Some economists argue suddenly reducing money supply growth is a costly way to
reduce inflation and that it may not work. For example, if a government cuts money
growth but makes no real fiscal reforms, people will expect the government will

promise to fight inflation will not be credible. Explain why credibility is important to a
reduction in the inflation rate.
