @techreport{CaliendoWittbrodt2021, type = {Working Paper}, author = {Caliendo, Marco and Wittbrodt, Linda}, title = {Did the Minimum Wage Reduce the Gender Wage Gap in Germany?}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {40}, issn = {2628-653X}, doi = {10.25932/publishup-53046}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-530464}, pages = {26}, year = {2021}, abstract = {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.

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.

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.

In a difference-in-differences design that we validate with regression discontinuity tests and a novel instrumental variables approach, we find that unionization leads to a leftward shift of campaign contributions. Unionization increases the support for Democrats relative to Republicans not only among workers but also among managers, which speaks against an increase in political cleavages between the two groups.

Results are robust to how the wage is measured, as well as to various further robustness checks. More importantly, we find substantial differences between industries. While, for instance, in the manufacturing sector, the gender of the owner plays no role for the gender pay gap, in several service sector industries, like ICT or business services, no or a negligible gender pay gap can be found, but only when firms are led by female business owners. Businesses in male ownership maintain a gender pay gap of around 10 percent also in the latter industries. With increasing firm size, the influence of the gender of the owner, however, fades.

It is supposed to increase fertility, promote children's development and enhance mothers' labor market attachment. In this paper, we analyze the causal effect of one of the largest expansions of subsidized childcare for children up to three years among industrialized countries on the employment of mothers in Germany. Identification is based on spatial and temporal variation in the expansion of publicly subsidized childcare triggered by two comprehensive childcare policy reforms. The empirical analysis is based on the German Microcensus that is matched to county level data on childcare availability. Based on our preferred specification which includes time and county fixed effects we find that an increase in childcare slots by one percentage point increases mothers' labor market participation rate by 0.2 percentage points. The overall increase in employment is explained by the rise in part-time employment with relatively long hours (20-35 hours per week). We do not find a change in full-time employment or lower part-time employment that is causally related to the childcare expansion. The effect is almost entirely driven by mothers with medium-level qualifications.

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.

Notably, positive effects only occur among those self-employed whose application was processed quickly.

Introducing extra clean-up certificates into an existing ETS reduces near-term carbon prices and mitigation efforts. In contrast, substituting ETS allowances with clean-up certificates reduces cumulative emissions without depressing carbon prices or mitigation in the near term. We calibrate our model to the EU ETS and identify reforms where simultaneously (i) ambition levels rise, (ii) climate damages fall, (iii) revenues from carbon prices rise and (iv) carbon prices and aggregate mitigation cost fall. For reducing climate damages, roughly half of the issued clean-up certificates should replace conventional ETS allowances.

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.

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.}, language = {en} } @techreport{Tuebbicke2020, type = {Working Paper}, author = {T{\"u}bbicke, Stefan}, title = {Entropy Balancing for Continuous Treatments}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {21}, issn = {2628-653X}, doi = {10.25932/publishup-47895}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-478950}, pages = {32}, year = {2020}, abstract = {Interest in evaluating the effects of continuous treatments has been on the rise recently. To facilitate the estimation of causal effects in this setting, the present paper introduces entropy balancing for continuous treatments (EBCT) by extending the original entropy balancing methodology of Hainm{\"u}ller (2012). In order to estimate balancing weights, the proposed approach solves a globally convex constrained optimization problem, allowing for much more computationally efficient implementation compared to other available methods. EBCT weights reliably eradicate Pearson correlations between covariates and the continuous treatment variable. This is the case even when other methods based on the generalized propensity score tend to yield insufficient balance due to strong selection into different treatment intensities. Moreover, the optimization procedure is more successful in avoiding extreme weights attached to a single unit. Extensive Monte-Carlo simulations show that treatment effect estimates using EBCT display similar or lower bias and uniformly lower root mean squared error. These properties make EBCT an attractive method for the evaluation of continuous treatments.

