This paper studies human-capital formation, labor-supply, and retirement decisions associated with four alternative regimes of social security. We implement a theoretical model with overlapping generations of households and two different ability types within each generation. We find that with a...

We study the reform of the Spanish public pension system in a multiperiod, general equilibrium, overlapping generations model economy populated by heterogeneous households. Our households differ in their place of birth, in their age, in their education and, endogenously, in their employment...

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...

We analyze two social security reforms aimed at increasing working lifetimes. The rst reform elim- inates early retirement provisions, while the second increases both the age of early eligibility and the normal retirement age. We nd that although both reforms increase the participation rates of...

Ýmrohoroðlu, Ýmrohoroðlu and Joines [1995, A life-cycle analysis of Social Security, Economic Theory, vol. 6, 83-114] show that the optimal replacement ratio of the payas-you-go public pension system in the US economy amounts to 30%. We extend their analysis to a model that 1) replicates the...

We study the welfare effects of earnings testing flat-rate old-age benefits in a quantitative overlapping generations model with idiosyncratic labor income risk. In our model economy, even a moderate earnings testing reduces individualsŽ expected lifetime utility. Moreover, it also lowers the...

The objective of this paper is to analyze the welfare effects of raising the retirement age. With aging populations, in many countries de iure retirement age has been raised. With a standard assumption that individuals prefer leisure to work, such policy necessitates some welfare deterioration....
