Última Sub-vector Efficiency analysis in Chance Constrained Stochastic DEA: An application to irrigation water use in the Krishna river basin, India AgEcon Chellattan Veettil, Prakashan; Ashok, Arathy; Speelman, Stijn; Buysse, Jeroen; Van Huylenbroeck, Guido. All deviations from the frontier is inefficiency in deterministic DEA (DDEA); thus making the DDEA unable to accommodate the measurement and specification errors. But, most of the production relationships are stochastic in nature with some inputs fixed in the short run. This paper addressed the above two issues by formulating a sub-vector efficiency model in a Stochastic DEA (SDEA) framework to analyze the efficiency of sub vector of inputs. The results illustrate that there is a wide scope for stochastic efficiency analysis. The overall efficiency in SDEA is higher than DDEA under both Constant and Variable Return to Scale frameworks. SDEA revealed that some efficient producers are not sub-vector efficient in our case study. Thus, overall efficiency...

Ano: 2011 URL: http://purl.umn.edu/98978 Spatial Modelling of Water Availability and Choice of Crop Production in a River Basin AgEcon Chellattan Veettil, Prakashan; Van Huylenbroeck, Guido. This paper analyze the problems of water resource allocation and crop choice in a river basin using spatial analytical tools. Spatial variability of water availability is modelled by the product sum model. Here the water availability at any farm Z(xj) is a joint spatio-temporal environment and socioeconomic process. Water availability is estimated using spatial econometric tool. Here the spatial weight matrix (W) is constructed by taking water user associations (WUA) as boundaries. The choice of a crop is explained using spill over model in which the choice of a crop is influenced by the choice of neighbouring farmers. Here the spatial lag model is modified to adapt the latent variable (y*) which has a binary outcome.
