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...

The reduced form approaches that are commonly adopted in the literature to model emission-generating technologies (EGTs) do not distinguish between emission-causing and non-emission causing goods in production. We provide a new set of axioms to describe EGTs. Technologies that satisfy these...

A by-production-cum-preference based approach is adopted to study the relation between national income and environmental quality under non-cooperative behaviour. While emission is an inferior good for richly endowed economies, it is a normal good for the developing economies. With increases in...
