The effects of international trade and of international migration have been central to the recent debate on economic integration. Evaluating trade and migration policies is challenging, however, because they often take place at the same time and reinforce each other, making it hard to distinguish their effects. This column uses a general equilibrium approach to quantify the effects of the 2004 EU enlargement. It finds that all EU countries gained from enlargement, but that the largest winners were the new member states, and in particular their low-skilled workers.

Historians and economists generally identify two periods of trade globalisation, the first beginning around 1870 and the second during the 1970s.

If globalisation continues to grow in future, regionalisation may decline.

This column uses the empirical context of Mexico to analyse the economic implications of international and domestic tourism, and the underlying mechanisms. It finds that tourism provides long-run economic gains to households, both at the local level and in the aggregate.
