Over the period 19952006 the Spanish economy experienced a rapid increase in employment and output growth, a surge in investment over GDP, a substantial deterioration in the current account balance and an improvement in the finances of the social security system. This paper presents a dynamic...

We extend previous work that combines the Value at Risk approach with estimation of the correlation pattern of the macroeconomic determinants of public debt dynamics by means of Vector Auto Regressions (VARs). These estimated models are used to compute the probability that the public debt ratio...

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 December 2020 the European Council approved the regulation establishing the European Union (EU) Multiannual Financial Framework for 2021-2027 and the Next Generation EU recovery facility. Both mechanisms will help provide in the coming years for financing worth €1.8 trillion to sustain the...

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...

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...

In this paper we use a large overlapping generations model with individuals that differ across age, productivity and native status to assess the effects on the pension system of different immigration quotas in the context of an aging population by computing how much should social security taxes...

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. The paper...
