这项研究估计的好处，印度农民从市场和天气信息提供给他们的移动的手机的商业服务称为路透社市场之光（RML）。我们在马哈拉施特拉邦的100个村庄进行了随机对照实验。接受治疗的农民将RML信息与他们做出的一些决定联系起来，我们发现一些证据表明，治疗影响了空间套利和作物分级。但这些影响的幅度很小。我们发现，处理对农民收到的价格、作物附加值、暴雨造成的作物损失或改变作物品种和耕作方式的可能性没有统计上显著的平均影响。虽然这些结果令人失望，但与研究地区的RML服务市场使用率一致，这表明在研究期间，客户总数很少，使用率相对停滞。
This study estimates the benefits that Indian farmers derive from market and weather information delivered to their mobile phones by a commercial service called Reuters Market Light (RML). We conduct a controlled randomized experiment in 100 villages of Maharashtra. Treated farmers associate RML information with a number of decisions they have made, and we find some evidence that treatment affected spatial arbitrage and crop grading. But the magnitude of these effects is small. We find no statistically significant average effect of treatment on the price received by farmers, crop value-added, crop losses resulting from rainstorms, or the likelihood of changing crop varieties and cultivation practices. Although disappointing, these results are in line with the market take-up rate of the RML service in the study districts, which shows small numbers of clients in aggregate and a relative stagnation in take-up over the study period.
