I study long-short portfolio strategies formed on seven different stock characteristics representing various measures of past returns, value, and size. Each individual characteristic results in a profitable portfolio strategy, but these single-characteristic strategies are all dominated by a...

We develop a DSGE model in which aggregate shocks induce endogenous movements in risk. The key feature of our model is that households rebalance their financial portfolio allocations infrequently, as they face a fixed cost of transferring cash across accounts. We show that the model can account...

I analyze a model in a simple representative-agent economy with one risky and one riskless asset, populated by habit-forming consumer-investors. These consumer-investors exhibit nonaddictive habit formation in the sense that the current consumption rate of the consumer-investors can fall below...

Researchers have reported mispricing in index options markets. This study further examines the efficiency of the S&P 500 index options market by testing theoretical pricing relationships implied by no-arbitrage conditions. The effect of a traded stock basket, Standard and Poor's Depository...

This paper tests the approach of Madan and Milne (1994) and its extension in Abken, Madan, and Ramamurtie (1996) for pricing contingent claims as elements of a separable Hilbert space. We specialize the Hilbert space basis to the family of Hermite polynomials and test the model on S&P 500 index...

We examine the distribution of returns in new industries to determine whether stocks in new industries are similar to lottery tickets. We focus on one characteristic of lottery tickets: negative expected returns. We examine data from the United States on sellers of own-brand personal computers,...

A change in executive leadership is a significant event in the life of a firm. This study investigates an important consequence of a CEO turnover: a change in equity volatility. We develop three hypotheses about how changes in CEO might affect stock price volatility, and test these hypotheses...

Large swings in stock prices are sometimes associated with a redirection of household savings flows. Such changes can lead to transitory increases in M2 as investors temporarily “park” funds in depository assets while they determine the funds’ ultimate destination. The authors find that,...
