Expansionary and contractionary effects of exchange rate shock in developing economies has been the subject of an extensive debate but the results are inconclusive. This study has been conducted to examine the repercussions of unexpected exchange rate depreciation in the Pakistan economy. Unlike the previous literature, this study utilizes a fairly large macroeconometric model constructed on the basis of Cowles Commission structural approach. The study explores that expansionary effect of exchange rate depreciation explained by the traditional theories of open economy macroeconomics persists only for one fiscal year but these theories don’t work in the long-run as contractionary phase starts in the subsequent years. Monetary and fiscal authorities are not neutral and contractionary policy is taken in response to depreciation which pushes the economy into recession. Stagflationary effects are clearly observed. However, improvement in foreign sector prolongs for a number of years and policy makers would have to face a trade-off between opposite response of output and current account balance. Hence, unexpected depreciation generates sharp cyclical fluctuations on demand which immediately transmit to supply side of the economy. In line with the views of “New Structuralists”, exchange rate depreciation may be considered as a source of shock rather than shock absorber in the case of Pakistan economy. Although this study is specifically estimated for the Pakistan economy, authors believe that their methodological contributions and results are of wider importance for policy makers in developing countries.
