Asymmetric information and the demand for private health insurance in Korea

Author

  • Lee, Yong-Woo

Abstract

In this article, we examine the relationship between self-assessed health status, defined as ex-ante health risk, and the demand for private health insurance using data from the Korean Longitudinal Study of Aging. Contrary to theoretical predictions, insurance purchases increase with better health. We present an evidence that this phenomenon may be due to the screening on the part of insurers in the Korean private health insurance market.
