We examine the long-run relationship between fertility, mortality, and incomeusing panel cointegration techniques and the available data for the last century.Our main result is that mortality changes and growth of income per capita account for amajor part of the fertility change characterizing...

I show how the influences of unskilled immigration, differential fertility between immigrants and the local indigenous population, and incentives for investment in human capital combine to predict the decline of the West. In particular, indigenous low-skilled workers lose from unskilled...
