Coffee Market Liberalisation and the Implications for Producers in Brazil, Guatemala and India*
研究了咖啡市场自由化对巴西、危地马拉和印度生产者的影响，发现自由化提高了生产者获得的世界价格份额和实际价格，质疑了重新管制市场的呼吁。
The standard approach to modelling the relationship between world and producer prices of coffee does not incorporate the effects of changing government policies and market structures. These changes have led to large structural breaks in the relationship between the prices implying the standard estimates are biased. We model coffee prices in Brazil, Guatemala and India allowing for the structural breaks and show that the liberalisation of coffee markets has benefited producers substantially both in terms of a higher share of the world price of coffee and higher real prices. This suggests that calls to re-regulate coffee markets may be misplaced.
