In this episode of Trust and Trade, Dr. Elizabeth Wang, Executive VP of economic consulting firm Compass Lexecon, explains how antitrust enforcers use the Gross Upward Pricing Pressure Index (GUPPI) analysis to determine whether to stop a merger. Dr. Wang walks listeners through what the GUPPI test is, what it tells you, when to use it, and its advantages and limitations. Later, host Anant Raut and co-host NERA's Anton Kandalin discuss how the GUPPI test was used to challenge the Penguin Random House and Simon & Schuster mergers.
