Measuring Spatial Integration in Niger Grain Markets

Seydou Zakari, Liu Ying


This paper investigates the spatial integration of Niger cereal markets using monthly retail prices of four staple crops consumed daily in the country. We used co-integration techniques to analyze the price relationship between six main markets. The results revealed high co-integration in Millet and Maize market pairs. On the Contrary, the study indicates also high absence of co-integration in most of Rice and Sorghum markets. Many factors such as poor infrastructures, government interventions, may be major impediments to spatial integration between markets. Development of private grain marketing will help to improve trading between markets, thereby increasing competition and circulation of grain from surplus areas to supply deficit areas.
