Estimating Life Cycle Labor Supply Tax Effects
Posted: 9 Mar 1999
We present an econometrically tractable life cycle labor supply model for panel data including intertemporally progressive taxes on uncertain wage and nonwage incomes. Our two-stage fixed-effects generalized method-of-moments approach first estimates intratemporal and then intertemporal preferences. Specification testing demonstrates the value of incorporating joint progressive taxation of labor and nonlabor incomes. Results for prime-age men emphasize the roles played by hourly wage endogeneity, worker-specific effects, the measure of the rate of pay, and intertemporal budget constraint nonseparability. Simulations indicate that recent tax reforms, while not self-financing, stimulated male labor supplied by about 3 percent and reduced deadweight loss by about 16 percent.
