Great Appreciations: Accounting for the Real Exchange Rate in Mexico, 1988-2002

Between 1988 and 2002, the real exchange rate in Mexico appreciated by 45%. We account for this movement in relative prices using a two sector, dynamic general equilibrium model of a small open economy with tradable an non-tradable goods. The model allows us to identify the effect of the differential in productivity growth across sectors (the Balassa-Samuelson effect) from other types of shocks affecting the allocation of resources (terms of trade, migration remittances and international reserves accumulation). We find that productivity growth in the tradable sector and a decline in the real interest rate faced by Mexico in the international markets account for 70% of the real exchange rate appreciation. Our model is also consistent with the reallocation of capital and labor from tradable to non-tradable sectors. None of our results support a significant role for terms of trade, migration remittances or international reserves accumulation.
