Última PERFORMANCES AND EFFICIENCIES OF THE IRRIGATION WATER USERS’ ASSOCIATIONS IN TUNISIA AgEcon Frija, Aymen; Speelman, Stijn; Chebil, Ali; Buysse, Jeroen; Van Huylenbroeck, Guido. This article analyzes the efficiency of Water Users Associations (WUA) in the Cap Bon region (Tunisia) and studies its main determinants. The analysis is performed in two stages. First, the efficiency is measured via the nonparametric “Data Envelopment Analysis” (DEA) technique. The DEA models are constructed not only to assess the overall WUA efficiency but also to evaluate the management and engineering sub-vectors efficiencies separately through a mathematical modification in the initial DEA model. In a second stage critical determinants of efficiency are determined using a Tobit model. In this analysis the focus is on technical (characteristics of the irrigation area and network), organizational and administrative variables. Results show that on...

Ano: 2008 URL: http://purl.umn.edu/6460 Efficiency and Productivity in the Spanish Food Distribution Sector AgEcon Palomares, Rafaela Dios. This study investigated the efficiency and productivity change of a sample of food distribution units (MERCAs) in Spain over the 1.997-1.999 period, applying non-parametric frontier methodology in a sales efficiency framework. We specified a mean sales model composed of two blocks of variables, the production block, and the marketing management block. Then we applied output oriented DEA methodology to perform the efficiency analysis, also taking into account the overall efficiency decomposition into pure and scale efficiency. The Malmquist index was calculated in order to analyse the components of the productivity change. The mean pure sales efficiency index was high, around 0.8, the mean scale index being 0,9. As appears from the results, six food... Tipo: Conference Paper or Presentation Palavras-chave: Efficiency; Productivity; DEA method; Malmquist index; Food Distribution Unit; Productivity Analysis.
