Cette note étudie comment un choc de demande exogène, tel que des aides publiques, influence le potentiel d’exclusion contenu dans les effets d’apprentissage. Nous construisons un modèle de duopole à deux périodes dans lequel l’accroissement de production par une entreprise à la première période...

Weed control in the U.S. Midwest has become increasingly herbicide-centric due to the adoption of herbicide-tolerant (HT) crops in the 1990s. That integrated weed management (IWM) practices, including ecological and mechanical controls, are scarcely used is concerning. IWM would be a more...

We study a generous program to promote the adoption of solar photovoltaic (PV) systems through subsidies on future electricity production, rather than through upfront investment subsidies. We develop a tractable dynamic model of new technology adoption, also accounting for local market...

Letter volumes in countries with advanced broadband networks have been in decline since the early to mid-2000s while, more recently, parcel volumes have started to grow quite rapidly. The main drivers of these trends, namely the substitution of physical letters with electronic modes of...

We study a model of two-player, zero-sum, stopping games with asymmetric information. We assume that the payoff depends on two independent continuous-time Markov chains, where the first Markov chain is only observed by player 1 and the second Markov chain is only observed by player 2, implying that...

To model multivariate, possibly heavy-tailed data, we compare the multivariate normal model (N) with two versions of the multivariate Student model: the independent multivariate Student (IT) and the uncorrelated multivariate Student (UT). After recalling some facts about these distributions and...

Cross-subsidization arises naturally when firms with different comparative ad- vantages compete for consumers with diverse shopping patterns. Firms then face a form of co-opetition, being substitutes for one-stop shoppers and complements for multi-stop shoppers. Competition for one-stop shoppers...

This paper addresses the waves of mass killings recently perpetrated by individuals with a weak or nonexistent ideological motivation, whose acts either appear to contradict their purported political cause or are admittedly driven by a quest for notoriety. Examples range from killers who have been...
