This paper investigates robust consumption and portfolio rules for an Epstein-Zin type investor who concerns about model misspecifiation. Different from Maenhout (2004), we employ a new state variable, continuation entropy, as a measure of the magnitude of the investor's ambiguity aversion...

Models of optimal retirement should reflect market incompleteness in reality caused by disability risk. In this paper, we develop an analytic approach for optimal retirement models with disability risk. More precisely, we provide an analytically tractable characterization of total wealth that is...

We find robust portfolio rules for ambiguity-averse fund managers in a financial market with proportional transaction costs. The model proposed in this paper permits a liquidity premium much bigger than those found by most empirical literature. Our liquidity premium is much bigger when using...

Dissemination of information can enhance smallholder farmers’ agricultural outcomes and incomes in developing countries. However, the impact evaluation for new information can be inaccurate without considering pre-existing information that the indigenous people have used. This study explores...

This study estimates the random utility function of fluid milk using 1,165 survey responses in Laos. It finds that both products' attributes and individual characteristics affect consumers' preference for the milk and the hypothetical brand of Laos-Korea has a potential compared to four real...

In this paper we generalize the following result of McDonald and Siegel (1986) on optimal investment: it is optimal for an investor to invest when project cash flows exceed a certain threshold. We have other results that refine or extend the result of McDonald and Siegel (1986) by integrating...

This study aims to generalize the following result of McDonald and Siegel (1986) on optimal investment: it is optimal for an investor to invest when project cash flows exceed a certain threshold. This study presents other results that refine or extend this one by integrating timing flexibility...
