A CGE analysis of trade costs in the Russian agrofood sector

Ten years after the end of central planning, enormous interregional price differences indicate that Russian food markets are not well integrated spatially. Trade potentials are thus not exploited, most probably because of high trade costs. Besides transport costs, transaction costs seem to play an important role as an impediment to interregional arbitrage. These transaction costs can be very high in transition countries due to underdeveloped market structures and weak public institutions. After subtracting transport costs from interregional price differences, large differences remain, particularly in the case of high-value products. It is assumed that these residual price differences constitute the transaction cost component of total trade costs. The regional economic impact of different trade cost components is quantified using a bi-regional computable general equilibrium (CGE) model. Simulations show that the results are quite different between the two stylized regions (East and West), depending on which trade cost component is reduced. While the welfare effects of varying customs tariffs and transport margins are rather limited, lower transaction costs of trade seem to be a promising way to achieve a better functioning food market in Russia.
