In developing countries, traditional social obligations often press rich individuals to share their income. In this paper, we posit a "model of social pressure" in which people can sign binding financial agreements amongst themselves, thereby forming coalitions. These financial agreements may...

The paper examines the implementation of Bayesian allocation rules that satisfy non-negative ex post payoffs for one player in a two-players bilateral asymmetric information setting. It focuses on sequential mechanisms in which players communicate in turn among themselves. First, it shows that,...

The paper starts with the wide variability of nonpoint water nitrogenous pollution generated by agriculture. This variability depends especially on climate, soil types and farming systems. Our interdisciplinary researches, mainly based on two sites in France, show that space and time...

The report contains two sections. The first analyses the incentive mechanisms in agricultural biotechnologies; it begins with a theoretical and historical analysis. The co-evolution of scientific paradigms and IPR in agricultural biotechnologies is then studied – in particular, the coexistence...

We propose a model where imperfect matching between firms and workers on local labor markets leads to incentives for spatial agglomeration. We show that the occurence of spatial agglomeration depends on initial size differences in terms of both number of workers and firms. Allowing for dynamics...

A group of agents enjoy concave and single-peak benefit functions from consuming a shared resource. They also value money (transfers). The resource is scarce in the sense that not everybody can consume its peak. The paper characterizes the unique (resource and money) allocation that is...

Owing to increasing environmental concerns the current trend is to bend technical production systems in order to adapt them to the specific characteristics of the milieu and diversify them. Inherent to such dynamics is the issue of how to design the accompanying environmental policies....

This paper considers environments in which several agents (countries, farmers, cities) share water from a river. Each agent enjoys a concave benefit function from consuming water up to a satiation level. Noncooperative extraction is typically inefficient and any group of agents can gain if they...

The paper explores project management in action in a large public research organisation – NLAT which decided to change its internal organisation from team-based to project-based organisation a few years ago. A systematic and comparative analysis of 8 projects reveals that adherence to the ISO...

We investigate the consequences of assuming "private" communication between the principal and each of his agents in an otherwise standard mechanism design setting.Doing so simplifies significantly optimal mechanisms and institutions. Moreover, it restores continuity of the principal's payoff and...
