The gas deregulation process implies crucial choices concerning access to transportation networks. These choices deal with the nature, the structure and the level of access fees. This paper proposes an evaluation of different systems implemented both in Europe and North America, in relation to...

In this paper, we propose to analyze optimal nonlinear pricing when a firm offers in a bundle a commodity and a contingent service. The paper studies a mechanism design where all private information can be captured in a single scalar variable in a monopoly context. We show that to propose the...

We develop a yield-based capital budgeting method that solves the inconsistencies of the internal rate of return (IRR) and its alternatives with the shareholders' wealth maximization objective. We thus provide an efficient technique for managers who exhibit in practice a large preference for...

We study the case of a competitive firm exposed to both input and output price risk. In an expected utility framework, we elicit the separation theorem, and show the positive impact of derivatives markets on the optimal output. We also show that in the case of several inputs, the risk-averse...

Our work concerns the Internet network. We propose to modify the traditional analysis of the theoretical economic literature which emphasizes on the vertical integration among backbones and ISPs, and his difficulties because IBPs have a strongmarket power. We propose to build a sequential game...

The increase of bundle supply has become widespread in several sectors (for instance in telecommunications and energy fields). This paper review relates strategic aspects of bundling. The main purpose of this paper is to analyze profitability of bundling strategies according to the degree of...

This paper evaluates convergence of energy intensities for a group of 97 countries in the period 1971-2003. Convergence is tested using a recent method proposed by Pesaran (2007) [M.H. Pesaran. A pair- wise approach to testing for output and growth convergence. Journal of Econometrics 138,...

This paper studies competition between Managed Care Organizations (MCOs) and “Conventional Insurers”. Most of the time, MCOs sign exclusive contracts with providers and these vertical restrictions associated to differentiation in the providers'market imply a risk segmentation. Taking into...

The aim of this paper is to assess theoretical consequences of restructuring electricity markets on the environment. We examine changes in potential behaviours in consumption-side as well as in supply-side. We show that restructuring and following access to competition is not neutral from an...

The aim of this paper is to examine portfolio management of emission allowances in the US Sulfur Dioxide Emissions Allowance Trading Program, to determine whether utilities have a real motive to bank when risk increases. We test a theoretical model linking the motivation of the firm to...
