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...

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 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...

In this paper we reflect on the role that fiscal policy could play in the resolution of the crisis in Eurozone countries crippled by both public and private debt, and beset by growth and competitiveness problems. As an illustration, we revisit the Spanish case, a paradigmatic example of the...

This paper builds a large overlapping generations model of a small open economy featuring imperfect competition in the labor and product markets to understand i) which were the main determinants of the large expansionary phase experienced in Spain from the mid-1990s until the arrival of the...

This paper studies how investment and production in an economy is allocated across sectors when they face asymmetric financial conditions. Namely, when investors in one sector may run projects with higher loan-to-values than in another sector. Investors decide where to invest based on total...

Some pieces of empirical evidence suggest that in the U.S., over the last few decades, (i) wage inequality between-plants has risen much more than wage inequality within-plants and (ii) there has been an increase in the segregation of workers by skill into separate plants. This paper presents a...
