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...

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...

We propose a theory of supervision with endogenous transaction costs. A principal delegates part of his authority to a supervisor who can acquire soft information about an agent's productivity. If the supervisor were risk-neutral, the principal would simply make the better informed supervisor...

Generic competition in the pharmaceutical market is an effective cost-containment mechanism that improves static efficiency and stimulates pharmaceutical innovation. There is no prior study that has empirically analysed the relative delays in adoption of generic competition. This paper aims to...

Entry regulations against big-box retailers have been introduced in many countries to protect smaller independent stores. Using a new dataset from the UK, I show that in fact these entry regulations have been associated with greater employment declines in independent stores they were meant to...

Few studies conceive of land as a productive factor but British land use policies may lower total factor productivity (TFP) in the retailing industry by (i) restricting the total availability of land for retail, thereby increasing space costs (ii) directly limiting store size and (iii)...

In the European Union, medicines are regulated products subject to both single market (e.g., regional exhaustion of property rights) and country specific health care regulations (e.g., medicines pricing). This gives rise to parallel trade (PT), a phenomenon that takes place when a patented...

The financial crisis has generated a deep revision of the regulation of securities and derivatives markets. In this paper, we critically examine the extent to which current reforms, such as the European Market Infrastructure Regulation and the proposed new Markets in Financial Instruments...

This paper examines the impact of regulatory intervention to cut termination rates of calls from fixed lines to mobile phones. Under quite general conditions of competition, theory suggests that lower termination charges will result in higher prices for mobile subscribers, a phenomenon known as...

During the past few decades a number of European countries lifted the regulations that restricted the opening hours of shops on Sunday. In this paper we examine the impact of Sunday trade deregulation on employment, expenditure, prices and market structure using a difference-in-difference...
