Econ 304 Summer 2012 Problem Set #7 Due by 11:59 PM MDT August 3 1. (3 points, Parts a and b. 4 points Part c) In April 2009, the U.S. unemployment rate was 8.9% a. According to one version of Okun's law, the GDP gap is twice the difference between the actual unemployment rate and the natural rate of unemployment. If the natural rate of unemployment was 5.4% in April 2009, calculate the GDP gap b. In April 2009, the inflation rate was about 0%. According to the Taylor rule, what were the recommended nominal and real federal funds rates? c. The nominal interest rate cannot fall below zero.