Yet, attendant accounts of how such changes may and already do restructure global legal order remain relatively underdeveloped. An observed rise in the international rule of law during immediate post-Cold War years has now been disrupted by a confluence of regional shifts in geopolitical power and contestation of law's normative foundations by newly empowered states. In these circumstances, advocates for stability and continuity in variations of the "liberal international order" or "rules-based order" have sought to defend the authority and resilience of universally defined international legal norms against various regional challenges to the boundary between law and politics. Yet, as both global power and universal conceptions of law fragment, so too will the presumed equilibrium between international law's political and normative foundations. Signs of fragmentation are now conspicuously playing out in East and Southeast Asia, where the relative rise of China is amplified by alternative Chinese conceptions of foundations and purposes of global legal order. This working paper introduces the concept of "geolegal power" to describe the competitive logic of a territorially bounded leading state restructuring interpretation and development of legal rules and institutions, which is emerging more explicitly within regional subsystems. Fragmentation of the international rule of law by a rising Chinese "geolegal order" is demonstrated by contested maritime rules in three key areas: freedom of navigation; third-party and judicial settlement; and, territorial claims under UNCLOS. Evidence that China is carving out an effective subsystem of rules designated as "law" in the most consequential of security and geopolitical domains poses a critical challenge to the structure of a unified and universal system of international law. Legal scholars and practitioners must better grasp reconfiguring foundations of international law in order to address rising orders of "geolegal power", in which the regional meaning and operation of law is no longer reconcilable within the terms of an "international" rule of law.}, language = {en} } @techreport{Andres2024, type = {Working Paper}, author = {Andres, Maximilian}, title = {Equilibrium selection in infinitely repeated games with communication}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {75}, issn = {2628-653X}, doi = {10.25932/publishup-63180}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-631800}, pages = {38}, year = {2024}, abstract = {The present paper proposes a novel approach for equilibrium selection in the infinitely repeated prisoner's dilemma where players can communicate before choosing their strategies.

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.

Diese Frage k{\"o}nnte in eine weitere {\"u}bertragen werden: Gibt es eine - m{\"o}glicherweise von Christaller abweichende - optimale St{\"a}dtehierarchie? Die Antworten auf die Fragen k{\"o}nnen von verschiedenen Disziplinen gegeben werden, sowohl die Stadtsoziologie als auch die Stadtplanung kann Beitr{\"a}ge liefern; in den nachfolgenden {\"U}berlegungen sollen wirtschaftliche Gesichtspunkte im Zentrum einer raumwirtschaftlichen und stadt{\"o}konomischen Analyse stehen.}, language = {de} } @techreport{LudolphŠedova2021, type = {Working Paper}, author = {Ludolph, Lars and Šedov{\´a}, Barbora}, title = {Global food prices, local weather and migration in Sub-Saharan Africa}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {26}, issn = {2628-653X}, doi = {10.25932/publishup-49494}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-494946}, pages = {53}, year = {2021}, abstract = {In this paper, we study the effect of exogenous global crop price changes on migration from agricultural and non-agricultural households in Sub-Saharan Africa. We show that, similar to the effect of positive local weather shocks, the effect of a locally-relevant global crop price increase on household out-migration depends on the initial household wealth. Higher international producer prices relax the budget constraint of poor agricultural households and facilitate migration. The order of magnitude of a standardized price effect is approx. one third of the standardized effect of a local weather shock. Unlike positive weather shocks, which mostly facilitate internal rural-urban migration, positive income shocks through rising producer prices only increase migration to neighboring African countries, likely due to the simultaneous decrease in real income in nearby urban areas. Finally, we show that while higher producer prices induce conflict, conflict does not play a role for the household decision to send a member as a labor migrant.}, language = {en} } @techreport{Eickhof2003, type = {Working Paper}, author = {Eickhof, Norbert}, title = {Globalisierung, institutioneller Wettbewerb und nationale Wirtschaftspolitik}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-13839}, year = {2003}, abstract = {Inhalt 1 Globalisierung und Wettbewerb 1.1 Einzelne Aspekte 1.2 Unterschiedliche Bewertungen 2 Das MacDougall-Kemp-Modelldes institutionellen Wettbewerbs 2.1 Modellpr{\"a}missen und -implikationen 2.2 Empirische Evidenz 3 Untersuchung weiterer Politikbereiche 3.1 Sozial- und Umweltpolitik 3.2 Wettbewerbspolitik 4 M{\"a}ngel der betrachteten Ans{\"a}tze 4.1 Transaktionskosten von Individuen und Unternehmen 4.2 Verhaltensweisen privater und politischer Akteure 5 Wirtschaftspolitische Konsequenzen}, language = {de} }
