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...

The goal of this paper is to determine the effects of different social security regimes on job search. A less generous pension system induces higher savings across the life cycle and makes agents wealthier and thus more reluctant to accept low wage offers. On the other hand, as the social...

In contrast to the standard literature, we show that the presence of spillovers may justify temporarily restricting the inflow of foreign direct investment. Our argument is based on two stylized features of spillovers: first, technology transfers --- and subsequent spillovers --- are limited by...

Abstract: This paper uses an overlapping generations model with endogenous fertility choices to analyze the quantitative costs and benefits of subsidizing higher education, paying particular attention to the interaction between such policy and the sustainability of the social security system....

In this paper we survey the features of different approaches available in the literature used to study the effects of the aging of the population on Social Security expenditures. We comment on the weaknesses and strengths of each of them, and perform a quantitative analysis by comparing the...

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...

This paper presents a dynamic general equilibrium model designed to compute the aggregate impact of immigration, accounting for relevant supply and demand effects. We calibrate the model to the Spanish economy, allowing for enough heterogeneity in the demographic characteristics of immigrant and...
