In the last two decades, over 75% of U.S. industries have experienced an increase in concentration levels. We find that firms in industries with the largest increases in product market concentration have enjoyed higher profit margins and more profitable M&A deals. At the same time, we do not...

Using an agent-based model (ABM) with fundamentalists and chartists, prone to develop bubbles and crashes, we demonstrate the usefulness of direct market intervention by a policy maker, documenting strong performance in preventing bubbles and drawdowns and augmenting significantly the welfare of...

Using a new dataset of corporate voting-rights from 1971 to 2015, we find that young dual-class firms trade at a premium and operate at least as efficiently as young single-class firms. As dual-class firms mature, their valuation declines, and they become less efficient in their margins,...

We study the determinants of private benefits of control in negotiated block transactions. We estimate the block pricing model in Burkart, Gromb, and Panunzi (2000) explicitly dealing with the existence of both block premia and block discounts in the data. We find evidence that the occurrence of...

Following surprise independent director departures, affected firms have worse stock and operating performance, are more likely to restate earnings, face shareholder litigation, suffer from an extreme negative return event, and make worse mergers and acquisitions. The announcement returns to...

We study changes in the design of CEO contracts when firms transition from being public with dispersed ownership to being private with strong principals in the form of private equity sponsors. These principals redesign many, but far from all, contract features. There is no evidence that they...

This paper provides a cross-country analysis to determine whether CEO turnover is a credible threat, whether it is effective in delivering performance improvements, and whether better governance improves credibility and effectiveness of CEO turnover. The analysis is based on a detailed panel of...

Between 2007 and 2016, 7.6% of publicly listed U.S. firms disclosed that their CEOs had pledged company stock as collateral for a loan. On average, CEOs pledge 38% of their shares. The mean loan value is an economically sizeable $65 million. CEOs use the funds to either double down (6.0%), hedge...

Mutual funds must publish policies announcing how they generally vote on the different ballot items at the shareholder meetings of their portfolio firms. I manually collect 17,000 of these policies for a sample of 29 of the largest U.S. mutual fund families over 2006-2018. I find that voting...

Directors are more likely to obtain additional directorships, especially at prestigious firms, if the CEOs of their current boards are well-connected. Recommended directors do not become beholden to the CEO, as CEO compensation is unaffected and an analysis of appointment announcement returns...
