六、简介

Highly nonlinear price schemes are commonly used in health insurance contracts, and identifying patients’response to price is an important question for both academia and policymakers. Although the literature has well established that both the current cost sharing (“spot price”) and expected end-of-year price (“future price”) matter when making dynamic decisions, little empirical work has been conducted to explain to what extent the two prices matter or which price matters more. In this study, we answer this question by quantifying patients' response elasticity to both spot price change and future price change in the same group of people under a health care insurance scheme in China. Specifically, we exploit two natural experiments in the same health insurance scheme. The first experiment contains a change in the spot price only and the second contains changes in both the spot price and future price. Our analysis suggests an elasticity to the spot price of 0.09~0.14 and to the future price of 0.92~1.01, which demonstrates the importance of the future price. This paper contributes to the literature by serving as one of the first empirical efforts to derive multiple elasticities in health insurance and deliver policy implications for health insurance contract design.
