“The appreciation of the dollar from 2012 to 2017 had a negative effect on aggregate demand in the United States.” Is this statement true, false, or uncertain? Explain your answer.
John Maynard Keynes is among the most well-known economic theorists. Go to http://en.wikipedia.org/wiki/ John_Maynard_Keynes and write a one-page summary of his life and contributions.
Go to the St. Louis Federal Reserve FRED database, and find data on the budget deficit (FYFSD), the amount of federal debt held by the public (FYGFDPUN), and the amount of federal debt held by the Federal Reserve (FDHBFRBN). Convert the two “debt held” series to “Annual” using the frequency setting. Download all three series into a spreadsheet. Make sure that the rows of data align properly to the correct dates. Note that for the deficit series, a negative number indicates a deficit; multiply the series by –1 so that a deficit is indicated by a positive number. Manipulate the three series so that all data are given in terms of the same units (either millions or billions of dollars). To do this, if a series is in millions and you are converting it to billions, divide the series by 1,000. Finally, for each year, convert the two “debt held” series into one “changes in debt holdings by the public and the Federal Reserve” series by calculating, for each year, the difference in bond holdings from the preceding year.
a. Create a scatter plot showing the deficit on the horizontal axis and the change in bond holdings by the public on the vertical axis, using the data from 1980 through the most recent period of data available. Insert a fitted line into the scatter plot, and comment on the relationship between the deficit and the change in public bond holdings.
b. Create a scatter plot showing the deficit on the horizontal axis and the change in bond holdings by the Federal Reserve on the vertical axis, using the data from 1980 through the most recent period of data available. Insert a fitted line into the scatter plot, and comment on the relationship between the deficit and the change in Federal Reserve bond holdings.
c. Now repeat part (b), but create separate scatterplots for the period of 1980 to 2007, and 2008 to the most recent year. Comment on how, if at all, the monetizing of the debt is exhibited in the data. Do you think the relationship between the deficit and the change in bond holdings of the Federal Reserve has changed since 2008? Why or why not?
Suppose the money supply has been growing at per year, and nominal GDP, , has been growing at per year. The data are as follows (in billions of dollars):
Calculate the velocity for each year. At what rate is the velocity growing?
Suppose a given country experienced low and stable inflation rates for quite some time, but then inflation picked up and over the past decade had been relatively high and quite unpredictable. Explain how this new inflationary environment would affect the demand for money according to portfolio theories of money demand. What would happen if the government decided to issue inflation-protected securities?
