At the close of last week’s G20 Summit, U.K. Prime Minister David Cameron warned that we’re on the verge of another global recession, citing problems like looming deflation, falling prices, and rising protectionist sentiment. This list evokes a sense of déjà vu: not about the Great Recession, but the GreatDepression. That was the last time we ever seriously worried about disinflation, along with every practically other aspect of economic performance raising alarm bells today: low interest rates, weak investment, slow productivity growth, and chronic labor force detachment.
To be sure, this isn’t an easy comparison to swallow. The Great Depression is the ultimate measuring rod of economic catastrophe to which every other downturn is compared. But as time goes by and forecasts of full recovery keep getting deferred like an ever-fading mirage, it’s one worth examining. How does the Great Depression of the 1930s compare with the Great Recession of the 2010s? Let’s look at the GDPs of the U.S., U.K., and continental Western Europe from 1929 on and from 2007 on, using the base year as an index.
