We study the implications of differential fertility on cross-sectional inequality in a canonical model of the intergenerational transmission of capital. Our main theoretical result shows that, with differential fertility, there exist stable atomless steady state distributions of capital where...

Tradable permits are now widely used to control pollution. We investigate the implications of setting up such a system in another area – population control – either domestically or at the global level. We first generalize the framework with both tradable procreation allowances and tradable...

The demographic problems in developed countries are getting more and more important. Very low fertility rates especially among skilled individuals will soon become relevant for a country's economy. Also of importance is education of children. Since there is an increasing demand for skilled...

We theoretically analyze the effects of a child allowance, an improvement in the efficiency of child rearing and a labor income tax on the fertility rate and per capita consumption. The effects on per capita consumption are opposite in the absence, and the presence, of unemployment. For example,...

In this paper, we analyze the extent to which market forces create an incentive for cloning human beings. We show that a market for cloning arises if a large enough fraction of the clone?s income can be appropriated by its model. Only people with the highest ability are cloned, while people at...
