Developing Agricultural Markets in Sub-Saharan Africa: Organic Cocoa in Rural Uganda
研究乌干达农村有机可可合同种植计划对参与者收入的影响，发现该计划通过建立可信激励促使农民采用提升可可质量的技术，带来显著收益，并可能产生市场深化和生产率提高的溢出效应。
Abstract This article investigates the process of development in a traditional African export market, focusing on a contract farming scheme for organic cocoa in rural Uganda. Based on a repeated household survey, we measure the impact of the scheme on the income of participants and the economic mechanisms behind these effects. We find substantial benefits from the scheme, driven primarily by the establishment of credible incentives for farmers to adopt technologies which improve cocoa quality. There is also evidence of broader trends of market deepening and increased productivity, probably due to positive spillovers.
