Keynesians, Please Exit Stage Left

"Back in February, amidst the neo-Keynesian rage to spend our way out of recession, I argued that stimulus wouldn’t stimulate. Pointing to the graph of the 10-year Treasury vs. 30-year mortgage rates I said that the government wouldn’t be able to flood the market with Treasurys without driving up interest rates. Higher rates on government debt imply higher rates for mortgages, which would hammer house prices and blow an ever-larger hole in bank balance sheets."
