The paper aims to assess tax-favored retirement accounts in a general-equilibrium overlapping-generations economy with idiosyncratic income risk and borrowing constraints. Our simulations indicate that tax-favored retirement accounts as implemented in many OECD countries will have a significant...

The present paper simulates the privatization 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 as well as borrowing constraints. We compute the transition...

The present paper clarifies the intergenerational welfare effects of life annuities. While present young cohorts experience significant welfare gains, future generations are hurt by lower bequest. For sufficiently high interest rates long-run welfare will decrease although aggregate efficiency...

The present paper focuses on the trade-off between official liquidity provision and debtor moral hazard in sovereign debt problems. The financial crisis is caused by the interaction of bad fundamentals, self-fulfilling runs of private investors and optimal policies of the national government and...

This paper quantitatively characterizes optimal tax systems in a model of overlapping generations, when transitional cohorts are explicitly taken into account. We use the recent study of Conesa et al. (2009) as an example, but extend it by transitional dynamics. We furthermore develop a general...

The present article studies the growth and efficiency consequences of pension funding with individual retirement accounts (IRAs) in a general equilibrium overlapping generations model with idiosyncratic lifespan and labor income uncertainty. We distinguish between economies with rational and...

The present paper quantitatively characterizes the consequences of rising pension progressivity in an overlapping generations model with idiosyncratic income, disability and longevity risk as well as endogenous labor supply at the intensive and extensive margin. Focusing on the German pension...

This chapter examines the micro- and macroeconomic effects of generational policies using closed and open general equilibrium dynamic life-cycle models. The models illustrate the broad array of demographic, economic, and policy issues that can be simultaneously incorporated within today’s...
