It may be in the interest of low-ability individuals to subsidize the education of high-ability individuals. Sufficient conditions are surprisingly mild: positive externalities in education and complementarity in production between human capital and labor supplied by the low-ability individuals....

While the effect of social security systems on retirement decisions has received much attention, the impact of these systems on individuals' incentives to invest in their human capital has not been analyzed. We integrate human capital investment and retirement decisions in a simple analytical...

We consider taxation by a Leviathan government and by a utilitarian government in the presence of heterogenous locations within a country, when migration from one country to another is and is not possible. In a closed economy, a utilitarian government may transfer income from the poor to the...

We propose a dynamic general equilibrium model with human capital accumulation to evaluate the economic consequences of compulsory services (such as military draft or social services). Our analysis identifies a so far ignored dynamic cost arising from distortions in time allocation over the...

In earlier literature, the suggested Pareto improvements in pay-as-you-go (PAYG) systems have relied on the presence of externalities or the possibility of intragenerational redistribution. We show that neither assumption is necessary in an economy with intergenerational trade in a fixed factor...

Corporate success often resembles a snowball. We show how initial luck in hiring talented people, the resulting technological advantage, superior corporate culture, and status-seeking by workers can make small initial differences generate large differences over time.

Government-run entities are often more labor-intensive than private companies, even with identical production technologies. This need not imply slack in the public sector, but may be a rational response to its wage tax advantage over private firms. A tax-favored treatment of public production...
