Financial System Adaptability and Resilience
Financial systems differ across countries and tend to evolve slowly over time. Their structure is typically stable, but their resilience is often tested. A well-functioning financial system is vital for economic development, as it ensures that capital flows to the most productive and valuable investment opportunities. However, systemic vulnerabilities can have far-reaching consequences. For example, the 2007–08 global financial crisis emerged from within the financial sector itself when complex financial products fuelled a credit bubble in the U.S. housing market, threatening global economic stability when the bubble burst. That event led to extensive policy and regulatory reforms to strengthen financial system resilience.
Financial systems continue to face significant challenges. External shocks like the COVID-19 pandemic, the climate crisis, the green economic transition, and the energy crisis driven by geopolitical conflict all underscore the importance of financial systems that can absorb shocks and adapt to changing economic conditions. Motivated by these pressing issues, we investigate how financial systems respond to crises, which institutions and policies improve resilience, and the role of finance systems' setup in broader economic transformations. We use diverse data sources, including bank and firm-level data, regulatory reports, and house price and election data, to inform evidence-based policy.

OVERHANG: Debt overhang and green investments - the role of banks in climate-friendly management of emission-intensive fixed assets
The collaborative project “Debt Overhang and Green Investments” (OVERHANG) aims to investigate the role of banks in the climate-friendly management of emission-intensive fixed assets. This will identify policy-relevant insights on financial regulation, government-controlled lending and financial stability, as well as raise awareness among indebted stakeholders.

Relationship Lenders and Unorthodox Monetary Policy: Investment, Employment, and Resource Reallocation Effects
Leibniz Association
We combine a number of unique and proprietary data sources to measure the impact of relationship lenders and unconventional monetary policy during and after the European sovereign debt crisis on the real economy. Establishing systematic links between different research data centers (Forschungsdatenzentren, FDZ) and central banks with detailed micro-level information on both financial and real activity is the stand-alone proposition of our proposal. The main objective is to permit the identification of causal effects, or their absence, regarding which policies were conducive to mitigate financial shocks and stimulate real economic activities, such as employment, investment, or the closure of plants.

The State Expropriation Risk and the Pricing of Foreign Earnings
in: Journal of International Accounting Research, Vol. 20 (2), 2021
Abstract
We examine the pricing of U.S. multinational firms' foreign earnings in regard to their risk of expropriation and unfair treatment by the governments of the countries in which their international subsidiaries are located. Using 8,891 firm-years observations during the 2001–2013 period, we find that the value relevance of foreign earnings increases with the improvement of the protection from state expropriation risk in the subsidiary host-countries. Our results are not driven by the earnings management practice, investor distraction, country informativeness, and political and trade relationship of a foreign country with the U.S. Furthermore, our results are robust to the confounding effects of country factors, measurement error in the variable of the risk of expropriation, the influence of private contracting institutions, and endogeneity in the decision of the location of subsidiaries.
Finance-Growth Nexus and Banking Efficiency: The Impact of Microfinance Institutions
in: Journal of Economics and Business, Vol. 114 (March-April), 2021
Abstract
This paper investigates the relative importance of microfinance institutions (MFIs) at both the macro (financial development, economic growth, income inequality, and poverty) and micro levels (efficiency of traditional commercial banks). We observe a significant impact on most of the fronts. MFIs’ participation increases overall savings (total bank deposits) and credit allocation (loans to private sector) in the economy. Their involvement enhances economic welfare by reducing income inequality and poverty. Additionally, their active presence helps to discipline the traditional commercial banks by subjecting them to more competition triggering higher efficiency.
The Real Impact of Ratings-based Capital Rules on the Finance-Growth Nexus
in: International Review of Financial Analysis, Vol. 73 (January), 2021
Abstract
We investigate whether ratings-based capital regulation has affected the finance-growth nexus via a foreign credit channel. Using quarterly data on short to medium term real GDP growth and cross-border bank lending flows from G-10 countries to 67 recipient countries, we find that since the implementation of Basel 2 capital rules, risk weight reductions mapped to sovereign credit rating upgrades have stimulated short-term economic growth in investment grade recipients but hampered growth in non-investment grade recipients. The impact of these rating upgrades is strongest in the first year and then reverses from the third year and onwards. On the other hand, there is a consistent and lasting negative impact of risk weight increases due to rating downgrades across all recipient countries. The adverse effects of ratings-based capital regulation on foreign bank credit supply and economic growth are compounded in countries with more corruption and less competitive banking sectors and are attenuated with greater political stability.
Transactional and Relational Approaches to Political Connections and the Cost of Debt
in: Journal of Corporate Finance, Vol. 65 (December), 2020
Abstract
This paper examines the economic effects of a firm's approach to developing and maintaining political connections. Specifically, we investigate whether lenders favor transactional connection as opposed to relational connection. By tracing firms in a politically volatile emerging democracy in Indonesia, we find that firms following a transactional political connection strategy experience a relatively lower cost of debt than those with a relational strategy. The effect is more pronounced for firms facing high financial distress. The finding is robust to cost of bank loans and a variety of regression methods. Overall, the evidence suggests that in times of frequently changing political regimes, firms benefit from a transactional relationship with politicians as it enables to update connection with the government in power. Relational connection is valuable for a firm only when the political regime connected with it gains power.
Borrowers Under Water! Rare Disasters, Regional Banks, and Recovery Lending
in: Journal of Financial Intermediation, Vol. 43 (July), 2020
Abstract
We show that local banks provide corporate recovery lending to firms affected by adverse regional macro shocks. Banks that reside in counties unaffected by the natural disaster that we specify as macro shock increase lending to firms inside affected counties by 3%. Firms domiciled in flooded counties, in turn, increase corporate borrowing by 16% if they are connected to banks in unaffected counties. We find no indication that recovery lending entails excessive risk-taking or rent-seeking. However, within the group of shock-exposed banks, those without access to geographically more diversified interbank markets exhibit more credit risk and less equity capital.

