To market a new network technology effectively, manufacturers need to understand the structure and size of network effects associated with the product. If consumers' surplus from adoption depends positively on the number of interconnections in the network, early adopters may need to be...

This paper aims to investigate the transition to a new energy system based on hydrogen in the European liberalized framework. After analyzing the literature on the hydrogen infrastructure needs in Europe, we estimate the size and scope of the transition challenge.We take the theoretical...

Depuis quelques années, les réseaux sociaux et les usages qu'ils nourrissent ont pris une place significative au sein de la galaxie Internet. Parmi ces réseaux, ceux qui pratiquent la gratuité pour les utilisateurs finals n'ont pas encore stabilisé leur modèle économique et ce, malgré...

We characterize the equilibrium of a game in vertically differentiated market which exhibits network externalities. There are two firms, an incumbent and a potential entrant. Compatibility means in our model that the inherent qualities of the goods are close enough. By choosing its quality, the...

Big airports profits are more and more often coming from commercial activities such as retailing. However, commercial services are relatively far from the original mission of the airport : providing airlines with aviation services such as ground handling, terminal management or airside...

This paper studies optimal pricing in networks in the presence of local consumption or price externalities. It analyzes the relation between prices and nodal centrality measures. Using an asymptotic approach, it shows that the ranking of optimal prices and strategies can be reduced to the...

Empirically the diffusion of competing technologies most often displays either "lock-in" to a quasi-monopoly or apparent turbulence but rarely stable market-sharing. In contrast with widespread views, we show that, first, unbounded increasing returns are neither necessary nor sufficient to lead...

Transboundary pollution is a particularly serious problem as it leads people located at regional borders to disproportionately suffer from pollution. In China, where the environmental policy is decentralized and where environmental conflicts between provinces have occurred several times,...
