Expert Analysis Group
The Expert Analysis Group (EAG) of the Antitrust Division is one of the world’s leading venues for developing and applying economics to real world questions of competition. We are a group of approximately 50 Ph.D. economists, complemented by statisticians, data scientists, and financial analysts. Economists here analyze the competitive effects of horizontal and vertical mergers and of potentially anticompetitive business practices. We routinely incorporate internal corporate data, business documents, and information from interviews of executives to understand and model competition from a perspective that is unavailable in typical academic settings. As a result, EAG economists can develop a uniquely relevant understanding of firm conduct in a wide variety of industries. Our analysis plays a central role in enforcement efforts to protect competition and benefit consumers through low prices, high quality, and innovation.
EAG is led by the Chief Economist, the Principal Economist, and career managers. The positions of Chief and Principal Economist are typically filled by prominent economists on leave from an academic post.
