Part 1
a) Well done! From 2007 Q4 to 2009 Q2, real GDP fell from $15,762 to $15,134.1, or by -3.58%.
b) That's right! The deflator rose from 93.15 to 94.84, or 182%. If you put 1.74%, that's an approximation.
Part 2. Good! In each of those quarters, real GDP was lower than in the previous quarter.
Part 3. You had the right idea, but you assumed that real GDP grow at 3% for only one year
By the end of 2009, the economy had recovered slightly; however, the economy was still smaller than it was two years prior. From 2007 to 2009, real GDP had fallen from $15,762 billion to $15,356 billion. How deep was the recession?
Suppose that the long-run growth trend of real GDP was 3% per year. If the economy had grown at 3% per year since 2007, there was a shortfall of_____billion at the end of 2009.
