Consider the Following Rule for Monetary Policy: R = 2 $\pi$

Consider the following rule for monetary policy: r = 2 percent + $\pi$ + 1/2(y - y*) /y* + 1/2( $\pi$ - $\pi$ *) , where r is the nominal federal funds rate, y is real GDP, y* is an estimate of the natural rate of output, $\pi$ is the inflation rate, and $\pi$ * is the inflation target. Other things the same, if the inflation rate rises by 1 percentage point this rule says the Fed should increase the nominal federal funds rate by
