Finanzmärkte
Die Abteilung „Finanzmärkte“ am IWH befasst sich mit dem institutionellen Wandel von Finanzsystemen in Europa. Die Forschung der Abteilung beschäftigt sich mit den Ursachen und Wirkungen der internationalen Tätigkeit von Banken und anderen Finanzintermediären, dem Zusammenhang zwischen Marktstrukturen im Bankensektor und gesamtwirtschaftlicher Stabilität, Ansteckungseffekten auf internationalen Finanzmärkten sowie der Rolle des Finanzsektors für die Realwirtschaft.
Hierbei spielen insbesondere Wechselwirkungen zwischen dem Finanzsektor und Wachstums- und Innovationsprozessen in der Realwirtschaft eine Rolle. Methodisch zielt die Forschung der Abteilung auf die integrierte Betrachtung von Anpassungen auf der Mikro- und Makroebene sowie die Evaluation wirtschaftspolitischer Maßnahmen zur Regulierung von Finanzmärkten.

Market Feedback Effect on CEO Pay: Evidence from Peers’ Say-on-Pay Voting Failures
in: Journal of Financial and Quantitative Analysis, im Erscheinen
Abstract
We find that a firm’s stock price drops when its compensation peer firm announces a severe say-on-pay voting failure. This price drop causes a reduction in the focal firm CEO’s pay in the following period. The effect on CEO pay is stronger when the board of directors is more powerful, when the proxy advisor holds a negative view of the CEO’s pay, and when the hired compensation consultant is less reputable. Directors who cut their CEO’s pay following the price drop receive more voting support from investors than other directors. Our findings show that the peer firm’s voting failure induces a market-feedback effect for focal firm directors.
CEO Personality Traits and Compensation: Evidence from Investment Efficiency
in: Review of Quantitative Finance and Accounting, im Erscheinen
Abstract
We examine the effects of the big five personalities of CEOs (openness, conscientiousness, extroversion, agreeableness, and neuroticism) on their annual compensation. We hand-collect the tweets of S&P 1500 CEOs and use IBM's Watson Personality Insights to measure their personalities. CEOs with high ratings of agreeableness and conscientiousness get more compensation. We further find that the firms with these CEOs outperform their peers due to better investment efficiency. Firms are willing to pay higher compensation for talent, especially for firms with better operations, located in states with higher labor unionization, or facing higher competition in the product market. Overall, CEO personality is a valid predictor of CEOs' compensation.
Does It Pay to Get Connected? An Examination of Bank Alliance Network and Bond Spread
in: Journal of Economics and Business, im Erscheinen
Abstract
This paper examines the effects of bank alliance network on bonds issued by European banks during the period 1990–2009. We construct six measures capturing different dimensions of banks’ network characteristics. In opposition to the results obtained for non-financial firms, our findings indicate that being part of a network does not create value for bank’s bondholders, indicating a dark side effect of strategic alliances in the banking sector. While being part of a network is perceived as a risk-increasing event by market participants, this negative perception is significantly lower for the larger banks, and, to a lesser extent, for the more profitable banks. Moreover, during crisis times, the positive impact on bond spread of a bank’s higher centrality or of a bank’s higher connectedness in the network is stronger, indicating that market participants may fear spillover effects within the network during periods of banks’ heightened financial fragility.
Deposit Competition and Mortgage Securitization
in: Journal of Money, Credit and Banking, im Erscheinen
Abstract
We study how deposit competition affects a bank's decision to securitize mortgages. Exploiting the state-specific removal of deposit market caps across the U.S. as a source of competition, we find a 7.1 percentage point increase in the probability that banks securitize mortgage loans. This result is driven by an 11 basis point increase in deposit costs and corresponding reductions in banks' deposit holdings. Our results are strongest among banks that rely more on deposit funding. These findings highlight a hitherto undocumented and unintended regulatory cause that motivates banks to adopt the originate-to-distribute model.
