We present a dynamic model of factor demands based on expected discounted costs min-imization. While making only very mild assumptions on expectations and technology, we are able to establish a duality relationship between contemporary factor demands and the technology, and we provide formula...

In existing papers on dynamic incentive contracts, the dynamic structure of the principal-agent relationship arises exclusively from the ability of the principal to learn about the hidden information over time. In this paper we deal with a different source of dynamics, which is considered...

Forests emit and absorb carbon. Although the portion of anthropic climate change that can be attributed to forestry activities and land use is small relative to the contribution of fossil fuels consumption, it is by no mean negligible. The role that the forest may play as a sink or a source of...

Using nonparametric estimation techniques adapted from Guerre et al. [2000], we infer cost distributions and informational rents, from 666 snow removal contracts offered for tender by the City of Montreal. Our results are compatible with standard received theory of competitive auctions: there is...

We present a dynamic model of factor demands based on a contemporary cost function and a dynamic version of Shepard's lemma. While making only very mild assumptions on expectations and technology, we are able to present a complete characterization of the factor demand system and the contemporary...

Nous présentons un modèle dynamique de demande de facteurs de production basé sur un comportement de minimisation de l'espérance des coûts cumulatifs actualisés. Sous des hypothèses peu restrictives sur les anticipations et la technologie, nous établissons une relation de dualité entre...

This paper revisits the tragedy of the commons when agents have different capabilities in both production and encroachment activities, and can allocate their time between them. Under fairly general assumptions on production and encroachment technologies, an individual's expected income is convex...

We study a simple duopoly model of preemption with multiple investments and instantaneous Bertrand competition on a market of finite size driven by stochastic taste shocks. Different patterns of equilibria may arise, depending on the importance of the real option effect. If the average growth...
