In a first-best setting, the optimal use of CDR is achieved by a removal subsidy that equals the optimal carbon tax and marginal damages. We derive second-best subsidies for CDR when no global carbon price exists but a national government implements a unilateral climate policy. We find that the optimal carbon tax differs from an optimal CDR subsidy because of carbon leakage, terms-of-trade and fossil resource rent dynamics. First, the optimal removal subsidy tends to be larger than the carbon tax because of lower supply-side leakage on fossil resource markets. Second, terms-of-trade effects exacerbate this wedge for net resource exporters, implying even larger removal subsidies. Third, the optimal removal subsidy may fall below the carbon tax for resource-poor countries when marginal environmental damages are small.}, language = {en} } @techreport{EydamDiluiso2022, type = {Working Paper}, author = {Eydam, Ulrich and Diluiso, Francesca}, title = {How to Redistribute the Revenues from Climate Policy?}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {45}, issn = {2628-653X}, doi = {10.25932/publishup-54896}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-548960}, pages = {32}, year = {2022}, abstract = {In light of climate change mitigation efforts, revenues from climate policies are growing, with no consensus yet on how they should be used. Potential efficiency gains from reducing distortionary taxes and the distributional implications of different revenue recycling schemes are currently debated. To account for households heterogeneity and dynamic trade-offs, we study the macroeconomic and welfare performance of different revenue recycling schemes using an Environmental Two-Agent New-Keynesian model, calibrated on the German economy. We find that, in the long run, welfare gains are higher when revenues are used to reduce distortionary taxes on capital, but this comes at the cost of higher inequality: while all households prefer labor income tax reductions to lump-sum transfers, only financially unconstrained households are better off when reducing taxes on capital income. Interestingly, we find that over the transition period relevant to meet short-medium run climate targets, labor income tax cuts are the most efficient and equitable instrument.}, language = {en} } @techreport{EstrinKhavulKritikosetal.2024, type = {Working Paper}, author = {Estrin, Saul and Khavul, Susanna and Kritikos, Alexander and L{\"o}her, Jonas}, title = {Access to digital finance}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {72}, issn = {2628-653X}, doi = {10.25932/publishup-62326}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-623261}, pages = {27}, year = {2024}, abstract = {Financing entrepreneurship spurs innovation and economic growth. Digital financial platforms that crowdfund equity for entrepreneurs have emerged globally, yet they remain poorly understood. We model equity crowdfunding in terms of the relationship between the number of investors and the amount of money raised per pitch. We examine heterogeneity in the average amount raised per pitch that is associated with differences across three countries and seven platforms. Using a novel dataset of successful fundraising on the most prominent platforms in the UK, Germany, and the USA, we find the underlying relationship between the number of investors and the amount of money raised for entrepreneurs is loglinear, with a coefficient less than one and concave to the origin. We identify significant variation in the average amount invested in each pitch across countries and platforms.

This paper reviews several theoretical models that try to explain this phenomenon. Predominantly, these models claim a link between the poor performance of European labor markets and the high level of market regulation. Commonly referred to as the Eurosclerosis debate, prominent approaches consider insider-outsider relationships, search-models, and the influence of hiring and firing costs on equilibrium employment. The paper presents empirical evidence of each model and studies the relevance of the identified rigidities as a determinant of high unemployment in Europe. Furthermore, a case study analyzes the unemployment problem in Germany and critically discusses new reform efforts.

It thematizes attempts to juridify environmental destruction in international criminal law and examines the Climate Fund Case at the Brazilian Supreme Court.

As experimental variation in program design is unavailable, we exploit the 2011 reform of the current German SUS program for the unemployed which strengthened case-workers' discretionary power, increased entry requirements and reduced monetary support. 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{CaliendoKuennMahlstedt2022, type = {Working Paper}, author = {Caliendo, Marco and K{\"u}nn, Steffen and Mahlstedt, Robert}, title = {The Intended and Unintended Effects of Promoting Labor Market Mobility}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, issn = {2628-653X}, doi = {10.25932/publishup-53522}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-535229}, pages = {49}, year = {2022}, abstract = {Subsidizing the geographical mobility of unemployed workers may improve welfare by relaxing their financial constraints and allowing them to find jobs in more prosperous regions. We exploit regional variation in the promotion of mobility programs along administrative borders of German employment agency districts to investigate the causal effect of offering such financial incentives on the job search behavior and labor market integration of unemployed workers. 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.}, language = {en} } @techreport{CaliendoKritikosStier2022, type = {Working Paper}, author = {Caliendo, Marco and Kritikos, Alexander and Stier, Claudia}, title = {The Influence of Start-up Motivation on Entrepreneurial Performance}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {59}, issn = {2628-653X}, doi = {10.25932/publishup-57115}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-571152}, pages = {43}, year = {2022}, abstract = {Predicting entrepreneurial development based on individual and business-related characteristics is a key objective of entrepreneurship research. In this context, we investigate whether the motives of becoming an entrepreneur influence the subsequent entrepreneurial development. In our analysis, we examine a broad range of business outcomes including survival and income, as well as job creation, expansion and innovation activities for up to 40 months after business formation. 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.

Financial losses are important in explaining these differences.
