Testing Market Integration

Abstract

Abstract A model of spatial price differentials for a tradable good is proposed which avoids the inferential dangers of received methods using static price correlations. The proposed method also extracts more information on the causes of price differentials from the same data. The method is illustrated using monthly rice price data for postindependence Bangladesh, including the very substantial regional price shocks during the 1974 famine. Impediments to market integration are indicated.
