Our issue this month, organized by Rosa Abrantes-Metz, brings together antitrust theory and practice. We look at the econometric approach of screening as a way to identify possible cartels and other collusive activities, analyzing how to apply screens both from the regulators’ and the potential defendants’ perspectives. The analysis is illustrated with real-life applications to the LIBOR market, bid-rigging in Mexico, and price-fixing in Brazil. We conclude with a special interest article giving an indepth comparison of the U.S. and European approaches to quantifying antitrust damages.
