This paper analyzes the dynamic politico-economic equilibrium of a model where repeated voting on social security and the evolution of household characteristics in general equilibrium are mutually affected over time. In particular, we incorporate within-cohort heterogeneity in a two-period...

Even though smokers incur higher health expenditures than nonsmokers of the same age, smokers have significantly higher mortality rates, so the expected lifetime health expenditure for a smoker is actually lower than for a nonsmoker. Because of this fact, some politicians and policy-makers have...

Sweden's distribution of disposable income is very even, with a Gini coefficient of just 0.31. Yet, the wealth distribution is extremely unequal, with a Gini coefficient of 0.79. Moreover, Swedish wealth inequality is to a very large extent driven by the large fraction of households with zero or...

This paper develops an overlapping agents model with age-specific mortality rates. The analytical framework also nests Blanchard's (1985, Journal of Political Economy 82, 1095–1117) "perpetual youth" model as a special, though perhaps not realistic, case. With age specific mortality...

The worldwide problem with pay-as-you-go, defined-benefits social security systems isn't just financial. Through a dynamic, overlapping-generations model where forming a family and bearing and educating children are choice variables, we show that social security taxes and benefits generate...

We explore the quantitative implications of uncertainty about the length of life and a lack of annuity markets for life cycle consumption in a general equilibrium overlapping generations model in which markets are otherwise complete. Empirical studies find that consumption displays a hump shape...
