2. ESL International Conference, UCL, Louvain-la-Neuve Andrew Mountford The Evolution of the World Distribution of Income Depends on both on the growth of income per capita and the growth of population across countries A large literature on the determinants of differences in the rate of growth of income per capita, Smaller literature on relationship between differential fertility rates and economic growth - with Galor and Weil (1999, 2000) Galor and Moav (2002), Kremer and Chen (2002). De la Croix and Doepke (2003, 2004, 2006) and Moav (2005) being notable exceptions. Contribution of this paper is to analyse the effect of skilled migration on both economic growth and fertility. Emphasis is on international influences and is thus related to Galor and Mountford (2005).

9. ESL International Conference, UCL, Louvain-la-Neuve Andrew Mountford Do Fertility and Human Capital Accumulation Respond to Skilled Migration? Here we present (Very Preliminary) empirical evidence that shows that Brain Drain propensity Reduces Fertility in sending economies Increases primary education in sending economies but on average reduces higher education

20. ESL International Conference, UCL, Louvain-la-Neuve Andrew Mountford Theoretical Model Designed to Answers the Questions Why do economies with low levels of skilled labor and high levels of fertility send skilled workers to economies with a higher levels of skilled labor and low fertility? Is the phenomenon of Brain Drain emigration likely to be a transitory or a permanent feature of the world economy? Will this Brain Drain migration increase the rate of economic growth in the receiving economies? And in the sending economies? Will the Brain Drain promote convergence or divergence in the world distribution of income? Should the sending or receiving economies try to stop or limit this flow of people?

21. ESL International Conference, UCL, Louvain-la-Neuve Andrew Mountford Theoretical Model OLG Model based on Galor and Moav (2000) extended to include fertility decisions and migration Agents make optimal fertility and human capital accumulation decisions Central idea is that the rate of growth of technology is skilled biased while the level of technology is neutral International diffusion of technology is regarded as a level effect and is thus is not skill biased

47. ESL International Conference, UCL, Louvain-la-Neuve Andrew Mountford Conclusions Even if there is convergence or stability in the world distribution of income per capita there are good reasons for believing that the world distribution of income will diverge due differences in population growth between rich and poor economies The current trend towards skilled migration from poor to rich economies increases the potential for divergence
