Última Farmer Participation in Supermarket Channels, Production Technology and Technical Efficiency: The Case of Vegetables in Kenya AgEcon Rao, Elizaphan J.O.; Brümmer, Bernhard; Qaim, Matin. Supermarkets are currently gaining ground in the agri-food systems of many developing countries. While recent research has analyzed income effects in the small farm sector, impacts on farming efficiency have hardly been studied. Productivity effects in previous studies are also estimated with respect to different frontiers. Using a survey of Kenyan vegetable growers and a meta-frontier approach, we control for self-selection using propensity score matching and show that participation in supermarket channels increases farm productivity by 35-38%. Effects on technical efficiency are, however, insignificant. Supermarket expansion therefore presents opportunities for realizing agricultural growth, thus enhancing poverty alleviation and rural development.

Ano: 2010 URL: http://purl.umn.edu/61190 Farmer Participation in Supermarket Channels, Production Technology, and Efficiency: The Case of Vegetables in Kenya AgEcon Rao, Elizaphan J.O.; Brümmer, Bernhard; Qaim, Matin. Supermarkets are gaining ground in the agri-food systems of many developing countries. While recent research has analyzed income effects in the small farm sector, impacts on productivity and efficiency have hardly been studied. We use a meta-frontier approach and combine this with propensity score matching to estimate treatment effects among vegetable farmers in Kenya. Participation in supermarket channels increases farm productivity in terms of meta-technology ratios by 45%. We also find positive and significant impacts on technical efficiency and scale efficiency. Supermarket expansion therefore presents opportunities for agricultural growth in the small farm sector, which is crucial for poverty reduction in Africa.

Ano: 2011 URL: http://purl.umn.edu/113508 Measuring productivity differentials – An application to milk production in Nordic countries AgEcon Sipilainen, Timo; Kuosmanen, Timo; Kumbhakar, Subal C.. The aim of this paper is to analyse the regional productivity differentials on dairy farms in Denmark, Finland and Sweden. Several methods have been suggested for analysing productivity differentials in agriculture between groups of farms or countries. Hayami [5] and Hayami and Ruttan [7] suggested the meta-production function approach. This idea has been further developed by Lau and Yotopoulos [9] and Fulginity and Perrin [13]. Battese and Rao [2] suggested the meta-frontier analysis for these comparisons. One of the advantages of meta-frontiers with respect to metaproduction functions is that they are able to separate technological differences from the differences in technical efficiency. Battese et al. [5] and O’Donnell et al. [16] have extended this... Tipo: Conference Paper or Presentation Palavras-chave: Productivity; Technical efficiency; Meta-frontier; Productivity Analysis.
