he 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. What was potential GDP for the third quarter of 2001? What was the actual level of real GDP for that quarter? What was the size difference between the two - the negative GDP gap? If the multiplier was 2 in that period, what was the size of the economy's recessionary gap?
