The more altruist agents regarding the transmitted environment are qualified of ecologists, whereas the others, less...

The question at stake is that of the theoretical representation of marketable permits. The setting up of such markets to regulate pollution problems is justified by constant reference to the efficiency of market coordination. Indeed, Montgomery established in 1972 the existence of an efficient...

Previous research has extensively studied the gap between environmental or social concern, and behaviour. However, measuring environmental or social dimension valuation remains challenging. This paper therefore fills this gap by measuring fair trade and organic labels valuation, using an...
