This paper examines the risks and returns of long-term low-grade bonds for the period 1977-89. The authors find (1) low-grade bonds realized higher returns than higher-grade bonds and lower returns than common stocks, and low-grade bonds exhibited less volatility than higher-grade bonds due to...

This article develops a model of the upstairs market where order size, beliefs, and prices are determined endogenously. We test the model's predictions using unique data for 5,625 equity trades during the period 1985 to 1992 that are known to be upstairs transactions and are identified as either...

The methods of Michael R. Gibbons and Wayne Ferson (1985) are extended, relaxing the assumption that expected returns are linear functions of predetermined instruments. A model of conditional mean-variance spanning generalizes G. Huberman and S. Kandel (1987). The empirical results indicate that...

We investigate whether providers of high frequency news analytics affect the stock market. As identification, we exploit a unique experiment based on differences in news event classifications between different product releases of a major provider of news analytics. We document a causal effect of...

We investigate the cross-sectional relation between dividend yield and expected return and attempt to include various effects of changing risk measure and changing risk premiums. A stock’s risk is measured by its sensitivities to two factors, a market factor and a changing-risk-premium factor....

Tests of asset-pricing models are developed that allow expected risk premiums and market betas to vary over time. These tests exploit the relation between expected excess returns and current market values. Using weekly data for 1963-82 on ten common stock portfolios formed according to equity...
