Production externality and productivity of labor.

In this paper we consider two imperfectly competitive industries, with the polluting emissions from one industry harming the productivity of labor in the other. The polluting industry has to pay an environmental tax chosen by the government. In this framework, we analyze how the different organizational structure adopted by workers affect the environmental tax set by the government, total pollution emissions from the polluting industry and the productivity of workers in the industry that suffers the externality. We obtain that this depends on the degree to which pollution emissions from the polluting industry affects the marginal product of labor in the other industry.Production externality, productivity of labor, environmental taxes, imperfect competition, unionized labor.

Strategic Delegation and Semipublic Firms

By considering a mixed oligopoly and considering that public firms are less efficient than private firms, White (2001) shows that if private firms hire managers then the public firm does not do so. We show in this paper that if we consider that a private firm competes with a firm that is owned jointly by both the private and public sectors (a semipublic firm) and that all the firms are equally efficient, then in equilibrium both firms hire managers.Mixed duopoly, Semipublic Firms, Managerial incentive contracts, Cournot competition

Cost-saving production technologies and partial ownership

This work analyzes the incentives to acquire cost-saving production technologies when cross-participation exists at ownership level. We show that cross-participation reduces the incentives to adopt the cost-saving production technology.

La réforme des forces de police au Canada : les tensions entre la sécurité des citoyens, les libertés fondamentales et le fédéralisme

Cet article envisage les politiques en matière de sécurité citoyenne et la réforme des forces de police au Canada pendant les 25 dernières années. La Charte canadienne des droits et libertés a établi dans l’article 7 la garantie à la « sécurité de la personne ». La poursuite de cette garantie a supposé, d’une part, une tension entre la décentralisation, le désengagement de l’État et le rôle de la police et, d’autre part, une tension entre son mandat de préserver l’ordre public, entendu comme la sauvegarde de l’État, et la protection des citoyens. Même si ces tensions se révèlent problématiques, elles n’ont pas empêché que le Canada soit un pays sûr dont le taux de criminalité est bas et où règne un important sentiment de sécurité parmi les citoyens.This article looks at policies concerning citizen security and reform among Canada's police forces during the last twenty-five years. Article 7 of the Canadian Charter of Rights and Freedoms established a guarantee of "security of the person". Pursuit of this guarantee has supposed, on one hand, a tension between decentralization, withdrawal of the State, and the role of police, and on the other hand, a tension between the Charter's mandate to preserve public order, understood as the safeguard of the State, and the protection of citizens. Even if revealed as problematic, these tensions did not prevent Canada from being a confident country with low crime rates and a heightened sense of security among its citizens
