When the world interest rate is negative a two-period economy cannot run perpetual current account deficits if its initial net foreign asset position is negative. 6. A country starts 2017 as a net creditor. The interest rate on its net asset position is 10 percent. That year, it runs a current account deficit.

Transcribed Image Text:Exercise 2.1 Indicate whether the following statements are true, false, or
uncertain and explain why.
1. An economy that starts with a positive net international investment
position will run a trade balance deficit at some point.
2. A country has been having trade balance deficits for 45 years. Four
decades ago, the country was a net creditor, but after so many trade
deficits it became a debtor. Clearly, this economy will have to run
trade surpluses at some point.
3. A two-period economy runs trade surpluses in both periods. It follows
that the current account in period 1 can have either sign (depending
on the magnitude of TB1), but the current account in period 2 must
be positive.
4. When the world interest rate is negative a two-period economy can
run perpetual trade deficits even if its initial net foreign asset position
is negative.
5. When the world interest rate is negative a two-period economy cannot
run perpetual current account deficits if its initial net foreign asset
position is negative.
6. A country starts 2017 as a net creditor. The interest rate on its net
asset position is 10 percent. That year, it runs a current account
deficit. It follows that the trade balance in 2017 was also negative.
