This article presents a dynamic Generalized Nash-Cournot model to describe the evolution of the natural gas markets. The aim of this work is to provide a theoretical framework that would allow us to analyze future infrastructure and policy developments, while trying to answer some of the main...

This paper introduces a general static Cournot-game model to study the Natural Gas market, taking into account disruption risks from suppliers. In order to most realistically describe the economical situation, our representation divides the market into two stages: the upstream market that links...

Most of the recent numerical market partial equilibrium models of natural gas markets use imperfect competition assumptions. These models are typically embedded with a simple representation of the demand side, usually a single-variable, linear, inverse demand function, that does not capture any...

This article presents a dynamic Generalized Nash–Cournot model to describe the evolution of the natural gas markets. The major players along the gas chain are depicted including: producers, consumers, storage and pipeline operators, as well as intermediate local traders. Our economic structure...

In this paper, we analyze the impact of uncertain disruptions in gas supply upon gas retailer contracting behavior and consequent price and welfare implications in a gas market characterized by long-term gas contracts using a static Cournot model. In order to most realistically describe the...

We consider a simple general equilibrium model with imperfect competition. Firms are price taker in the input market and compete à la Cournot in some or all of the product markets (their technology displays constant returns to scale). We show that an increase in the number of firms does not...

We consider a double moral hazard model with three agents: the entrepreneur, the LBO fund and the bank. The entrepreneur and the LBO fund have to exert efforts in order to improve the productivity of their project; efforts are not observable. We show that the bank's payments decrease with the...

This paper extends the analysis of insurance contracts design to the case of "low probability events", when there is a probability mass on the event "no accident-zero loss". The optimality of the deductible clause is discussed both at the theoretical and empirical levels.

Parties engaged in a litigation generally enter the discovery process with different informations regarding their case and/or an unequal endowment in terms of skill and ability to produce evidence and predict the outcome of a trial. Hence, they have to bear different legal costs to assess the...

This study tests an international extension of the Asset Pricing Model (CAPM) based on the coexistence of two risk causes. The first cause is linked to the market portfolio and the second one is required by expectations about the variation of exchange rates. Through an application to various...
