The Great Depression and the Great Recession compared
So I teach a course on the two (old syllabus here). One of the initial classes looks at Eichengreen and O'Rourke's comparison of the two events, and how, even though at the beginning the shock seemed similar, the recovery has been faster the second time. O'Rourke had noticed in his blog last year that the current recovery started way before, but has been so slow that now the 1930s look better when industrial output (rather than GDP) is used as a measure. Below the same data for the US economy (he uses world industrial output).
