We examine the effect of litigation risk on managers' decision to issue earnings forecasts. We use a new ex ante measure of litigation risk, namely, the Directors and Officers liability insurance premium. This choice bypasses significant problems associated with the estimation of ex ante...

We investigate differences in book prices between the United States and other countries. We find that general audience books are similarly priced internationally, but textbooks are substantially more expensive in the United States (often more than double the price). This disparity is much more...

A central goal in devising a system of courts is to make judicial services easily accessible. As a consequence, justice is usually administered in a geographically decentralized fashion: trial courts are distributed across the territory in which the jurisdiction's law is applied. Corporate law,...

Ragnar Frisch proposed in 1936 a procedure for estimating natural variable values by modifying what are now called structural macroeconometric models. This paper shows that Frisch's procedure can be used to illuminate natural concepts using today's models. The procedure also forces one to be...

This note is a response to a recent paper by Erb and Harvey (2005). We show that diversification returns are mathematical properties of geometric averages of index returns, and not due to rebalancing. We also show how rebalancing affects the performance of the equal-weighted commodity futures...

Litigation risk has been hypothesized to affect managerial behavior in a number of ways. An understanding of the determinants of litigation risk is a necessary first step to analyzing managerial behavior. We examine the determinants of an ex-ante measure of litigation risk, namely, Directors and...

We present a unified approach to value at risk analysis under heavy-tailedness using new majorization theory for linear combinations of thick-tailed random variables that we develop. Among other results, we show that the stylized fact that portfolio diversification is always preferable is...

This paper reviews recent developments in methods for dealing with weak instruments (IVs) in IV regression models. The focus is more on tests (and confidence intervals derived from tests) than estimators. The paper also presents new testing results under "many weak IV asymptotics," which are...

Junk e-mail or spam is rapidly choking off e-mail as a reliable and efficient means of communication over the Internet. Although the demand for human attention increases rapidly with the volume of information and communication, the supply of attention hardly changes. Markets are a social...

We examine a sample of 125 equity mutual funds that closed to new investment between 1993 and 2004. We find that funds close following a period of superior performance and abnormal fund inflows. Fund managers raise their fees when they close to compensate managers for losses in income due to the...
