Against a background of increased decentralisation in the structure of wage decision making, we analyse the effects of unions on the dispersion and persistence of pay settlements over the medium term using a longitudinal data set covering British private sector establishments over the period...

The number of strikes reported in British industry has been on a downward trend over the past two decades, falling in 1998 to their lowest level since records began. This may indicate that relations within British industry have improved, however, the same period has also witnessed a sharp...

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...

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...

For the first time, we test for effects of liability on hospital care using measures of current perceptions of litigation risk at hospital level; in particular, the risk-sharing arrangements agreed between hospitals and their insurers. GMM and ML estimators are used to allow for possible...

Principals who exercise favouritism towards certain agents may harm those who are not so favoured. Other papers have produced evidence consistent with the presence of such favouritism but have been unable to consider methods for controlling it. We address this issue in the context of a natural...

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...

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...
