Problem 1, on page 106, 9th edition; on page 110, 10th edition. Calculate and graph the growth rate of total factor productivity since 1960 using FRED series RTFPNAUSA632NRUG. (Note that

this series is not the same as used in Table 3.1, but is similar.). How would you characterize the movements in productivity since 1960? How do recessions affect the growth rate of productivity? How was productivity affected by the oil shocks of 1973–1975, 1979–1980, 1990, and 2003-2008?
