In this paper, we study how access pricing affects network competition when subscription demand is elastic and each network uses non-linear prices and can apply termination-based price discrimination. In the case of a fixed per minute termination charge, we find that a reduction of the...

This paper extends the theory of network competition between telecommunications operators by allowing receivers to derive a surplus from receiving calls (call externality) and to affect the volume of communications by hanging up (receiver sovereignty). We investigate the extent to which receiver...

We study a retail benchmarking approach to determine access prices for interconnected networks. Instead of considering fixed access charges as in the existing literature, we study access pricing rules that determine the access price that network i pays to network j as a linear function of the...

This paper considers a general and informationally efficient approach to determine the optimal access pricing rule for interconnected networks. It shows that there exists a simple rule that achieves the Ramsey outcome as the unique equilibrium when networks compete in linear prices without...

Many of the attributes that make a good "socially responsible" are credence attributes that cannot be learned by consumers either through search or experience. Consumers aggregate information about them from several channels (media, advertisement, NGOs, etc.). Since these sources may send...

Broadly speaking, pharmaceutical policy in Spain has been unable to control either the price or the volume of drugs prescribed. Limited attempts have been made to bring together the regulation of the pharmaceutical market and policies, in pursuit of the desired goals of efficiency and quality....

We study the standard economic model of unilateral accidents, in its simplest form, assuming that the injurers have limited assets.We identify a second-best optimal rule that selects as due care the minimum of first-best care, and a level of care that takes into account the wealth of the...

This article analyses the impact of the reference price system on the price-setting strategies of the pharmaceutical firms and on the level of generic usage. This model is the first to take explicitly into account the impact of the reference price mechanism on the level of competition between...

This paper analyzes the problem of abnormally low tenders in the procurement process. Limited liability causes firms in a bad financial situation to bid more aggressively than good firms in the procurement auction. Therefore, it is more likely that the winning firm is a firm in financial...

Most cases of cost overruns in public procurement are related to important changes in the initial project design. This paper deals with the problem of design speciffication in public procurement and provides a rationale for design misspeciffication. We propose a model in which the sponsor...
