This project addresses the slowdown in US economic growth since 2000 by focusing on how microeconomic policy changes can spur growth. Recognizing that many growth-related policy levers are microeconomic in nature, the project aims to bridge a gap in existing research that often prioritizes economic efficiency or distributional consequences over growth impacts. It will support nine studies by subject-matter experts, synthesizing existing research and conducting new analysis to assess the economic growth consequences of microeconomic policy changes, such as R&D investment incentives and expedited permitting for infrastructure. The project will convene working meetings and a capstone conference, involving macroeconomists and economists from non-partisan federal agencies, to ensure robust analysis and relevance to policy debates. The findings will be compiled into a conference proceedings volume for publication, injecting microeconomic evidence into policy discussions on promoting US economic growth.
