I investigate whether the popular Krusell and Smith algorithm used to solve heterogeneousagent economies with aggregate uncertainty and incomplete markets is likely to be subject to multiple self-fulfilling equilibria. In a benchmark economy, the parameters representing the equilibrium aggregate...

This note shows that the loss deviations in Selten's (1995) risk dominance measure are the same as the arguments of the probability of a strategy that supports a sequential equilibrium. Risk dominance is used to select among Nash equilibria, while sequential equilibrium, which is stronger than...

This paper investigates the effect of inflation uncertainty on the portfolio behavior of households and the equilibrium structure of capitol market rates. The principal findings regarding portfolio behavior are: (1.) In the presence of inflation uncertainty, households will have an...

We study consumption-portfolio and asset pricing frameworks with recursive preferences and unspanned risk. We show that in both cases, portfolio choice and asset pricing, the value function of the investor/representative agent can be characterized by a specific semilinear partial differential...

In this paper, we document evidence that downside betas tend to comove more than upside betas during a financial crisis, but upside betas tend to comove more than the downside betas during financial booms. We find that the asymmetry between Downside-Beta Comovement and Upside-Beta Comovement is...

Our paper analyzes the performance of different methods to adjust beta. Specifically, we compare the standard OLS regression method with the Blume and the t-distribution methods from the point of view of reference-day risk. Our results indicate that the t-distribution method minimizes the...

This study investigates the impact of uncertainty on the mean-variance relationship. We find that the stock market’s expected excess return is positively related to the market’s conditional variances and implied variance during low uncertainty periods but unrelated or negatively related to...

Uncertainty is known to be crucial in asset pricing, yet evidence from comprehensive analysis of various uncertainty measures remains sparse. This paper investigates the predictability of stock returns based on economic fundamentals uncertainty by constructing a novel uncertainty index derived...
