We consider 5 measures of corporate governance during the period 1998–2007. We find a significant negative relationship between board independence and operating performance during the pre-2002 period, but a positive and significant relationship during the post-2002 period. Our most important contribution is a proposal of a governance measure, namely, dollar ownership of the board members, that is simple, intuitive, less prone to measurement error, and not subject to the problem of weighting a multitude of governance provisions in constructing a governance index.

By providing an anchor for measuring the impact of events on investor wealth, the methodology offers a fruitful means for evaluating the welfare implications of private and government actions. This paper is the first in a set of two papers that review the use and impact of the event study methodology in the legal domain. This paper begins by briefly reviewing the event study methodology and its strengths and limitations for policy analysis. It then reviews in detail how event studies have been used to evaluate the wealth effects of corporate litigation: Defendants experience economically-meaningful and statistically-significant wealth losses upon the filing of the suit, whereas plaintiff firms experience no significant wealth effects upon filing a lawsuit. Also, there is a significant wealth increase for defendant firms when they settle a suit with another firm, in contrast to other types of plainti...

Once we control for IPO fundamentals (such as, income, sales, book equity, growth opportunities, insider retention, and investment banker prestige) and allow for different valuation of these fundamentals across different time-periods, average valuations of IPOs in the recent boom and crash periods were not statistically different from those of the late 1980s. We also document some shifts in the valuation of fundamentals across time-periods. Most interestingly, contrary to anecdotes in the financial press, income of IPO firms is weighted more when valuing IPOs in the boom period compared to the late eighties. With respect to inter-industry differences, we document that t...

To address endogeneity between a bank’s equity capital ratio and risk of balance sheet assets, we use an instrumental variable approach, as well as a triple differences approach. We find a 10 percentage point increase in the book equity capital ratio is associated with a 92 basis points increase in the bank’s cost of capital. We also find that a 10 percentage point increase in the market equity capital ratio is associated with a 59 basis points increase in the bank’s cost of capital. Restricting the analysis to large banks with book assets in excess of $50 billion, we find that a 10 percentage point increase in the book equity capital ratio is associated with a 23 basis points increase in the bank’s cost of capital. Even though an increase in the equity capital ratio is associated with a...

The bidder's abnormal return at the time of the bid gives a biased estimate of the market's valuation of the bidder's gain from takeover, because the form of the offer and the very fact that the bidder makes an offer may convey information about the stand-alone value of the bidder. For example, the fact of a bid may convey the good news that a bidder expects to have high cash flows, or the bad news that the bidder has poor internal investment opportunities. We provide a technique , the intervention method, that extracts the market's estimate of the value improvement due to the takeover from the abnormal return of the initial bidder when a competing bid arrives. The associated stock return is informative about value improvement because this event has a large effect on the probability of the initial bidder's success. Furthermore, thi...

What is the relationship between corporate governance and performance? This paper sheds light on these questions while taking into account the endogeneity of the relationships among corporate governance, corporate performance, corporate capital structure, and corporate ownership structure. We make three additional contributions to the literature: First, we find that better governance as measured by the Gompers, Ishii, and Metrick [Gompers, P.A., Ishii, J.L., and Metrick, A., 2003, Corporate governance and equity prices, Quarterly Journal of Economics 118(1), 107–155.] and Bebchuk, Cohen and Ferrell [Bebchuk, L., Cohen, A., and Ferrell, A., 2004, What matters in corporate governance?, Working paper, Harvard Law School] indices, stock ownership of boardmembers, and CEO-Chair separation is significantly positively correlated with better contemporaneous and subsequent operating performance. Second, contrary to claims in...

Our text-based measure gives a useful description of innovation by mature firms with and without patenting and R&D. For non-patenting firms, the measure identifies firms that adopt novel technologies and innovative business practices (e.g., Walmart’s cross-geography logistics). For patenting firms, the text-based measure strongly correlates with valuable patents, which likely capture true innovation. The text-based measure robustly forecasts greater firm performance and growth opportunities for up to four years, and these value implications hold just as strongly for non-patenting firms. ⇤Previous versions of the paper were circulated under its former title, “A Text-Based Analysis of Corporate Innovation.” All authors are from University of Colorado’s Leeds School of Business.

We argue that under certain broad assumptions, the admonition remains a good place to start. To strengthen the prospects for success of long-term shareholder value maximization, we suggest steps to align shareholder wealth maximization with stakeholder interests. First, antitrust public policies should be vigorously enforced to maintain and enhance competition in product markets and labor markets. Second, management and board compensation should be reformed to focus on creating and sustaining long-term shareholder value. Finally, and more importantly, for many of society’s serious challenges, corporations do not represent the appropriate level of action. Climate change, for example, poses significant challenges for societies and businesses. But significant changes to combat climate change require public policy changes in the United States and abroad. Turning more to corporations because the political process seems broken will not do.

The economic impact of net income is largest for Chinese IPOs and smallest for Australian IPOs. Book value is positively and significantly related to IPO valuation in only Canada, Germany, India, and U.S. Capital expenditure is significantly and positively related to IPO valuation in only Canada, Germany, India, U.K., and U.S. We find a positive and statistically significant relation between insider retention and IPO valuation only in China, Germany, U.K., and U.S.; positive but marginally significant relationship for India and Japan. Underwriter reputation has a positive and statistically significant relationship for IPOs only in China, Germany, India, U.K., and U.S. Net income is positively and statistically significantly related to IPO valuation during the years 1998-2015, and this relationship has strengthened over time. Capital expenditure is positively and significantly related to IPO value during 1998-2015, and this relation appears to be stable over time.

Many commentators and institutional investors believe that a "monitoring board," composed almost entirely of independent directors, is an important component of good corporate governance. The empirical evidence reported in this Article challenges that conventional wisdom. We conduct the first large-sample, long-horizon study of whether the degree of board independence (proxied by the fraction of independent directors minus the fraction of inside directors on a company's board) correlates with various measures of the long-term performance of large American firms. We find evidence that low-profitability firms increase the independence of their boards of directors. But there is no evidence that this strategy works. Firms with more independent boards do not perform better than other firms. Our results support efforts by firms to experiment with board structures that depart from the conventional monitoring board. Note: This paper is identical to the article as published in the Journal of Corporation Law.
