Financial Markets

Research in this department centres on institutional changes in Europe’s financial markets. The department analyses the causes and consequences of banks’ international expansions, the link between market structures in banking and aggregate (financial) stability, contagion effects on international financial markets and the role of the financial system for the real economy.

The interdependence of the financial services sector with innovation and productivity in the real economy are of particular interest. Methodologically, research focuses on empirical methods that support analyses of feedback from the micro to the macro level and that allow for causal evaluations of regulatory interventions into financial systems.

Market Feedback Effect on CEO Pay: Evidence from Peers’ Say-on-Pay Voting Failures

Agnes Cheng Iftekhar Hasan Feng Tang Jing Xie

in: Journal of Financial and Quantitative Analysis, forthcoming

Abstract

<p>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.</p>

CEO Personality Traits and Compensation: Evidence from Investment Efficiency

Yao Du Iftekhar Hasan Chih-Yung Lin Chien-Lin Lu

in: Review of Quantitative Finance and Accounting, forthcoming

Abstract

<p>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&amp;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.</p>

Tax Authority Attention and Financial Reporting

Iftekhar Hasan Tahseen Hasan Kose John

in: International Journal of Banking, Accounting and Finance, forthcoming

Abstract

<p>We study the effects of Tax Authority (IRS) attention on a firm’s financial reporting. We explore whether firms institute a higher degree of accounting conservatism in response to IRS monitoring. Using data on IRS acquisition of public firms’ 10-K financial disclosures to proxy for IRS attention, we find that when firms are under IRS attention, they tend to initiate higher levels of unconditional and, to some extent, conditional accounting conservatism. We alleviate some of the endogeneity concerns by using pre- and post-IRS attention environments between the treated group (firms with IRS attention) and a propensity score that matches the control group of firms (no IRS attention). These results withstand several robustness tests and subsample analyses.</p>

How Do EU Banks’ Funding Costs Respond to the CRD IV? An Assessment Based on the Banking Union Directives Database

Thomas Krause Eleonora Sfrappini Lena Tonzer Cristina Zgherea

in: Journal of Financial Stability, forthcoming

Abstract

The establishment of the European Banking Union constitutes a major change in the regulatory framework of the banking system. Main parts are implemented via directives that show staggered transposition timing across EU member states. Based on the newly compiled Banking Union Directives Database, we assess how banks’ funding costs responded to the Capital Requirements Directive IV (CRD IV). Our findings show an upward trend in funding costs which is driven by an increase in cost of equity and partially offset by a decline in cost of debt. The diverging trends are most present in countries with an ex-ante lower regulatory capital stringency, which is in line with banks’ short-run adjustment needs but longer-run benefits from increased financial stability.

Carbon Transition Risk and Corporate Loan Securitization

Isabella Müller Huyen Nguyen Trang Nguyen

in: Journal of Financial Intermediation, forthcoming

Abstract

We examine how banks manage carbon transition risk by selling loans given to polluting borrowers to less regulated shadow banks in securitization markets. Exploiting the election of Donald Trump as an exogenous shock that reduces carbon risk, we find that banks’ securitization decisions are sensitive to borrowers’ carbon footprints. Banks are more likely to securitize brown loans when carbon risk is high but swiftly change to keep these loans on their balance sheets when carbon risk is reduced after Trump’s election. Importantly, securitization enables banks to offer lower interest rates to polluting borrowers but does not affect the supply of green loans. Our findings are more pronounced among domestic banks and banks that do not display green lending preferences. We discuss how securitization can weaken the effectiveness of bank climate policies through reducing banks’ incentives to price carbon risk.

What’s the Melting Pot Worth? Multiculturalism and House Prices

Rachel Cho Hisham Farag Christoph Görtz Danny McGowan Huyen Nguyen Max Schröder

in: IWH Discussion Papers, No. 11, 2025

Abstract

<p>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.</p>

Global Banks’ Macroeconomic Expectations and Credit Supply

Xiang Li Steven Ongena

in: IWH Discussion Papers, No. 8, 2025

Abstract

<p>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.</p>

From Rivals to Allies? CEO Connections in an Era of Common Ownership

Dennis Hutschenreiter Qianshuo Liu

in: IWH Discussion Papers, No. 7, 2025

Abstract

<p>Institutional common ownership of firm pairs in the same industry increases the likelihood of a preexisting social connection among their CEOs. We establish this relationship using a quasi-natural experiment that exploits institutional mergers combined with firms’ hiring events and detailed information on CEO biographies. In addition, for peer firms, gaining a CEO connection from a hiring firm’s CEO appointment correlates with higher returns on assets, stock market returns, and decreasing product similarity between companies. We find evidence consistent with common owners allocating CEO connections to shape managerial decisionmaking and increase portfolio firms’ performance.</p>

Illusive Compliance and Elusive Risk-shifting after Macroprudential Tightening: Evidence from EU Banking

Michael Koetter Felix Noth Fabian Wöbbeking

in: IWH Discussion Papers, No. 4, 2025

Abstract

<p>We study whether and how EU banks comply with tighter macroprudential policy (MPP). Observing contractual details for more than one million securitized loans, we document an elusive risk-shifting response by EU banks in reaction to tighter loan-to-value (LTV) restrictions between 2009 and 2022. Our staggered difference-in-differences reveals that banks respond to these MPP measures at the portfolio level by issuing new loans after LTV shocks that are smaller, have shorter maturities, and show a higher collateral valuation while holding constant interest rates. Instead of contracting aggregate lending as intended by tighter MPP, banks increase the number and total volume of newly issued loans. Importantly, new loans finance especially properties in less liquid markets identified by a new European Real Estate Index (EREI), which we interpret as a novel, elusive form of risk-shifting.</p>

Supply Chain Disruptions and Firm Outcomes

Michael Koetter Huyen Nguyen Sochima Uzonwanne

in: IWH Discussion Papers, No. 3, 2025

Abstract

<p>This paper examines how firms’ exposure to supply chain disruptions (SCD) affects firm outcomes in the European Union (EU). Exploiting heterogeneous responses to workplace closures imposed by sourcing countries during the pandemic as a shock to SCD, we provide empirical evidence that firms in industries relying more heavily on foreign inputs experience a significant decline in sales compared to other firms. We document that external finance, particularly bank financing, plays a critical role in mitigating the effects of SCD. Furthermore, we highlight the unique importance of bank loans for small and solvent firms. Our findings also indicate that highly diversified firms and those sourcing inputs from less distant partners are less vulnerable to SCD.</p>
