The latest edition of the Economic Journal contains new research by Paolo Epifani and Gino Gancia that focuses on the skills preium for highly skilled workers in an age of globalisation. Whilst increasing economic integration between countries has undoubtedly contributed to a process of income convergence across nations, one of the paradoxes it that it can also lead to greater pay and earnings inequalities within countries - this research helps to explain why.

“Since the mid-1970s, the wage gap between high-skilled and low-skilled workers has widened. At the same time, world trade has increased dramatically: between 1980 and the late 1990s, the share of countries ‘open to trade’ rose from 35% to 95%, and the volume of trade of the average country rose from 59% of national income to 74%....Globalisation increases the size of the market firms can access. Some industries can take advantage of a larger market more easily than others as they benefit from ‘economies of scale’.The study argues that those industries that take advantage of a larger market are more likely to employ skilled workers, and so the wages of skilled workers will rise faster than unskilled workers in a period of globalisation.”
