This article examines the experience of cohorts of young American men to se
e how and why their employer-provided health insurance coverage has changed
over time. It explores changes in the structure of the labor market, chang
es in the cost of employer-provided health insurance, and changes in the co
mposition of wages and benefits offered to employees. We find that increase
s in the cost of health insurance rather than changes in the structure of t
he labor market are the principal cause of the observed decline in employer
-provided health insurance coverage across all cohorts.
