Résumé. Dans cet article nous proposons une approche originale basée sur les techniques de data mining pour l’extraction des connaissances par fusion floue de données.

Mandates are policy tools that are becoming increasingly popular to promote renewable energy use. In addition to mitigating the pollution externality of conventional energy, mandates have the potential to promote R&D investments in renewable energy technology. But how well do mandates perform as innovation incentives? To address this question, we develop a partial equilibrium model with endogen...

Under a Maximin objective, if the elasticity of part...
