In some data envelopment analysis (DEA) applications, some inputs of DMUs have negative values with positive cost. This paper generalizes the global cost Malmquist productivity index to compare the productivity of different DMUs with negative inputs in any two periods of times under variable returns to scale (VRS) technology, and then the generalized index is decomposed to several components. T...

BACKGROUND Norwegian government policy is to increase the supply of psychiatric services to children and young persons, both by increasing the number of personnel, and by increasing productivity in the psychiatric outpatient clinics. Increased accessibility is observed for the last years, measured as the number of children receiving services each year. AIMS OF THE STUDY The paper aims to esti...

This paper investigates the total factor productivity (TFP) performance of NWFP agriculture crop subsector from 1970 to 2004. It identifies the sources of growth of TFP growth and assesses TFP growth changes in agriculture crop sub-sector. Data envelopment analysis (DEA) approach is used to estimate the changes in the production frontier. The Malmquist productivity index has decomposed total fa...

Nondiscretionary environmental inputs are critical in explaining relative efficiency differences and productivity changes in public sector applications. For example, the literature on education production shows that school districts perform better when student poverty is lower. In this paper, we extend the nonparametric approach to decompose Malmquist productivity index suggested by Färe et al....
