Face to the ecological crisis, societies move towards the consideration that the environment is a common good, which is used in incompatible way. When firms produce private goods, they also produce negative external effects damaging environmental common goods.

Les données permettant d’analyser la conflictualité sont peu nombreuses, et souvent lacunaires, pour deux raisons principales : le faible intérêt marqué pour ce domaine jusqu’aux années 2000 et la forme complexe prise par les conflits (tribunaux, médiatisation, violence…), ce qui interdit l’usage d’une seule variable représentative. Le chercheur do...

The presence of nearby public facilities has an impact on real-estate values; for this reason, the market may reasonably anticipate that public infrastructure projects will affect house prices.

Nous proposons de montrer comment les dimensions conflictuelles, qui sont à l’origine de bien des oppositions locales et naissent souvent au sujet de décisions publiques jugées injustifiées, contribuent à l’élaboration de la décision publique et y jouent un rôle non négligeable, en matière de bancs d’essais de l’action publique. Le travail se focal...
