Getting Prices Right: The Impact of the Market Information Service in Uganda
研究乌干达市场信息服务项目，通过电台广播价格信息，发现能接触到信息的农民为剩余产品争取到了更高的收购价。
The Market Information Service project in Uganda collected data on prices for the main agricultural commodities in major market centers and disseminated the information through local FM radio stations in various districts. Exploiting the variation across space between households with and without access to a radio, we find evidence suggesting that better-informed farmers managed to bargain for higher farm-gate prices on their surplus production.
