The Evolution of Market Integration in Russia

We use a statistical model of commodity trade to measure the extent of integration between regional commodity markets within Russia. Monthly time-series data on regional commodity prices spanning 1994 through 1999 indicate substantial temporal fluctuations in integration over this period: an initial period of widespread integration gradually gave way to a period of disconnectedness in 1995 through 1997, which seems to have subsided by mid-1998. These temporal fluctuations exhibit strong statistical relationships with a host of aggregate variables; most notably, internal integration exhibits a strong negative relationship with international trade.
