The paper looks at the genesis of innovation in the EU regions in ordre to shed light on the link between innovative inputs (R&D and Human Capital) and the genesis of economically valuable knowledge. The 'traditional' regional Knowledge Production Function (KPF) is innovatively developed in...

The specialization patterns of metropolitan areas are crucial in characterizing the effects of economic integration in Europe. This paper aims to provide and estimate an econometric model that explains both sectoral specialization and sectoral dissimilarity, measured with the GINI and the...

In this paper I discuss the fact that economists define optimal IP rights as a continuum of options in three dimensions: height, breadth and length. At the operational level we see the impossibility of multiplying rights indefinitely (due to prohibitive transaction costs), as well as the use of...

L'analyse du cadre institutionnel existant et des paramètres physiques et naturels qui peuvent influer sur la régulation des émissions azotées dans les eaux de surface est essentielle pour juger de l’efficacité des instruments. Cela nous a amené à retenir un modèle de régulation qui...

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...
