Abstract
International financial integration allows countries to become net creditors or net debtors with respect
to the rest of the world. In this paper, we show that a small set of fundamentals--shifts in relative
output levels, the stock of public debt and demographic factors--can do much to explain the evolution
of net foreign asset positions. In addition, we highlight that “external wealth” plays a critical role in
determining the behavior of the trade balance, both through shifts in the desired net foreign asset
position and the investment returns generated on the outstanding stock of net foreign assets. Finally,
we provide some evidence that a portfolio balance effect exists: real interest rate differentials are
inversely related to net foreign asset positions.
