ABSTRACT: In this paper, a new empirical screen for detecting cartels is developed. It can also be used to date the beginning of known conspiracies, which is often difficult in practice. Structural breaks that are induced by cartels in the data generating process (DGP) of industry prices are detected by testing reduced form price equations for structural instability. The new screen is applied to three European markets for pasta products, and it successfully reports the cartels that were present in the Italian and Spanish markets, but finds no suspicious patterns in the French market, which was not cartelised.
