Hence, a significant lesson from DFS is that productivity improvements under competition get transmitted across country borders—there is no absolute gain by one country and corresponding absolute loss for the other country. In the long-run equilibrium our rate of inflation is zero.

The model assumes the traditional classical framework of two trading countries and of labor being the sole factor of production. The shocks that produce the movements in the nominal exchange rate are associated with changes in the real exchange rate and hence with current account deficits or surpluses.

As Obstfeld and Rogoffstressed, if a monetary shock leads to current account imbalances, the ensuing wealth shifts can have long-lasting real effects far beyond the length of fixity in any nominal contracts.

Aggregate demand is determined by the standard open economy IS-LM mechanism That is to say, the position of the Investment Saving IS curve is determined by the volume of injections into the flow of income and by the competitiveness of Home country output measured by the real exchange rate.
