Svensson, Jakob, and David Yanagizawa-Drott. 2009. “Getting Prices Right: The Impact Of The Market Information Service In Uganda”. Journal Of The European Economic Association 7 (2-3): 435-445.
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.
