In this Paper we develop a model of intertemporal portfolio choice where an investor accounts explicitly for the possibility of model misspecification. This work is motivated by the difficulty in estimating precisely the probability law for asset returns. Our contribution is to develop a...

In this paper, we show how an investor can incorporate uncertainty about expected returns when choosing a mean-variance optimal portfolio. In contrast to the Bayesian approach to estimation error, where there is only a single prior and the investor is neutral to uncertainty, we consider the case...

Economic theory suggests that uninsurable income risk, health risk and the expectation of future borrowing constraints can reduce the share of risky assets in a household's portfolio. In fact, if its utility function exhibits decreasing absolute risk aversion and decreasing prudence, a household...

Absent much theory, empirical works often rely on the following informal reasoning when looking for evidence of a mutual fund tournament: If there is a tournament, interim winners have incentives to decrease their portfolio volatility as they attempt to protect their lead, while interim losers...

We study the relation between gender and stock holdings in Finland, a particularly gender equal country. We show that it is crucial to control for risk aversion using a measure of subjective risk-taking, rather than measures derived from abstract gambles. Controls related to financial knowledge...

This paper studies a Lucas (1978) fruit-tree economy under the assumption that the agents are Choquet expected utility (CEU) rather than standard expected utility decision makers. More specifically, the agents' non-additive beliefs about the economy's dividend payment process are modeled as...

Several investment decisions deal with non-marketable assets. Non-marketable assets are available only to one investor and are often indivisible. This has relevant consequences on investor investment opportunities. Adhering to a mean–variance representation of the investment space and...
