The modified data envelopment analysis (DEA) model used in this study models the joint production of good and bad outputs in order to determine the relative importance of factors associated with changes in SO2 emissions by manufacturing industries in the United States. This new decomposition model calculates changes in emissions associated with changes in technical efficiency, technical change, input growth, and changes in the emission intensity. This study finds that the decline in emissions between 1970 and 1996 is primarily associated with industries switching to processes that produce less SO2 per dollar of output.
