We have analyzed the determinants of the Gini coefficient for income and expenditure. In both cases, we do not find support for the Kuznets inverted-U hypothesis. From economic globalization viewpoint, the opening of goods markets reduces income inequality both in the short run (the Gini coefficient for income) and in the long run (the Gini coefficient for expenditure). On the other hand, the opening of capital markets increases income inequality both in the short and long run, but the latter is not statistically significant. These results suggest that the effect of economic globalization has two routes and two different speeds to affect income inequality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
