Immigration is changing the composition of high income countries. Between 1970 and 2008, the share of foreign born residents in the populations of Britain, the United States, and other rich nations increased from less than 5 percent to over 10 percent, with individuals from low income regions accounting for much of the growth. What objectives guide
current immigration policies in Europe and the US? Are there alternative policies that would raise national welfare in these destinations? Which countries have been most successful in attracting skilled workers as immigrants? In this presentation, Prof. Gordon Hanson reviews the state of play in the global immigration policy debate and examines ideas under consideration for reforming these policies.
