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.

How Do Banks React to Catastrophic Events? Evidence from Hurricane Katrina
in: Review of Finance, Vol. 23 (1), 2019
Abstract
This paper explores how banks react to an exogenous shock caused by Hurricane Katrina in 2005, and how the structure of the banking system affects economic development following the shock. Independent banks based in the disaster areas increase their risk-based capital ratios after the hurricane, while those that are part of a bank holding company on average do not. The effect on independent banks mainly comes from the subgroup of highly capitalized banks. These independent and highly capitalized banks increase their holdings in government securities and reduce their total loan exposures to non-financial firms, while also increasing new lending to these firms. With regard to local economic development, affected counties with a relatively large share of independent banks and relatively high average bank capital ratios show higher economic growth than other affected counties following the catastrophic event.
Senior Debt and Market Discipline: Evidence from Bank-to-bank Loans
in: Journal of Banking and Finance, Vol. 98, 2019
Abstract
We empirically investigate whether taking senior bank loans would enhance market discipline and control risk-taking among borrowing banks. Controlling for endogeneity concern arising from borrowing bank self-select into taking senior bank debt, we document that both the spreads and covenants in loan contracts are sensitive to bank risk variables. Our analysis also reveals that borrowing banks reduce their risk exposure after their first issuance of senior bank debt. We also find that lending banks significantly increase their collaboration with borrowing banks and increase their presence in the home markets of borrowing banks.
Accounting Quality in Banking: The Role of Regulatory Interventions
in: Journal of Banking and Finance, Vol. 97, 2018
Abstract
Using the full sample of U.S. banks and hand-collected data on enforcement actions over 2000–2014, we analyze the role of these interventions in promoting several aspects of accounting quality. We find that enforcement actions issued for both risk-related and accounting-related reasons lead to significant improvements in accounting quality. This improvement is consistently found for earnings smoothing, big-bath accounting, timely recognition of future loan losses, the association of loan loss provisions with future loan charge offs, loss avoidance, and cash flow predictability and earnings persistence. Most of the effects are somewhat more potent in the crisis period and survive in several sensitivity tests. Our findings highlight the imperative role of regulatory interventions in promoting bank accounting quality.
SMEs and Access to Bank Credit: Evidence on the Regional Propagation of the Financial Crisis in the UK
in: Journal of Financial Stability, Vol. 38, 2018
Abstract
We study the sensitivity of banks’ credit supply to small and medium size enterprises (SMEs) in the UK with respect to the banks’ financial condition before and during the financial crisis. Employing unique data on the geographical location of all bank branches in the UK, we connect firms’ access to bank credit to the financial condition (i.e., bank health and the use of core deposits) of all bank branches in the vicinity of the firm for the period 2004–2011. Before the crisis, banks’ local financial conditions did not influence credit availability irrespective of the functional distance (i.e., the distance between bank branch and bank headquarters). However, during the crisis, we find that SMEs with banks within their vicinity that have stronger financial conditions faced greater credit availability when the functional distance is close. Our results point to a “flight to headquarters” effect during the financial crisis.
Crises and Rescues: Liquidity Transmission Through Global Banks
in: International Journal of Central Banking, Vol. 14 (4), 2018
Abstract
This paper shows that global banks transmit liquidity shocks via their network of foreign affiliates. We use the (unexpected) access of German banks' affiliates located in the United States to the Federal Reserve's Term Auction Facility. We condition on the parent banks' U.S. dollar funding needs in order to examine how affiliates located outside the United States adjusted their balance sheets when the U.S. affiliate of the same parent tapped into TAF liquidity. Our research has three main findings. First, affiliates tied to parents with higher U.S. dollar funding needs expanded their foreign assets during periods of active TAF borrowing. Second, the overall effects are driven by affiliates located in financial centers. Third, U.S.- dollar-denominated lending particularly increased in response to the TAF program.

What Drives Banks‘ Geographic Expansion? The Role of Locally Non-diversifiable Risk
in: IWH Discussion Papers, No. 6, 2019
Abstract
We show that banks that are facing relatively high locally non-diversifiable risks in their home region expand more across states than banks that do not face such risks following branching deregulation in the 1990s and 2000s. These banks with high locally non-diversifiable risks also benefit relatively more from deregulation in terms of higher bank stability. Further, these banks expand more into counties where risks are relatively high and positively correlated with risks in their home region, suggesting that they do not only diversify but also build on their expertise in local risks when they expand into new regions.
Politics, Banks, and Sub-sovereign Debt: Unholy Trinity or Divine Coincidence?
in: Deutsche Bundesbank Discussion Paper, No. 53, 2018
Abstract
We exploit election-driven turnover in State and local governments in Germany to study how banks adjust their securities portfolios in response to the loss of political connections. We find that local savings banks, which are owned by their host county and supervised by local politicians, increase significantly their holdings of home-State sovereign bonds when the local government and the State government are dominated by different political parties. Banks' holdings of other securities, like federal bonds, bonds issued by other States, or stocks, are not affected by election outcomes. We argue that banks use sub-sovereign bond purchases to gain access to politically distant government authorities.
May the Force Be with You: Exit Barriers, Governance Shocks, and Profitability Sclerosis in Banking
in: Deutsche Bundesbank Discussion Paper, No. 49, 2018
Abstract
We test whether limited market discipline imposes exit barriers and poor profitability in banking. We exploit an exogenous shock to the governance of government-owned banks: the unification of counties. County mergers lead to enforced government-owned bank mergers. We compare forced to voluntary bank exits and show that the former cause better bank profitability and efficiency at the expense of riskier financial profiles. Regarding real effects, firms exposed to forced bank mergers borrow more at lower cost, increase investment, and exhibit higher employment. Thus, reduced exit frictions in banking seem to unleash the economic potential of both banks and firms.
Banks Fearing the Drought? Liquidity Hoarding as a Response to Idiosyncratic Interbank Funding Dry-ups
in: IWH Discussion Papers, No. 12, 2018
Abstract
Since the global financial crisis, economic literature has highlighted banks’ inclination to bolster up their liquid asset positions once the aggregate interbank funding market experiences a dry-up. To this regard, we show that liquidity hoarding and its detrimental effects on credit can also be triggered by idiosyncratic, i.e. bankspecific, interbank funding shocks with implications for monetary policy. Combining a unique data set of the Brazilian banking sector with a novel identification strategy enables us to overcome previous limitations for studying this phenomenon as a bankspecific event. This strategy further helps us to analyse how disruptions in the bank headquarters’ interbank market can lead to liquidity and lending adjustments at the regional bank branch level. From the perspective of the policy maker, understanding this market-to-market spillover effect is important as local bank branch markets are characterised by market concentration and relationship lending.
Flooded Through the Back Door: Firm-level Effects of Banks‘ Lending Shifts
in: IWH Discussion Papers, No. 4, 2018
Abstract
I show that natural disasters transmit to firms in non-disaster areas via their banks. This spillover of non-financial shocks through the banking system is stronger for banks with less regulatory capital. Firms connected to a disaster-exposed bank with below median capital reduce their employment by 11% and their fixed assets by 20% compared to firms in the same region without such a bank during the 2013 flooding in Germany. Relationship banking and higher firm capital also mitigate the effects of such negative cross-regional spillovers.
