From Futures Markets to the Farm Gate: A Study of Price Formation along Tanzania’s Coffee Commodity Chain
研究了坦桑尼亚咖啡价格链中价格形成与传导的机制，揭示了国际咖啡贸易商行为与全球资本积累对价格波动的影响，以及地方市场与制度如何缓冲价格冲击并加剧生产者分化。
This article examines the nature of price formation and transmission in the Tanzanian coffee price chain. To date, research on the real-world processes of price formation has been scant in economic geography and extant literatures. This article addresses this by focusing on price formation in geographically distant but connected markets, and the interaction between global and local price dynamics. The article employs a new framework that builds on chain and network approaches by integrating concepts from marketization and institutional approaches. The study finds that the world price of coffee has become increasingly volatile as a result of the behavior of international coffee traders and broader shifts in the character of global capital accumulation. It also demonstrates the varying role domestic marketing and local-level institutions play in shaping price formation and cushioning Tanzanian producers from sudden price changes. Finally, the study highlights the role prices, via these local-level institutions, play in extenuating differentiation between producers, creating winners and losers.
