| Agribusiness firms are often faced with the challenge of strategically managing employees to achieve a favorable position in the market (i.e. sustained competitive advantage). The resource based view (RBV) has been given considerable attention in the strategic management literature as a useful framework to analyze the significance of human resources in achieving sustained competitive advantage. However, there are few labor management studies in agribusiness that have used the RBV to provide evidence of a substantial relationship between any particular personnel management practice and competitive advantage. This paper provides an in-depth review of the RBV as a potential framework to analyze labor management practices in agribusiness. A case study is used... |

| The paper has several specific objectives. First, it identifies how fertilizer marketing costs and the types of fertilizers used have changed over the course of the liberalization process in Kenya. A second objective is to examine the fertilizer subsector in Kenya with a view to identifying organizational and institutional changes that could improve its performance. Various types of fertilizer supply chains serving farmers in western Kenya are identified, examine the cost structure of these supply chains, identify potential sources of cost reduction in these supply chains, and last, estimate the impact of illustrative scenarios for reducing fertilizer marketing costs on the profitability of maize production in western Kenya. |

| Farming activities are often financed using debt yet empirical studies that investigate the relationship between farm debt structure and performance are still rare. In a ten years unbalanced panel (1995-2005) of Western Australia broadacre farms, we relate the impact of long-term debt, short-term debt and tax liability on farm performance measured by input-oriented technical efficiency and return on assets (ROA). To check for the robustness of our results, both data envelopment analysis (DEA) and stochastic frontier analysis (SFA) methods are employed. Results from both models are consistent: farm production efficiency is positively related to shortterm debt, tax liability and investment and negative related to off-farm income activities. Longterm debt has... |

| The objective of this paper is to analyze sources of labor productivity growth in the Kansas farm sector over the period 1993-2006 for a sample of 668 farms. The nonparametric production frontier method is used to decompose labor productivity growth into three components: (1) technological catch-up, (2) technological change, and (3) capital deepening. Kernel estimation methods are used to analyze the evolution of the entire distribution of labor productivity in the sample period. We find that labor productivity is primarily driven by capital deepening. On average, capital deepening is the main source of convergence in productivity and technical change is a source of divergence. We find little evidence of technological catch-up. The impact of the three... |

| 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. |

| How do dairy farms manage their human resources and how can the farms achieve competitive advantage through the human resource management (HRM) function? This inductive study of six dairy farms in Michigan explores those two questions using the resource-based theory (RBT) framework. Onsite interviews were conducted with 7 managers, 6 herdsmen and 7 non-supervisory employees. An interpretive research paradigm was used for both within case and between case analyses. Drawing insights from the RBT which postulates that valuable, rare, inimitable, and non-substitutable resources confer competitive advantage, results from this study indicate that dairy farms have the potential to achieve competitive advantage through their HRM function. While there are similar... |

| 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... |

| The State government of Western Australia is currently working through a significant program of local government reform that has as a core objective a reduction in the number of local councils. The perception that there are economies of scale in service delivery is a key reason behind the State government’s desire to see a reduction in the number of councils in Western Australia. The following article uses the technique of Data Envelopment Analysis to measure the technical and scale efficiency of councils in Western Australia. The average pure technical efficiency score for Western Australian councils was found to be 83 per cent, and the average scale efficiency score was found to be 94 per cent. This suggests that pure scale effects are not a major... |

| In this article, we used bootstrap data envelopment analysis techniques to examine technical and scale efficiency scores for a balanced panel of 564 farms in Kansas for the period 1993–2007. The production technology is estimated under three different assumptions of returns to scale and the results are compared. Technical and scale efficiency is disaggregated by farm size and specialization. Our results suggest that farms are both scale and technically inefficient. On average, technical efficiency has deteriorated over the sample period. Technical efficiency varies directly by farm size and the differences are significant. Differences across farm specializations are not significant. |

| Recent empirical studies on agricultural productivity growth in African countries have produced mixed results; some find that uptake of new technology (technical progress) is the main source of total factor productivity growth while others point to improved use of existing technology (efficiency catch-up). This study tests for efficiency catch-up in the agricultural productivity of 33 African countries from 1966 to 2001. We use recent advances in data envelopment analysis (DEA) to generate standard and bootstrap bias corrected technical efficiency scores. In general, we find no evidence of efficiency catching-up. The standard DEA overestimated the efficiency scores of some countries due to small sample bias. |
