Governance and Finance
Corporate governance today is about more than just making profits for shareholders. It now aims to balance the needs of all stakeholders-employees, investors, creditors, and business partners. Good governance helps companies run better, attract talent, gain customer trust, and lower financial costs. Conversely, poor governance can lead to scandals, job losses, and broken contracts.
The “Governance and Finance” research group studies how governance works in modern financial markets. One of the focuses is on how firms choose, motivate, and keep talented leaders, especially CEOs, since exemplary leadership is key to company success.
The group is also interested in investigating how changes in financial markets, like the rise of big shareholders, activist investors, or even creditors, affect company decisions. The goal is to understand how different players and institutions influence company behavior and what that means for the future of business.

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

Poison Bonds
in: IWH Discussion Papers, No. 3, 2024
Abstract
This paper documents the rise of “poison bonds”, which are corporate bonds that allow bondholders to demand immediate repayment in a change-of-control event. The share of poison bonds among new issues has grown substantially in recent years, from below 20% in the 90s to over 60% since mid-2000s. This increase is predominantly driven by investment-grade issues. We provide causal evidence that the pressure to eliminate poison pills has led firms to issue poison bonds as an alternative. Our analysis suggests that this practice entrenches incumbent managers and destroys shareholder value. Holding a portfolio of firms that remove poison pills but promptly issue poison bonds results in negative abnormal returns of −7.3% per year. Our findings have important implications for the agency theory of debt: (i) more debt may not discipline the management; and (ii) even without financial distress, managerial entrenchment can lead to agency conflicts between shareholders and creditors.

The Reverse Revolving Door in the Supervision of European Banks
in: IWH Discussion Papers, No. 25, 2023
Abstract
We show that around one third of executive directors on the boards of national supervisory authorities (NSA) in European banking have an employment history in the financial industry. The appointment of executives without a finance background associates with negative valuation effects. Appointments of former bankers, in turn, spark positive stock market reactions. This „proximity premium“ of supervised banks is a more likely driver of positive valuation effects than superior financial expertise or intrinsic skills of former executives from the financial industry. Prior to the inception of the European Single Supervisory Mechanism, the presence of former financial industry executives on the board of NSA associates with lower regulatory capital and faster growth of banks, pointing to a more lenient supervisory style.

Poison Bonds
in: SSRN Discussion Paper, 2023
Abstract
This paper documents the rise of "poison bonds", which are corporate bonds that allow bondholders to demand immediate repayment in a change-of-control event. The share of poison bonds among new issues has grown substantially in recent years, from below 20% in the 90s to over 60% after 2005. This increase is predominantly driven by investment-grade issues. We provide causal evidence that the pressure to eliminate poison pills has led firms to issue poison bonds as an alternative. Further analyses suggest that this practice entrenches incumbent managers, coincidentally benefits bondholders, but destroys shareholder value. Holding a portfolio of firms that remove poison pills but promptly issue poison bonds results in negative abnormal returns of -7.3% per year. Our findings have important implications for understanding the agency benefits and costs of debt: (1) more debt does not necessarily discipline the management; and (2) even without financial distress, managerial entrenchment can lead to conflicts between shareholders and creditors.
