The following are some data on the US economy take from the Economic Report of the President at https://www.gpo.gov. (Reports from before 2004 can be found at http://fraser.stlouisfed.org/publications/ERP/.)

Year	Unemployment Rate	Real Govt. Spending (billions)	Real Civilian Spending (billions)
1982	9.70%	$947.70	$3,672.60
1983	9.60%	960.1	3,943.60
1996	5.40%	1,257.90	5,670.50
1997	4.90%	1,270.60	5,920.80

a. Sketch a production possibilities frontier for the years 1982 and 1983, showing the traded-off between public sector (government) and private-sector (civilian) spending. Assume that the resource availability and technology were the same in both years, but notice that the unemployment rate was relatively high. b. Sketch a PPF for the years 1996 and 1997. Assume that the resource availability and technology were the same in both years but higher than 1982 and 1983. Note that the unemployment rate in the late 1990s was much lower than in the early 1980s. c. What lessons did you learn about the US economy of the past 20 years?
