Protection des habitats d'espèces menacées en terres privées: analyse d'instruments et de la politique canadienne
Barla, Philippe; Doucet, Joseph A.; Saphores, Jean-Daniel M. - Département d'Économique, Université Laval - 1999
The preservation of biodiversity requires the protection of endangered species' habitats. In Canada, approximately 60% of these habitats are located on private lands. We start by analysing the obstacles to the protection of endangered species' habitats, with special attention to the compensation...

Non-Deteriorating Choice
BOSSERT, Walter; SPRUMONT, Yves - Département de Sciences Économiques, Université de … - 2001
We analyze an alternative to the standard rationalizability requirement for observed choices by considering non-deteriorating selections. A selection function is a generalization of a choice function where selected alternatives may depend on a reference (or status quo) alternative in addition to...

What Is a Commody? Two Axiomatic Anwers
SPRUMONT, Yves - Département de Sciences Économiques, Université de … - 2001
We identify conditions under which preferences over sets of consumption opportunities can be reduced to preferences over bundles of "commodities". We distinguish ordinal bundles, whose coordinates are defined up to monotone transformations, from cardinal bundles, whose coordinates are defined up...

A Dynamic Game of Emissions Pollution with Uncertainty and Learning
Masoudi, Nahid; Santugini, Marc; Zaccour, Georges - Centre Interuniversitaire sur le Risque, les Politiques … - 2015
We introduce learning in a dynamic game of international pollution, with ecological uncertainty. We characterize and compare the feedback non-cooperative emissions strategies of players when the players do not know the distribution of ecological uncertainty but they gain information (learn)...

Strategic Interactions in a One-Sector Growth Model
Fesselmeyer, Eric; Mirman, Leonard J.; Santugini, Marc - Institut d'Économie Appliquée, HEC Montréal (École … - 2013
We study the effect of dynamic and investment externalities in a one-sector growth model. In our model, two agents interact strategically in the utilization of capital for consumption, savings, and investment in technical progress. We consider two types of investment choices: complements and...

What is ambiguity?
AMARANTE, Massimiliano - Département de Sciences Économiques, Université de … - 2014
The concept of Ambiguity designates those situations where the information available to the decision maker is … SEU theory, and shows that their mathematical properties are the formal counterpart of the intuitive idea of insufficient … unambiguous situations. Finally, the paper shows that behavior not conforming to SEU theory must emerge in correspondence of …
