摘要：this paper provides the first piece of empirical evidence regarding the impact of health cost risk on individuals’ annuitization decisions. we find that health cost risk increases the probability of individuals’ pension participation but decreases the amount of pension contributions. we show that the substitution effect of informal insurance on pensions leads to these seemingly contradictory results. the impact of health cost risk on pension participation and contributions is negative and consistent with the mainstream theory after accounting for the effect of informal insurance. the substitution effect of informal insurance on pensions is stronger, and thus mitigates the impact of health cost risk more pronounced for households that have better-educated children, lower incomes, and more informal social networks and in regions that have a higher male–female ratio, that have higher mobility, or are less developed; but this substitution effect does not differ depending on their children’s gender. this study improves our understanding of the relationship between health cost risk and individuals’ annuitization decisions as well as the role of informal insurance in this relationship.
