What is a good balance between competition and coordination in network industries? Network unbundling aims to promote … competition, but this has to be balanced against the downside of unbundling: firm-internal coordination falls away and must be … coordination. This paper examines three persistent sources of flawed coordination: 1) a regulation versus unbundling dilemma, 2 …

Network shares and retail prices are not symmetric in the telecommunications market with multiple bottlenecks which … give rise to new questions of access fee regulation. In this paper we consider a model with two types of asymmetry arising … from different entry timing, i.e. a larger reputation for the incumbent and lower cost of servicing for the entrant as a …

We study the regulation of a monopolistic firm that provides a non-marketed output based on multiple substitutable … costs. For this novel setting, we investigate the theoretically optimal Bayesian regulation mechanism. We find that the … non-Bayesian regulation can indeed get close to the second best of the Bayesian menu of contracts regulation. …
