Broadband investment and welfare under functional and ownership separation
نویسندگان
چکیده
We study how the vertical industry structure affects investment in network quality and social welfare, with a focus on the prospective deployment of high-speed broadband access networks (the so-called NGA). We model pros and cons of vertical separation, namely, procompetitive effects and loss of some efficiencies of vertical integration, and distinguish functional separation from ownership separation. Our findings challenge the presumption that (compared with vertical integration) vertical separation reduces investment incentives and involves a trade-off between promoting consumer surplus and ensuring investment. While investment is higher under ownership rather than functional separation, the latter may yield the highest social welfare among vertical industry structures. Furthermore, the incumbent may voluntarily opt for functional separation, but in some of these cases, prohibiting separation improves welfare. 2014 Elsevier B.V. All rights reserved.

Network investment under legal and ownership unbundling1
We consider an industry where an upstream rm determines the size of a network used by two downstream rms. We contrast ownership unbundling and legal unbundling, where the upstream rm maximizes its total pro t, including the pro t of its downstream subsidiary(ies), but does not discriminate between them. Furthermore, each downstream subsidiary maximizes its own pro t. We show that ownership s...

We analyze the impact of the ownership structure of cable television rms on the incentives to upgrade the cable networks to o¤er 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.

متن کاملCapital Investment and Determinants of Financial Constraints in Estonia
Unlike previous empirical work concerning investment behavior and the determinants of liquidity constraints, we use a switching regression framework when sample separation is unknown and endogenous and firms are assumed to operate either in the financially constrained or in the financially unconstrained regime. By using new panel data for Estonian companies during 1993 through 2002 we find that...
