Policy reforms and asymmetric price transmission in the Zambian and Tanzanian coffee markets
Several governments in sub-Saharan Africa have embarked on various market reforms to improve commodity market performance. However, the success of such market reforms depends partly on the strength of the transmission of price signals between spatially separated markets and between different levels of commodity value chains. This study employs momentum threshold cointegration and error correction models to examine the impact of policy reforms on the transmission of prices between the world coffee market and domestic prices in Zambia and Tanzania. The findings show that in the case of Zambia, where policy reforms liberalized coffee markets, the producer prices respond more swiftly to decreases than increases in world market prices, and this swiftness increased after the policy reforms. For Tanzania, where reforms resulted in increased government intervention, producer prices were found to respond quicker to increases than decreases in world market prices over the period under consideration. However, the period before reforms showed domestic prices responding more swiftly to decreases than increases in world prices, while the post-reform period was characterized by faster responses to increases than decreases in world prices.
