From 2005 to 2007, she was deputy assistant secretary for microeconomic analysis at the Department of the Treasury. Previously, she was an economics faculty member at the University of California at Berkeley, a national fellow of the National Bureau of Economic Research, a visiting economist at the International Monetary Fund, and a visiting scholar at AEI. Ms. Eissa's research examines how tax and transfer policy affects work and family-formation decisions, and in turn what these behavioral responses imply for how programs should be designed. Her work has been published in major economics journals and widely cited in the media. Ms. Eissa's current research has expanded into education, including evaluating the DC Opportunity Scholarship Program, the first federally funded school-voucher program in the United States, and the impact of school choice on academic performance in public schools.
