We investigate the dynamics of prices, information and expectations in a competitive, noisy, dynamic asset pricing equilibrium model. We show that prices are farther away from (closer to) fundamentals compared with average expectations if and only if traders over- (under-) rely on public...

The Fama-French factors are ubiquitous in empirical finance, industry, and law. We find that factor returns differ substantially depending on when the data were downloaded. The effects of these retroactive changes are large. Holding the sample period constant and varying only factor vintages, we...

This paper shows that, in the canonical dynamic rational expectations equilibrium model, public information about future noise trading is potentially detrimental to contemporaneous price efficiency. Our result supports concerns that social sentiment investing, sparked by growing availability of...

The arrival of new, unfamiliar, investment opportunities is often associated with "exuberant" movements in asset prices and real economic activity. During these episodes of high uncertainty, financial markets look at the real sector for signals about the profitability of the new investment...

Lower skill of the active management industry can imply greater fee revenue, value added, and investor performance. Such outcomes arise in a competitive equilibrium in which portfolio choices of active managers partially echo those of noise traders and also contain manager-specific noise. Both...

This study shows that fitting errors of equity-option-implied volatility surfaces are informative about intermediary frictions. For each stock and day, we quantify the goodness of fit between the observed implied volatilities of all available options and the corresponding estimates from...

We examine the cross-sectional determinants of individual investors´ noise trading activity based on their respective Big Five personality traits. Our unique data set is obtained by a self-reported questionnaire that includes responses of 2,147 individual investors who actively engage in...

Contributing to the debate on the nominal price puzzle, we show that higher stock price level is associated with lower noise trading level which confirms Black's (1986) conjectures that noise traders prefer low-priced stocks to high-priced stocks. The result is robust after controlling for...

The existence of the pricing kernel is shown to imply the existence of an ambient information process that generates market filtration. This information process consists of a signal component concerning the value of the random variable X that might be interpreted as the timing of future cash...
