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

Recently, investments in new generation networks in Germany have been curtailed, since potential investors required this new network be unregulated. To develop a regulator's strategy that allows investments to occur but prevents monopolistic prices, we model an investor's decision problem under...

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...

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 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...

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...

We develop a dynamic model of collusion in airport-pair routes for selected US airlines and specify the first order conditions using a state-space representation that is estimated by Kalman-filtering techniques using the Databank 1A (DB1A) Department of Transportation (DOT) data during the...

This article revisits the research in "The Move Toward a Cashless Society: A Closer Look at Payment Instrument Economics" in order to clarify assumptions underlying the theoretical model and how they impact the included cost and benefit categories; evaluate the estimates' plausibility by...

This paper addresses the investment impact of network sharing mandated by the 1996 Telecommunications Act. Such investments involve sunk costs and so are irreversible. Regulators allow entrants to utilize such facilities at prices reflecting the cost of building a new, efficient, large-scale...
