Abstract
The American Economic Association awarded the 2025 John Bates Clark Medal to Stefanie Stantcheva of Harvard University. Her research ranges widely in the field of public economic. It includes theoretical contributions to optimal income taxation, empirical contributions to the study of how income tax rates across countries and states affect the mobility of inventors and the level of innovation, and contributions in the development and execution of on-line surveys to measure respondents' beliefs about economic primitives, such as the distribution of income or the rate of inflation, and the way these beliefs influence policy preferences. She has demonstrated that randomized controlled trials can be embedded within on-line surveys and used to the way informational interventions and other treatments affect economic beliefs and policy preferences.
