We design and implement a randomized field experiment in a large mandatory economics course with blended learning elements. The low-cost treatment induces students to use the online learning system more often, more intensively, and to begin earlier with exam preparation. Treated students perform better in the course than the control group: they are 18.8\% (0.20 SD) more likely to pass the exam and earn 6.7\% (0.19 SD) more points on the exam. There is no evidence that treated students spend significantly more time, rather they tend to shift to more productive learning methods. The heterogeneity analysis suggests that higher treatment effects are associated with higher levels of behavioral bias but also with poor early course behavior.}, language = {en} } @techreport{AmorosoHerrmannKritikos2023, type = {Working Paper}, author = {Amoroso, Sara and Herrmann, Benedikt and Kritikos, Alexander}, title = {The Role of Regulation and Regional Government Quality for High Growth Firms}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {71}, issn = {2628-653X}, doi = {10.25932/publishup-61277}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-612771}, pages = {32}, year = {2023}, abstract = {High growth firms (HGFs) are important for job creation and considered to be precursors of economic growth. We investigate how formal institutions, like product- and labor-market regulations, as well as the quality of regional governments that implement these regulations, affect HGF development across European regions. Using data from Eurostat, OECD, WEF, and Gothenburg University, we show that both regulatory stringency and the quality of the regional government influence the regional shares of HGFs. More importantly, we find that the effect of labor- and product-market regulations ultimately depends on the quality of regional governments: in regions with high quality of government, the share of HGFs is neither affected by the level of product market regulation, nor by more or less flexibility in hiring and firing practices. Our findings contribute to the debate on the effects of regulations by showing that regulations are not, per se, "good, bad, and ugly", rather their impact depends on the efficiency of regional governments. Our paper offers important building blocks to develop tailored policy measures that may influence the development of HGFs in a region.}, 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. All effects are robust to the inclusion of a large battery of covariates that are proven to be important determinants of entrepreneurial performance.}, language = {en} } @techreport{KalkuhlFranksGruneretal.2023, type = {Working Paper}, author = {Kalkuhl, Matthias and Franks, Max and Gruner, Friedemann and Lessmann, Kai and Edenhofer, Ottmar}, title = {Pigou's Advice and Sisyphus' Warning}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {62}, issn = {2628-653X}, doi = {10.25932/publishup-57588}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-575882}, pages = {66}, year = {2023}, abstract = {Carbon dioxide removal from the atmosphere is becoming an important option to achieve net zero climate targets. This paper develops a welfare and public economics perspective on optimal policies for carbon removal and storage in non-permanent sinks like forests, soil, oceans, wood products or chemical products. We derive a new metric for the valuation of non-permanent carbon storage, the social cost of carbon removal (SCC-R), which embeds also the conventional social cost of carbon emissions. We show that the contribution of CDR is to create new carbon sinks that should be used to reduce transition costs, even if the stored carbon is released to the atmosphere eventually. 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. Finally, we characterize three different policy regimes that ensure an optimal deployment of carbon removal: downstream carbon pricing, upstream carbon pricing, and carbon storage pricing. The policy regimes differ in their informational and institutional requirements regarding monitoring, liability and financing.}, language = {en} } @techreport{CaliendoTuebbicke2021, type = {Working Paper}, author = {Caliendo, Marco and T{\"u}bbicke, Stefan}, title = {Design and Effectiveness of Start-Up Subsidies}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {30}, issn = {2628-653X}, doi = {10.25932/publishup-50005}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-500056}, pages = {20}, year = {2021}, abstract = {While a growing body of literature finds positive impacts of Start-Up Subsidies (SUS) on labor market outcomes of participants, little is known about how the design of these programs shapes their effectiveness and hence how to improve policy. 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{BruttelBulutayCornandetal.2022, type = {Working Paper}, author = {Bruttel, Lisa Verena and Bulutay, Muhammed and Cornand, Camille and Heinemann, Frank and Zylbersztejn, Adam}, title = {Measuring strategic-uncertainty attitudes}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {54}, issn = {2628-653X}, doi = {10.25932/publishup-56234}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-562340}, pages = {40}, year = {2022}, abstract = {Strategic uncertainty is the uncertainty that players face with respect to the purposeful behavior of other players in an interactive decision situation.

We vary the source of uncertainty (whether strategic or not) across conditions in a ceteris paribus manner. We elicit certainty equivalents of participating in two strategic 2x2 games (a stag-hunt and a market-entry game) as well as certainty equivalents of related lotteries that yield the same possible payoffs with exogenously given probabilities (risk) and lotteries with unknown probabilities (ambiguity). We provide a structural model of uncertainty attitudes that allows us to measure a preference for or an aversion against the source of uncertainty, as well as optimism or pessimism regarding the desired outcome. We document systematic attitudes towards strategic uncertainty that vary across contexts. Under strategic complementarity [substitutability], the majority of participants tend to be pessimistic [optimistic] regarding the desired outcome.

Two main factors of leadership impact are the ability to induce high contributions by all group members and the (expected) fair use of power. Participants in our experiment decide about contributions to a public good. After all contributions are made, the leader can choose how much of the joint earnings to assign to herself; the remainder is distributed equally among the followers. Using machine learning techniques, we study whether the content of initial open statements by the group members predicts their behavior as a leader and whether groups are able to identify such clues and endogenously appoint a "good" leader to solve the dilemma. We find that leaders who promise fairness are more likely to behave fairly, and that followers appoint as leaders those who write more explicitly about fairness and efficiency. However, in their contribution decision, followers focus on the leader's first-move contribution and place less importance on the content of the leader's statements.}, 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.

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.

Many governments introduced programs to financially support the self-employed during the pandemic, including Germany. The German Ministry for Economic Affairs announced a €50bn emergency-aid program in March 2020, offering one-off lump-sum payments of up to €15,000 to those facing substantial revenue declines. 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. We investigate whether the program affected the confidence of the self-employed to survive the crisis using real-time online-survey data comprising more than 20,000 observations. We employ propensity score matching, making use of a rich set of variables that influence the subjective survival probability as main outcome measure. We observe that this program had significant effects, with the subjective survival probability of the self- employed being moderately increased. We reveal important effect heterogeneities with respect to education, industries, and speed of payment. Notably, positive effects only occur among those self-employed whose application was processed quickly. This suggests stress-induced waiting costs due to the uncertainty associated with the administrative processing and the overall pandemic situation.
