摘要

虽然改良牧草品种具有为牲畜提供优质饲料和优化牲畜营养与生产的潜力,但发展中国家对改良牧草品种的需求却很低。为了给旨在增加改良牧草需求的干预措施(如定价)提供信息,我们评估了肯尼亚梅鲁县农民对不同改良种子和两种干饲料的支付意愿(WTP)。我们采用了多种抽样策略,招募了 356 名奶牛场主参与研究。我们使用贝克尔-德-格罗特-马沙克(BDM)机制来激发WTP,并在分析中使用了混合效应模型。我们发现,饲草产品(除一种外)的 WTP 都低于市场价格,而且加入合作社的奶农与未加入合作社的奶农之间的 WTP 有显著差异。就相关品种而言,没有一个品种的购买意愿明显优于其他品种。我们还发现,以前接触过牧草、农场规模较大、主要实行零放牧以及拥有牲畜的农民更有可能出价高于市场价格。我们的研究结果表明,需要采取能够降低改良牧草价格的策略,如降低与生产、认证、储存和运输相关的成本。对农民进行培训,特别是关于改良性状益处的培训,有可能增加农民为改良性状支付溢价的可能性,这也是改良牧草产品实现规模商业化的重要因素。

Are dairy farmers willing to pay for improved forage varieties? Experimental evidence from Kenya

Though improved forage varieties have the potential to supply high quality feed for livestock and optimize livestock nutrition and production, demand for them in developing countries is low. To inform interventions aiming to increase demand for the improved forages such as pricing, we assessed farmers’ willingness to pay (WTP) for different improved seeds and two types of dried feed in Meru County Kenya. We used a mix of sampling strategies to recruit 356 dairy farmers into the study. We used the Becker-De-Groote Marschak (BDM) mechanism to elicit WTP, and a mixed effects model in the analysis. We find that the WTP for the forage products (except one) was below the market prices, and that the WTP differed significantly between farmers in cooperatives and those that were not. For related varieties, none is significantly superior to other varieties in terms of WTP. We also find that farmers who had prior exposure to the forages, larger farm sizes, mainly practiced zero grazing, and owned the livestock were more likely to bid above the market prices. Our results underscore the need for strategies that can lower the prices of the improved forages such as reducing the costs associated with their production, certification, storage, and transportation. Training farmers especially on the benefits of the improved traits can potentially increase the likelihood of farmers paying premiums for the improved traits, an important ingredient for the commercialization of the improved forage products at scale.

期刊介绍: Food Policy is a multidisciplinary journal publishing original research and novel evidence on issues in the formulation, implementation, and evaluation of policies for the food sector in developing, transition, and advanced economies. Our main focus is on the economic and social aspect of food policy, and we prioritize empirical studies informing international food policy debates. Provided that articles make a clear and explicit contribution to food policy debates of international interest, we consider papers from any of the social sciences. Papers from other disciplines (e.g., law) will be considered only if they provide a key policy contribution, and are written in a style which is accessible to a social science readership.
