We re-consider the impact that regulation of call termination on mobile phones has had on mobile customers’ bills. Using a large panel covering 27 countries, we find that the “waterbed” phenomenon, initially observed until early 2006, becomes insignificant on average over the 10-year...

We apply duality methods of linear and convex programming to the problems of operation and rental valuation of facilities for conversion and storage of cyclically priced goods, e.g. , energy. Both problems are approached by shadow-pricing the stock (which is a purely intermediate commodity); and...

Duality methods of linear and convex programming are applied to impute definite marginal values to the fixed inputs of a hydroelectric plant from the operating profit. Our earlier analysis of pumped storage (of energy and other cyclically priced goods) is thus extended to valuation of an...

This paper analyzes the dynamic incentives for technology adoption under a transferable permits system, which allows for strategic trading on the permit market. Initially, firms can invest both in low-emitting production technologies and trade permits. In the model, technology adoption and...

We introduce the papers in this volume and put them into the context of the literature on land use regulation. We then synthesise and draw some conclusions from existing research on land use regulation and interpret the evidence currently available. In the light of this review we then identify...

We study the repeal of a regulation that imposed maximum wholesale and retail markups for all but five fresh fruits and vegetables. We compare the prices of products affected by regulation before and after the policy change and use the unregulated products as a control group. We find that...

In this paper we seek to explain the emergence of different voice regimes, and to do so by using approaches from institutional economics. In particular we analyse the emergence of different voice regimes as a contracting problem; a ¿make¿ or ¿buy¿ decision on the part of the employer. A...

This paper investigates whether the industrial relations climate in Indian States has affected the pattern of manufacturing growth in the period 1958-92. We show that pro-worker amendments to the Industrial Disputes Act are associated with lowered investment, employment, productivity and output...

Using convex calculus, we extend the Wong-Viner Theorem to nondifferentiable costs by equating the capital inputs' rental prices to their profit-imputed marginal values. Thus extended, the short-run approach to LRMC pricing is applied to peak-load pricing with storage.

With L∞ as the commodity space, the equilibrium price density is shown to be a continuous function of the commodity characteristics. The result is based on symmetry ideas from the Hardy-Littlewood-Pólya theory of rearrangements; and it includes, but is not limited to, the case of symmetric...
