I was just sent this disgusting article by a friend without comment. This is Paul Krugman trying to show how Keynesian economics has now shown its mettle based on the evidence that economies around the world are collapsing. Read this, and then I will come back with something more to say.
Last week the National Institute of Economic and Social Research, a British think tank, released a startling chart comparing the current slump with past recessions and recoveries. It turns out that by one important measure — changes in real G.D.P. since the recession began — Britain is doing worse this time than it did during the Great Depression. Four years into the Depression, British G.D.P. had regained its previous peak; four years after the Great Recession began, Britain is nowhere close to regaining its lost ground.
Nor is Britain unique. Italy is also doing worse than it did in the 1930s — and with Spain clearly headed for a double-dip recession, that makes three of Europe’s big five economies members of the worse-than club. Yes, there are some caveats and complications. But this nonetheless represents a stunning failure of policy.
And it’s a failure, in particular, of the austerity doctrine that has dominated elite policy discussion both in Europe and, to a large extent, in the United States for the past two years.
It was me not Krugman who wrote back in 2009 that if governments took the policy actions they took, then the outcome would be the disaster of major proportions that we now actually have. I said our economies would not recover. I said unemployment would remain high. I said investment would not return to anything like their previous rates. I argued prosperity would not return.
This was merely the application of classical business cycle theory which Keynes overturned in 1936. There may have been a few of these folk who lived on until the 1960s and 70s. But by then they were without policy relevance and had gone from the world of policy debate. Today all we have are various cuts of Keynesian theory and a vaguely classical Austrian economics that does not treat Say’s Law as anything other than peripheral. As for the classical theory of the cycle, there are few enough around who use this economic theory to make sense of events.
What really has embedded into me the recognition of how far from understanding what has gone wrong economic theory now is has been the return of this vindicated Keynesian triumphalism with hardly a word of response from any economist who might actually get a hearing in any paper or media outlet today.
I said in 2009 that what you see now is exactly what you would get if you did the things they were doing. And I have been meeting with economists during this brief trip of mine who are on the more market side of things but not one of them has a genuinely anti-Keynesian anti-stimulus theoretical story to tell. They still talk about monetary policy errors often going back to before the financial crisis. And they talk of debt and deficits. None tell a story of policy failure in 2009-11. Where is the critique of the stimulus? Where’s the theoretical flaw? What did governments do wrong? Is it just debt or the deficit, or is there something more?
Until I ventured forth on this trip, I had assumed that at least economists on the conservative side of the fence had a critique that even if not the same as mine, would at least focus on the stimulus and why it not only did not work but in fact made things worse. They would point out, in their own ways, that the depth of our current problems stemmed from the stimulus. Well forget it. Every economist I have met with so far thinks about macro using some version of aggregate demand as a reasonable proxy for events.
Well, I am meeting a whole lot more over the next two weeks and I am going to find out what it is with great specificity that they believe has gone wrong.
My question really is this. Just exactly what is wrong with what Krugman wrote? This is what I want to know. What’s wrong with Krugman and Keynes?
It’s two in the morning. I’m going to bed.
