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...

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...

Using longitudinal data from the date of arrival, we study long‐term labor market and social insurance outcomes for all major immigrant cohorts to Norway since 1970. Immigrants from high-income countries performed as natives, while labor migrants from low‐income source countries had...

Based on individual longitudinal data, we examine the evolution of employment and earnings of post‐EU accession Eastern European labour immigrants to Norway for a period of up to eight years after entry. We find that the migrants were particularly vulnerable to the negative labour demand shock...

Is there a role for debt beyond curing overaccumulation of capital? Does dynamic efficiency and the infeasibility of debt Ponzi schemes eliminate any Pareto-improving role for a government in a competitive economy with complete markets? Is there an optimal maturity structure of public debt?...

We find that the lifecycle employment profiles of nonwestern male labor migrants who came to Norway in the early 1970s diverge significantly from those of native comparison persons. During the first years after arrival almost all of the immigrants worked and their employment rate exceeded that...
