These exercises are based on data series in the data files USIVIacro_QuarterIy and USMacro_Monthly described in the Empirical Exercises in Chapters 14 and 15. Let Y i = ln(GDT)), R i denote the 3-month Treasury bill rate, and 
and 
denote the inflation rates from the CPI and Personal Consumption Expenditures (PCE) Deflator, respectively.
a. Using data on Y (the growth rate in GDP) from 1955:1 to 2009:4, estimate an AR(l) model with GARCH(1,1) errors.
b. Plot the residuals from the AR(1) model along with
, bands as in Figure 16.4.
c. Some macroeconomists have claimed that there was a sharp drop in the variability of Y around 1983, which they call the "Great Moderation." Is this Great Moderation evident in the plot that you formed in (b)
