| 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... |

| A stochastic production frontier model was estimated to provide standard measurement of technical efficiency of the dual-purpose cattle system located in Zulia State, Venezuela. This system is based on local and low-cost inputs, but has been considered to be inefficient because of its low partial productivity indices when compared with those used in developed countries. Results indicate that the efficiency of this system is reasonably high, downplaying the general idea of inefficiency. Likewise, the efficiency of this system has the potential for improvement through public policies and managerial decisions based on the determinants of technical efficiency. |

| The paper investigates the difference in technical efficiency and technology between French and Hungarian farms in dairy and cereal, oilseed and protein seed (COP) sectors during 2001-2004. The analyses is performed with Data Envelopment Analysis (DEA) under separate and common frontiers. Results indicate that Hungarian dairy farmers are more clustered to their own frontier than French farms are, but that the difference is less clear in COP farming. Hungarian dairy and COP farms are less scale efficient than French farms on average. Under a common hypothetical technology, Hungarian farms would be the leaders. Reasons might be the presence of large corporate farms and a higher public support in Hungary. |

| The non-renewal of land leases since 1997 and the impending withdrawal of the European Union's sugar preferences in 2007 have created major uncertainties in Fiji's sugar industry. In the context of this troubled environment, this paper examines the impact of various socio-economic factors on the viability of the industry by focusing on farm efficiency in sugar cane production. It was found that, in general, farmers were inefficient and produced 25% less than their potential output. Among the farm inputs, land (labour) was relatively the most (least) efficiently used input. Empirical evidence also suggests that the more productive Indian farmers rather than the natives be left to farm cane and that large scale farming should be seriously considered by... |

| The economic well-being of most U.S. farm households depends on income from both onfarm and off-farm activities. Consequently, for many farm households, economic decisions (including technology adoption and other production decisions) are likely to be shaped by the allocation of managerial time among such activities. While time allocation decisions are usually not measured directly, we observe the outcomes of such decisions, such as onfarm and off-farm income. This report finds that a farm operator’s off-farm employment and off-farm income vary inversely with the size of the farm. Operators of smaller farm operations improve their economic performance by compensating for the scale disadvantages of their farm business with more off-farm involvement.... |

| In this study, we estimate an output distance function in the context of a multi-output and multi-input production technology by stochastic frontier techniques. Unbalanced panel data for smallholder farms that grown cassava and other crops in Southwestern Nigeria covering 2006/07 to 2008/09 farming seasons is used for the analysis. The results show that the marginal rate of transformation (MRT) between “other crops” grown by the farmers and cassava produced relative to the output mix is negative and significantly different from zero. We observed also that increasing returns-to-scale as well as technical progress characterized cassava production in the region. Furthermore, fertilizer and pesticides are found to have significant substitution effects on... |

| A representative sample of 49 state and collective farms in Ukraine provides data in physical units on livestock and crop production and input use for 1989-92. The changes in production efficiency for beef, pork, dairy, winter wheat, grain, and potato production, investigated using stochastic frontier methods, show declining technical efficiency in livestock production and especially low marginal contribution of labor inputs. The number of workers, size of farm, and distance from nearest city are related to efficiency in agricultural production. |
