The U.S. has had a deficit on the current account for nearly 37 years
and this has transformed the U.S. from a net creditor nation to an
international net debtor nation. What conclusions or assessments have
been drawn about this trend and its economic consequences?
International trade economists on the whole are not necessarily
alarmed by this trend, but increasingly some economists appear worried
about the likelihood of negative consequences.
There is no doubt that the U.S. has suffered measurable negative effects.
A positive aspect is that U.S. exceptionalism appears to be at work
since the income received on U.S. assets abroad exceeds the income the
U.S. pays on its liabilities to foreigners.
All of the above.
Only a and c.
