Dr. Rosa Abrantes-Metz is an expert in economic matters related to collusion, market manipulation and fraud, and multisided platforms, as well as regulation, financial and commodities markets, and valuation.

Having worked in economics for over two decades, Dr. Abrantes-Metz is skilled in providing antitrust and market analyses. She pioneered the development and application of empirical screens to detect potential collusion, manipulation, and fraud, including in the uncovering of LIBOR rigging and other financial benchmarks. She has advised multiple agencies in five continents on the adoption of these screens, which are now commonly used worldwide. Dr. Abrantes-Metz is also experienced in multisided platforms matters, event studies, and valuation.

Over the course of her career, Dr. Abrantes-Metz has provided testimony on behalf of both governmental agencies (including the Federal Energy Regulatory Commission and the Department of Justice), and private institutions in many areas, both plaintiffs and defendants. Her testimony has focused on price artificiality and damages, causation, class certification, bid-rigging, price-fixing and market allocation, market manipulation, fraud, market definition, multisided platforms, mergers and acquisitions, monopolization, benchmarks reform, and valuation. Her work spans a wide range of industries, including pharmaceuticals, oil and natural gas, transportation and catering, precious metals and other commodities, payments systems, foreclosures and evictions, and various financial instruments spanning multiple markets.

Dr. Abrantes-Metz has published extensively in peer-reviewed journals; trade publications; handbooks; and mainstream media publications such as The Wall Street Journal, The Financial Times, and Bloomberg. She is also often interviewed by these outlets and others, including The Economist, Reuters, CNBC, CNNMoney, Forbes, Fox Business, BusinessWeek, Washington Post, Investor’s Business Daily, BBC Radio, Sky News, and BNN Bloomberg.

She is a former adjunct associate professor at the NYU Stern School of Business, and a former Lecturer at The University of Chicago and Portuguese Catholic University. Her academic background and experience in monetary and financial economics, industrial organization, and econometrics strengthens her ability to apply economic analyses to consulting work. Prior to joining Brattle, Dr. Abrantes-Metz was a Managing Director at an international economics consulting firm, and a staff economist at the Federal Trade Commission. She is a senior competition policy advisor for the World Bank.

Dr. Abrantes-Metz has been included in Who’s Who Legal’s list of Competition Economists since 2009.
