单项选择题

A. the natural rate of unemployment will fall.
B. the natural rate of unemployment will rise.

答案
参考答案：C
解析：
There are two conclusions arising from modem analysis of the Phillips curve: Expansionary macroeconomic policies will cause inflation, without permanently reducing unemployment. When inflation exceeds expectations, unemployment falls below its natural levels. It is the difference between expected and actual inflation that influences unemployment, not the absolute magnitude of inflation.
