Transport Costs and Smallholder Cropping Choices: An Application to Siaya District, Kenya
通过将高交易成本纳入农业家庭模型，解释了肯尼亚小农户为何偏好低产粮食作物而非高回报经济作物，并指出改善农村道路可促进专业化、提高收入。
Abstract Smallholders regularly devote shares of resources to low‐yielding food crops than they do to cash crops that have higher market returns. In this paper, costly exchange is incorporated into an agricultural household model, and a numerical nonseparable version of the model is used to show that seemingly inefficient cropping choices of this type in Siaya District, Kenya, can be explained as rational food import substitution given high transport costs in product markets. Improved rural road networks that reduce these costs could abate motives to meet food needs through domestic production and promote specialization that raises farm incomes.
