Recyclage et externalités environnementales : Faut-il subventionner les activités de récupération recyclage ?
This paper considers recycling in a general equilibrium model. It is shown that recycling should be subsidized if recycling costs are high, as an incentive to recycle all of the available waste. This tax incentive should vanish if recycling is profitable enough. In this case, recycling should even be taxed, in order to make the competitive equilibrium be an optimal allocation. We conclude also that, if recycling is efficient enough, it allows to internalize environmental externalities. In this case, recycling replaces a tax instrument.
