Financial System Adaptability and Resilience
Financial Systems differ between countries. Their configuration is sticky and does not change suddenly. A well-functioning financial system is essential for economic development by efficiently allocating capital to the highest net present value projects.
However, the resilience of financial systems is frequently challenged. For example, the Great Financial Crisis of 2007/08 was a large blow from within the system: New financial instruments fuelled a credit bubble in the United States' housing markets, which almost brought down the global financial system when it eventually burst. The crisis triggered hefty government interventions and regulatory actions to make financial systems more resilient.
More frequently, challenges like the Covid-19 pandemic, the climate crisis and the green transition of economies, and the energy crisis triggered by the war in Ukraine, again highlight the crucial importance of resilient financial systems that adapt themselves and facilitate adequate responses to shocks of the real economy alike.
The research group “Financial System Adaptability and Resilience” investigates three critical aspects of financial system adaptability and resilience. First, it uses the occurrence of major natural disasters in the United States and Germany to analyse the impact of these events on financial systems. Natural disasters are becoming more frequent and more severe because of climate change. Therefore, evidence about the role of banks in providing funding to spur economic recovery is critical.
Investigations across different configurations of financial systems, such as bank- vs. market-based economies (e. g., Germany vs. the United States), allow for highlighting which components of financial systems seem better equipped to increase financial systems resiliency.
Second, the climate crisis requires economies to transform production technologies in order to source sustainable and renewable energy inputs. By using micro-data on German plants and their headquarters' banking relationships and information about the local and federal state leading political parties in Germany, the group aims to investigate the effects of political preferences for the green transition. This group's research will thereby enhance our understanding how climate policies balance the necessary need to reduce emissions with the economic burden imposed on agents during any large-scale transition of societies.
Third, the group's research analyses the role of culture in economies. The idea is that various aspects of culture, like religion, can work as a device that holds societies together and facilitate economic transactions. Using well-established empirical laboratories coming from significant natural disasters (for example, Hurricane Katrina in 2005), the group investigates whether local economies with a higher cultural imprint coming from religion found it easier to recover faster. Other incidents for which culture can play a vital role are big corporate scandals.
Using the Volkswagen Scandal from 2015, research by this group analyses the essential role of cultural imprints for consumer reactions in responding to large corporate scandals. This is important since government and regulatory intervention tend to come late or insufficient to punish corporate wrongdoings.

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.

Firm Social Networks, Trust, and Security Issuances
in: European Journal of Finance, No. 4, 2022
Abstract
We observe that public firms are more likely to issue seasoned stocks rather than bonds when theirs boards are more socially-connected. These connected issuers experience better announcement-period stock returns and attract more institutional investors. This social-connection effect is stronger for firms with severe information asymmetry, higher risk of being undersubscribed, and more visible to investors. Our conjecture is this social-network effect is driven by trust in issuing firms. Given stocks are more sensitive to trust, these trusted firms are more likely to issue stocks than bonds. Trustworthiness plays an important role in firms’ security issuances in capital markets.

Social Capital, Trusting, and Trustworthiness: Evidence from Peer-to-Peer Lending
in: Journal of Financial and Quantitative Analysis, No. 4, 2022
Abstract
How does social capital affect trust? Evidence from a Chinese peer-to-peer lending platform shows regional social capital affects the trustee’s trustworthiness and the trustor’s trust propensity. Ceteris paribus, borrowers from higher social capital regions receive larger bid from individual lenders, have higher funding success, larger loan size, and lower default rates, especially for low-quality borrowers. Lenders from higher social capital regions take higher risks and have higher default rates, especially for inexperienced lenders. Cross-regional transactions are most (least) likely to be realized between parties from high (low) social capital regions.

Commitment or Constraint? The Effect of Loan Covenants on Merger and Acquisition Activity
in: Finance Research Letters, June 2022
Abstract
We investigate how loan covenants associated with potential target firms affect takeover deals. We propose two possible channels. Under a discipline channel, the target firm becomes an attractive candidate for takeovers and merger deals are facilitated. Under a constraint channel, covenants hinder merger activity. We find support for the latter channel. Takeover likelihood is lower, deal failures are more common, the likelihood of price renegotiation is higher, and acquisition premium is lower when the target is bound by covenants. Covenant tightness exacerbates this effect.

