Aim: To estimate the price sensitivity of consumer choice of health insurance firm. Method: Using paneldata of the flows of insured betweenpairs of Dutch sickness funds during the period 1993-2002, we estimate the sensitivity of these flows to differences in insurance premium. Results: The price elasticity of residual demand for health insurance was low during the period 1993-2002, confirming earlier findings based on annual changes in market share. We find small but significant elasticities for basic insurance but insignificant elasticities for supplementary insurance. Young enrollees are more price sensitive than older enrollees. Conclusion: Competition was weak in the market for health insurance during the period under study. For the market-based reforms that are currently under way, this implies that measures to promote competition in the health insurance industry may be needed.
