My research examines the role of numbers in political and economic life. I have studied debates surrounding affirmative action and the quantification of merit in undergraduate admissions, political contestation around gender-based pricing of insurance and credit, the history of the measurement of top incomes, and the interaction of financial innovation and financial regulation. I am currently working on a book manuscript on the production and circulation of quantitative descriptions of inequality, tentativey titled Unequal Knowledge: The Stylized Facts of Inequality.
