We study the aggregate effects of a social security reform in a large overlapping generations model where markets are incomplete and households face uninsurable idiosyncratic income shocks. We depart from the previous literature by assuming that, because of lack of commitment in the credit...

We study the evolution of the distribution of assets in a deterministic version of the Neoclassical Growth Model with log-utility, a minimum consumption requirement, and Cobb-Douglas technology. Agents are heterogeneous in their initial endowment of assets only. The dynamics of the aggregate...

We study the evolution of the distribution of assets in a discrete time, deterministic growth model with log-utility, a minimum consumption requirement, Cobb-Douglas technology, and agents differing in initial assets. We prove that the coefficient of variation in assets across agents decreases...

We study the aggregate effects of a social security reform in a large overlapping generations model where markets are incomplete and households face uninsurable idiosyncratic income shocks. We depart from the previous literature by assuming that, because of lack of commitment in the credit...

In this paper we study the quantitative properties of alternative social security regimes in a large overlapping generations model where households face uninsurable idiosyncratic income shocks. We study this issue in two model economies. The first is the standard one characterized by exogenous...

We study the effects of a social security reform in a large overlapping generations model where markets are incomplete and households face uninsurable idiosyncratic income shocks. We depart from the previous literature by assuming that, because of lack of commitment in the credit market, the...

Recent empirical studies show that the intergenerational persistence of income is much higher than previously thought. The objective of the paper is to account for this observation. Unlike models that rely on exogenous transmission of abilities or luck, we generate persistence endogenously...

Recent empirical studies show that the intergenerational persistence of economic status in the U.S. is much higher than previously thought. We develop a quantitative theory of inequality and intergenerational transmission of human capital where parents invest in early and college education of...

We study the aggregate effects of a social security reform in a large overlapping generations model where markets are incomplete and households face uninsurable idiosyncratic income shocks. We depart from the previous literature by assuming that, because of lack of commitment in the credit...

We build a small open economy, real business cycle model with labor market frictions to evaluate the role of employment protection in shaping business cycles in emerging economies. The model features matching frictions and an endogenous selection effect by which inefficient jobs are destroyed in...
