Devaluation, Fiscal Deficits, and the Real Exchange Rate

This article examines the use of fiscal policies to sustainthe effects of a nominal devaluation on the real exchange rate.It is shown that the magnitude of the change in the real exchangerate depends not only on the size of the devaluation and thedegree of fiscal adjustment but also on the means by which thefiscal deficit is reduced. The change in the nominal exchangerate necessary to maintain the depreciation of the real exchangerate will depend on whether the fiscal deficit is eliminatedby increasing taxes or by reducing government expenditures ontraded and nontraded goods. The required depreciation of thedomestic currency will be larger if the fiscal deficit is reducedby increasing taxes than it will be if the deficit is cut bylowering government expenditures. Further, the depreciationwould be smaller if the cuts in expenditure fell on traded ratherthan nontraded goods. This result implies that the authoritiesmust ensure consistency between exchange rate action and policiesto reduce fiscal imbalances in order to achieve a desired levelof the real exchange rate necessary to attain balance of paymentsequilibrium.
