Abstract

This article examines the price transmission between two consumer markets (Niamey and Agadez) and four assembly markets Maradi, Zinder, Tillaberi, Dosso) millet in Niger. The cointegration model M-TAR threshold type of Enders and Siklos (2001) was used on monthly series of prices between January 2005 and December 2013. The results highlight the leading role played by the consolidation of markets price controls. The market prices of Maradi, Niamey, Zinder tend to adapt more quickly to higher rather than lower; resulting in a loss of consumer welfare. Asymmetric responses markets millet in Niger lead us to conclude that traders have market power, and the bad roads increase transportation costs.
