We provide a new foundation of risk aversion by showing that the propension to exploit insurance opportunities fully describes this attitude. Our foundation, which applies to any probabilistically sophisticated preference, well accords with the commonly held prudential interpretation of risk aversion that dates back to the seminal works of Arrow (1963) and Pratt (1964). In our main results, we first characterize the Arrow-Pratt risk aversion in terms of propension to full insurance and the stronger notion of risk aversion of Rothschild and Stiglitz (1970) in terms of propension to partial insurance. We then extend the analysis to comparative risk aversion by showing that the notion of Yaari (1969) corresponds to com- parative propension to full insurance, while the stronger notion of Ross (1981) corresponds to comparative propension to partial insurance.
