    Description: The present paper aims to quantify the macroeconomic and welfare effects of taxfavored retirement accounts. Starting from an equilibrium without saving incentives, we introduce such accounts and compute the new transition path and the resulting long-run equilibrium. Since our overlapping-generations model comprises a detailed progressive tax system, borrowing constraints as well as stochastic income risk, we can compare macroeconomic and liquidity effects, tax distortions and the insurance properties of the policy reform. Our simulations indicate that tax-favored retirement accounts as implemented in many OECD countries will have a significant impact on capital accumulation and wage growth in the long run, but only yield insignificant aggregate efficiency changes. While elderly generations are typically hurt by such a reform, young and future generations benefit. Finally, with respect to the intragenerational redistribution, a subsidy system that includes direct bonus payments might be preferred to a system with pure tax deductions.

    Description: The present paper studies the role of social security in an economy populated by overlapping generations of individuals that have time-consistent or time-inconsistent preferences, face mortality and individual income risk, borrowing constraints as well as progressive income taxes. Our simulations start from an artificial equilibrium where social security is completely neutral. Next we introduce successively alternative deviations from neutrality in order to isolate the various economic effects of social security. The latter are mainly the insurance provision against mortality and income risk, the negative liquidity effects for young households and the provision of a commitment technology for present-biased hyperbolic consumers. Our simulations indicate that the positive effects of social security dominate the negative ones for a wide range of parameter combinations. For our central parametrization social security induces an overall welfare gain which amounts to roughly 1.5 percent of aggregate resources in the hyperbolic model and a welfare loss of about 0.5 percent of resources in the model with rational consumers.