Political Ties and Raising Capital in Global Markets: Evidence from Yankee Bonds
in: Journal of Corporate Finance, June 2022
Abstract
This paper examines whether state-to-state political ties help firms obtain better terms when raising funds in global capital markets. Focusing on the Yankee bonds market, we find that issuances by firms from countries with close political ties with the US feature lower yield spreads, higher issuance amounts, and longer maturities. Such an association is more pronounced for firms located in low income and highly indebted countries as well as firms in government-related industries, first-time issuers, and relatively smaller firms. Our study provides evidence supporting the notion that country-level political relationship is an important factor when raising capital in international markets.

Bank Failures, Local Business Dynamics, and Government Policy
in: Small Business Economics, No. 4, 2022
Abstract
Using MSA-level data over 1994–2014, we study the effect of bank failures on local business dynamics, in the form of net business formation and net job creation. We find that at least one bank failure in the metropolitan statistical area (MSA) with the mean population prevents approximately 475 net businesses from forming in that area, compared with MSAs that experience no bank failures, ceteris paribus. The equivalent effect on net job creation is 16,433 net job losses. Our results are even stronger for small businesses, which are usually more dependent on bank-firm relationships. These effects point to significant welfare losses stemming from bank failures, highlighting an important role for government intervention. We show that the Troubled Asset Relief Program (TARP) is effective in reducing the negative effects of bank failures on local business dynamics. This positive effect of TARP is quite uniform across small and large 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.

Bank-specific Shocks and House Price Growth in the U.S.
in: IWH Discussion Papers, No. 3, 2017
Abstract
This paper investigates the link between mortgage supply shocks at the banklevel and regional house price growth in the U.S. using micro-level data on mortgage markets from the Home Mortgage Disclosure Act for the 1990-2014 period. Our results suggest that bank-specific mortgage supply shocks indeed affect house price growth at the regional level. The larger the idiosyncratic shocks to newly issued mortgages, the stronger is house price growth. We show that the positive link between idiosyncratic mortgage shocks and regional house price growth is very robust and economically meaningful, however not very persistent since it fades out after two years.

How Effective is Macroprudential Policy during Financial Downturns? Evidence from Caps on Banks' Leverage
in: Working Papers of Eesti Pank, No. 7, 2015
Abstract
This paper investigates the effect of a macroprudential policy instrument, caps on banks' leverage, on domestic credit to the private sector since the Global Financial Crisis. Applying a difference-in-differences approach to a panel of 69 advanced and emerging economies over 2002–2014, we show that real credit grew after the crisis at considerably higher rates in countries which had implemented the leverage cap prior to the crisis. This stabilising effect is more pronounced for countries in which banks had a higher pre-crisis capital ratio, which suggests that after the crisis, banks were able to draw on buffers built up prior to the crisis due to the regulation. The results are robust to different choices of subsamples as well as to competing explanations such as standard adjustment to the pre-crisis credit boom.

Monetary Policy under the Microscope: Intra-bank Transmission of Asset Purchase Programs of the ECB
in: IWH Discussion Papers, No. 9, 2015
Abstract
With a unique loan portfolio maintained by a top-20 universal bank in Germany, this study tests whether unconventional monetary policy by the European Central Bank (ECB) reduced corporate borrowing costs. We decompose corporate lending rates into refinancing costs, as determined by money markets, and markups that the bank is able to charge its customers in regional markets. This decomposition reveals how banks transmit monetary policy within their organizations. To identify policy effects on loan rate components, we exploit the co-existence of eurozone-wide security purchase programs and regional fiscal policies at the district level. ECB purchase programs reduced refinancing costs significantly, even in an economy not specifically targeted for sovereign debt stress relief, but not loan rates themselves. However, asset purchases mitigated those loan price hikes due to additional credit demand stimulated by regional tax policy and enabled the bank to realize larger economic margins.
