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.}, language = {en} } @techreport{Gulati2020, type = {Working Paper}, author = {Gulati, Rishi}, title = {Judicial Independence at International Courts and Tribunals}, series = {KFG Working Paper Series}, journal = {KFG Working Paper Series}, number = {41}, doi = {10.25932/publishup-47599}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-475997}, pages = {32}, year = {2020}, abstract = {The guarantee of judicial independence is undoubtedly one of the most important institutional design features of international courts and tribunals. An independence deficit can adversely impact a court's authority, create a crisis of legitimacy, and undermine the very effectiveness of an international court or tribunal. It can hardly be denied that for an international court to be considered legitimate, a basic degree of independence is a must. An independent judiciary is a precondition to the fair and just resolution of legal disputes. In the context of interstate dispute settlement where the jurisdiction of courts is based on the principle of consent, in the absence of a basic degree of judicial independence, states may not be willing to submit to the jurisdiction of international courts. Comparing and contrasting the International Court of Justice and the Appellate Body of the World Trade Organisation, I assess whether those international judicial mechanisms possess the basic degree of independence required for a court to be able to maintain its credibility so that it can continue to perform its core function of adjudicating interstate disputes. With both those interstate adjudicative bodies constituting the two leading international courts in terms of participation and the sheer number of cases decided, much may be learned from comparing them. I argue there is a case for bolstering the independence of the ICJ; and without immediate reforms to the Appellate Body's institutional design, its recent demise may become permanent. I conclude that if a basic degree of judicial independence cannot be guaranteed, it is preferable to let a court vanish for a while than to maintain a significantly deficient one.}, language = {en} } @techreport{BarkholdtReiners2019, type = {Working Paper}, author = {Barkholdt, Janina and Reiners, Nina}, title = {Pronouncements of Expert Treaty Bodies}, series = {KFG Working Paper Series}, journal = {KFG Working Paper Series}, number = {40}, doi = {10.25932/publishup-47588}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-475886}, pages = {26}, year = {2019}, abstract = {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.}, language = {en} } @techreport{BruttelGuethNithammeretal.2020, type = {Working Paper}, author = {Bruttel, Lisa Verena and G{\"u}th, Werner and Nithammer, Juri and Orland, Andreas}, title = {Inefficient Cooperation under Stochastic and Strategic Uncertainty}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {20}, issn = {2628-653X}, doi = {10.25932/publishup-47550}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-475500}, year = {2020}, abstract = {Stochastic uncertainty can cause difficult coordination problems that may hinder mutually beneficial cooperation. 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).}, language = {en} } @techreport{AndresBruttelFriedrichsen2020, type = {Working Paper}, author = {Andres, Maximilian and Bruttel, Lisa Verena and Friedrichsen, Jana}, title = {Choosing between explicit cartel formation and tacit collusion - An experiment}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {19}, issn = {2628-653X}, doi = {10.25932/publishup-47388}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-473885}, pages = {55}, year = {2020}, abstract = {Numerous studies investigate which sanctioning institutions prevent cartel formation but little is known as to how these sanctions work. 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.}, language = {en} } @techreport{CaliendoHennecke2020, type = {Working Paper}, author = {Caliendo, Marco and Hennecke, Juliane}, title = {Drinking is Different!}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {18}, issn = {2628-653X}, doi = {10.25932/publishup-46979}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-469790}, year = {2020}, abstract = {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.

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.}, language = {en} } @techreport{AharonBrillFonsecaetal.2020, type = {Working Paper}, author = {Aharon, Itzik and Brill, Antonia and Fonseca, Philip and Vandchali, Azin Alizadeh and Wendel, Nina}, title = {The Protection of Women Human Rights Defenders and their Collective Actions}, series = {Staat, Recht und Politik - Forschungs- und Diskussionspapiere}, journal = {Staat, Recht und Politik - Forschungs- und Diskussionspapiere}, number = {10}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, doi = {10.25932/publishup-44427}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-444278}, pages = {12}, year = {2020}, 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.

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.}, language = {en} } @techreport{GallegoGranadosWrohlich2020, type = {Working Paper}, author = {Gallego Granados, Patricia and Wrohlich, Katharina}, title = {Selection into Employment and the Gender Wage Gap across the Distribution and Over Time}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {15}, issn = {2628-653X}, doi = {10.25932/publishup-44169}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-441691}, year = {2020}, abstract = {Using quantile regression methods, this paper analyses the gender wage gap across the wage distribution and over time (1990-2014), while controlling for changing sample selection 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.}, language = {en} }
