The puzzling evidence of seemingly high momentum returns is related to an understanding of risk as a simple covariance. If we consider, however, risk in higher-order statistical moments, momentum returns appear less advantageous. Thus, a prospect-theoretical assessment of US stock momentum...

Using a new data set on investor sentiment we show that institutional and individual sentiment proxy for smart money and noise trader risk, respectively. First, using bias-adjusted long-horizon regressions, we document that institutional sentiment forecasts stock market returns at intermediate...

In this paper we present a continuous time dynamical model of heterogeneous agents interacting in a financial market where transactions are cleared by a market maker. The market is composed of fundamentalist, trend following and contrarian agents who process information from the market with...

Are the returns accruing to De Bondt and Thaler’s (1985) (DT) much celebrated overreaction anomaly pervasive? Using the CRSP data set used by for the period 1926 through 1982, and, for the first time, an additional two decades of data (1983 through 2003), we provide preliminary support for the...

A derivation of the ICAPM in a very general framework and previous theoretical work, argue for the relative risk aversion (RRA) coefficient to be both time-varying and countercyclical. The variables that represent proxies for the cyclical component of RRA are the market dividend yield, default...

This brief paper constructs a model of delegated portfolio management in which two agency relationships are characterized. First, a delegation process from investors to fund companies, and second, a delegation from fund companies to fund managers. Career concerns of both agents lead to a...

The use of equilibrium models in economics springs from the desire for parsimonious models of economic phenomena that take human reasoning into account. This approach has been the cornerstone of modern economic theory. We explain why this is so, extolling the virtues of equilibrium theory; then...

Episodes of market crashes have fascinated economists for centuries. Although many academics, practitioners and policy makers have studied questions related to collapsing asset price bubbles, there is little consensus yet about their causes and effects. This review and essay evaluates some of...

This paper takes a closer look at the puzzle uncovered by Driesprong et al. (2008) and finds empirical support for the "oil effect" in equity returns. Using forty nine US industry-level returns series and changes in oil spot and future prices, we address whether industry-level returns are...

This article examines whether the overall market risk, along with risks reflecting uncertainty related to the long–run dynamics of market cash flows (dividends) and discount rates (returns), price average returns on single–sorted portfolios in the Greek stock market. Our results...
