Chapter 17: Q. 16 (page 468)
According to the Greenspan doctrine, under what conditions might a central bank respond to a perceived stock market bubble?
Short Answer
The stock market bubble raises asset prices and causes other macroeconomic fluctuations that do not need to be directly responded to by the central bank; rather, the central bank should respond by formulating appropriate policies.
Therefore, monetary policy allows for long-term fluctuations to be controlled over time.
