Econometrics Expert Witnesses
Econometrics disputes in complex commercial litigation typically arise when a case requires rigorous statistical modeling to establish or rebut claims about market behavior, damages, or causation, questions common to antitrust, securities, and class action litigation. These disputes surface in antitrust matters where economists model whether alleged anticompetitive conduct affected prices or output, in securities litigation requiring event studies to isolate the market impact of an alleged misrepresentation, and in class certification disputes where the propriety of common statistical methods for proving classwide impact is contested. Because econometric models depend on data selection, specification choices, and statistical assumptions that can be built in different defensible ways, reasonable economists applying accepted techniques to the same data can reach different conclusions. The central issue is typically whether the econometric model and underlying data support the causal or quantitative claim it is being used to prove.
An econometrics expert helps attorneys evaluate that question by constructing or critiquing statistical models that isolate the effect of the conduct or event at issue from other factors that might explain the observed outcome. That might mean building a regression model to estimate but-for prices in an antitrust case, conducting an event study to measure a stock's abnormal returns following an alleged disclosure in a securities matter, or evaluating whether a proposed damages methodology can reliably measure classwide impact for certification purposes. These findings support positions on liability, causation, damages, and class certification, and often anticipate the modeling choices an opposing econometrics expert is likely to challenge.
Econometrics cases benefit from experts whose specific applied background, whether antitrust economics, financial econometrics, or labor and program evaluation, matches the precise statistical question at issue rather than econometrics in general terms. Round Table Group's econometrics network includes scholars and industry professionals in finance, economic theory, forecasting, and risk management, many of whom are prolific authors and frequent conference speakers with direct experience applying econometric methods to litigation-specific questions. With more than 75,000 expert searches completed for litigators, we help attorneys match a case's specific econometric issue to an expert whose modeling will withstand scrutiny under cross-examination.
