We propose a model of seasonal gas markets which is flexible enough to include supply and demand shocks while also considering natural gas as an exhaustible resource. Using US data, we estimate the model’s structural parameters and test economically founded restrictions. We analyze,...

This article treats energy taxation principles in the light of the need to optimise supply by non-EU suppliers. Our model distinguishes and evaluates the three terms of an optimum tax: budget, environment and strategy. Their values depend on technological data (output) and habits (consumption)...

We model an economy that alternates randomly between abundance and scarcity episodes. We develop an original method to characterize in detail the structure of the Markovian competitive equilibrium. Accumulation and drainage of stocks are the main focuses. Economically appealing comparative...

In this paper, we discuss how fraud losses impact the price structure chosen by a monopolistic payment platform, if merchants can invest in fraud detection technologies. We show that liability rules bias the structure of the prices charged by the platform to consumers and merchants with respect...

This paper investigates the links between price returns for 25 commodities and stocks over the period from January 2001 to November 2011, by paying a particular attention to energy raw materials. Relying on the dynamic conditional correlation (DCC) GARCH methodology, we show that the...

This paper presents a very simple characterization of the technological choices underlying M-form and U-form organizations. We first show that the externalities within a function favour the M-form, which gives higher profit, higher output level and lower prices than the U-form. The major...

This paper analyzes the role of private storage in a market for a commodity (e.g. natural gas) whose supply is subject to the threat of an irreversible disruption. We focus on the medium term in which seasonality of demand and exhaustibility can be neglected. We characterize the price and...

The aim of this paper is to investigate the determinants of the carbon price during the two phases of the European Union Emission Trading Scheme (EU ETS). More specifically, relying on daily EU allowance futures contracts, we test whether the carbon price drivers identified for Phase I still...

In this paper, we discuss how fraud liability regimes impact the price structure that is chosen by a monopolistic payment platform, in a setting where merchants can invest in fraud detection technologies. We show that liability allocation rules distort the price structure charged by platforms or...

This paper analyzes the role of private storage in a market for a commodity (e.g. natural gas) whose supply is subject to the threat of an irreversible disruption. We focus on the medium term in which seasonality of demand and exhaustibility can be neglected. We characterize the price and...
