Abstract

The impacts of market reforms on prices volatility in developing countries are not well understood because analysts have not been able to predict the impacts. This study investigates whether the reforms have exacerbated the degree of spatial volatility of maize price in Tanzania using ARCH-M model. Results indicate that developed regions might have experienced less volatile prices than less developed regions. Infrastructure development to increase the volume of trade between the regions is recommended.
