土地租赁市场:来自肯尼亚的实验证据

Land Rental Markets: Experimental Evidence from Kenya

中文摘要

土地市场摩擦是否会导致农业中的资源错配?在肯尼亚西部开展的一项田野实验中,我们随机向土地所有者提供补贴,鼓励其出租土地。补贴诱导的租赁大多在补贴结束后仍然持续,并提高了产出和增加值,这与资源错配的假说一致。交易收益源于承租人选择价值更高的作物、具有更高的生产率并采用更多非劳动投入,而承租人与土地所有者使用的劳动数量相近。补贴诱导的租赁并非预测收益最大的那些,这凸显了收益与摩擦的联合分布的重要性,其中摩擦源于搜寻、风险和学习。(JEL C93、O13、O18、Q12、Q15、Q24、R52)

Abstract

Do land market frictions cause misallocation in agriculture? In a field experiment in western Kenya, we randomly subsidize owners to rent out land. Induced rentals mostly persist after the subsidy ends and increase output and value added, consistent with misallocation. Gains from trade arise from renters choosing higher-value crops, having higher productivity, and adopting more nonlabor inputs, while renters use similar quantities of labor as owners. Induced rentals are not those with the largest predicted gains, underlining the importance of the joint distribution of gains and frictions, with frictions arising from search, risk, and learning.(JEL C93, O13, O18, Q12, Q15, Q24, R52)
