Melissa Dell and Ashesh Rambachan Present 2026 Methods Lectures

Research Associate Melissa Dell of Harvard University and Ashesh Rambachan of MIT delivered the 2026 Methods Lectures on "Estimation and Inference with AI-Generated Data." They described both the rapidly expanding ways in which large language models and other AI tools are being used for economic measurement, as well as the new econometric issues that are presented by the analysis of these data. Their lectures provided an overview of the theory underlying some of the new econometric tools and illustrated their application in several different settings.
