Estimates of agents' risk aversion dier between market studies and experimental studies. We demonstrate that the estimates can be reconciled through consistent treatment of agents' tendency for narrow framing, regarding integration of background wealth as well as across risky outcomes: Risk...

The paper investigates the role of the Intertemporal Elasticity of Substitution () in determining the equity premium. This is done in an overlapping generations economy populated by agents that live for 2 periods and maximize a Kihlstrom-Mirman expected utility function. The equity premium...

A major research initiative in finance focuses on the determinants of the cross-sectional and time series properties of asset returns. With that objective in mind, asset pricing models have been developed, starting with the capital asset pricing models of Sharpe (1964), Lintner (1965), and...

In this paper, we examine how learning about disaster risk affects asset pricing in an endowment economy. We extend the literature on rare disasters by allowing for two sources of uncertainty: (1) the lack of historical data results in unknown parameters for the disaster process, and (2) the...

This paper characterizes the solution to a consumption/savings decision problem in which one of the consumption goods involves transaction costs. It then analyzes how such adjustment costs affect consumers' risk attitudes. Previous studies have suggested that transaction costs, by resulting in...

Motivated by the problems of the conventional model in rationalizing market data, we derive the equilibrium interest rate and risk premiums using recursive utility in a continuous-time model. We use the stochastic maximum principle to analyze the model. This method uses forward/backward...

In this paper, another factor that affects equity risk premium is derived from a simple classical monetary model, which basically adds back labor-leisure to a simple consumption-only consumption-based asset pricing model. If every present/future good is traded at time t=0, just as in traditional...

We solve in closed-form a continuous-time Nash equilibrium model in which a finite number of exponential investors continuously consume and trade strategically with price-impact. Compared to the analogous Pareto-efficient equilibrium model, price-impact has an amplification effect on...

The equity premium puzzle holds that the coefficient of relative risk aversion estimated from the consumption based CAPM under power utility is excessively high. Moreover, estimates in the literature vary considerably across countries. We gauge the uncertainty pertaining to the country risk...

The structural uncertainty model with Bayesian learning, advanced by Weitzman (2007), provides a framework for gauging the effect of structural uncertainty on asset prices and risk premiums, and has quite a few appealing attributes. In this paper, we provide an operational version of his...
