Beauregard has concerns about the firm’s experiences
during currency crises. She recalls reading a study produced by the IMF that an
impending currency crisis is signaled by numerous economic variables. She makes
the following statements with regard to some of these variables:
1.
Trade
balances exhibit substantial decline prior to the crisis.
2.
A
country has distinctive economic growth patterns ahead of the crisis.
3.
Inflation
is significantly higher in the pre-crisisperiod.
Which of Beauregard’s statements regarding a
currency crisis is the most accurate?
选项：
A.Statement 3
Statement 2
Statement 1
解释：
Statement 3 is the most accurate. Inflation tends to be significantly higher in pre-crisisperiods compared with tranquil periods.
解析：A选项最准确的。与平静时期相比，危机前时期的通胀率往往要高得多。
C选项错误，the terms of trade而非Trade balances下降。如果是Trade balances大幅下降，表明危机已经发生，就不是危机的信号了。
B选项错误，因为危机发生前，经济不会有什么额外的增长。
请问term of trade和trade balance 区别是啥？
