Time consistency of monetary policy in the open economy

This paper shows that in an open economy time-consistency problems are created not only by nominal government debt, but also by nominal private debt to foreigners. Given any external nominal debt, inflation redistributes wealth between domestic residents and foreigners. A government that cares about the welfare of its residents will be tempted to inflate whenever it or its residents have issued nominal debt to foreigners. An analysis of the U.S. net investment position shows that these international considerations have become increasingly relevant for the United States, because the recent external deficits have largely been financed in nominal terms.
