改善"最后一公里"公共服务递送是发展中国家反复出现的难题。手机的广泛普及能否为改善服务提供一种可规模化、成本效益高的手段?我们利用一项大规模实验,评估基于手机的监测对某个向570万印度农民转移支付了近10亿美元的项目的影响。在随机选定的辖区内,官员被告知项目执行情况将通过与受益人的电话通话加以衡量。这使未收到转移支付的农民人数减少了7.8%。该项目成本效益很高,每多递送1美元仅花费3.6美分。
Abstract
Improving “ last-mile” public service delivery is a recurring challenge in developing countries. Could the widespread adoption of mobile phones provide a scalable, cost-effective means for improvement? We use a large-scale experiment to evaluate the impact of phone-based monitoring on a program that transferred nearly a billion dollars to 5.7 million Indian farmers. In randomly selected jurisdictions, officials were informed that program implementation would be measured via calls with beneficiaries. This led to a 7.8 percent reduction in the number of farmers who did not receive their transfers. The program was highly cost-effective, costing 3.6 cents for each additional dollar delivered.
