**报告摘要：**

Yaari's dual theory of choice under risk is the natural counterpart of expected utility theory. While optimal payoff choice for an expected utility maximizer is well studied in the literature, less is known about the optimal payofffor a Yaari investor. We perform a fairly general analysis and derive optimal payoffs in a variety of relevant cases. Specifically, we provide the optimal payoff for a Yaari investor under a variance constraint; thus, extending mean-variance optimization to distorted expectation-variance optimization. We also provide the optimal payoff for Yaari investors who aim to outperform an external benchmark.
