Dr. Rosa M. Abrantes-Metz is a managing director at BRG based in New York and Miami. She has over two decades of experience specializing in antitrust, securities, and financial regulation, including work in consulting and banking, as well as in government.
Her main areas of specialization are econometrics and statistics, industrial organization, and monetary and financial economics. Dr. Abrantes-Metz has a particular expertise involving the intersection between alleged market manipulations and competition issues, including alleged coordinated conduct such as collusion and exchanges of information, as well as the economics of multisided platforms. She pioneered the development and application of empirical screens to detect potential collusion, manipulation, and fraud.

She has advised multiple agencies across five continents on their adoption of these screens, which are now commonly used worldwide.
Additionally, Dr. Abrantes-Metz is experienced in general market rigging, event studies, and valuation. She has testified on these topics on behalf of both plaintiffs and defendants, from governmental agencies (including the Federal Energy Regulatory Commission, Department of Justice, and Federal Trade Commission) to private institutions and companies. Her testimony has included price artificiality and damages, causation, class certification, liability, settlement allocations, bid-rigging, price-fixing and market allocation, market manipulation, fraud, valuation, market definition, mergers and acquisitions, monopolization, and benchmarks reform.
Dr. Abrantes-Metz’s work spans a wide range of industries, including pharmaceuticals; airlines; foreclosures and evictions; technology; payments systems and electronic transactions; trading and pricing algorithms; high-frequency trading and spoofing; precious metals and other commodities such as oil, gasoline, and natural gas; complex derivative products; and financial instruments across multiple markets.
A well-published author, Dr. Abrantes-Metz has written extensively for academic journals, industry publications, and mainstream media publications such as The Wall Street Journal, Financial Times, and Bloomberg. She is regularly interviewed by these outlets and others, including The Economist, Investor’s Business Daily, Reuters, Sky News, and BNN Bloomberg.

She has also been awarded a distinction of excellence for economic analyses in a matter by the American Antitrust Institute, and a case she testified in as an expert witness was nominated by Global Competition Review as Matter of the Year.
