| 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... |

| Brazil now is the largest coffee, sugar, and fruit juice producer, second-largest soybean and beef producer, and third-largest corn and broiler producer. It has overtaken the U.S. in poultry exports, nearly matches the U.S. in soybean exports, and dominates global trade in frozen orange juice. To test and better understand these advances, we draw on decennial farm censuses to examine technical change and efficiency in Brazilian agriculture. Our approach is to estimate a stochastic, multi-product, output distance frontier, using a translog functional form and data disaggregated to the micro-region (sub-state) level. Using two consecutive decennial farm censuses, we combine state-level Fisher productivity-change indexes with state-level translog distance... |

| Sustaining and improving production efficiency of resource poor smallholder farmers under the existing credit constraint conditions require the improvement of access to credit facilities and other factors involved. The study examined the factors influencing credit constraint (CC) and production efficiency of farming households in Oyo State, Nigeria. Primary data was randomly collected using structured questionnaire from 120 mixed farmers in the study area. Data was analyzed using descriptive analysis, probit regression and stochastic frontier analysis. The results shows that 79.2 percent of the respondents were credit constrained and this has negative influence on their production efficiency as credit constrained farming households (CCFH) were found to be... |

| The production performance of wheatbelt farms in Western Australia is analysed to determine whether potential to exploit scale economies and improve technical efficiency has driven the trend towards increased farm size. An input-orientated stochastic frontier model is used to estimate technical efficiency and scale economies using an unbalanced panel dataset provided by BankWest for the period 1995/1996 to 2005/2006. Differences in the relative efficiency of farms are explored by the simultaneous estimation of a model of inefficiency effects. The results show the majority of wheatbelt farms operate at high levels of technical efficiency and experience increasing returns to scale. Over the study period farms became bigger to benefit from economies of scale,... |

| This paper estimates a stochastic production using household survey data to analyze the relationship between farmers’ health impediments and agricultural production efficiency in Ethiopia. The results show that healthy farmers produce more per unit of inputs, earn more income and supply more labor than farmers affected by sickness. The model results show that production inefficiency increases significantly with the number of days lost to sickness. This finding suggests that investing in the health sector in rural areas will not only improve farmers’ agricultural performance but also increase their income. Policymakers should therefore devise strategies that will maximize the contribution of health investments to agricultural productivity and the overall... |

| This study investigates a number of factors influencing technical efficiency of Greek farms participating in the 1994 European Union (EU) farm credit program. Technical efficiency measures are obtained within the framework of a parametric stochastic frontier. Factors showing a positive effect on technical efficiency are value of liabilities, number of hours of mechanical operation, large land size, and rental land, whereas those showing a negative effect are value of EU product subsidies, value of off-farm family income, and hired labor. The value of investments incurred by farms because of their participation in the 1994 farm credit program does not show any significant effect on technical efficiency. The predicted levels of technical efficiency... |
