摘要

这篇论文解决了以前没有回答的问题,即私营部门是否可能通过应用先进的生物技术在开发类似的菌株方面发挥未来的作用,以及它们的研究和开发工作是否会使易发生灾害的生态系统中贫穷和脆弱的农民受益。我们采用离散选择实验来检验农民对DT性状的偏好,并利用在印度比哈尔邦农村收集的原始数据探索这些偏好的异质性。使用不同的建模方法来捕获偏好异质性,我们的研究结果表明,农民重视DT品种提供的产量变异性的减少,但即使在正常条件下,他们也愿意为提供产量优势的水稻种子支付更多的钱。

Farmer Preferences for Drought Tolerance in Hybrid versus Inbred Rice: Evidence from Bihar, India
This paper addresses the previously unanswered question of whether the private sector might play a future role in developing similar strains through applications of advanced biotechnology, and whether their research and development efforts would benefit poor and vulnerable farmers in hazard-prone ecosystems. We employ discrete choice experiments to examine farmers’ preferences for DT traits and explore heterogeneity in these preferences using primary data collected in rural Bihar, India. Using different modeling approaches to capture preference heterogeneity, our results show that farmers value the reduction in yield variability offered by DT cultivars but are willing to pay even more for rice seed that offers yield advantages even under normal conditions.
