This paper examines the effect of institutional investors? investment duration on the efficiency of stock prices. Using a new duration measure based on quarterly institutional investors? portfolio holdings, the presence of short-term institutional investors can help explain many of the...

This paper examines the impact on shareholder voting of the mutual fund voting disclosure regulation adopted by the SEC in 2003, using a paired sample of proposals submitted before and after the rule change. We focus on how voting outcomes relate to institutional ownership and the voting...

We investigate the effects of shareholder governance mechanisms on bondholders and document two new findings. First, the impact of shareholder control (proxied by large institutional blockholders) on credit risk depends on takeover vulnerability. Shareholder control is associated with higher...

his paper introduces a dataset tracking approximately 1,000 firms’ G- and E-index scores, as well the individual corporate governance provisions constituting these indexes, over the 1978-1989 period. Combining this data with the 1990-2006 IRRC data, we are able to track firms’...

This paper studies the interaction between takeover defenses and product market competition. We find that firms in more competitive industries have more takeover defenses. This is the opposite result from what one would expect if takeover defenses always constitute an inefficient outcome that...

Standard Fama-French and Carhart models produce economically and statistically significant nonzero alphas even for passive benchmark indices such as the S&P 500 and Russell 2000. We find that these alphas primarily arise from the disproportionate weight the Fama-French factors place on small...

This paper reinvestigates the performance of risk-based multifactor models. In particular, we generalize the Bayesian methodology of Shanken (1987b) and Kandel, McCulloch and Stambaugh (1995) from mean-variance efficiency to the ICAPM notion of multifactor efficiency. This methodology uses...

This paper explores the role played by multiple credit rating agencies (CRAs) in the market for corporate bonds. Moody’s, S&P and Fitch operate in a competitive setting with market demand for both credit information and the certification value of a high rating. We empirically document the...

We introduce a new measure of active portfolio management, Active Share, which represents the share of portfolio holdings that differ from the benchmark index holdings. We compute Active Share for domestic equity mutual funds from 1980 to 2003. We relate Active Share to fund characteristics such...

This paper introduces measures of volatility and skewness that are based on individual stock options to explain credit spreads on corporate bonds. Implied volatilities of individual options are shown to contain important information for credit spreads and improve on both implied volatilities of...
