Cointegration Tests of Spatial and Variety Price Linkages in Regional Dry Bean Markets
Journal of Agricultural & Applied Economics
Two sets of cointegration tests were performed on regional dry bean prices. The results show (1) prices for the same variety were cointegrated across geographically separated production areas, and (2) prices for different varieties grown in the same production area were not cointegrated. Processors respond to the same export demand signals.
