We examine asset prices in a representative-agent model of general equilibrium. Assuming only that individuals are risk averse, we determine conditions on the changes in asset risk that are both necessary and sufficient for the asset price to fall. We show that these conditions neither imply,...

This paper calibrates a class of jump-diffusion long-run risks (LRR) models to quantify how well they can jointly explain the equity risk premium and the variance risk premium in the U.S. financial markets, and whether they can generate realistic dynamics of riskneutral and realized...

Empirical measures of world consumption growth risk have failed to rationalize the cross-section of country equity returns. We propose a new factor, termed "the global consumption factor", to explain the patterns in risk premiums on international equity markets. We identify this factor as the...

Most standard asset-pricing models assume that all shocks to consumption are permanent. We relax this assumption and allow also for non-permanent shocks. In our specification, the long-run mean of consumption growth is constant; consumption levels are subject to short-run deviations from their...

We examine the roles of rational and behavioural factors in explaining long-run premiums/discounts on closed-end funds, using evidence on equity funds from the US and UK. Although the processes by which fund prices converge towards long-run premiums or discounts are similar in the two countries,...

This paper investigates how the investors responses to the evolution of uncertainty affect equilibrium asset returns. I develop a discrete-time real endowment economy where the aggregate economic uncertainty, as detected by a time-change for the endowment process, alters the perceived utility...

Prior research has documented the role of information uncertainty in the cross-sectional variation in stock returns. Miller (1977) hypothesizes that if information uncertainty is caused by differences of opinion, prices will reflect only the positive beliefs due to short-sale constraints. These...

We examine the effects of parameter uncertainty and Bayesian learning on equilibrium asset prices when all the structural parameters of the aggregate consumption and dividend growth rate processes are unknown. With realistic calibration of a parsimonious set of prior parameters, the model...
