Let it Bleed? by Brad DeLong

BERKELEY – In the 12 years of the Great Depression – between the stock-market crash of 1929 and America’s mobilization for World War II – production in the United States averaged roughly 15% below the pre-depression trend, implying a total output shortfall equal to 1.8 years of GDP. Today, even if US production returns to its stable-inflation output potential by 2017 – a huge “if” – the US will have incurred an output shortfall equivalent to 60% of a year’s GDP.

When I talk to my friends in the Obama administration, they defend themselves and the long-term macroeconomic outcome in the US by pointing out that the rest of the developed world is doing far worse. They are correct. Europe wishes desperately that it had America’s problems. 

Nevertheless, my conclusion is that I should stop calling the current episode the Lesser Depression. Yes, its shape is different from that of the Great Depression; but, so far at least, there is no reason to rank it any lower in the hierarchy of macroeconomic disasters.
