The methods implemented in the program are based upon the work of Rolf Fare Shawna Grosskopf and their associates. Three principal options are available in the computer program. The first involves the standard CRS and VRS DEA models that involve the calculation of technical and scale efficiencies which are outlined in Fare Grosskopf and Lovell 1994 . The second option considers the extension of these models to account for cost and allocative efficiencies. These methods are also outlined in Fare et al 1994 . The third option considers the application of Malmquist DEA methods to panel data to calculate indices of total factor productivity TFP change technological change technical efficiency change and scale efficiency change. These latter methods are discussed in Fare Grosskopf Norris and Zhang 1994 . All methods are available in either an input or an output orientation with the exception of the cost efficiencies option . 1. INTRODUCTION This guide describes a computer program which has been written to conduct data envelopment analyses DEA . DEA involves the use of linear programming methods to construct a non-parametric piecewise surface or frontier over the data so as to be able to calculate efficiencies relative to this surface. The computer program can consider a variety of models. The three principal options are 1. Standard CRS and VRS DEA models that involve the calculation of technical and scale efficiencies where applicable . These methods are outlined in Fare Grosskopf and .
