Are tax subsidies for private medical insurance self-financing? Evidence from a microsimulation model for outpatient and inpatient episodes

Abstract

This paper develops an empirical strategy to estimate whether subsidies to private medical insurance are self-financing in countries where public and private health insurance coexist. We construct a simulation routine based on a micro econometric discrete choice model that allows us to evaluate the impact of premium changes on the utilisation of outpatient and inpatient health care services. As an application, we simulate the main feature of the 1999 Spanish income tax reform that abolished the individual tax deduction for expenditures on private health insurance. We find evidence suggesting that the fiscal subsidy is far from self-financing. This result is driven by the fact that private medical insurance holders make concurrent use of public services and by the low price elasticity of the demand for policies.
