This study proposes a new theoretical framework - modeling the joint production of good and bad outputs - to determine the association between pollution abatement activities and changes in traditional productivity growth. After using the joint production model to investigate the theoretical...

This study models the joint production of good and bad output production and calculates traditional productivity when bad output production is regulated and when it is unregulated. We apply this model to data for U.S. coal-fired electric power plants for 1985-1995 and compare rates of...

We review nonparametric estimation of efficiency and productivity, by which we mainly mean activity analysis, or data envelopment analysis (DEA). The review covers topics that we hope will be of special interest to those doing research in the realm of agriculture. We also include a brief...
