Should-Read: That the minority of academic economists who opposed fiscal stimulus from 2009-2011 were able to carry the day in the public sphere from 2010 on is a deep indictment of the economics profession—but more so of journalism, IMHO at least: Simon Wren-Lewis: Academic knowledge about economic policy is not just another opinion: “Why don’t we look at what has happened since the financial crisis…

Macroeconomists, having learnt the lessons of the 1930s, immediately recommended that policy makers do three things after the crisis: cut interest rates sharply, embark on fiscal stimulus and bailout banks. Policy makers took that advice in 2009, and as a result we avoided another Great Depression. Many said that rising government debt was sure to send interest rates on that debt rising: academic economists using basic ideas from Keynes said they would not and they were proved right. Many others said that Quantitative Easing (central banks creating money to buy government debt) would cause hyperinflation, but again academic economists looking at more modern New Keynesian models said that was nonsense and again they were right.

You might claim that in all this economists were just advocating what was obvious. The acid test came in and after 2010, when fiscal stimulus turned to austerity. What evidence we have suggests this move was opposed by a majority of academic economists, a majority that grew over time. There was a minority that supported austerity, at least for a time, and they gained a lot of publicity because politicians latched on to what they had to say. But the majority followed both textbook and state of art economics, and this majority was right. The recovery would have been stronger and faster if politicians had gone with this majority…
