The Great Gatsby curve is a chart plotting the (positive) relationship between inequality and intergenerational social immobility in several countries around the world. The curve was introduced in a 2012 speech by chairman of the Council of Economic Advisers Alan Krueger, and the President’s Economic Report to Congress, using data from labor economist Miles Corak. The name was coined by former Council of Economic Advisers (CEA) staff economist Judd Cramer, for which he was given a bottle of wine as a reward. The curve plots "intergenerational income elasticity"—i.e. the likelihood that someone will inherit their parents' relative position of income level—and inequality in the United States and twelve other developed countries, though some versions of the curve include developing countries.
