After working as a staff economist at the Federal Trade Commission, Dr. Abrantes-Metz continued to serve as a consultant for special projects with the Commission’s Bureau of Economics and she is also a consultant for the World Bank. Dr. Abrantes-Metz is the author of several articles on econometric methods and screens, conspiracies and manipulations, gasoline, pharmaceuticals and health care, telecommunications, monetary policy, event studies, valuation, structured finance, credit default swaps, credit ratings and new statistical tests, representing some of the areas in which she has also worked as an economic consultant. Dr. Abrantes-Metz has published in various peer-reviewed journals and trade publications. She is a co-drafter of the chapter on the role of the economic expert in proving conspiracy cases under federal antitrust laws in a recent volume published by the American Bar Association. In addition she has contributed to other books on international arbitration with a focus on event studies, and is a co-author of the chapter on corporate governance and compliance forthcoming in the next Handbook on Antitrust Economics.

Dr. Abrantes-Metz has developed numerous empirical screens for conspiracies and manipulations, and is a pioneer in the field, contributing to the further development and increased adoption of these methods. She has flagged potential anticompetitive behavior preceding large scale investigations, such on the alleged Libor conspiracy and manipulation, and has also used these methods to defend against allegations of such behavior. Her screens are used by competition authorities, defendants and plaintiffs worldwide. In pharmaceuticals, she has co-developed a model to estimate the likelihood of drugs failing and succeeding each of the clinical stages of the Food and Drug Administration, and their expected durations in each of these phases. This model has become one of the two most used by industry analysts to value pharmaceutical and biotechnology pipelines. Dr. Abrantes-Metz has provided testimony related to alleged bid-rigging, price-fixing, market allocation, and on valuation of oil services and utilities services companies.

Dr. Abrantes-Metz holds a Ph.D. and a Masters in Economics from the University of Chicago. She also holds a Masters in Economics from the Universitat Pompeu Fabra in Barcelona, Spain, and a Licenciatura in Economics from Universidade Católica Portuguesa in Lisbon, Portugal.


  • 184. BP argues that the ID errs in giving Abrantes-Metz significant weight because she had no experience in natural gas markets and had not testified in any case in the United States involving alleged manipulation of natural gas or power markets. However, the ID directly considered BP’s “challenges [to] this witnesses qualifications to testify as an expert in gas trading” and found that she was “more than amply qualified to testify in this proceeding.” Having determined that Abrantes-Metz’s testimony and evidence was admissible under Rule 509, the ALJ then determined that the substance of Abrantes-Metz’s testimony and evidence deserved significant weight in light of the record. BP’s attacks on Abrantes-Metz’s qualifications, which the ID considered sufficient to qualify her testimony and evidence for admission in this proceeding, provide no basis for the Commission to reject the ALJ’s determinations regarding the weight and credibility afforded to Abrantes-Metz and her testimony and evidence. – (Source: Appeal Decision: BP found guilty of natural gas market manipulation).
  • 239. The ID also found that Enforcement Staff expert witness and testimony conclusively showed Comfort’s explanations to be not credible. The ALJ found Abrantes-Metz’s testimony to show conclusively that the confluence of factors in this case indicates that there is no legitimate reason to explain the Texas Team’s trading patterns other than manipulation.” – (Source: Appeal Decision: BP found guilty of natural gas market manipulation).