Ecological Preferences and the carbon Intensity of Corporate Investment
in: IWH Discussion Papers, No. 2, 2025
Abstract
Lowering carbon intensity in manufacturing is necessary to transform current production technologies. We test if local agents’ preferences, revealed by vote shares for the Green party during local elections in Germany, relate to the carbon intensity of investments in production technologies. Our sample comprises all investment choices made by manufacturing establishments from 2005-2017. Our results suggest that ecological preferences correlate with significantly fewer carbon-intensive investment projects while investments stimulating growth and reducing carbon emissions increase by 14 percentage points. Both results are more distinct in federal states where the Green Party enjoys political power and local ecological preferences are high.
Green Investing, Information Asymmetry, and Capital Structure
in: IWH Discussion Papers, No. 20, 2023
Abstract
We investigate how optimal attention allocation of green-motivated investors changes information asymmetry in financial markets and thus affects firms‘ financing costs. To guide our empirical analysis, we propose a model where investors with heterogeneous green preferences endogenously allocate limited attention to learn market-level or firm-specific fundamental shocks. We find that a higher fraction of green investors in the market leads to higher aggregate attention to green firms. This reduces the information asymmetry of green firms, leading to higher price informativeness and lower leverage. Moreover, the information asymmetry of brown firms and the market increases with the share of green investors. Therefore, greater green attention is associated with less market efficiency. We provide empirical evidence to support our model predictions using U.S. data. Our paper shows how the growing demand for sustainable investing shifts investors‘ attention and benefits eco-friendly firms.
Long-run Competitive Spillovers of the Credit Crunch
in: IWH Discussion Papers, No. 10, 2023
Abstract
Competition in the U.S. appears to have declined. One contributing factor may have been heterogeneity in the availability of credit during the financial crisis. I examine the impact of product market peer credit constraints on long-run competitive outcomes and behavior among non-financial firms. I use measures of lender exposure to the financial crisis to create a plausibly exogenous instrument for product market credit availability. I find that credit constraints of product market peers positively predict growth in sales, market share, profitability, and markups. This is consistent with the notion that firms gained at the expense of their credit constrained peers. The relationship is robust to accounting for other sources of inter-firm spillovers, namely credit access of technology network and supply chain peers. Further, I find evidence of strategic investment, i.e. the idea that firms increase investment in response to peer credit constraints to commit to deter entry mobility. This behavior may explain why temporary heterogeneity in the availability of credit appears to have resulted in a persistent redistribution of output across firms.
Banking Market Deregulation and Mortality Inequality
in: Bank of Finland Research Discussion Papers, No. 14, 2022
Abstract
This paper shows that local banking market conditions affect mortality rates in the United States. Exploiting the staggered relaxation of branching restrictions in the 1990s across states, we find that banking deregulation decreases local mortality rates. This effect is driven by a decrease in the mortality rate of black residents, implying a decrease in the black-white mortality gap. We further analyze the role of mortgage markets as a transmitter between banking deregulation and mortality and show that households' easier access to finance explains mortality dynamics. We do not find any evidence that our results can be explained by improved labor outcomes.
Capital Requirements, Market Structure, and Heterogeneous Banks
in: IWH Discussion Papers, No. 15, 2022
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.
