O Programa de Aquisição de Alimentos (PAA) é uma política pública voltada à comercialização dos produtos agrícolas da agricultura familiar, implementada em 2003 no Brasil. Objetivou-se analisar a eficiência no uso dos recursos do PAA na modalidade Compra com Doação Simultânea (CDS-PAA) nos estados brasileiros participantes no ano de 2011, utilizando a metodologia DEA (Data Envelopment Analysis). Na análise, utilizou-se como inputs o número de agricultores familiares ocupados por estado no ano de 2006 e o número de agricultores familiares participantes do CDS-PAA por estado no ano de 2011, e como outputs utilizaram-se o número de pessoas beneficiadas pelo CDS-PAA por estado, a quantidade em quilogramas (kg) de produtos adquiridos pela modalidade e o valor... |

The transition of East German agriculture led to major structural adjustments that showed some very particular phenomena. For instance, most of the successors of the former agricultural production cooperatives (LPGs) make slight losses and they operate at a higher employment level than new and re-established farms. In this paper we try to explain these phenomena with the farms' history prior to the transition period. Particular attention is given to sunk costs, the identity of members and employees, and old debts. A Data Envelopment Analysis of 210 financial statements distributed over the financial years 1992/93 to 1995/96 gives evidence that these historical arguments had a decisive impact on the farms' behaviour. However, this impact decreases over... |

We address the efficiency in education and health sectors for a sample of OECD countries by applying two alternative non-parametric methodologies: FDH and DEA. Those are two areas where public expenditure is of great importance so that findings have strong implications in what concerns public sector efficiency. When estimating the efficiency frontier we focus on measures of quantity inputs. We believe this approach to be advantageous since a country may well be efficient from a technical point of view but appear as inefficient if the inputs it uses are expensive. Efficient outcomes across sectors and analytical methods seem to cluster around a small number of core countries, even if for different reasons: Japan, Korea and Sweden. |

An emerging requirement for the evaluation of the rural development policy is the adoption of an objective method accounting for both material and immaterial achievements, and measuring the performance in order to understand the degree of accomplishment of policy objectives. In this paper we propose a Data Envelopment Analysis (DEA) approach capable of dealing with economic and social indicators, to measure the (relative) technical efficiency of a set of Local Action Groups (LAGs) operating within the LEADER programme. An evaluation exercise referred to eight LAGs located in Italy, is provided to demonstrate the effects of the inclusion of social capital indicator in the evaluation of the LAGs’ performances. In particular, the DEA allows to measure the... |

Propôs-se, neste artigo, uma busca de alvos, por etapas, com alvos intermediários nas camadas de iso-eficiência para que o Setor de Fabricação de Produtos Alimentícios e Bebidas (SFPAB) de cada estado atinja, de forma gradual, um nível de eficiência técnica mais elevado. Utilizaram-se dados da Pesquisa Industrial Anual (PIA) de 2005 do IBGE. Aplicou-se a análise envoltória de dados (DEA) orientada ao insumo, tendo-se a receita líquida do setor como produto e como insumos o total do custo das operações industriais (COI) e as remunerações do setor (SRO). Dos 18 estados analisados, São Paulo é o mais eficiente e Santa Catarina, o mais ineficiente. Outros 11 estados são tecnicamente ineficientes, de forma que 6 devem, no curto prazo, buscar a camada 1; 5 a... |

Maize is the staple food for most Kenyan households, and grown in almost all the farming systems. Due to diminishing farm sizes in Kakamega District, crop productivity and the efficiency of farming systems are of great concern. This paper aims to provide empirical evidence on the links between efficiency in maize production and access to soil-related agricultural information services. Using cluster sampling, a total of 154 farmers in Kakamega District were interviewed. A 2–step estimation technique (Data Envelopment Analysis (DEA) and Tobit model) were used to evaluate the technical efficiencies among the farmers and the factors explaining the estimated efficiency scores. Data was disaggregated into farmers with and those without access to soil-related... |

En este trabajo se realiza un análisis comparado de dos métodos no paramétricos de medida de productividad total de los factores con datos de panel basados en programación: índices de Malmquist y un modelo DEA intertemporal que permite acotar las medidas de eficiencia y progreso técnico, suponiendo cambio técnico no regresivo. La aplicación se realiza sobre las agriculturas de los países de la Unión Europea, encontrándose algunas diferencias importantes entre ambos enfoques. Los resultados sugieren menor crecimiento de productividad agraria y, sobre todo, una ordenación distinta de países en relación con dichos crecimientos que los encontrados en otros trabajos. Palabras clave: Productividad, DEA, Agricultura, Europa, Datos de panel. SUMMARY This paper... |

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... |

Two types of guidelines can be obtained from a DEA (data envelopment analysis) analysis. Firstly, the firm can reduce input or increase production according to the DEA results. Secondly, an inefficient firm might be able to identify reference units. This makes it possible for the inefficient firm to, on site, study production that is more efficient, and thereby get information on e.g. efficient organisational solutions. In this study, we focus on how to detect these firm-relevant reference units. While applying the existing methods for identification of reference units, i.e. the intensity variable method and the dominance method, on a data set concerning booking centres in the Swedish taxi market, shortcomings in these methods were identified. This... |

This study estimates the technical, allocative and economic efficiency obtained from the Data Envelopment Analysis (DEA) approach using farm level survey data to a sample of 100 poultry farmers in Bangladesh for the year 2007. The results from the DEA approach show that there is substantial technical, allocative and economic inefficiency in poultry production in Bangladesh. The results of the study reveal that under constant return to scale (CRS) and variable returns to scale (VRS) specification, on average, the farms technical, allocative and economic efficiencies were 88%, 70%, 62% and 89%, 73%, 66% respectively. Thus the results indicate that efficiency scores vary substantially across the sampled farms. To explain some of these variations, the... |

In this paper we examine more closely the factors associated with production inefficiency in China’s agriculture. The approach we take involves a two-stage process where output efficiency scores are first estimated using data envelope analysis (DEA), and then in the second stage, variation in the resulting efficiency scores are explained using a truncated regression model with inference based on a semi-parametric bootstrap routine. Among the results we find a heavy industrial presence is associated with reduced agricultural production efficiency and may be an indication that externalities from the industrial process, like air and ground water pollution, affect agricultural production. We also find evidence that counties with a large percentage of the rural... |
