Go to http://rrecl.stlouisted.org. Download data for the following two variables: Real Gross Domestic Product, Annual percentage changes (click on "Categories," under "National Accounts" select "National Income & Product Accounts," then "GDP/GNP." Click on the series GDPCA," click on "Download series," and select "Percent change from Year Ago."); and (b) Bank Prime Loan Rate (under the category "Money, Banking, and Finance" select "Interest Rates," then "Prime Bank Loan Rate," click on and download the series "PRIME," then transform the monthly observations into annual data using the average function in Excel.) Use Excel to plot these two series on the same graph. What can you say by examining the graph? On average, do the two variables evolve in opposite directions?
