A) I to H B) G to K C) I to J D) K to F E) J to H 26) Suppose the nominal interest rate is five percent, and the inflation rate rises from two percent to three percent. Might an increase in the nominal interest rate to 5.5 percent be consistent with the Taylor Principle? If not, what consequences might ensue? 27) A key concern of monetary policy makers is credibility. In particular, that people believe that inflation will not deviate far from a rate consistent with a healthy macroeconomy. How might credibility affect the slope of the monetary policy curve? 28) Suppose the economy is just recovering from a recession and all signs now point to robust growth.
