'Gersen and Steckel have assembled contributions from leaders in consumer behavior, survey design, and litigation to provide a comprehensive review of market research fundamentals and their application in the context of litigation and government investigations. Their book explores relevant case law; provides clear examples of how to apply market research tools; and explains how empirical research, survey design, and qualitative analyses can serve as crucial evidence in examining liability, damages, and questions of common impact. It is certain to become an indispensable tool for practitioners and students of law, behavioral economics, and survey design.' Martha S. Samuelson, CEO and Chairman, Analysis Group Inc.
