Technical Efficiency among Peasant Farmers Participating in Natural Resource Management Programmes in Central America
研究了中美洲萨尔瓦多和洪都拉斯山区639个农户的技术效率，发现提高技术效率既能增加农户收入，又有助于环境可持续性，且与产出多样化、非农收入、人力资本和农业推广正相关。
Abstract This study examines the extent to which technical efficiency (TE) is related to activities promoted by two natural resource management programmes recently completed in Central America. Data for a total of 639 farms operating in the hillsides of El Salvador and Honduras are used to estimate a household‐level input‐oriented stochastic distance frontier simultaneously with a TE effects model. The main finding of this study is that improvements in TE are financially beneficial to farm households while also contributing to environmental sustainability. The results also reveal a positive association between productivity and output diversification, and a positive relationship between TE and off‐farm income, human capital and agricultural extension.
