This paper proposes a dynamic risk-based model that captures the high expected returns on value stocks relative to growth stocks, and the failure of the capital asset pricing model to explain these expected returns. To model the difference between value and growth stocks, we introduce a...

Among the most important pieces of empirical evidence against the standard representative agent, consumption-based asset pricing paradigm are the formidable unconditional Euler equation errors the model produces for cross-sections of asset returns. Here we ask whether calibrated leading asset...

We develop a consumption-based present value relation that is a function of future dividend growth. Using data on aggregate consumption and measures of the dividend payments from aggregate wealth, we show that changing forecasts of dividend growth make an important contribution to fluctuations...

This paper demonstrates that the optimal willingness to pay for a stock is the payoff from holding the stock for one period when investors have different expectations, and that the willingness to pay can be represented as the sum of the expected present value of future dividends and the expected...

This paper extends the Harrison-Kreps model by allowing limited short sales. The main results of this paper are: (1) investors pursue short-term gains when perceiving heterogeneous expectations; (2) important properties of the equilibrium price in the Harrison-Kreps model still hold even when...

Dans cet article, pour etendre la theorie du consommateur a ses choix d'epargne et de placements, on utilise a la fois la theorie usuelle, celle des caracteristiques et celle du raisonnement quantitatif. On en deduit un systeme complet de demandes comprenant simultanement les quantites de biens...

This paper prepared for the Handbook of Statistics (Vol.14: "Statistical Methods in Finance"), surveys the subject of stochastic volatility. the following subjects are covered: volatility in financial markets (instantaneous volatility of asset returns, implied volatilities in option prices and...

A front page Sunday New York Times article on a potential development of new drugs to cure cancer caused the price of EntreMed (ENMD) stock to rise from 12.063 at the Friday close, to open at 85 and close near 52 on Monday. Trading volume was more than 400 times the normal trading volume, and...

In June 1997, the Nasdaq stock market and the New York Stock Exchange (NYSE) each lowered its minimum price increment on most stocks from eighths to sixteenths. Like other researchers investigating similar events, we find that quoted spreads and effective spreads decline on both markets with the...

This paper derives a negative relationship between the dispersion of forecasts among investors and future stock returns based on Harrison and Kreps (1978). Using monthly data for earnings forecasts by market analysts, this paper presents empirically that the dispersion in forecasts has...
