Anticompetitive versus competitive explanations of unilateral practices: The identification problem
No full textI consider the application of Article 82 using an economic approach. I argue that proving a given practice anticompetitive or efficient can be usefully framed as an identification problem. I need to spell out in detail not only the anticompetitive story, related to the type of alleged anticompetitive strategy, but also the alternative competitive explanation, extracting the empirical predictions of the two. Comparing the latter, I can identify the factual elements that, occurring under both circumstances, are admissible under both of them, and those that instead, being specific to one of the stories, allow for discriminating between them. I apply this approach to a recent Italian case [Mercato del Calcestruzzo Cellulare Autoclavato, No. A372 (Autoritá Garante della Concorrenza a del Mercato, 24 October 2007)] of selective price cuts, an example of predation where the dominant firm tries to eliminate a competitor by selectively offering discounts to the clients of the target. On the basis of a rich empirical analysis, the Authority condemned RDB, a medium-sized firm active in the market for construction materials. I show that, once the two stories are properly described, the evidence provided in the decision of the Antitrust Authority is consistent with a competitive strategy of decentralized price negotiation, whereas it is in sharp contrast with the empirical predictions derived from a predatory model of selective price cuts. © The Author (2009).

Dma: Digital Markets Act or Digital Markets Armistice?
No full textL’articolo discute numerose problematiche legate al Digital Markets Act, il documento della Commissione europea che introduce un nuovo approccio delle politiche pubbliche nei mercati digitali. Vengono affrontati tre temi tra loro legati. In primo luogo viene analizzata la relazione tra il Dma, i suoi strumenti e modalità di intervento e l’applicazione delle politiche della concorrenza. Si passa quindi a considerare le fonti della concentrazione e del potere di mercato nei mercati digitali e il possibile impatto del Dma nel promuovere la concorrenza all’interno e per il mercato. Concludiamo infine la nostra analisi guardando ai nuovi fenomeni che emergono nel nuovo Web, guidati dalle potenzialità offerte dal 5G e dalla diffusione dell’Internet delle Cose, discutendo se e in quale misura il Dma sarà in grado di adattarsi e incidere su questa evoluzion

Acquisitions, innovation and the entrenchment of monopoly
Full text linkWe analyze a dynamic model of repeated innovation where inventors may either be acquired by an incumbent or else resist takeover and challenge for leadership. In the short run, acquisitions always spur innovation because of the invention-for-buyout effect. In the longer run, however, they may stifle it because of a countervailing effect, the entrenchment of monopoly. The latter occurs when the incumbent's dominance depends on past levels of activity and is therefore reinforced by recurrent acquisitions. We show that if the entrenchment effect is sufficiently strong, forward-looking policymakers should prohibit acquisitions in anticipation of the long-run negative impact on innovation. This argument sets out a new theory of harm that can be used to block acquisitions that could otherwise go unchallenged
