Última A Bayesian Total Factor Productivity Analysis of Tropical Agricultural Systems in Central-Western Africa And South-East Asia AgEcon Tonini, Axel; Matus, Silvia Saravia; Gomez y Paloma, Sergio. This paper computes and analyses total factor productivity (TFP) growth rates for tropical agricultural systems in Central-Western Africa and South-East Asia. Two regions that despite sharing common agro-ecological conditions, have pursued different adoption rates of green revolution technology and have reported dissimilar yields per hectare. A panel data set is constructed for the period 1987-2007 from the FAOSTAT database. A Bayesian stochastic frontier model with country specific temporal variation in technical efficiency is estimated. Technical efficiency estimates reveal that there is substantial room for improvement in both continental sub-sets and that TFP estimates show on average larger rates of growth for South-East Asian countries as compared to...

Ano: 2011 URL: http://purl.umn.edu/116088 Trip-Level Analysis of Efficiency Changes in Oregon's Deepwater Trawl Fishery AgEcon Tomberlin, David; Holloway, Garth J.. In 2003, an industry-financed, government-administered buyback of trawl fishing permits and vessels took place on the US West Coast, resulting in the retirement of about one-third of the limited-entry trawl fleet. The lack of cost data in this fishery precludes an analysis of how the buyback has affected profitability, but changes in technical efficiency can provide some insight into the program's effects. This paper, the first of a planned series of analyses of the buyback's effect on technical efficiency in the trawl fleet, applies stochastic frontier analysis to assess whether technical efficiency changed perceptibly after 2003. We adopt a hierarchical modeling approach estimated with Markov Chain Monte Carlo methods, and present results from both...

Ano: 2007 URL: http://purl.umn.edu/8223 Will Small-Scale Dairy Producers in Kenya Disappear Due to Economies of Scale in Production? AgEcon Omiti, John M.; Wanyoike, F.; Staal, Steven J.; Delgado, Christopher L.; Njoroge, L.. There is growing policy concern regarding the competitiveness of small-scale livestock production in the wake of the contemporary livestock revolution in many developing countries. In Kenya, this debate has focused on economies of scale and the undue influence of policy distortions on promoting the scaling up of dairy farms. This paper seeks to investigate economies of scale in Kenyan dairy in terms of relative profit efficiency at different levels of output, and identify policy and technology options to help small-scale farmers develop solutions to the challenges of competition. Data were collected from 204 dairy producers of different farm sizes in rural Kiambu and Thika, and urban Nairobi districts and a stochastic frontier model approach was used to...
