摘要

We implement a platform to crowdsource information about service provision quality and prices charged and reveal this information to consumers in a market - artificial insemination of livestock in Punjab, Pakistan - where individual signals of quality are noisy. We measure the impact of this information revelation using a randomized controlled trial. Farmers receiving information enjoy 25% higher insemination success and no higher prices than controls. These effects are due to existing veterinarians increasing effort, rather than farmers switching to possibly higher-quality providers. These results illustrate the viability of information clearinghouses successfully aggregating information in low-capacity markets. They also suggest the importance of doing so by implying large welfare benefits from our low-cost information intervention.
