We consider long-run behavior of agents assessing risk in terms of dynamic convex risk measures or, equivalently, utility in terms of dynamic variational preferences in an uncertain setting. By virtue of a robust representation, we show that all uncertainty is revealed in the limit and agents...

Almost all important decisions in people’s lives entail risky and delayed consequences. Regardless of whether we make choices involving health, wealth, love or education, almost every choice involves costs and benefits that are uncertain and materialize over time. Because risk and delay often...

Suppose that a group of agents having divergent expectations can share risks efficiently. We examine how this group should behave collectively to manage these risks. We show that the beliefs of the representative agent is in general a function of the group.s wealth level, or equivalently, that...

Typical risk questionnaires aimed at helping advisors guide investors are deficient in five ways. First, each investor has a multitude of risk tolerances, one for each goal and its mental account. Probes for one global risk tolerance miss that multitude. Second, the links between answers to...

In this paper, I examine the decision-theoretic status of risk attitudes. I start by providing evidence showing that the risk attitude concepts do not play a major role in the axiomatic analysis of the classic models of decision-making under risk. This can be interpreted as reflecting the...

This paper analyzes how ambiguity affects the tournament outcome and the project selection of a multi-business-unit organization. We consider a tournament model where business unit managers compete against each other for a promotion reward but are ambiguous about how relatively well their skills...

Understanding how prior outcomes affect risk attitudes is critical for the study of choice under uncertainty. A large literature documents the influence of prior losses on subsequent risk attitudes. The findings appear contradictory: some studies find that people become more risk seeking after a...

Most existing literature examining the links between firm heterogeneity and entry into exporting assumes that firms are risk neutral. In this study, we relax this strict assumption that firms are risk neutral and introduce different attitudes of firms toward risk as an additional source of firm...

We view innovation investment as a real option and explore the implications of ambiguity (Knightian uncertainty) and risk for innovation decisions. Our analysis uses a risk measure and a new outcome-independent measure of ambiguity. We find a consistently significant negative effect of ambiguity...
