The Center for Forensic Economic Studies provides economic and statistical analysis and testimony in commercial, injury, wrongful-death and employment litigation. Economists at the Center analyze such issues as economic loss due to injury and breach of contract and statistical liability in disparate-impact claims in employment litigation. Senior staff includes economists, a forensic accountant, a human-resources specialist and an information-technology specialist. We assist in discovery, uncover key data, critique opposing claims and provide clear, credible reports and testimony.


The Center for Forensic Economic Studies is a leading provider of economic and statistical analysis relating to litigation.

Our areas of concentration include:

- Personal Injury / Wrongful Death Damages
In analyzing damages in personal-injury and wrongful-death matters, the Center works closely with clients, gathering necessary data, identifying relevant issues and calculating the extent of economic loss. The Center's forensic economists analyze such economic-damage elements as lost earning capacity, fringe benefits, medical costs, life-care plans, productivity, lost household services and personal maintenance.

- Labor and Employment: Litigation Damages
Damages in employment cases are affected by a number of issues, including mitigation efforts on the part of the plaintiff, the state of relevant labor markets, extent of back- and front-pay and valuation of fringe benefits, including employee stock options. Center economists have developed a particular expertise in the analysis of these variables and have written and lectured widely on employment-damages topics.

- Labor and Employment: Disparate Impact Analysis
The Center has extensive experience analyzing liability issues arising in claims of disparate impact in labor and employment matters. The Center has been called on to provide analysis in terminations-for-cause actions and hiring, promotion and compensation cases. Center statisticians have testified in hundreds of cases for both plaintiffs and defendants and have also been retained as court-appointed experts. In addition to direct litigation support, Center economists offer employment-compliance audits that help employers identify potential problem areas prior to reductions-in-force (RIFs).

- Commercial Damages / Lost Profits
The Center has been called on to provide analysis in many commercial areas, including antitrust, business interruption, patent infringement, assessment of financial incentives for arson, excess compensation, business valuation, breach of contract and tortuous interference. Center forensic economists have analyzed lost-profit and accounting-fraud claims arising in a wide variety of industries, and excel at uncovering and interpreting data, financial documents and facts germane to such claims.

- Business Valuation / Appraisals
The Center consults on a variety of appraisal matters, including sales and financing arrangements, shareholder disputes, distributor consolidation and business valuations. Center economists have significant experience and expertise in the technical and legal issues that may arise when assigning a value to a business.
