Endogenous fringe benefits, compensating wage differentials and older workers

Area of Science:

• Health Economics
• Labor Economics
• Econometrics

Background:

• Employer-sponsored health insurance is a primary source of coverage for Americans under 65.
• Economic theory posits that employees bear the cost of health insurance through reduced wages or compensation.
• Understanding this wage-health insurance trade-off is crucial for labor market analysis.

Purpose of the Study:

• To investigate the empirical relationship between wages and employer-provided health insurance for older U.S. workers.
• To determine the magnitude of the wage adjustment associated with obtaining health insurance.
• To assess the endogeneity of job and insurance choices in this trade-off.

Main Methods:

• Utilized data from the 1994 and 1998 Health and Retirement Survey.
• Employed a two-stage least squares (2SLS) framework to address endogeneity in job and insurance choices.
• Tested the hypothesis that nonwage benefits, such as health insurance, are endogenous.

Main Results:

• Found strong evidence supporting the endogeneity of nonwage benefits.
• The preferred model estimated an annual wage adjustment of $6,300 for health insurance.
• The study noted that the precise magnitude of this trade-off is sensitive to model specification.

Conclusions:

• The findings provide empirical support for the economic theory of the wage-health insurance trade-off.
• Older workers appear to exchange a significant portion of their annual wages for health insurance benefits.
• The fragility of the trade-off's magnitude highlights the complexity of compensation structures and the need for careful econometric modeling.
