We argue analytically that many commonly used models of pollution-generating technologies, which treat pollution as a freely disposable input or as a weakly disposable and null-joint output, may generate unacceptable implications for the trade-offs among inputs, outputs, and pollution. We show...

We characterize Pareto-improving and equilibrium-preserving policy reforms in a second-best (Diamond/Mirrlees) world with a consumption externality. A counterintuitive finding is that, starting from an initial equilibrium with no direct quantity control on the externality, it is possible that...

Starrett (1972) [33] and Boyd and Conley (1997) [7] approaches to externality modeling are unified by distinguishing between producible and nonproducible public commodities. Nonconvexities are associated with detrimental producible public commodities but not with nonproducible public commodities...

We propose a set of necessary and sufficient conditions for the environmental Kuznets curve (EKC) phenomenon in a general model that permits non-smooth preferences and feasible sets and corner solutions for welfare maximisation. These conditions pertain to the relationship between the sets of...
