Relationship Lenders and Unorthodox Monetary Policy: Investment, Employment, and Resource Reallocation Effects
Leibniz-Gemeinschaft
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.

Softening Competition by Inducing Switching in Credit Markets: A Correction
in: Journal of Industrial Economics, Nr. 3, 2008
Abstract
In a recent article in this journal, Bouckaert and Degryse [2004] (denoted B&D) present a model in which banks strategically commit to disclosing borrower information. In this note, we point out an error in B&D and show that, although banks' information disclosure may indeed arise in equilibrium, it only does so if adverse selection is not too harsh.

The Impact of Competition on Bank Orientation
in: Journal of Financial Intermediation, Nr. 3, 2007
Abstract
How do banks react to increased competition? Recent banking theory significantly disagrees regarding the impact of competition on bank orientation—i.e., the choice of relationship-based versus transactional banking. We empirically investigate the impact of interbank competition on bank branch orientation. We employ a unique data set containing detailed information on bank–firm relationships. We find that bank branches facing stiff local competition engage considerably more in relationship-based lending. Our results illustrate that competition and relationships are not necessarily inimical.

Interbank Exposures: An Empirical Examination of Contagion Risk in the Belgian Banking System
in: International Journal of Central Banking, Nr. 2, 2007
Abstract
Robust (cross-border) interbank markets are important for the proper functioning of modern financial systems. However, a network of interbank exposures may lead to domino effects following the event of an initial bank failure. We investigate the evolution and determinants of contagion risk for the Belgian banking system over the period 1993–2002 using detailed information on aggregate interbank exposures of individual banks, large bilateral interbank exposures, and cross-border interbank exposures. The "structure" of the interbank market affects contagion risk. We find that a change from a complete structure (where all banks have symmetric links) toward a "multiplemoney-center" structure (where money centers are symmetrically linked to otherwise disconnected banks) has decreased the risk and impact of contagion. In addition, an increase in the relative importance of cross-border interbank exposures has lowered local contagion risk. However, this reduction may have been compensated by an increase in contagion risk stemming from foreign banks.

Repercusiones de la integración y consolidación de los sectores bancarios europeos sobre la innovación y las actividades de los emprendedores
in: Papeles de Economía Española, Nr. 110, 2006
Abstract
En este artículo se analiza si el programa de intensificación de la integración del sector financier europeo puede dañar a la innovación y al crecimiento en Europa. En particular, es preciso resaltar los problemas que dicha integración financiera puede ocasionar sobre los últimos avances en materia de desarrollo empresarial. La integración financiera, al intensificar la competencia y la consolidación del sector bancario europeo, podría poner en peligro la financiación procedente de las fuentes más innovadoras. Sin embargo, al sopesar los datos actuales, la conclusión es que estos problemas serían, a lo sumo, transitorios.

Crossing Networks Competition and Design
in: Competition and Regulation in Network Industries, Nr. 4, 2006
Abstract
In the past two decades, Alternative Trading Systems (ATSs) started to compete with traditional exchanges. Our paper focuses on one such system: a Crossing Network (CN). First, we discuss the distinct institutional aspects a CN offers compared to traditional markets. Next, we present an overview of the theoretical and empirical literature analyzing their success in competing with traditional markets. Finally, we offer some prospects on the potential outcome of this competition, taking into account market design issues such as the optimal degree of transparency of CNs. We also provide a market practioner’s view on the market design of CNs.

Ecological Preferences and the Carbon Intensity of Corporate Investment
in: IWH Discussion Papers, Nr. 2, 2025
Abstract
<p>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.</p>

Green Investing, Information Asymmetry, and Capital Structure
in: IWH Discussion Papers, Nr. 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, Nr. 10, 2023
Abstract
<p>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.</p>

Banking Market Deregulation and Mortality Inequality
in: Bank of Finland Research Discussion Papers, Nr. 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, Nr. 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>
