The Effects of the Coffee Trademarking Initiative and Starbucks Publicity on Export Prices of Ethiopian Coffee†

摘要

The Ethiopian government initiated the Ethiopian Coffee Trademarking and Licensing Initiative in 2004 for three coffee origins: Sidama, Yirgacheffe and Harar. Following a court case between Starbucks and the Ethiopian government regarding the trademarking of ‘Sidamo’, Ethiopian government engaged in a public relations campaign to raise awareness for the Initiative, which was widely publicised in the international media especially after Oxfam organised a public campaign. This paper evaluates the effect of these interventions on the export prices of trademarked Ethiopian coffees. We find that the prices of the trademarked coffees increased by about 10% relative to the non-trademarked coffees following these interventions. The magnitude of this change is comparable with the farm gate prices reported in the literature; however, we cannot establish direct causation or observe the passthrough into farm gate prices.
