Grain transport and rural credit in Mozambique: solving the space–time problem
研究信贷市场失灵如何导致谷物市场福利损失，通过增加运输将季节性储存转移到信贷成本低的地区，农村家庭承担主要损失，建议优先改善农村储存效率而非建立大型谷物收集中心。
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. © 2001 Elsevier Science B.V.
