Input management ability, occupational patterns, and farm productivity in Bangladesh agriculture
将农民难以衡量的投入管理能力纳入生产框架，分析其对农场生产率的影响，发现推广项目需加强传统与现代投入的有效使用指导，并应更多面向传统农民。
Abstract Agricultural production involves the use of certain difficult‐to‐measure resource endowments of farmers in addition to observable physical inputs. This article proposes integrating a behavioural component ‐ input management ability ‐ into a production framework that can then be used to analyse the impact of farmers’ supervisory skills and efforts on farm productivity. The empirical analysis suggests that extension programmes may need to be broadened to teach more effective use of traditional as well as modern inputs and that extension services and delivery of modern inputs need to be directed more at traditional farmers than at those in touch with the modern sector.
