Abstract

This paper presents a long-run model of the open economy in a world of fixed exchange rates and imperfect substitutability between bonds denominated in different currencies. The model explicitly accounts for the wealth flow accompanying current-account imbalance and for the flow of interest payments associated with international lending. Both the dynamic and steady-state implications of the model are quite different from those of models that specify the capital account as a continuing flow responding to the level of interest rates. In particular, we find that when there exists outside government debt, open-market policy is not in general neutral in the long run. We also find conditions under which the central bank is able to hold the domestic price level constant in the face of an inflationary disturbance from abroad without exhausting, in the long run, its stock of domestic assets.