A Note on the Use of Syndicated Loan Data
in: International Finance, im Erscheinen
Abstract
Syndicated loan data provided by DealScan is an essential input in banking research to answer urging questions on bank lending, e.g., in the presence of financial or geopolitical 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.

The Price of Beauty: Biodiversity Effects on Residential Housing Markets
in: IWH Discussion Papers, Nr. 21, 2025
Abstract
We study how and why local biodiversity affects residential property values. Leveraging remotely sensed greenness indicators and a novel dataset of granular property listings, we examine how changes in vegetation load on real estate prices. Hikes in greenness are associated with higher listing prices, fewer properties listed, and reduced liquidity in housing markets. These results suggest that price hikes in housing markets are driven by supply-side constraints instead of a “greenium” that buyers might be willing to pay due to innate preferences. Exogenous zoning shocks to foster biodiversity corroborate the presence of supply side constraints as price drivers in residential housing markets. Our findings emphasize the need to calibrate biodiversity and (social) housing policy objectives more explicitly.
Employment Responses to Increased Biodiversity Transition Risk
in: IWH Discussion Papers, Nr. 20, 2025
Abstract
This paper examines how firms adjust the number and types of workers they hire in response to increased biodiversity transition risk. Using the adoption of the Key Biodiversity Areas Standard of 2016 as a source of variation that increases the risk of future land-use restrictions, we find that firms reduce job postings in affected areas and reallocate labor to less exposed regions. This effect is concentrated among firms that make negative impacts on biodiversity. Cuts are stronger among production roles, while hiring in green and adaptive occupations increases. The effect is not driven by changes in capital investment or workers’ labor supply decisions. Our findings contribute to the ongoing debate on the costs and benefits of biodiversity conservation policies and their implications for labor market outcomes.
Information Flow and Market Efficiency - The Economic Impact of Precise Language
in: IWH Discussion Papers, Nr. 13, 2025
Abstract
This paper examines the impact of complex yet precise language, particularly financial jargon, on information dissemination and ultimately market efficiency. As a natural laboratory, we analyze the information exchanged during earnings conference calls, where we instrument jargon with the Plain Writing Act of 2010. Our findings suggest that the Act‘s promotion of plain language usage results in a reduction in complex financial jargon for US firms. However, in contrast to the presumed benefits of accessible language, this reduction in jargon is associated with a decrease in market efficiency, implying that the Act may inadvertently hinder information flow. This finding is particularly important at the juncture where human-generated information is received by machines, which are known to be vunerable to ambiguous inputs.
What’s the Melting Pot Worth? Multiculturalism and House Prices
in: IWH Discussion Papers, Nr. 11, 2025
Abstract
Is there a multicultural neighborhood price premium? We exploit plausibly exogenous variation in British colonization patterns in Northern Ireland during the early 1600s which created neighborhoods of varying religious composition that persists until today. These religious groups are culturally distinct, but are observationally equivalent ethnically and socioeconomically. A standard deviation increase neighborhood-level multiculturalism raises house prices by 9.6%. Multiculturalism raises property prices by increasing asset liquidity and housing demand as a wider spectrum of society demand houses in these areas. The findings and mechanism contrast sharply with prior evidence showing negative relationships due to homophily, social networks, and identification challenges.
Global Banks’ Macroeconomic Expectations and Credit Supply
in: IWH Discussion Papers, Nr. 8, 2025
Abstract
We investigate how global banks’ macroeconomic expectations for borrower countries influence their credit supply. Utilizing granular data on varying expectations among banks lending to the same firm at the same time, combined with an instrumental variable approach, we find that more optimistic GDP growth expectations for a borrower country are strongly linked to increased credit supply. Specifically, a one standard deviation increase in a lender’s GDP growth expectation for the borrower’s country corresponds to an increase of 8.46 percentage points in the loan share, equivalent to approximately 0.75 standard deviations of the loan share and $75.35 million in loan amount. In contrast, global banks’ short-term inflation expectations do not show a significant impact on their credit supply.
