摘要

许多发展中国家的小农农业的特点是生产率低、产出质量低。低质量限制了农民可以控制的价格和他们的潜在收入。我们在乌干达种植玉米的农民中进行了一系列实验，以揭示质量升级的障碍并研究其潜力。我们发现质量的因果回归为零。提供进入市场的机会，以市场溢价支付质量，从而提高了农业生产力和农业收入。我们的研究结果揭示了需求侧约束在限制农村收入和生产率增长方面的重要性。(jel c93, l14, l15, l22, o13, q12, q13)

Market Access and Quality Upgrading: Evidence from Four Field Experiments

Smallholder farming in many developing countries is characterized by low productivity and low-quality output. Low quality limits the price farmers can command and their potential income. We conduct a series of experiments among maize farmers in Uganda to shed light on the barriers to quality upgrading and to study its potential. We find that the causal return to quality is zero. Providing access to a market where quality is paid a market premium led to an increase in farm productivity and income from farming. Our findings reveal the importance of demand-side constraints in limiting rural income and productivity growth. (JEL C93, L14, L15, L22, O13, Q12, Q13)
