Dornbusch model

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 Dornbusch model. Imagining a monetary expansion, amounts to shift the saddle-path outwards -and obtain overshooting related to depreciation.

It is a framework for thinking about international monetary policy, not simply a model for understanding exchange rates. Inflation and Indexation, Institute for International Economics, Employment and Inflation, Academic Press, FischerMIT Press, The general reaction of policy economists at the time was that these alternative models, while elegant, were far less relevant empirically than Dornbusch's variant.
