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
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.

When Arm’s Length is too Far: Relationship Banking over the Credit Cycle
in: Journal of Financial Economics, No. 1, 2018
Abstract
We conduct face-to-face interviews with bank CEOs to classify 397 banks across 21 countries as either relationship or transaction lenders. We then use the geographic coordinates of these banks’ branches and of 14,100 businesses to analyze how the lending techniques of banks in the vicinity of firms are related to credit constraints at two contrasting points of the credit cycle. We find that while relationship lending is not associated with credit constraints during a credit boom, it alleviates such constraints during a downturn. This positive role of relationship lending is stronger for small and opaque firms and in regions with a more severe economic downturn. Moreover, our evidence suggests that relationship lending mitigates the impact of a downturn on firm growth and does not constitute evergreening of loans.
Politically Connected Firms in Poland and Their Access to Bank Financing
in: Communist and Post-Communist Studies, No. 4, 2017
Abstract
This paper characterizes politically connected firms and their access to bank financing. We determine that the relationship between political connections and access to long-term bank loans is weaker in Poland than in other emerging economies. The most probable explanation for this result is related to the instability of the political climate in Poland. We find that only certain kinds of political connections, such as recent connections, positively influenced access to bank financing during the sample period from 2001 to 2011. Moreover, we obtain also some evidence that the value of political connections increased during the 2007 crisis period and onward.
Bank Financing, Institutions and Regional Entrepreneurial Activities: Evidence from China
in: International Review of Economics and Finance, November 2017
Abstract
We investigate the effects of bank financing on regional entrepreneurial activities in China. We present contrasting findings on the role of quantity vs. quality of bank financing on small business formation in China: while we document a consistent, significantly positive relationship between the quality of bank financing and new venture formation, we find that the quantity of supplied credit is insignificant. We report that formal institutions are positively correlated to regional entrepreneurial activities, and informal institutions substitute formal institutions. Our findings also reveal that the institutional environment tends to supplement bank financing in promoting regional entrepreneurial activities.
Bank Overall Financial Strength: Islamic Versus Conventional Banks
in: Economic Modelling, 2017
Abstract
A number of recent studies compare the performance of Islamic and conventional banks with the use of individual financial ratios or efficiency frontier techniques. The present study extends this strand of the literature, by comparing Islamic banks, conventional banks, and banks with an Islamic window with the use of a bank overall financial strength index. This index is developed with a multicriteria methodology that allows us to aggregate various criteria capturing bank capital strength, asset quality, earnings, liquidity, and management quality in controlling expenses. We find that banks differ significantly in terms of individual financial ratios; however, the difference of the overall financial strength between Islamic and conventional banks is not statistically significant. This finding is confirmed with both univariate comparisons and in multivariate regression estimations. When we look at the bank financial strength within regions, we find that conventional banks outperform both the Islamic banks and the banks with Islamic window in the case of Asia and the Gulf Cooperation Council; however, Islamic banks perform better in the MENA and Senegal region. Second stage regressions also reveal that the bank overall financial strength index is influenced by various country-specific attributes. These include control of corruption, government effectiveness, and operation in one of the seven countries that are expected to drive the next big wave in Islamic finance.
Enforceability of Noncompetition Agreements and Firm Innovation: Does State Regulation Matter?
in: Innovation: Organization & Management, No. 2, 2017
Abstract
In this study, we examine how noncompetition agreements and the mobility of human capital – a core asset of any firm – affect innovations of publicly traded firms in the United States. We find that firms in states with stricter noncompetition enforcement have fewer patent applications. We also examine patent forward citations and find that tougher enforcement of such contracts is associated with less innovative patents. Notably, we find that stronger enforcement of noncompetition agreements impedes innovation for firms facing intense industry labor mobility. High-powered, equity-based compensation positively moderates the relationship between noncompetition enforcement and innovation, but only for the quality of innovation.

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.
A Note on the Use of Syndicated Loan Data
in: IWH Discussion Papers, No. 17, 2022
Abstract
<p>Syndicated loan data provided by DealScan is an essential input in banking research. This data is rich enough to answer urging questions on bank lending, e.g., in the presence of financial shocks or climate change. However, many data options raise the question of how to choose the estimation sample. We employ a standard regression framework analyzing bank lending during the financial crisis of 2007/08 to study how conventional but varying usages of DealScan affect the estimates. The key finding is that the direction of coefficients remains relatively robust. However, statistical significance depends on the data and sampling choice and we provide guidelines for applied research.</p>
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.
