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{CaliendoKuennWeissenberger2019, type = {Working Paper}, author = {Caliendo, Marco and K{\"u}nn, Steffen and Weißenberger, Martin}, title = {Catching up or Lagging Behind?}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {12}, issn = {2628-653X}, doi = {10.25932/publishup-43701}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-437012}, year = {2019}, abstract = {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.}, language = {en} } @techreport{AmannRzepka2021, type = {Working Paper}, author = {Amann, Erwin and Rzepka, Sylvi}, title = {The Effect of Goal-Setting Prompts in a Blended Learning Environment}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {25}, issn = {2628-653X}, doi = {10.25932/publishup-49347}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-493476}, pages = {22, vi}, year = {2021}, abstract = {We investigate how inviting students to set task-based goals affects usage of an online learning platform and course performance.

Importantly, CDR does not raise the ambition of optimal temperature levels unless initial atmospheric carbon stocks are excessively high. For high initial atmospheric carbon stocks, CDR allows to reduce the optimal temperature below initial levels.

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.

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.

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.

To this end, we combine county-level data on child care coverage with detailed individual-level information from the German social security records and exploit a set of German reforms leading to a substantial temporal and spatial variation in child care coverage for children under the age of three. We conduct an event study approach that investigates the labor market outcomes of mothers in the years around the birth of their first child. We thereby explore career trajectories, both in terms of quantity and quality of employment. We find that public child care improves maternal labor supply in the years immediately following childbirth. However, the results on quality-related outcomes suggest that the effect of child care provision does not reach far beyond pure employment effects. These results do not change for mothers with different 'career costs of children'.}, language = {en} } @techreport{BorckGohl2021, type = {Working Paper}, author = {Borck, Rainald and Gohl, Niklas}, title = {Gentrification and Affordable Housing Policies}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {39}, issn = {2628-653X}, doi = {10.25932/publishup-52930}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-529300}, pages = {51}, year = {2021}, abstract = {We use a quantitative spatial equilibrium model to evaluate the distributional and welfare impacts of a recent temporary rent control policy in Berlin, Germany. 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.}, 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. While the effect is highest for the low-paid, it also reaches up into higher parts of the wage distribution.}, language = {en} } @techreport{GraeberKritikosSeebauer2021, type = {Working Paper}, author = {Graeber, Daniel and Kritikos, Alexander and Seebauer, Johannes}, title = {COVID-19: a crisis of the female self-employed}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {27}, issn = {2628-653X}, doi = {10.25932/publishup-49810}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-498108}, pages = {72}, year = {2021}, abstract = {We investigate how the economic consequences of the pandemic, and of the government-mandated measures to contain its spread, affect the self-employed - particularly women - in Germany. For our analysis, we use representative, real-time survey data in which respondents were asked about their situation during the COVID-19 pandemic. Our findings indicate that among the self-employed, who generally face a higher likelihood of income losses due to COVID-19 than employees, women are 35\% more likely to experience income losses than their male counterparts. Conversely, we do not find a comparable gender gap among employees. Our results further suggest that the gender gap among the self-employed is largely explained by the fact that women disproportionately work in industries that are more severely affected by the COVID-19 pandemic. Our analysis of potential mechanisms reveals that women are significantly more likely to be impacted by government-imposed restrictions, i.e. the regulation of opening hours. We conclude that future policy measures intending to mitigate the consequences of such shocks should account for this considerable variation in economic hardship.}, language = {en} } @techreport{HaenselFranksKalkuhletal.2021, type = {Working Paper}, author = {H{\"a}nsel, Martin C. and Franks, Max and Kalkuhl, Matthias and Edenhofer, Ottmar}, title = {Optimal carbon taxation and horizontal equity}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {28}, issn = {2628-653X}, doi = {10.25932/publishup-49812}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-498128}, pages = {51}, year = {2021}, abstract = {We develop a model of optimal carbon taxation and redistribution taking into account horizontal equity concerns by considering heterogeneous energy efficiencies. By deriving first- and second-best rules for policy instruments including carbon taxes, transfers and energy subsidies, we then investigate analytically how horizontal equity is considered in the social welfare maximizing tax structure. We calibrate the model to German household data and a 30 percent emission reduction goal. Our results show that energy-intensive households should receive more redistributive resources than energy-efficient households if and only if social inequality aversion is sufficiently high. We further find that redistribution of carbon tax revenue via household-specific transfers is the first-best policy. Equal per-capita transfers do not suffer from informational problems, but increase mitigation costs by around 15 percent compared to the first- best for unity inequality aversion. Adding renewable energy subsidies or non-linear energy subsidies, reduces mitigation costs further without relying on observability of households' energy efficiency.}, language = {en} } @techreport{FelfeKocherRaineretal.2021, type = {Working Paper}, author = {Felfe, Christina and Kocher, Martin and Rainer, Helmut and Saurer, Judith and Siedler, Thomas}, title = {More Opportunity, More Cooperation?}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {32}, issn = {2628-653X}, doi = {10.25932/publishup-50864}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-508643}, pages = {63}, year = {2021}, abstract = {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.}, language = {en} }
