Abstract

This paper presents an empirical analysis of the determinants of quantity of health insurance in the context of employer-based health insurance using the micro-level data from the 1987 National Medical Expenditure Survey (NMES). It extends the previous research by including additional factors in the analysis, which significantly affect health insurance offers by employers. This paper emphasizes two determinants of employers’ insurance offer decisions that are particularly relevant: union membership and selfinsured versus not self-insured health plans. The conducted empirical analysis reported in this paper reveals the following predictors of higher health insurance coverage: union membership, not self-insured health plan(s), union membership in Midwest or South, as well as self-insured union membership. Further, other factors such as: age, male, income, for profit and other employer organizational forms, and firm’s size determine a higher level of health insurance.
