The Economist: austerity in 2010 "threatened recovery"

The coalition against austerity is overwhelming.

It feels as though a rubicon has been somewhat crossed: it is now, undoubtedly, mainstream opinion that fiscal consolidation – austerity, to you or me – in the immediate aftermath of the greatest financial crisis in 80 years was a terrible idea.

The Economist's Free Exchange column was never particularly supportive of austerity, occasionally going against the grain of the magazine's main editorial line to do so. But this week is a particularly strong attack on the idea.

In the print column, Ryan Avent focuses on the IMF's declaration that, in times of crisis, the fiscal multiplier could be several times higher than previously thought, and takes a look at wider research in the area:

What that means is that austerity may hurt much more at some times than others. In a 2010 paper Alan Auerbach and Yuriy Gorodnichenko of the University of California, Berkeley argued that the fiscal multiplier may be negative during booms, meaning that spending cuts actually raise growth. In recessions, by contrast, it could be as high as 2.5. A study by Lawrence Christiano, Martin Eichenbaum and Sergio Rebelo of Northwestern University suggested that although the multiplier may hover at around 1 normally, it could rise to more than 3 when interest rates fall to near zero, leaving the central bank with less room to act.

We called the IMF's realisation that it had severely underestimated the multiplier the most important 68 words in its world economic outlook, and it appears Avent agrees.

In the blog which accompanies the column, he doubles down on the claimtwitter):

Policymakers suffered from a striking lack of perspective in opting to pursue broad austerity beginning in 2010. It was clear at the time that some economies needed to begin cutting debts immediately and that lots of economies would need to bring debt down eventually. But a look at global conditions should have indicated that the normal cushions against fiscal cuts were weaker than normal or absent. And so the decision by countries not facing immediate market pressure to start cutting alongside those that were seriously undermined the consolidation efforts of economies in truly dire straits and threatened recovery.

Avent has much more to say, particularly on the failure of central banks to play their role correctly, and both columns are well worth reading in full.

It's always hard to argue about what ought to have happened. Politically, everyone will point out that it holds little weight: no party can win an election based on the claim that they would have been better if they had won the last one; instead, they have to present forward-looking visions, and explain why the country will be better in five years time under them.

And economically, whether or not austerity was right is now meaningless; it happened, and failed, but the circumstances are changing daily. We are (far too slowly) climbing out of depression, and at some point the arguments for fiscal consolidation will get stronger, and a new discussion will need to be had.

Nonetheless, it is worth repeating: George Osborne was wrong, emphatically, obviously and inarguably. His decisions hurt the economy and the nation entirely unnecessarily, and he refused every possible opportunity to ameliorate that damage. Plan A isn't just failing, it has failed. Yet there has been no contrition, no apology, and not even a hint of understanding. All there is is a lesson for future Chancellors: Don't Do This.

Police shoot man in parliament

A man carrying what appeared to be a knife was shot by armed police after entering the parliamentary estate. 

From the window of the parliamentary Press Gallery, I have just seen police shoot a man who charged at officers while carrying what appeared to be a knife. A large crowd was seen fleeing from the man before he entered the parliamentary estate.

After several officers evaded him he was swiftly shot by armed police.

Ministers have been evacuated and journalists ordered to remain at their desks.
