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...

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...

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...

In this paper we study the quantitative properties of a policy reform aimed at funding the pension system in the standard model economy with perfect substitution across workers with different experience levels and a model economy where this substitutability is imperfect. With compulsory...

The standard argument says that in the presence of positive spillovers foreign direct investment should be promoted and subsidized. In contrast, this paper claims that the very existence of spillovers may require temporarily restricting FDI. Our argument is based on two features of spillovers:...

We propose a new numerical method to solve stochastic models that combines the parameterized expectations (PEA) and the Smolyak algorithms. This method is especially convenient to address problems with occasionally binding constraints (a feature inherited from PEA) and/or a large number of state...
