Abstract Text The economic literature on the demand for non-life insurance has mainly emphasized the influence of risk aversion. Under the assumption of decreasing absolute risk aversion, it has been shown that insurance should be an inferior good. Under the assumption of increasing relative risk aversion, it has been shown that the wealth elasticity of insurance should exceed one. These seemingly contradictory propositions are due to strong implicit assumptions about changes in the composition of wealth. The present paper proposes a more general model where the effects of risk aversion and of the composition of wealth are considered jointly. Necessary and sufficient conditions for a decrease in the willingness-to-insure are defined, and their implications for the interpretation of empirical results on insurance spending and risk-averse behavior are pointed out.
