The materials balance condition is a fundamental adding up condition, which essentially says that �what goes in must come out�. In this paper we argue that a number of the recently developed methods of incorporating pollution measures into standard productive efficiency models are...

It has often been argued that the results of efficiency analyses in health care are influenced by the modelling choices made by the researchers involved. In this paper we use meta-regression analysis in an attempt to quantify the degree to which modelling factors influence efficiency estimates....

The main objectives of this paper are to measure total factor productivity (TFP) growth in the electricity supply industry in Peninsular Malaysia from 1975 to 2005 and to assess the impact of private entry reforms upon TFP in this industry. Prior to 1995, a government-linked,...
