摘要

卢旺达的“作物集约化计划(CIP)”主要是一项旨在提高农业生产力和粮食安全的土地整理计划。该项目始于2007年,重点关注玉米、小麦、水稻、白马铃薯、豆类和木薯等六种重点作物的单作和商业化。CIP使人们更容易获得改良的种子库存、肥料、推广服务以及采后处理和储存服务。虽然研究已经记录了CIP对农业产量、收入和生产力变化的影响,但对其对食品价格的影响知之甚少。在本研究中,我们研究了卢旺达集约化单作CIP区和非集约化单作CIP区作物-粮食价格差异。具体而言,该研究评估了在实施CIP政策前后集约化和非集约化单作区豆类和玉米以及辅助性粮食作物的价格变化。我们发现CIP政策与集约化和非集约化单作区之间CIP作物价格的差异无关。随着时间的推移,CIP作物的价格上涨,但总的来说,两个区域的作物价格是协整的。在实施CIP之前,两个不同区域的非CIP作物价格确实存在价格差异,集约化单作区的价格高于非集约化单作区的价格。此外,集约地区的玉米和豆类价格与非集约地区的价格是协整的,而且这些价格正在趋同。这表明集约化生产一种CIP作物的农民能够去市场购买其他粮食作物,区域之间的价格差异随着时间的推移而减少,可能使集约化CIP的农民变得更好。

Land Policy and Food Prices: Evidence from a Land Consolidation Program in Rwanda
Abstract Rwanda’s “Crop Intensification Program (CIP)” is primarily a land consolidation program aimed at improving agricultural productivity and food security. The program, which began in 2007, focuses on monocropping and commercialization of six priority crops: maize, wheat, rice, white potato, beans, and cassava. CIP has facilitated easy access to improved seed stocks, fertilizer, extension services, and postharvest handling and storage services. Although studies have documented the impact of CIP on changes in farm yield, incomes, and productivity, less is known about its impact on food prices. In this study, we examine the crop-food price differences in intensive monocropped CIP and non-intensive monocropped CIP zones in Rwanda. Specifically, the study evaluates price variations of beans and maize along with complementary food crops in intensive and non-intensive monocropped zones before and after the introduction of the CIP policy. We find that the CIP policy is not associated with differences in CIP crop prices between the intensive and non-intensive monocropped zones. Over time, prices increased for CIP crops but generally, the crop prices in the two zones were cointegrated. Prices for non-CIP crops in the two different zones did show price differentials prior to the implementation of CIP, with the prices in intensive monocropped zones being greater than in the non-intensive monocropped zones. Moreover, the prices in intensive areas are cointegrated with prices in non-intensive areas for maize and beans and these prices are converging. This indicates that farmers who intensively produced one CIP crop were able to go to the market and purchase other food crops and that price differences between zones have decreased over time, potentially making the CIP intensive farmers better off.

期刊介绍: The Journal of Agricultural & Food Industrial Organization (JAFIO) is a unique forum for empirical and theoretical research in industrial organization with a special focus on agricultural and food industries worldwide. As concentration, industrialization, and globalization continue to reshape horizontal and vertical relationships within the food supply chain, agricultural economists are revising both their views of traditional markets as well as their tools of analysis. At the core of this revision are strategic interactions between principals and agents, strategic interdependence between rival firms, and strategic trade policy between competing nations, all in a setting plagued by incomplete and/or imperfect information structures. Add to that biotechnology, electronic commerce, as well as the shift in focus from raw agricultural commodities to branded products, and the conclusion is that a "new" agricultural economics is needed for an increasingly complex "new" agriculture.
