This paper examines the effects of a fall in world interest rates on c
apital flows and the real exchange rate in an optimizing framework wit
h imperfect capital markets. A permanent fall leads to a steady-state
reduction in net foreign assets and a real depreciation, regardless of
whether the country is initially a net creditor or net debtor. On imp
act, the real exchange rate appreciates in the net debtor case, but ma
y either appreciate or depreciate in the net creditor case. The dynami
cs associated with a temporary shock depend not only on its duration b
ut also on the initial asset position. (C) 1998 Elsevier Science Ltd.
