This episode kicks off Trust and Trade's "Mergernomics" series, demystifying the economic analysis that antitrust enforcers use to predict whether a merger will harm competition and should be blocked. Host Anant Raut and co-host January Kim welcome Aditi Mehta, Economics Director for the DOJ Antitrust Division, to give an overview of the role of economists in merger review, common frameworks for understanding competitive harm, quirks of special markets like platforms and labor, and some of the most used tests to evaluate merger effects.
