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...

This paper introduces a decomposition of the Malmquist productivity index into component indexes. The motivation is to derive an analogue of the decomposition of the Tornqvist index into productivity and quality change provided by Fixler and Zieschang (1992) to the Malmquist index. Since we...

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...

The purpose of this chapter is to suggest a general framework for assessing the efficiency of health care in general, and health care interventions specifically. We begin with a three-pronged overview of assessing performance in health care which begins with what we call the budget or cost side...
