About
Dan Greenfield joined NERA in 2025 with more than 12 years of experience at the Federal Trade Commission (FTC). He specializes in evaluating the competitive effects of mergers and unilateral business conduct. At the FTC, he led teams of economists on matters in industries including oil and gas, refining, pipelines, cement, coal, chemicals, financial services, medical devices, software, retail, consumer goods, technology hardware, social networking, and video games. Dr. Greenfield prepared to testify as an economic expert in numerous FTC enforcement matters.
Dr. Greenfield authored training materials at the FTC and regularly consulted with other economists on the technical and practical aspects of simulating mergers and the application of econometrics to evaluate industry data. He also published a peer-reviewed article on using upward pricing pressure analysis to predict merger price effects when the merging firms are capacity constrained.
Dr. Greenfield helped draft sections of the 2023 Merger Guidelines. He also co-led the Bureau of Economics’ mentoring program for new economists. He received multiple awards while at the FTC, including the 2021 Paul Rand Dixon Award, an individual award given to an economist for outstanding casework with attention to detail and analytic rigor.
Prior to joining the FTC and NERA, Dr. Greenfield was a lecturer at Northeastern University. He has published research on competition, mergers, and industry regulation in peer-reviewed journals and the FTC working paper series. He has presented research at major academic and policy conferences. His published research includes theoretical modeling and empirical analysis of data from the gasoline, electricity, and airline industries.
