Abstract

The Joint Labor Supply Decision of Married Couples and the Social Security Pension System
Shinichi Nishiyama
WP 2010-229

The current U.S. Social Security program redistributes resources from high wage workers to low wage workers and from two-earner couples to one-earner couples. The present paper extends a standard general-equilibrium overlapping-generations model with uninsurable wage shocks to analyze the effect of spousal and survivors benefits on the labor supply of married couples. The heterogeneous-agent model calibrated to the 2009 U.S. economy predicts that removing spousal and survivors benefits would increase female market work hours by 4.3-4.9% and total output by 1.1-1.5% in the long run, depending on the government financing assumption. If the increased tax revenue due to higher economic activity after the policy change was redistributed in a lumpsum manner, a phased-in cohort-by-cohort removal of these benefits would make all current and future age cohorts on average better off.
