While major stock market indices are followed by large monetary investments, we document that membership decisions for the S&P 500 index have a nontrivial amount of discretion. We show that firms' purchases of S&P ratings appear to improve their chance of entering the index (but purchases of...

This paper derives analytical measures of the combined effects of tax changes and adjustment costs on investment and market value. Unlike earlier measures, the effective tax rate derived is valid in the presence of adjustment costs and anticipated tax changes. The derived measure of the impact...

The taxation of corporate assets is well understood to influence investment and firm valuation. This paper explores the consequences of postwar U.S. tax changes in a dynamic model which incorporates costs of adjustment and investor expectations of future tax reforms and macroeconomic...

Using hedge fund indices representing eight different styles, we find strong evidence of contagion within the hedge fund sector: controlling for a number of risk factors, the average probability that a hedge fund style index has extreme poor performance (lower 10% tail) increases from 2% to 21%...
