问题如下：
Suppose the GDP deflator is less than 1, an economist may conclude that:
选项：
A.the economy is in the period of stagflation.
B.the economy is in the period of deflation.
C.the economy is in the period of inflation.
解释：
B is correct.
When real GDP exceeds nominal GDP, the GDP deflator is less than 1. In this condition, prices decrease and deflation occurs.
考点：GDP deflator
解析：当GDP deflator小于1，意味着名义GDP已经小于真实的GDP，此时一国经济通常运行在通缩的阶段。
怎么才能记住nominal是当年，real是基期呢，从单词上来看real更像是实际的。。。哎
