This note demonstrates that optimal tax calculations in overlapping generations models should not be based exclusively on long-run welfare changes. As the latter represent a mix of efficiency and intergenerational redistribution effects, they typically favor policies which redistribute towards...

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...

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 paper analyzes the recent pension reform in Germany which increases the normal retirement age by two years. The applied simulation model features a realistic demographic transition, distinguishes three skill classes with different life expectancies and allows individuals to choose their...

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 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...

The present paper quantifies the economic consequences of eliminating the system of income splitting in Germany. We apply a dynamic simulation model with overlapping generations where single and married agents have to decide on labor supply and homework facing income and lifespan risk. The...

The present paper aims to quantify the growth and welfare consequences of changing family structures in western societies. For this reason we develop a dynamic general equilibrium model with both genders which takes into account changes of the marital status as a stochastic process. Individuals...

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