摘要：

In this article, we derive a set of simple conditions such that ambiguity aversion always raises the demand for self-insurance and the insurance coverage, but decreases the demand for self-protection. We also characterise the optimal insurance design under ambiguity aversion and exhibit a case in which the straight deductible contract is optimal as in the expected utility model.
