Behavioral foundations of the substitutability between insurance and self-insurance: An experimental study

In this experimental study, the analysis on two levels of substitution between insurance and self-insurance shows that a higher unit price results in a quantity-based substitution and a between-tools substitution while the only effect of a higher fixed cost is to reduce the insurance market. The optimality of the coverage demands associated with the equalization of marginal returns is not achieved. Instead, individuals chose a stable global amount of coverage. These behavioral insights have a potential impact on public policies related to insurance and self-insurance.
