Productivity Index (productivity + index)
Selected AbstractsAccounting for quality in the measurement of hospital performance: evidence from Costa RicaHEALTH ECONOMICS, Issue 7 2007Pablo Arocena Abstract This paper provides insights into how Costa Rican public hospitals responded to the pressure for increased efficiency and quality introduced by the reforms carried out over the period 1997,2001. To that purpose we compute a generalized output distance function by means of non-parametric mathematical programming to construct a productivity index, which accounts for productivity changes while controlling for quality of care. Our results show an improvement in hospital performance mainly driven by quality increases. The adoption of management contracts seems to have contributed to such enhancement, more notably for small hospitals. Further, productivity growth is primarily due to technical and scale efficiency change rather than technological change. A number of policy implications are drawn from these results.

[source] Evaluating the efficiency of a small hotel chain with a Malmquist productivity indexINTERNATIONAL JOURNAL OF TOURISM RESEARCH, Issue 3 2005Carlos Pestana Barros Abstract By applying data envelopment analysis (DEA) a two-stage procedure is followed to evaluate the determinants of efficiency of a Portuguese public-owned hotel chain, Enatur for the period 1999 to 2001. In the first stage the paper estimates the Malmquist index and breaks it down into technical efficiency and technological change. In the second stage, a Tobit econometric model, designed to relate efficiency scores, along with other managerial and contextual variables, is used to identify the efficiency drivers. The implications of this study for managerial purposes are then discussed. Copyright © 2005 John Wiley & Sons, Ltd. [source] Accounting for Air Pollution Emissions in Measures of State Manufacturing Productivity GrowthJOURNAL OF REGIONAL SCIENCE, Issue 3 2001Rolf Färe A Malmquist-Luenberger productivity index is employed to account for both marketed output and the output of pollution abatement activities of U.S. state manufacturing sectors for ,1986. The index allows us to decompose the change in productivity into measures of change in efficiency and technical change. By accounting for the change in emissions, average annual productivity growth is 3.6 percent, whereas it is 1.7 percent when emissions are ignored. We also find adjusted productivity growth improved after 1977, and "Frost Belt" states with rapidly growing manufacturing sectors have significantly higher rates of productivity growth than "Sun Belt" states with slow growing manufacturing sectors. [source] A parsimonious crop-water productivity index: an application to BrazilAREA, Issue 1 2009Marco P Maneta Reducing poverty in rural areas of developing countries requires sustained and sustainable increases in agricultural water productivity. However, aside from traditional measures of precipitation, little is known about water available to farmers or how productively they use it. We present a crop-water productivity index (a ratio of the value of annual crop production to a dimensionless potential water availability index) for large water basins using readily available low-resolution data. The index is transferable, permits direct inter-basin comparisons, and is simple to calculate. We calculate the index for each municipality in the São Francisco river basin in Brazil. No clear patterns linking water availability and value of agricultural output are evident, even though clusters of municípios with high- and low-crop-water productivity emerge, and the former may be useful in guiding policies aimed at increasing water productivity. Finally, analyses of the effects of information uncertainty on the crop-water productivity index suggest that the returns to agricultural investments in certain places in the São Francisco river basin are more risky than others. Improvements in data quality and quantity can help refine estimates of the index and reduce their uncertainty. [source] | ||||||||||
