Secretariat provides trusted economic expertise across the full spectrum of antitrust matters, from government investigations and merger reviews to monopolization disputes and private class actions involving alleged monopolization and cartel behavior. Our team delivers rigorous analysis, persuasive testimony, and practical insight that help clients navigate complex competition challenges with confidence.
Regulators and courts regularly rely on economic insights to determine the competitive impact of specific transactions and conduct. In this legal environment, Secretariat has earned a position as a preeminent resource for trusted, independent antitrust and competition analysis that is backed by experience with key economic issues, state-of-the-art empirical analysis, and an ability to present complex information in clear, understandable terms.
Antitrust investigations and litigation of proposed mergers and acquisitions (M&A) or allegedly anticompetitive conduct — whether government-initiated or a private action — requires the kind of clear, expert economic analysis Secretariat’s antitrust economists are known for and have provided for decades. Together, our experts have been retained in more than 1,400 antitrust matters across nearly all industries.
Antitrust review of M&A transactions by regulators inherently and routinely involves answering economic questions. How is a market defined? What will be the transaction’s competitive effects? Answering these and related questions requires a thorough grasp of the nature of competition in specific markets and detailed empirical analysis and modeling of market conditions. Obtaining clearance for the transaction depends on clear analysis and persuasive presentation to regulators. Secretariat’s experts provide thorough data analysis, modeling, and objective advice clients need when considering a transaction, as well as the detailed and fact-based documentation and presentations regulators value.
When antitrust disputes emerge, there is no substitute for experts with the ability to present clear and understandable economic analyses to judges, juries, government regulators, and arbitrators. Secretariat’s experts provide straightforward and convincing testimony in disputes involving price fixing, bid rigging, and monopolization claims. Whether the testimony relates to theories and the analysis of competitive harm, class certification, or damage estimation, our experts are adept at merging sound economic evaluations and reasoning with prevailing legal standards, actual case law, and the unique facts of every matter.
In addition to our expert economic work in merger reviews and antitrust litigation, Secretariat provides critical support in regulatory and enforcement investigations, including those involving alleged price-fixing, bid rigging, and cartel conduct. Our professionals assist white-collar attorneys and in-house counsel in both criminal and civil antitrust investigations by preparing detailed reports, tracing communications, and analyzing complex patterns of collusion and pricing behavior. We offer expert testimony and strategic advice grounded in empirical analysis. Our team of forensic accountants, data scientists, technologists, and economists applies a rigorous, coordinated approach to uncovering key facts and examining evidence. This integrated capability ensures a comprehensive response to investigative demands and supports clients navigating high-stakes antitrust inquiries with clarity and confidence.

Antitrust scrutiny of the National Collegiate Athletic Association (NCAA) has a long history, rooted in tensions between the organization’s role as a regulator of college sports and the requirements of U.S. competition law. Until 2014, the NCAA relied on amateurism as its primary defense against antitrust challenges, particularly regarding limits on athlete compensation.
