Gary Becker writes about the recent WEO , chapter on Globalization and Inequality by IMF;
Is this greater gap between the earnings of more and less skilled workers a good or bad result of globalization? Let us accept that greater inequality is not good, other things the same, but other things are different in the IMF results on inequality. The increased earnings gap between persons with more and less education in developing countries reflects that the earnings of more educated individuals rose faster than the earnings of the less educated. The IMF report clearly shows that generally the poorer and less educated in developing nations also became better off in that they have more to spend on food, shelter, health, automobiles, and the other goods that they desire. This improvement in wellbeing at the lower end of the income distribution surely should count as a benefit of globalization.
The larger earnings gap by education essentially means that the returns on investments in schooling increased. Few critics of globalization would claim that its effects were bad if globalization significantly raised the returns to financial or physical capital owned by local investors in developing countries. So how can one complain that globalization is bad because it raises the returns on the education of local human capital investors? Higher returns to human capital investments as well as greater returns to plant and equipment mean that the economy is more productive, which should be a welcome development to poorer as well as richer countries.
Yet intellectuals and politicians in many countries of Latin America, Africa, and even parts of Asia have heavily criticized globalization and its effects. I believe that developing countries in which the criticisms are strongest are generally countries that have done a bad job of educating its population. Higher returns on investments in education and other human capital are small comfort to the children of poor families who often do not have easy access to secondary schools, let alone to universities and other forms of advanced investments in human capital. The lesson of the IMF report and other studies is that globalization is not the source of these serious problems. Rather, the lesson is that many developing countries have to do much more to open up access to better and greater education for children coming from lower income families. Only then would these families be able to take advantage of the higher returns to education produced by greater trade and the inflow into their economies of modern technologies and foreign capital.
