Globalization and inequality
The Economist has a nice little essay on the relationship between globalization and worldwide income inequality ("Catching Up. If You Consider People, Not Countries, Global Inequality is falling rapidly") - summarizing a talk by Stanley Fischer at this past winter's American Economic Association meetings . Fischer was a high official at the International Monetary Fund.
The article is premium content on The Economist's web page, but Brad DeLong has provided an extract, along with the key graphic, here: "In Memory of Rudi Dorbusch". DeLong also provides a useful link to a copy of Fischer's original talk.
