This paper examines how the marginal CO2 abatement costs vary throughout stages of economic development, and how these variations may be related to the Environmental Kuznets Curve (EKC) hypothesis. By assuming the existence of a technological link between production of desirable outputs and...

In this paper, we present an alternative analysis framework to evaluate the effects of technology heterogeneities and undesirable output on environmental efficiency measurement. The proposed framework combines the directional distance function and a meta-frontier analysis. It can be used to...

This paper analyzes productivity with a directional distance function model by investigating convexity and non-convexity in the Chinese banking sector. Two primary findings are summarized. First, there is a distinct change in productivity between large versus small banks and public versus...
