Risk attitudes and private disability insurance holdings

This study identifies several factors that affect the demand for disability insurance (DI), such as wealth, health, financial literacy, and self-reported willingness to take financial risks, using a logit model and a random forest algorithm. While the role of risk aversion in insurance ownership is well established within theoretical insurance models, the empirical literature is still inconclusive. We provide evidence based on the Survey of Consumer Finances that willingness to take financial risks similar to wealth, health, and financial literacy is positively associated with the ownership of private DI. Furthermore, the literature has not explored multivariate risk attitudes in this framework. We thus employ indices of multivariate risk attitudes within a theoretical DI model. Our empirical results on private DI, in conjunction with the theoretical model we present, allow us to test hypotheses regarding multivariate household preferences and reject the hypothesis of correlation-neutral preferences on wealth and health.
