The St. Louis Federal Reserve Bank at https://www.research.stlouisfed.org provides data on both real GDP (chained 1996 dollars) and real GDP for the United States. Click on the "Economic Data-FRED" link at the top of the page, then select "Gross Domestic Product and Components." Now select GDP/GNP. Find the potential GDP and the actual GDP for the most recent quarter for which both are available. What was the size difference between the two - the negative/positive GDP gap? If the multiplier was 2 in that period, what was the size of the economy's recessionary/inflationary gap?
