Grain transport and rural credit in Mozambique: solving the space–time problem
研究发现信贷市场失灵通过诱导高信贷成本地区增加运输来储存谷物，导致福利损失，且主要影响农村家庭，建议优先改善农村信贷和储存效率。
Abstract This paper shows how credit market failures can lead to large welfare losses in grain markets by inducing increased transport for seasonal storage in locations with low credit costs. The burden of these welfare losses falls primarily on rural households. These conclusions are obtained from a spatial/temporal model solved using a mixed complementarity formulation that easily handles interest rate differentials across space. Efforts to address credit market failures and to improve the efficiency of rural storage should be given priority as opposed to the creation of large, formal sector grain collection centers.
