Does corporate diversification reduce shareholder value? Since firms endogenously choose to diversify, exogenous variation in diversification is necessary in order to draw inferences about the causal effect. We examine changes in the within-firm dispersion of industry investment, or diversity.'...

Diversified firms have different values than comparable portfolios of single-segment firms. These value differences must be due to differences in either future cash flows or future returns. Expected security returns on diversified firms vary systematically with relative value. Discount firms...

We test whether the impact of financial constraints on firm value is observable in assetquot; returns. We form portfolios of firms based on observable characteristics related to financialquot; constraints, and test for common covariation in the stock returns of these firms. Using severalquot;...

Capital expenditure plans at the beginning of the year, from a US government survey of firms, explain more than three quarters of the variation in real annual aggregate investment growth between 1948 and 1993. The negative correlation of contemporaneous investment and stock returns is explained...

This paper examines micro data on U.S. firms' inventories during different macroeconomic episodes. Much of the analysis focuses on the 1981-82 recession, a recession that was apparently precipitated by tight monetary policy. We find important cross-sectional effects in this period: firms that...

We test whether the time-series positive correlation of inflation and intermarket relative price variability is also present in a cross-section of US cities. We find this correlation to be a robust empirical regularity: cities which have higher than average inflation also have higher than...

In this paper, we use city-level data to analyze the relationship between homeowner borrowing patterns and house-price dynamics. Our principal finding is that in cities where homeowners are more leveraged--i.e., have higher loan-to-value ratios--house prices react more sensitively to...

I study battles between short sellers and firms. Firms use a variety of methods to impede short selling, including legal threats, investigations, lawsuits, and various technical actions intended to create a short squeeze. These actions create short sale constraints. Consistent with the...

We examine some basic data on the evolution of aggregate short interest, both during the dot-com era, and at other times in history. Total short interest moves in a countercyclical fashion. For example, short interest in NASDAQ stocks actually declines as the NASDAQ index approaches its peak....

Corporate events, such as new issues and new lists, appear in waves. These waves imply that the market portfolio has a time-varying weight in new lists, and one can decompose the market return into a fixed weight return plus a timing return. Most of the reduction in aggregate market returns...
