This paper evaluates the impact of the tightening in price cap by OFWAT and of other operational factors on the efficiency of water and sewerage companies in England and Wales using a mixture of data envelopment analysis and stochastic frontier analysis. Previous empirical results suggest that...

We address Allan Shampine's critiques of our study on the costs and benefits of payment instruments, and review the current state of the literature. We argue that a consensus seems to be emerging in which: (a) different payment instruments appear to be socially efficient at different transaction...

This paper aims to empirically establish the determinants of merchant participation in credit card payment schemes. It is found that a merchant's personal background, type of business and total value of sales are significant in determining a merchant's acceptance of cards in payment...

This paper develops a model incorporating costly disinvestment and estimates the associated commitment premium required to invest in telecommunications. Results indicate that the irreversibility premium raises the opportunity cost of capital by 70 percent. This implies an average annual hurdle...

The goal of SEPA (Single Euro Payments Area) is to facilitate the emergence of a competitive, intra-European market by making cross-border payments as easy as domestic transactions. With cross-border inter-operability for electronic payments, card transactions will increasingly replace cash and...

This paper argues that a cable operator with sufficient market power in the downstream multi-channel video programming distribution (MVPD) market can deny access to unaffiliated programmers, resulting in an upstream programming rival's exit or impaired dynamic efficiency. Further, market...

Most digital goods have a modular design; that is, they consist of complementary and distinct building blocks, called modules. Modular product design, in contrast to integrated (or integral) design, enables alteration of a specific module that is usually assigned for a specific function without...

This paper analyzes telecommunications demand by firms, focusing on communication flows among production units. We consider first the case of two business units, that can play simultaneously or in a leader/follower situation regarding their communication decisions. In this context, we define the...

Incompatibility across rival systems can influence incentives to invest in product changes beneficial to the consumer. We investigate this phenomenon in the case of bank ATM networks, where the number of ATM locations is a measure of product quality and surcharge fees serve as an index of...

In this paper, we survey the literature on optimal pricing of a monopolist operating on a network industry. We also describe explicitly the optimal path of prices for a monopolist facing an expanding demand due to the presence of network effects. The optimal path of prices appears as a function...
