A macroeconomic analysis of foreign assets and foreign liabilities

Although an increase in foreign assets and a decrease in foreign liabilities both increase a nation's net foreign assets (NFA), they have alternative macroeco- nomic transmission mechanisms: while an increase in foreign assets is expansionary, the effect of a decrease in foreign liabilities is mixed due to the asymmetry between its income effect and wealth effect on aggregate demand. It is the relative strengths of the NFA's wealth effect and income effect that determine the existence and natures of a saddle-point equilibrium in the NFA-real balance space as well as its comparative statics. The cointegration analysis suggests that in the 1990s, foreign liabilities bear more weight than foreign assets in the US NFA movement whereas the opposite holds for the case of Japan; therefore, correcting NFA imbalances calls for accelerated money growth and fiscal expenditure pruning in the U.S. but for the opposite policy responses in Japan. © Springer Science + Business Media, LLC 2007.
