Capital Requirements, Market Structure, and Heterogeneous Banks

IWH Discussion Papers,
No. 15,

Abstract
Bank regulators interfere with the efficient allocation of resources for the sake of financial stability. Based on this trade-off, I compare how different capital requirements affect default probabilities and the allocation of market shares across heterogeneous banks. In the model, banks‘ productivity determines their optimal strategy in oligopolistic markets. Higher productivity gives banks higher profit margins that lower their default risk. Hence, capital requirements indirectly aiming at high-productivity banks are less effective. They also bear a distortionary cost: Because incumbents increase interest rates, new entrants with low productivity are attracted and thus average productivity in the banking market decreases.

Investment, output gap, and public finances in the medium term: Implications of the Second Supplementary Budget 2021
With the Second Supplementary Budget 2021, the German government plans to allocate a reserve of 60 billion euros to the Energy and Climate Fund. This additional spending is also meant to reduce the macroeconomic follow-up costs of the pandemic. According to the IWH’s medium-term projection, the expenditure is expected to increase output by about 0.5% at the peak of its impact in 2024. “While this macroeconomic effect is welcome, the additional investment will by no means compensate for the lack of investment activity since the beginning of the pandemic,” says Oliver Holtemöller, head of the Department Macroeconomics and vice president at Halle Institute for Economic Research (IWH). Moreover, the supplementary budget is likely to reduce confidence in the reliability of the debt brake.

Spillover Effects in Empirical Corporate Finance
Tobias Berg, Markus Reisinger, Daniel Streitz
Journal of Financial Economics,
No. 3,
2021
Abstract
Despite their importance, the discussion of spillover effects in empirical research often misses the rigor dedicated to endogeneity concerns. We analyze a broad set of workhorse models of firm interactions and show that spillovers naturally arise in many corporate finance settings. This has important implications for the estimation of treatment effects: i) even with random treatment, spillovers lead to a complicated bias, ii) fixed effects can exacerbate the spillover-induced bias. We propose simple diagnostic tools for empirical researchers and illustrate our guidance in an application.

Worker Participation in Decision-making, Worker Sorting, and Firm Performance
Steffen Müller, Georg Neuschäffer
Industrial Relations,
No. 4,
2021
Abstract
Worker participation in decision-making is often associated with high-wage and high-productivity firm strategies. Using linked employer–employee data for Germany and worker fixed effects from a two-way fixed-effects model of wages capturing observed and unobserved worker quality, we find that plants with formal worker participation via works councils indeed employ higher quality workers. We show that worker quality is already higher in plants before council introduction and further increases after the introduction. Importantly, we corroborate previous studies by showing positive productivity and profitability effects even after taking into account worker sorting.

Consumer Defaults and Social Capital
Brian Clark, Iftekhar Hasan, Helen Lai, Feng Li, Akhtar Siddique
Journal of Financial Stability,

2021
Abstract
Using account level data from a credit bureau, we study the role that social capital plays in consumer default decisions. We find that borrowers in communities with greater social capital are significantly less likely to default on loans, even after adjusting for different levels of income and other characteristics such as credit scores. The results are strongest for potentially strategic defaults on mortgages; a one standard deviation increase in social capital reduces such defaults by 12.4 %. These results can be generalized to any mortgage default. Our results also indicate that the effect of social capital is most prominent among more creditworthy borrowers, suggesting that when given a choice, the social cost of defaulting is an important factor affecting default decisions. We find a similar impact of social capital on consumer defaults in other datasets with more detailed information on borrowers as well. Our results are robust to modeling and methodology choices, as well as controlling for other drivers of default such as wealth, income and amenities from homeownership. Our results suggest that increasing social capital via measures to build community cohesion such as promotion of owner-occupied home ownership may be one avenue to deter consumer default.
