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...

Between 1988 and 2002, the real exchange rate in Mexico appreciated by 45%. We account for this movement in relative prices using a two sector, dynamic general equilibrium model of a small open economy with tradable an non-tradable goods. The model allows us to identify the effect of the...

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...

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 build a partial equilibrium model of firm dynamics under exchange rate uncertainty. Firms face idiosyncratic productivity shocks and observe the current level of the real exchange rate each period. Given their current level of capital stock, firms make their export decisions and choose how...
