Agricultural input credit in Sub-Saharan Africa: Telling myth from facts
基于四个非洲国家的全国代表性数据，研究发现农民购买化肥等现代投入品时，传统信贷（正式或非正式）使用率极低，主要依靠非农收入和作物销售现金，而捆绑式产出-劳动安排是唯一相对广泛使用的信贷形式。
Recent evidence shows that many Sub-Saharan African farmers use modern inputs, but there is limited information on how these inputs are financed. We use recent nationally representative data from four countries to explore input financing and the role of credit therein. A number of our results contradict "conventional wisdom" found in the literature. Our results consistently show that traditional credit use, formal or informal, is extremely low (across credit type, country, crop and farm size categories). Instead, farmers primarily finance modern input purchases with cash from nonfarm activities and crop sales. Tied output-labor arrangements (which have received little empirical treatment in the literature) appear to be the only form of credit relatively widely used for farming.
