En esta investigación se realizó un análisis comparativo de los cambios en la productividad de las entidades federativas de México, durante el período 2005-2010. Para estimar la productividad se utilizó la metodología basada en el Análisis Envolvente de Datos (DEA), bajo el Índice de Productividad de Malmquist (IPM), empleando como producto al PIB estatal y como insumos al capital y mano de obra. Los resultados muestran un descenso general en la productividad del 2005 al 2009, con una recuperación en el 2010; esto se debió principalmente al componente de cambio tecnológico, más que a cambios en la eficiencia técnica. Los desequilibrios regionales principalmente del cuarto período que reflejan los resultados del IPM coinciden con la crisis financiera del... |

Efficiency measurement has been one of the most extensively explored areas of health services research over the past two decades. Despite this attention, few studies have examined whether a providers efficiency varies on a monthly, quarterly or other, sub-annual basis. This paper presents an empirical study that looks for evidence of seasonal inefficiency. Using a quarterly panel of general, acute-care hospitals from Washington State, we find that hospital efficiency does vary over time; however, the nature of this dynamic inefficiency depends on the type of efficiency being measured. Our results suggest that technical and cost efficiency vary by quarter. Allocative and scale efficiency also vary on a quarterly basis, but only if the data are jointly... |

This paper provides an assessment of the extent to which targets set by a public authority are achieved by its operational units. A rare DEA framework and its subsequent Malmquist indices are applied on data comprising 19 units over a four year period of 1996 to 1999. The mean efficiency scores by which targets are achieved across the sample years are moderate, in the range 0.81 to 0.93. Average productivity progress across the sample years has been 26 percent. The results illustrate the usefulness of DEA even when there are no inputs and the decomposable Malmquist index for productivity is an asset in exploring causes of productivity growth. |

The milk market changes in Brazil, occured in the last few decades, have challenged the milk producers, especially the smaller ones in relation to milk quality improvement, the reduction of production costs, the adoption of modern practical management technologies and efficiency and productivity gain. The economic sustainability of the producers depends, in great measure, on their success in responding positively to these challenges. This work has aimed to evaluate the technical and economical efficiency of the family dairy production in settlement projects of agrarian reform in the city of Unaí-MG. Information on the production of sixteen producers were collected during an eleven-month period. For evaluating the efficiency, it was used Data Envelopment... |

Changes and trends in farm productivity have been of intense interest to many involved with agriculture. This study used data envelopment analysis (DEA) to estimate the output-oriented Malmquist total factor productivity (TFP) index from panel data for 1993-2006 for farms in Southern Minnesota. Bootstrap methods were used to estimate confidence intervals for the productivity, efficiency change and technical change indices. The model included three inputs (labor, land and immediate expenditures) and six outputs (corn, soybean, milk, hog, beef, and nonfarm income). Productivity growth was found to be positive during the period, with an average annual productivity growth of 6.6 percent. However, TFP growth has been slowing down in recent years and indeed... |

Farm sustainability is becoming an increasingly important issue to European agriculture. However, fertilizer leaching to groundwater is still a major concern for Greek agriculture. The impact on the maximum potential short-run profit and yield, when fertiliser application dose is limited to certain point, was examined, using Data Envelopment Analysis (DEA). Spring potato farmers were found to apply rather high doses of chemical fertiliser, which poses high potential risk for nitrate and phosphorus leaching to groundwater. However, restricting nitrogen application to the doses recommended by agronomists would imply only little economic and yield sacrifices on potato farms,but resulting to significant reduction to potential environmental risk. |
