In view of current contestations it asks whether we are observing yet another period of norm change (Wandel) or even a more fundamental transformation of international law - a metamorphosis (Verwandlung). For this purpose it suggests to look into the mechanisms of how norms change from the perspective of legal and political science and also to approximate a reference point where change turns into metamorphosis. It submits that such a point may be reached where specific legally protected values are indeed changing (change of legal values) or where the very idea of protecting certain values through law is renounced (delegalizing of values). The paper discusses the benefits of such an interdisciplinary exchange and tries to identify differences and commonalities among both disciplinary perspectives.}, language = {en} } @techreport{Kulaga2019, type = {Working Paper}, author = {Kulaga, Julian}, title = {A Renaissance of the Doctrine of Rebus Sic Stantibus?}, series = {KFG Working Paper Series}, journal = {KFG Working Paper Series}, number = {32}, doi = {10.25932/publishup-43578}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-435788}, pages = {21}, year = {2019}, abstract = {Once the "popular plaything of Realpolitiker" the doctrine of rebus sic stantibus post the 1969 VCLT is often described as an objective rule by which, on grounds of equity and justice, a fundamental change of circumstances may be invoked as a ground for termination.

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.}, language = {en} } @techreport{CaliendoTuebbicke2019, type = {Working Paper}, author = {Caliendo, Marco and T{\"u}bbicke, Stefan}, title = {Do Start-Up Subsidies for the Unemployed Affect Participants' Well-Being?}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {14}, issn = {2628-653X}, doi = {10.25932/publishup-43746}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-437468}, pages = {47}, year = {2019}, abstract = {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 ("Gr{\"u}ndungszuschuss") 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.}, language = {en} } @techreport{MuellerWrohlich2019, type = {Working Paper}, author = {M{\"u}ller, Kai-Uwe and Wrohlich, Katharina}, title = {Does subsidized care for toddlers increase maternal labor supply?}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {9}, issn = {2628-653X}, doi = {10.25932/publishup-42772}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-427727}, pages = {50}, year = {2019}, abstract = {Expanding public or publicly subsidized childcare has been a top social policy priority in many industrialized countries. 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. Mothers with low education levels do not profit from this reform calling for a stronger policy focus on particularly disadvantaged groups in coming years.}, language = {en} } @techreport{deWet2019, type = {Working Paper}, author = {de Wet, Erika}, title = {Entrenching international values through positive law}, series = {KFG Working Paper Series}, journal = {KFG Working Paper Series}, number = {25}, issn = {2509-3770}, doi = {10.25932/publishup-42385}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-423859}, pages = {19}, year = {2019}, abstract = {Underpinning a legal system with certain values and helping to resolve norm conflicts is in domestic legal systems usually achieved through hierarchical superiority of certain norms of a constitutional nature. 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.}, language = {en} } @techreport{CaliendoGoethnerWeissenberger2019, type = {Working Paper}, author = {Caliendo, Marco and Goethner, Maximilian and Weißenberger, Martin}, title = {Entrepreneurial Persistence Beyond Survival: Measurement and Determinants}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {11}, issn = {2628-653X}, doi = {10.25932/publishup-43456}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-434563}, year = {2019}, abstract = {Entrepreneurial persistence is demonstrated by an entrepreneur's continued positive maintenance of entrepreneurial motivation and constantly-renewed active engagement in a new business venture despite counter forces or enticing alternatives. 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{KauffmannNastansky2019, type = {Working Paper}, author = {Kauffmann, Albrecht and Nastansky, Andreas}, title = {Explorative Analyse der Preise von Einfamilienh{\"a}usern und Eigentumswohnungen in Deutschland}, series = {Statistische Diskussionsbeitr{\"a}ge}, journal = {Statistische Diskussionsbeitr{\"a}ge}, number = {52}, doi = {10.25932/publishup-42926}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-429266}, pages = {47}, year = {2019}, abstract = {Untersucht werden die von BulwienGesa erhobenen und aufbereiteten jahresdurchschnittlichen Wiederverkaufspreise von Eigentumswohnungen und Einfamilienh{\"a}usern in 401 kreisfreien St{\"a}dten und Landkreisen f{\"u}r die Jahre 2004-2017.
