Netzzugang, Wettbewerb und Investitionen

We analyze the role of different contract types and access regulation on innovation and competition in telecommunications. Within a standard duopoly model we show that ex-post access contracts less often lead to the duplication of investment but to a wider roll-out compared to a market in which such contracts cannot be offered. In comparison to such ex-post contracts lead ex-ante contracts to even wider roll-out, but an even less frequent duplication of investments. In particular ex-ante contracts, but also ex-post contracts can be used as an instrument to reduce competitive pressure in the industry.
