The income of many people around the world has considerably increased due to the economic globalization of the last 50 years. However, these income gains are unevenly distributed. In their study, the researchers tried to answer the question if and how the globalization of the last 50 years has affected inequalities between people worldwide.
The result: Globalization has led to greater income inequalities within many countries. The gap between rich and poor has widened particularly in countries that have become more integrated into the global economy, such as China, Russia, and some Eastern European countries. At the same time, globalization has reduced inequality between countries. The differences between countries therefore play an increasingly minor role in the global inequality rate.
