Russia’s common market takes shape: Price convergence and market integration among Russian regions

Abstract

This paper analyzes the spatial structure of goods market integration in Russia, characterizing regions into three states: (a) integrated, (b) not integrated but trending toward integration, and (c) not integrated and not trending toward integration. Using time series of the cost of a staples basket across 75 regions of Russia for 1994-2000, I exploit a nonlinear cointegration relationship with an asymptotically subsiding trend to capture movement toward integration. The analysis suggests that 36% of Russian regions were integrated with the national market over 1994-2000, 44% were in the process of integrating with the national market, and 20% of regions were not integrated and not trending toward integration.market integration; law of one price; price dispersion; convergence; Russian regions
