We consider a dynamic model of price regulation with asymmetric information where strategic delegation is available to the regulator. Firms can sink non-contractible, cost-reducing investment but regulators cannot commit to future price levels. We fully characterise the perfect Bayesian...

We consider a model in which Cournot-Nash oligopolistic service providers are able to trade radio spectrum licences, subject to interference constraints. The terms of trade are endogenised through Nash bargaining. When the providers are in the same (geographical) market, the incentive to trade...

This paper examines a general problem exemplified by post-auction (third generation---`3G') mobile telecommunications markets. When entering these (or any other) markets, firms must often decide on the degree of coverage (`roll-out') they wish to achieve. Prior investment must be sunk in order...

Administered Incentive Pricing (AIP) of radio spectrum as advocated by Smith/NERA (1996) and recently assessed by Indepen (2003) envisages an incremental path towards e±cient pricing, with revealed and stated prefer- ence methods being used to reveal opportunity costs. We build on the latter to...

We investigate the potential economic effects of spectrum trading amongst firms who require spectrum licences as part of their activities. Trading takes place within the technical interference constraints enforced by a regulator. The model accommodates a variety of markets and firms, as well as...

Treating spectrum of different bandwidths as essentially distinct inputs needed for possibly different types of services has formed the core of spectrum analysis in academic research so far. New technological advances, such as cognitive radio, now allow us to move away from this inflexibility...

This paper combines models and ideas from radio-engineering literature and economics to address the need for regulation of spectrum allocation in a commons scenario. It discusses under what conditions a laissez-faire policy towards spectrum usage would engender the inefficiencies of a spectrum...

This paper examines optimal price (i.e. ‘sliding scale’) regulation of a monopoly when productivity and managerial effort are not observed. We show how to operationalise this model of incentive regulation and use actual data from electricity distribution in England and Wales to make welfare...

This paper examines optimal price (i.e. 'sliding scale') regulation of a monopoly when productivity and managerial effort are not observed. We show generally how to operationalize this model of incentive regulation and use actual data from electricity distribution in England and Wales to...

We consider two aspects of the commitment problem in price regulation with lobbying the ratchet effect and the hold-up problem. We set out a dynamic model of price regulation with asymmetric information where the regulated firm can ‘buy influence’ in a lobbying equilibrium. Firms can sink...
