Aggregate implications of defined benefit and defined contribution systems
We use a general equilibrium life-cycle model with incomplete markets and heterogeneous agents to evaluate the macroeconomic and welfare implications of Defined Benefit (DB) versus Defined Contribution (DC) systems, and to investigate the effects of incremental reform within a particular system. Extensive calibrations illustrate the trade-off between efficiency and redistribution that a tax-financed, DB social security system generates. We find that social welfare is maximized for small but positive levels of DB because of the redistributive value associated with these systems. On the other hand, steady-state within- DC system comparisons reveal that a zero DC tax rate maximizes social welfare.
