Interlinked credit and farm intensification: evidence from Kenya
利用肯尼亚面板数据，研究发现参与特定经济作物关联营销项目的农户，在其他粮食作物上施用更多化肥，表明这种制度安排对粮食生产有溢出效益。
This paper addresses the potential for interlinked credit/input/output marketing arrangements for particular cash crops to promote food crop intensification.Using panel survey data from Kenya, we estimate a household fixed-effects model of fertilizer use per hectare of food crops.Results indicate that households engaging in interlinked marketing programs for selected cash crops applied considerably greater fertilizer on other crops (primarily cereals) not directly purchased by the cash crop trading firm.These findings suggest that, in addition to the direct stimulus that interlinked cash crop marketing arrangements can have on small farmer incomes, these institutional arrangements may provide spillover benefits for the productivity of the farmers' other activities such as food cropping.
