This note establishes that two propositions in the theory of private common agency by Laussel and Le Breton (J. Econ. Theory 100 (2001) 93) extend to a larger class of games, in which each principal's gross monetary payoff does not depend exclusively on the quantities she receives. A new result...

Due to meteorological factors, the distribution of the environmental damage due to climate change bears no relationship to that of global emissions. We argue in favor of offsetting this discrepancy, and propose a “global insurance scheme” to be financed according to countries’...

We characterize sequential (preemption) and simultaneous (coordination) equilibria, as well as joint-value maximizing (cooperation) solutions, in a model of investment timing allowing for externalities in both flow profits and investment costs. For two ex-ante symmetric firms, either preemption...

In this paper, we study how maritime ferry industries should be regulated. This is a fundamental issue in so far as maritime transport between islands and mainland is a service of general interest. We argue that the policy design crucially depends on the goals the collectivity pursues (pure...

Due to meteorological factors, the distribution of the environmental damage due to climate change bears no relationship to that of global emissions. We argue in favor of offsetting this discrepancy, and propose a “global insurance scheme” to be financed according to countries’...

This paper studies a liberalized postal market where entrants may offer end-to-end products or concentrate on one of the segments of the network. Absent effective bypass, entry does not appear to be a serious financial threat to the incumbent, even when the products are perfect substitutes. This...

We observe that a Pigovian climate policy need not exact full payment of the social cost of carbon upon emission to yield optimal incentives. Following this insight, we propose the creation of a carbon liabilities market to address climate change. Each period, countries would be made liable for...

[fre] Structure optimale des prix dans le secteur postal. . L'objectif de cet article est d'étudier la structure optimale des prix dans le secteur postal lorsqu'une partie des clients peut décider de ne pas utiliser la totalité du réseau de l'opérateur. Nous comparons la remise optimale...

In a real option model, we show that the standard analysis of vertical relationships transposes directly to investment timing. Thus, when a firm undertaking a project requires an outside supplier (e.g., an equipment manufacturer) to provide it with a discrete input to serve a growing but...
