"Investment and Welfare Implications of the Ownership Structure of Overlapping Networks", 2008, Information Economics and Policy, Vol 20/1, pp. 38-53 with Pedro Pereira (Autoridade da Concorrência).

Abstract : We analyze the impact of the ownership structure of cable television firms on the incentives to upgrade the cable networks to offer telecommunication services. First, we show that dual ownership of a local telephone network and a cable network, compared with separate ownership, may increase or decrease incentives to invest in upgrading the cable television network. Coordination economies benefit dual ownership, and business-stealing benefits separate ownership. Second, we perform a welfare analysis of the investment decision and third, a welfare analysis of the ownership structure.
