The Effect Of Income Taxation On Consumption And Labor Supply, James P. Ziliak, Thomas J. Kniesner

Center for Policy Research

We estimate the incentive effects of income taxation in a life-cycle model of consumption and labor supply that relaxes the standard assumption of strong separability within periods. Our model permits identification of both within-period preference parameters and lifecycle preference parameters such as the inter-temporal substitution elasticity. Results indicate that consumption and hours worked are direct complements in utility, and both increase with an increase in the after-tax share and with a compensated increase in the net wage. The compensated net wage elasticity is about 0.3, nearly double the standard estimates for men in the United States that ignore within-period non-separability …
