Abstract
This study examines how antitrust law adoptions affect horizontal merger and acquisition (M&A) outcomes. Using the staggered introduction of competition laws in 20 countries, we find antitrust regulation decreases acquirers’ five-day cumulative abnormal returns surrounding horizontal merger announcements. A decrease in deal value, target book assets, and industry peers' announcement returns are consistent with the market power hypothesis. Exploiting antitrust law adoptions addresses a downward bias to an estimated effect of antitrust enforcement (Baker (2003)). The potential bias from heterogeneous treatment effects does not nullify our results. Overall, antitrust policies seem to deter post-merger monopolistic gains, potentially improving customer welfare.

Creditor-control Rights and the Nonsynchronicity of Global CDS Markets
Iftekhar Hasan, Miriam Marra, Eliza Wu, Gaiyan Zhang
Review of Corporate Finance Studies,
im Erscheinen
Abstract
We analyze how creditor rights affect the nonsynchronicity of global corporate credit default swap spreads (CDS-NS). CDS-NS is negatively related to the country-level creditor-control rights, especially to the “restrictions on reorganization” component, where creditor-shareholder conflicts are high. The effect is concentrated in firms with high investment intensity, asset growth, information opacity, and risk. Pro-creditor bankruptcy reforms led to a decline in CDS-NS, indicating lower firm-specific idiosyncratic information being priced in credit markets. A strategic-disclosure incentive among debtors avoiding creditor intervention seems more dominant than the disciplining effect, suggesting how strengthening creditor rights affects power rebalancing between creditors and shareholders.

Drehtüren in den Vorstandsetagen der Finanzaufsicht: Sind Banker oder Bürokraten die besseren Aufseher?
Michael Koetter, Noel Nietzold
Wirtschaft im Wandel,
Nr. 2,
2024
Abstract
Der „umgekehrte Drehtüreffekt“ beschreibt das Phänomen, wenn ehemalige Bankerinnen und Banker Vorstandspositionen in nationalen Aufsichtsbehörden (National Supervisory Agency, NSA) bekleiden. Ein neu erhobener Datensatz zeigt, dass etwa ein Drittel der Vorstandsmitglieder in europäischen NSA vorher in der Finanzindustrie tätig war. Die Bestellung ehemaliger Banker in NSA-Vorstände geht mit positiven Börsenreaktionen einher, was auf eine „Näheprämie“ in der Bewertung beaufsichtigter Banken hindeutet. Im Gegensatz dazu ruft die Berufung von Bürokraten ohne praktische Vorkenntnisse in der Bankenwelt negative Börsenreaktionen hervor. Bis zur Einführung des Einheitlichen Aufsichtsmechanismus (Single Supervisory Mechanism, SSM) in Europa korreliert die Präsenz ehemaliger Banker in NSA-Vorständen mit einer geringeren regulatorischen Kapitalquote, was auf einen nachsichtigeren Aufsichtsstil schließen lässt.

The Reverse Revolving Door in the Supervision of European Banks
Stefano Colonnello, Michael Koetter, Alex Sclip, Konstantin Wagner
IWH Discussion Papers,
Nr. 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.

Herding Behavior and Systemic Risk in Global Stock Markets
Iftekhar Hasan, Radu Tunaru, Davide Vioto
Journal of Empirical Finance,
September
2023
Abstract
This paper provides new evidence of herding due to non- and fundamental information in global equity markets. Using quantile regressions applied to daily data for 33 countries, we investigate herding during the Eurozone crisis, China’s market crash in 2015–2016, in the aftermath of the Brexit vote and during the Covid-19 Pandemic. We find significant evidence of herding driven by non-fundamental information in case of negative tail market conditions for most countries. This study also investigates the relationship between herding and systemic risk, suggesting that herding due to fundamentals increases when systemic risk increases more than when driven by non-fundamentals. Granger causality tests and Johansen’s vector error-correction model provide solid empirical evidence of a strong interrelationship between herding and systemic risk, entailing that herding behavior may be an ex-ante aspect of systemic risk, with a more relevant role played by herding based on fundamental information in increasing systemic risk.

Institutions and Corporate Reputation: Evidence from Public Debt Markets
Xian Gu, Iftekhar Hasan, Haitian Lu
Journal of Business Ethics,
Nr. 1,
2023
Abstract
Using data from China’s public debt markets, we study the value of corporate reputation and how it interacts with legal and cultural forces to assure accountability. Exploring lawsuits that change corporate reputation, we find that firms involved in lawsuits experience a decrease in bond values and a tightening of borrowing terms. Using the heterogeneities in legal and social capital environments across Chinese provinces, we find the effects are more pronounced for private firms, firms headquartered in provinces with low legal protections, and firms headquartered in provinces with high social capital. The results show that lawsuits that allege misconduct are associated with reputational penalties and that such penalties serve as substitutes for legal protections and as complements to cultural forces to provide ex post accountability and motivate ex ante trust.
