Spillover of cause-specific longevity interventions: an independent mortality risk model

As an alternative to the "competing mortality risk model", this paper presents an "independent mortality risk model" in which the complementarity among various longevity investments is less obvious. In studying spillover effects of cause-specific longevity interventions, it distinguishes between two types of such interventions: cause-specific price reductions and cause-specific direct provisions. It finds that a cause-specific direct provision always has a positive spillover effect on longevity investments for other causes, but a cause-specific price reduction may have a negative spillover effect due to a substitution effect.
