Counterfeit and sub-standard antimalarial drugs present a growing threat to public health. This paper investigates the mechanisms that determine the prevalence of fake antimalarial drugs in local markets, their effects, and potential interventions to combat the problem. We collect drug samples from a large set of local markets in Uganda using covert shoppers and employ Raman spectroscopy to test for drug quality. We find that 37 percent of the local outlets sell fake antimalarial drugs. Motivated by a simple model, we conduct a market-level experiment to test whether authentic drugs can drive out fake drugs from the local market. We find evidence of such externalities: the intervention reduced prevalence of substandard and counterfeit drugs in incumbent outlets by half. We also provide suggestive evidence that misconceptions about malaria lead consumers to overestimate antimalarial drug quality, and that opportunistic drug shops exploit these misconceptions by selling substandard and counterfeit drugs. Together, our results indicate that high quality products can drive out low quality ones, but the opposite is true when consumers are less able to infer product quality.

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. Publisher's VersionAbstract

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.
