Go to the St. Louis Federal Reserve FRED database, and find data on the 1-Year Treasury Rate (GS1) and the GDP Deflator price index (GDPDEF). For (GS1), choose the frequency setting as “quarterly”; for (GDPDEF), set the units setting to “Percent Change From Year Ago"; and download both data series. For the questions below, assume inflation is a good proxy for inflation expectations.
a) From the current period of data available, compare inflation and the interest rate to what it was in 2005:Q1. Does the Fisher effect hold? Why or why not?
b) From the current period of data available, compare inflation and the interest rate to what it was in 1980:Q1. Does the Fisher effect hold? Why or why not?
c) (Advanced) Use the “scatterplot” function in Excel to create a scatterplot of inflation on the horizontal axis and the interest rate on the vertical axis. Use data from 1954:Q1 to the current available data. On the scatterplot, graph a fitted (regression) line of the data (there are several ways to do this; however, one chart layout has this option built in). Based on the fitted line, does the Fisher effect hold? Explain.
