The economic impact of bean disease resistance research in Honduras
基于2001年洪都拉斯两大豆产区的农户调查，发现41-46%的农户采用了抗病豆种，采用与农场规模和市场化程度无关；采用者因避免产量损失而获得相当于豆类收入7-16%的收益，1984-2010年抗病研究的回报率为41.2%。
This paper presents evidence of recent adoption rates of disease resistant bean varieties (RVs), the farm-level benefits of RV adoption, and the ex post rate of return to disease resistant bean research in Honduras. Results from a farm-level survey in 2001 in the two principal bean-producing regions of the country show that 41-46% of bean farmers (depending upon the season) have adopted an RV, and that adoption is neutral with respect to farm-size and market orientation. An expected utility framework was used to estimate the farm-level benefits of RV adoption, using a combination of experimental trial and farm-level survey data. Adopters gain the equivalent of 7-16% (depending on the variety) in bean income from the yield loss averted through RV use. The ex post rate of return to disease resistant bean research in Honduras from 1984 to 2010 is 41.2%. © 2003 Elsevier B.V. All rights reserved.
