4.Draw the graph of the per-worker production function and show the impact of the country adding more ofexisting types of capital for each worker. Assume that the initial amount of capital per worker is $100,000 andlabor productivity (Y/L) is $50,000. Also, what does this graph describe – labor productivity or K/L? 5.a. Carefully describe how the most recent U.S. jobs report (for February) leaves a puzzle for the Fed. b. Whathappened to the unemployment rate from January to February and why did it change? a.

But, real wage growth is very modest a best and many have quit the labor force. Thus, it may be sensible to continue to stimulate the economy. b. The unemployment rate fell (from 5.7% to 5.5%) and it fell due to people leaving the labor force.
