| This study examined whether the efficiency measures were invariant to choice of parametric and nonparametric methods for a sample of 183 wheat farms. The efficiency measures from the deterministic parametric method were smaller than those from the deterministic method. There was a trade-off between scale efficiency and economic efficiency. In the deterministic nonparametric method, the economic efficiency, scale efficiency and overall efficiency results were invariant to the number of inputs or the dimensionality. Only allocative and pure technical efficiency measures depended on the dimensionality. This work illustrated the importance of holding curvature for the cost function in stochastic frontier results. |

| Household characteristics are commonly used to explain variation in smallholder efficiency levels. The underlying assumption is that differences in intended behavior are well described by such variables, while there is no a priori reason that this is the case. Moreover, heterogeneity in farmer goals and preferences, in relation to the role of the farm enterprise, are not well documented in developing countries. This paper makes a contribution to fill this gap, by empirically determining heterogeneity in farmer goals and attitudes in Nigeria through a pair-wise ranking, supplemented with Likert scales. Factor analysis is used to reduce these data into behavioral factors. We estimate technical and allocative efficiency levels and analyze how these are... |

| This study contributes to the debate regarding the competitiveness of developing countries in the context of globalization. To take advantage of this trend, developing countries will have to position themselves properly through new policies and efficiency in production. In Benin, new orientation of agricultural policy concerns the diversification of exported products. Therefore, and due to the decrease of international price of cotton which represents the main exported crop, cashew nut, the second exported crop by Benin, becomes more interesting for government policy. The study quantified cashew nut production farmers’ efficiency using a stochastic production frontier and a cost function combined with numerical classification. Primary data were collected... |
