"John Maynard Keynes has more to teach us about how to save the global economy than an army of modern Ph.D.s equipped with models of dynamic stochastic general equilibrium."
Not that I'm expecting graduate programs to reintroduce the history of economics anytime soon, but these stories are encouraging nonetheless.
And I'd forgotten how some prominent anti-Keynesians changed their tunes during the financial crisis:
"Richard Posner, the free-market federal appellate judge, wrote a 2009 article for the New Republic titled “How I Became a Keynesian.” Harvard University economist Martin Feldstein, a longtime deficit hawk who was President Reagan’s chief economic adviser, wrote an op-ed in the Washington Post in October 2008 saying, “The only way to prevent a deepening recession will be a temporary program of increased government spending.” The following February, Congress passed a $787 billion stimulus, albeit smaller than Keynesian economists advocated and with no Republican votes in the House. Even Germany, that bastion of austerity, put aside its misgivings and approved its biggest stimulus package ever."
