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...

The concept of translation homotheticity is introduced and defined. It is demonstrated that translation homotheticity is necessary and sufficient for: disposable surplus to be independent of the reference utility, Luenberger's compensating and equivalent benefits to be independent of the...
