A Malmquist-Luenberger productivity index is employed to account for both marketed output and the output of pollution abatement activities of U.S. state manufacturing sectors for 1974-1986. The index allows us to decompose the change in productivity into measures of change in efficiency and...

In this paper we study environmental efficiency within a pollution generating technology. Pollutants, or bads, are explicitly modeled by imposing technology properties of disposability and null-jointness. With data on firms from Swedish manufacturing, we investigate the potential to reduce...
