In this paper we study the social, demographic and economic origins of social security. The data for the U.S. and for a cross section of countries make it clear that urbanization and industrialization are strongly associated with the rise of social insurance. We describe a model economy in which...

We use a US Social Security reform as a quasi-experiment to provide evidence on framing effects in retirement behavior. The reform increased the full retirement age (FRA) from 65 to 66 in two month increments per year of birth for cohorts born from 1938 to 1943. We find strong evidence that the...

This paper measures the causal effect of time out of the labor force on subsequent employment of Social Security Disability Insurance (SSDI) applicants and distinguishes it from the discouragement effect of receiving disability benefits. Using a unique Social Security Administration workload...

Most conceptualisations of the bottom billion assume that "the poor" are a minority group in a state of continuous dependency, identifiable by region and demographic. Using a flow analysis (inflow and outflow) of poverty, rather than a stock analysis, we explain why poverty is more appropriately...

We study retirement incentives with augmented option value model à la Stock and Wise (1990). We propose methodological extensions to better reflect the respective incentives faced by singles and couples. Our results show that a more comprehensive modelling of couples' incentives leads to very...

Discrimination in formal labor markets can push discriminated groups into labor informality, where wages are lower and pensions scarce. In this paper, we explore whether education offsets discrimination by empowering discriminated groups to successfully compete for formal jobs. Specifically, we...

We study the labor supply dynamics of elderly couples by means of a structural collective model. The model allows for general externalities with respect to spouses? leisure. Preferences and the intrahousehold bargaining process are identified by using panel data with couples and individuals who...

We develop a general equilibrium stochastic OLG model with heterogenous households. Households differ with respect to their productivity. Productivity depends stochastically on parents' unobservable investment in their child's human capital and an aggregate productivity shock. We introduce a...

This paper analyzes simultaneous voting on the wage tax rate and investment in public education with three overlapping generations and productivity differences inside each cohort. Wage tax revenue finances public education and social security benefits. The presence of productivity differences...

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium...
