ow has the size of government changed? To help answer this question, we recorded the U.S. federal budget receipts and outlays (billions of cur- rent dollars) for the years 1980 to 2007. a. Use a graphical technique to describe the receipts and outlays of the annual U.S. federal government budgets since 1980. b. Calculate the difference between receipts and outlays. If the difference is positive the result is a surplus; if the difference is negative the result is a deficit. Graph the surplus/deficit variable and describe the results.
