Renewable resource management with environmental prediction Variations in environmental conditions affect renewable resource growth. The ability to predict such variations is improving, providing scope for improved management. We generalize a common stochastic stock recruitment model to explore how optimal management changes with environmental prediction. We obtain three main results. First, while it might seem that a prediction of adverse future conditions should lead to more conservative management, the opposite may be true. Second, optimal management requires only a one‐period‐ahead forecast, suggesting forecast accuracy is more important than forecast lead time. Finally, we derive conditions on environmental fluctuations guaranteeing positive optimal harvest in every period. Gestion d'une ressource renouvelable quand on prédit les conditions futures de l'environnement. Les variations dans les conditions de l'environnement affectent la croissance de la ressource renouvelable. La capacitéà prévoir ces variations s'améliore et ouvre la possibilité d'améliorer la gestion de la ressource. Les auteurs utilisent un modèle de ressource renouvelable avec croissance stochastique et obtiennent trois résultats. D'abord, alors qu'il peut sembler que des prévisions pessimistes de conditions difficiles dans l'avenir peuvent conduire à une gestion plus conservatrice, le contraire peut être vrai. Ensuite, la gestion optimale requiert seulement une prédiction pour la prochaine période: voilà qui suggère qu'il est plus important d'avoir une prévision exacte que d'avoir des prévisions à plus long terme. Enfin, on développe les conditions pour les fluctuations de l'environnement qui garantissent une récolte positive optimale à chaque période.

Consumer‐benefiting exclusive territories Abstract. I investigate the effect of exclusive territories, which are typical vertical controls imposed by upstream firms. Using shipping spatial models, I consider an industry that consists of many independent local markets. An upstream monopolist restricts competition between downstream firms using exclusive territories. I find that exclusive territories reduce the prices of final products in all local markets in quantity‐setting competition. In price‐setting competition, they raise prices in half the local markets, reduce them in other markets, and also reduce the total consumer surplus. JEL classification: L42, R32

The wage gap between Francophones and Anglophones: a Canadian perspective, 1970–2000 Abstract. The wage gap between Francophone and Anglophone men from 1970 and 2000 fell by 25 percentage points within Quebec, but only by 10 points Canada‐wide, largely because the wages of Quebec Anglophones fell by 15 points relative to other Canadian Anglophones. Accordingly, the Canadian measure of the Francophone gap better reflects the changing welfare of Francophones than the Quebec measure. Over half of the reduction in the Canadian Francophone wage gap is explained by rising Francophone education levels. In Quebec, the declining number and relative wages of Anglophone workers is best explained by a falling demand for English‐speaking labour.
