The paper assesses the welfare effects of different ways of allocating input price risk between a regulated utility, consumers and speculators in a futures market. A risk-averse utility setting a fixed retail price requires a price that exceeds expected marginal cost, unless an efficient futures market is available. The firm bears no risk when input price risk is transferred to consumers, but c...

In this paper, the possibility of applying simplified schemes, such as cordon pricing, as a second-best solution of the toll network design problem is investigated in the context of a multiclass equilibrium on multimodal networks with elastic demand. To this end a suitable equilibrium model is presented together with an efficient algorithm capable of solving it for large scale networks in quite...

The applying of simplified schemes, such as cordon pricing, as second-best solution to the toll network design problem is investigated here in the context of multiclass traffic assignment on multimodal networks. To this end a suitable equilibrium model has been developed, together with an efficient algorithm capable of simulating large scale networks in quite reasonable computer time. This mode...

We study optimal tolls for network congestion games where players aim to route certain amount of traffic between various source destination pairs. We consider weighted atomic users, unsplittable traffic and arbitrary nondecreasing latency functions. Users are selfish and want to follow routes that minimize their respective latencies. We focus on pure Nash equilibria. A Nash equilibrium profile ...

We show that in a homogeneous-good duopoly market with quality uncertainty and constant unit costs, the Bertrand paradox (i.e., marginal cost pricing) can be avoided.

Network effects can reduce consumption levels across customers when a monopolist chooses optimal nonlinear pricing. The direction and extent of these distortions depend on the relative rates of variation in marginal intrinsic value and marginal network value with customer type. D 2004 Elsevier B.V.

We develop and analyze a model of pricing for digital products with discontinuous supply functions. This characterizes a number of information technology-based products and services for which variable increases in demand are fulfilled by the addition of "blocks" of computing or network infrastructure. Examples include internet service, telephony, online trading, on-demand software, digital musi...

Reactive power as a utility of ancillary service in restructured environment is supplied by Independent System Operator (ISO). Due to the particular importance of optimal pricing strategy in the power market, the study aims to investigate this problem more closely. To this end, first the problems of restructuring, reactive power generation and its associated costs thereof were reviewed and diff...

The article by Thieblemont and colleagues very nicely summarizes the key pathogenetic and diagnostic features and present treatment of splenic marginal zone lymphoma (SMZL). This histologic subtype of non-Hodgkin lymphoma has evolved from being an unrecognized entity in earlier classification systems (such as the Working Formulation[1]), to a provisional entity in the Revised European/American ...
