We account for the appreciation of the real exchange rate in Mexico between 1988 and 2002 using a two sector dynamic general equilibrium model of a small open economy with two driving forces: (i) differential productivity growth across sectors and (ii) a decline in the cost of borrowing in...

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...

We analyze the joint impact of employment protection and informality on macroeconomic volatility and the propagation of shocks in emerging economies. For this, we propose a small open economy business cycle model with frictional labor markets, labor regulation, and an informal sector, modeled as...

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...
