Exercise 5 parts a-d (i-v) d. LY, for some integer k> 0 5. The following table contains quarterly nominal GDP in U.S. (billions of dol- lars). Let Y, denote the GDP at time t and let y, = ln (Y). (Show your calculations in a spreadsheet, e.g., in Microsoft Excel.) a. Plot the time series (Y). Can the underlying stochastic process be weakly b. Calculate the growth rate of nominal GDP by computing the percentage c. Plot the natural logarithm...
Exercise 6,7,8, and 9 use data from exercise 5 for exercise 6. use data from the graph for 7,8,9 d. LY, for some integer k> 0 5.
