问题如下：
Based on Exhibit 1 and Wakuluk’s assumptions about short-term rates and expected inflation, short-term rates in Country X are most likely to be:
选项：
A.low and bottoming.
B.above average and rising.
C.approaching a peak.
解释：
A is correct. Country X is predicted to be in the initial recovery phase of the business cycle, which suggests short-term (money market) rates are low or bottoming. Inflation is procyclical. It accelerates in the later stages of the business cycle when the output gap has closed, and it decelerates when a large output gap puts downward pressure on wages and prices, which often happens during a recession or the early years afterward. As long as short-term interest rates adjust with expected inflation, cash is essentially a zero-duration, inflationprotected asset that earns a floating real rate, which is typically procyclical. Wakuluk assumes short-term interest rates adjust with expected inflation and are procyclical. Tus, short-term rates are most likely to be low and bottoming if Country X is in the initial recovery phase of the business cycle.
X国预计将处于商业周期的初步复苏阶段，这意味着短期(货币市场)利率处于低位或见底。通货膨胀是顺周期。在商业周期的后期，当产出缺口缩小时，经济增长会加速;当巨大的产出缺口对工资和价格构成下行压力时，经济增长会减速，而这种情况通常发生在经济衰退或衰退后的最初几年。
只要短期利率随着预期的通货膨胀进行调整，现金基本上就是一种零存续期、受通货膨胀保护的资产，因为它的实际利率是浮动的，还是顺周期的。Wakuluk假设短期利率会随着预期的通货膨胀而调整，并且是顺周期的。如果X国正处于商业周期的初步复苏阶段，那么短期利率最有可能处于低位和底部。所以A选项正确。
- Output GAP 是？？ Output Gap = Actual GDP - Potential GDP
- 答案中提到“a large output gap puts downward pressure on wages and prices” ，这是因为经济过热（生产过多导致过剩）造成的吗？如果不是，是什么原因导致的？
谢谢
