Gary Burtless and Christopher Jencks find that market income inequality in the United States is similar to that in other OECD countries but that taxes and transfers did more to redistribute these market incomes in other OECD countries in the 1990s, with the result that disposable incomes were more unequal in the United States in that decade.

Authors’ calculation from Congressional Budget Office, "Historical Effective Federal Tax Rates, 1979-2003" (December 2005), table 1-C. The CBO calculations use the Census Bureau’s fungible value measure to determine the cash equivalent of in-kind government transfer payments. The CBO adjusted the resulting measure of comprehensive income for differences in the size of households in order to assign households to income quintiles. Quintiles contain equal numbers of people, but because households vary in size, quintiles generally contain unequal numbers of households. 4. Ibid. 5. Arthur B.
