Rediscovering the 1%: Economic Expertise and Inequality Knowledge
In the 2000s, academics and policymakers began to discuss the growth of topincomes in the United States, especially “the 1%” Newly analyzed tax datarevealed that top incomes had begun a dramatic upward climb in the early1980s. This article investigates why it took two decades for this increaseto become politically and academically salient. I show how expertsassembled two “regimes of perceptibility” for producing knowledge aboutincome inequality, and that neither was capable of tracking top incomes.Macroeconomists focused on labor’s share of national income, but ignoredthe distribution of income between individuals. Labor economists drew onnewly avail- able survey data to explain wage disparities. By relying onsurveys, these scholars unintentionally eliminated top incomes from view:surveys top-coded high incomes and thus were incapable of detecting therise of the 1%. Studies of top incomes that relied on income tax data fellby the wayside, creating the conditions under which experts, policymakers,and the public alike could be surprised by the rise of the 1%. Thishistorical study offers insights into the political power of economicexpertise by clarifying the complex linkages between observations, stylizedfacts, causal theories, and policy attention.
