This document seeks to lay the groundwork for a government policy on free and open source software. We briefly characterize the extent of the open source software phenomenon. We analyse its pros and cons for the government, in its role as both an engine of economic development and a large user...

Ce texte vise à circonscrire les fondements d'une politique gouvernementale à l'égard du logiciel libre et ouvert (open source software). Nous caractérisons brièvement l'ampleur du phénomène du logiciel libre et nous en analysons les avantages et inconvénients pour le gouvernement tant...

In this paper, we propose a design for an an economically efficient, optimized, centralized, multi-lateral, periodic commodity market that addresses explicitly three issues: (i) substantial transportation costs between sellers and buyers; (ii) non homogeneous, in quality and nature, commodities;...

Our objective in this paper is to illustrate and better understand the unavoidable arbitrage between incentives and flexibility in contexts of asymmetric information and to characterize the general features of an appropriate response to this challenge. We show that procedures and institutions in...

This paper presents the theory of sequential auctions when participants desire more than one unit. The theoretical predictions are compared to experimental data. We estimate structural models which presume that participants' bids are drawn from some stochastic processes. The observed behavior...

In a general framework with independent private values of the bidders, we propose a game, with a simple economic interpretation, that allows implementing the optimal auction outcome when the seller ignores the distributions of the different bidders' valuations. In this robust or detail-free...

In this paper, we first review in this paper some general principles and fundamental facts and issues which remain at the heart of the movement towards deregulation, restructuring and privatization in network industries in general and in the electricity industry in particular. We then proceed...
