The paper develops a general equilibrium model where population sources, such as fertility and mortality rates, are chosen variables. It is shown that the evolution of population over time depends on income and relative prices of mortality and fertility rates. Initially as a country develops,...

The paper describes the effects of the non-funded social security systems over fertility rate and labor supply(typically family choice variables). We show that changes on fiscal policy may induce subsequent changes on family choices which produce an endogenous problem of sustainability over the...

This paper explores which large economy blocks determine foreign inflation around the world. In the analysis, we focus on importable goods of 15 countries ranging from 1992 to 2002 at monthly basis. Using a SUR estimation, we find the US driving the inflation of importable goods around the...

We study the relation between inflation rate and relative price variability using data of prices on 23 disaggregated food items since 1960 to 2003 in Chile. The behavior of inflation rate is quite variable in that country during that time span and more interestingly, there are periods of time in...

The paper explores the effects of the social security system over retirement and labor supply decision of individuals aged 55 to 65 in Chile. We use the 1998 CASEN survey elaborated by the Chilean government. Due to regulations established by the current social security law, two social security...

The paper models the behavior of an economy that accumulates capital stock and increases the life expectancy of their inhabitants at the same time. It is shown that as a country develops, it presents initially smaller growth rates on consumption and physical capital but larger expansions on life...

This paper addresses the causes and dynamics of pay-as-you-go social security financial crises. Its main hypothesis is there exists a self-reinforcing vicious circle between the social security system, the fertility rate and labor supply. We argue that changes in the pay-as-you-go social...

This paper deals with the view that income elasticity of health care is larger than one, as argued by empirical results on the literature. We build a theoretical model that shows that endogenous demographic transition may play a fundamental role on this result. It is argued that families must...
