Autore: Lanzi, Diego Titolo: Prezzo di accesso e competizione multimercato nelle Network Industries Periodico: L'industria Anno: 2002 - Volume: 23 - Fascicolo: 2 - Pagina iniziale: 215 - Pagina finale: 229
In this essay a model of one-shot multimarket competition between conglomerate firms, competing into a network industry, is presented. Consequently a multimarket oligopoly, defined as a set of oligopolistic markets, is quickly characterised. One of these is a network market where a vertically integrated firm sells unit of access to a competitor. The existence of multimarket competition justifies relevant changes in the socially optimal access charge set by a fully informed regulator. Hence, a possible linkage between access pricing and a new paradigm of competition phases out.
