Using a simple dynamic consumption-based asset pricing model, this paper explores the implications of a representative investor with smooth ambiguity averse preferences [Klibanoff, Marinacci and Mukerji, Econometrica (2005)] and provides a comparative analysis of risk aversion and ambiguity...

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,...

Mean-variance investing is all about diversification. Diversification considers assets holistically and exploits the interaction of assets with each other, rather than viewing assets in isolation. Holding a diversified portfolio allows investors to increase expected returns while reducing risks....

We develop an asset pricing model with external habit formation. The model predicts that the effect of consumption shocks on the equity premium depends on the business cycle. We test this empirical implication using a VAR model of the U.S. postwar economy whose parameters are estimated...

We study dynamic general equilibrium in a Lucas economy with two trees, one consumption good, two CRRA investors with heterogeneous risk aversions, and portfolio constraints. We focus on margin and leverage constraints, which restrict access to credit markets. We find positive relationship...

After taking into account biases induced by infrequent trading and selection, it is unlikely that illiquid asset classes have higher risk-adjusted returns than traditional liquid stock and bond markets. On the other hand, there are significant illiquidity premiums within asset classes. Portfolio...
