This paper studies the links between non-renewable and intermittent renewable energy sources in the production of electricity. We argue that the relationship between the price of natural gas and investments in solar and wind capacity is represented by a bell-shaped curve, as opposed to being...

In this paper, we analyze the strategic function of gas storage focusing on how gas storage decisions impact competition between gas companies on both spot and downstream markets. Using a two-tier oligopolistic structure, we first show that gas storage is actually used strategically even in a...

This paper examines a model of competition between two types of health insurers: Managed Care Organizations (MCOs) and Conventional Insurers". MCOs vertically integrate health care providers and pay them at a competitive price, while conventional insurers work as indemnity plans and pay the...

The aim of this paper is to explore the effectiveness of asymmetric regulation, which allows a new mobile network operator to set higher termination rates than the incumbent operator. We assume that there are two market segments: one in which operators compete on equal terms, with a new...

[fre] Cet article étudie la question de l’articulation entre réglementation et politique de la concurrence dans le cadre de l’économie d’Internet. Nous nous intéressons en particulier au contrôle du pouvoir de marché des backbones. Pour cela, nous construisons un jeu en deux étapes....

This paper studies the interplay between network investment and content quality on the Internet, and investigates the implications to the net neutrality regime. We assume a model in which a network operator provides access to consumers and content providers. The network operator offers two...

We study horizontal mergers on two-sided markets between horizontally differentiated platforms. We provide a theoretical analysis of the merger's price effect based on the amount of cost savings it generates, the behavior of outsider platforms, and the size of cross-group network effects. We...

This paper studies the links between renewable and non-renewable intermittent energy sources in the production of electricity. More precisely, we argue that the relationship between the natural gas price and capacity investments in solar and wind power energy is far from univocal. We find that...
