Abstract: | In this paper, we adapt the concept of fundamental equilibrium exchange rates ‘FEER’ in a complete model approach. We use it to determine the likely paths of the Dollar and other key currencies. The FEER is the (real) exchange rate that is consistent with internal balance and sustainable external balances. Here we examine the composition of a Dollar adjustment and hence the extent to which a FEER (for the US) depends on factors or rigidities elsewhere in the world, as well as at home. We find, the US still needs to accept an adjustment in her real exchange rate if the increase in her foreign liabilities is to come to an end. However, counterpart adjustments also have to be made in Canada, Mexico, and some Asian economies if this policy is to be successful. We also show that productivity growth differentials may act as a substitute for depreciation, and this provides an explanation for the failure of the dollar to depreciate in the 1990s. |
