On the Redistributive Power of Pensions
Résumé
We study the tradeoff between efficiency and redistribution in a model with overlapping generations, extensive labor supply, and perfect financial markets. The government instruments are a pension scheme and a age-independent nonlinear income tax schedule. At the second-best optimum, the pension system constrains the agents’ labor supply behavior, forcing them to work to achieve a required lifetime performance. Income taxes affect labor supply directly, but also indirectly through pension incentives. The indirect effect of taxes counteracts the usual forces in the efficiency-redistribution tradeoff: through the interplay with the pension system, decreasing taxes induces redistribution and reduces productive efficiency.
