In the aftermath of the financial crisis, in several countries new levies on the financial sector have been proposed and in some cases implemented. We focus in particular on the recent introduction of a securities transaction tax (STT) in Italy. A peculiarity of the Italian STT is that it only concerns stocks of corporations with a market capitalization above € 500 million. We exploit this feature via a differences-in-differences approach – comparing taxed and non-taxed stocks before and after the introduction of the tax – and via a regression discontinuity design – comparing the performance of stocks just above the threshold with those just below. Focusing on the regulated market, we find that the new tax reduced liquidity, but it left transaction volumes and returns substantially unaffected. There is also evidence – although not conclusive – that the tax increased volatility

We examine the impact of the enactment of the Market Abuse Directive (MAD) and the Prospectus Directive (PD) across 18 EU countries on seasoned equity offerings (SEOs). Using a difference-in-differences methodology, we document a significant reduction in earnings management, improved post-SEO stock return performance, and a decline in the adverse reaction to SEO announcements following the enactment of MAD. We find similar, albeit weaker, results post-PD. The impact is stronger in countries with high ex-ante institutional quality. Our results suggest that the enactment of these directives leads to improvements in information quality, which reduces information asymmetry around SEOs.

We examine a potential link between culture and financial development by considering culture's influence on contract enforcement regulation. Specifically, we investigate the role of individualism in determining the variation in enforcement costs across countries. Individualism positively and significantly relates to efficient contract enforcement, an association that is independent of a particular political system. Interaction effects, however, suggest that democracy magnifies individualism's influence on the contract enforcement efficiency. These results provide insight into how culture can shape financial outcomes. It further suggests that culture serves as a constraint on policymakers, as any given policy or formal institutional structure will function very differently depending on the cultural environment

We study the impact of the enforcement of financial regulation by the United Kingdom’s regulatory authorities on the market price of penalized firms. Existing studies rely on analyses of multiple events that may distort the measurement of reputational losses. In the United Kingdom, the entire enforcement process involves only one public announcement and is accompanied by complete information on legal penalties. We find that reputational losses are nearly nine times the size of fines and are associated with misconduct harming customers or investors but not third parties

The unique regulation of U.S. public pension funds links their liability discount rate to the expected return on assets, which gives them incentives to invest more in risky assets in order to report a better funding status. Comparing public and private pension funds in the United States, Canada, and Europe, we find that U.S. public pension funds act on their regulatory incentives. U.S. public pension funds with a higher level of underfunding per participant, as well as

U.S. antitrust agencies claim their antitrust enforcement mission is to protect consumers, promote fair competition, and maintain efficiency. Are antitrust practices consistent with this claim? We explore this question by examining antitrust selection of horizontal merger cases in the U.S. manufacturing sector during 1980–2009. We find that antitrust agencies are more likely to intervene when foreign import pressure is low, merger industry concentration hits a hurdle level, or local or less specialized rivals suffer unfavorable wealth effects. We find no evidence that antitrust agencies systematically respond to the wealth effects of either customers in general or more affected customers. Our findings can be a useful reference for calibrating the efficiency of antitrust regulation and enforcement

Bank capital is the cornerstone of bank regulation and is considered a key determinant of a bank's ability to withstand economic shocks. In the area of bank capital regulation, the general view is that more bank capital is better, irrespective of who provides it. In this paper, we investigate whether the investment horizon of bank capital providers matters for bank performance during the recent financial crisis. We observe that banks with more short-term investor ownership have worse stock returns during the crisis. Further exploration suggests that this is partially because banks with higher short-term investor ownership took more risk prior to the crisis but mainly because they experienced higher selling pressure during the crisis. Our results confirm the economic benefit of bank capital in helping banks to perform better during crises. However, when we decompose bank capital by the nature of its providers, we show that more capital is associated with worse performance when it is provided by short-term institutional investors

This paper examines the impact of stock liquidity on firm bankruptcy risk. Using the Securities and Exchange Commission decimalization regulation as a shock to stock liquidity, we establish that enhanced liquidity decreases default risk. Stocks with the highest default risk experience the largest improvements. We find two mechanisms through which stock liquidity reduces firm default risk: improving stock price informational efficiency and facilitating corporate governance by blockholders. Of the two mechanisms, the informational efficiency channel has higher explanatory power than the corporate governance channel

We examine the impact of trading on markets partially exempt from National Market System requirements (“dark venues”) on equity-market quality. We find evidence consistent with the notion that dark venues rely on their special features to segregate order flow based on asymmetric information risk, which results in their transactions being less informed and contributing less to price discovery on the consolidated market. Except for the execution of large transactions and trading in small stocks, the effects of dark-venue order segmentation are damaging to overall market quality. Our results have important implications for the regulation of international equity markets
