| This article investigates the production efficiency of rice farming in Sri Lanka using cross section survey data of 90 farms. Past studies on rice farming have mostly focused on technical efficiency (TE). Here, we examine technical efficiency, allocative efficiency (AE) and cost efficiency (CE) using the data envelopment analysis (DEA) approach. On average, the farms were 87% technically efficient; irrigated farms were more efficient (88%) than rain-fed farms (82%). Average cost, allocative and scale efficiencies were 73%, 84% and 87%. Bias corrected TE estimate suggests an expected output expansion of 25% with a given input combination in order to become fully efficient as opposed to 16% based on the original estimates. In addition, a second stage Tobit... |

| This paper considers the stochastic production frontier approach to analyse the technical efficiency and its determinants of fish farms in Ghana using a cross-section data of 150 farms. It considers the explicit effects of family and hired labour on production by setting the log-value of the zero-observation of these two sources of labour to zero with dummy variables. Results demonstrate that expected elasticities of mean output with respect to all input variables are positive and significant. Findings also show that family and hired labour used for fish farming in Ghana may be equally productive. Fish farms in Ghana are revealed to be characterised by technology with increasing return to scale. The combined effects of operational and farm specific factors... |

| This paper develops a meta-regression analysis to explain the variation of mean technical efficiency (PETP) measurements from a total of 65 frontier studies that report technical efficiency (ET) measurements at the dairy farm level in the literature published in English and Spanish. The analysis includes the effect of methodology on ET measurements, as well as the effect of the econometric procedure on the meta-regression estimates. Eight models were estimated, and two of these were selected: a fixed effects specification with dummy variables for the most significant studies without geographical effects (EFS), and a specification where the multiple observations are averaged and geographical effects included (OP). Based on model performance, the EFS option... |

| The technical efficiency indexes for the rural producer from the central region of Santa Catarina’s western side have been identified, thus enabling to determine their managerial profile through the evaluation of processes of decision-making in the properties, administration of agricultural business firms, strategical behaviour, time management, and information transferences. Moreover, the inter-relation among efficient enterprises and managerial ability, and vice-versa, was also verified. The methodology used in the qualitative analysis was the Data Envelopment Analysis-DEA, and the data used for such analysis were gathered by means of a semi-structured questionnaire. Twelve out of the fifty-eight analyzed properties did reach the efficiency frontier,... |

| Crop production is the main source of livelihood for households in Northern Ghana. The government is committed to improving crop production and knowledge about the technical efficiency of crop farms is essential in guiding policy decisions. This paper examined the technical efficiency of 189 crop farms in Northern Ghana using data envelopment analysis (DEA) with bootstrapping. We found that bias-corrected average technical efficiency of the sample farms is 77.26%. The estimated scale efficiency is 94.21%. In a second stage regression, we found that hired labour, geographical location of farms, gender and age of head of household significantly affect technical efficiency. Policy implications of the results are discussed. |

| Due to good climate condition and large cultivation area in Mazandaran province of Iran, orchard commodities products, especially orange production is widely improved in this region. In this study, Data Envelopment Analysis (DEA) technique was used to analyze the efficiency of farmers, discriminate efficient orchards from inefficient ones and to identify wasteful uses of energy for orange producers in Sari region. Data were collected using face-to-face surveys from 86 orange orchardists and included the human power, machinery, diesel fuel, chemicals, fertilizer, farmyard manure, water for irrigation and electricity input sources used per hectare of orange production. The data was organized and analyzed by DEA Techniques. The results revealed that 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... |
