In this study we use data envelopment analysis to decompose the overall economicefficiency of a sample of ethanol plants into three subcomponents: technical efficiency, allocative efficiency and a new component we call marketing efficiency. The relative importance of these sources of efficiency...

This decomposition allows us to evaluate the channels through which different plant characteristics affect plant...
