Does globalization, as its advocates maintain, help spread the wealth? Or, as its critics charge, does globalization hurt the poor? In a new book titled Globalization and Poverty, edited by NBER Research Associate Ann Harrison, 15 economists consider these and other questions. In Globalization and Poverty (NBER Working Paper No. 12347), Harrison summarizes many of the findings in the book. Her central conclusion is that the poor will indeed benefit from globalization if the appropriate complementary policies and institutions are in place.
Harrison first notes that most of the evidence on the links between globalization and poverty is indirect. To be sure, as developing countries have become increasingly integrated into the world trading system over the past 20 years, world poverty rates have steadily fallen. Yet little evidence exists to show a clear-cut cause-and-effect relationship between these two phenomena.
Many of the studies in Globalization and Poverty in fact suggest that globalization has been associated with rising inequality, and that the poor do not always share in the gains from trade. Other themes emerge from the book. One is that the poor in countries with an abundance of unskilled labor do not always gain from trade reform. Another is that the poor are more likely to share in the gains from globalization when workers enjoy maximum mobility, especially from contracting economic sectors into expanding sectors (India and Colombia). Gains likewise arise when poor farmers have access to credit and technical know-how (Zambia), when poor farmers have such social safety nets as income support (Mexico) and when food aid is well targeted (Ethiopia).
