Former MPC member Posen: Forward guidance no substitute for policy

This is not the hope you're looking for.

In a piece written for the CEPR pamphlet "Is Inflation Targeting Dead? Central Banking After the Crisis", former Bank of England Monetary Policy Committee member Adam Posen has dismissed the idea of forward guidance for monetary policy as a "gimmick".

Forward guidance is the idea that a monetary policy committee can pre-commit to a certain course of policy in order to drive outcomes in the direction they want. It's a particularly trendy idea right now, driven, Posen writes, "by the question about whether central banks should be explicitly focusing on GDP (or unemployment) as well as inflation".

If forward guidance works as it should, then a bank can boost the economy by assuaging fears amongst investors that monetary policy will be tightened shortly. Armed with that guidance, they will (ideally) go off and take actions which strengthen the economy, which they may not have taken if they were expecting an imminent rise in interest rates.

But Posen points out that that rarely happens. He cites three examples, in Canada, Sweden and the US, where forward guidance has been issued, but later statements from the central bank have served to instil doubt in the markets. For instance, in the US:

The Federal Reserve recently embraced a version of pre-commitments when the FOMC announced in November 2012 that they were switching to a ‘thresholds model’. Namely, they would not raise rates until unemployment fell unless the inflation threshold was violated.
I think that was the right stance of policy. Then we saw the next month, based on some comments in the minutes from the FOMC meeting, the market sold off.

His evidence is backed up by the fact that in the UK – where pre-commitment is explicitly foresworn – "the impact of quantitative easing was very closely comparable… to that of the US". As a result, Posen, writes, "the bottom line lesson… is that talk is cheap."

Of course, it may still be the case that in some hypothetical situation where the central bank managed to release a series of statements which were all consistent with the forward guidance in the eyes of the market that the policy would have the desired effect. But, he argues, "believing that jawboning had some effect is not the same as believing that it is an independent tool of monetary policy with a lasting and credible effect."

The intervention may come as a disappointment to incoming Bank of England governor Mark Carney. Posen explicitly calls out Carney for placing too much faith in forward guidance, and attributes it to "frustration – the lack of recovery despite massive monetary-policy shifts." It's certainly true that many of Carney's supporters are hoping that this will be the policy shift which actually works, but Posen provides a hope of his own:

The fact is we could have pursued more aggressive monetary policy, achieved better goals and been totally consistent with the current inflation target…

Forward guidance is no substitute for sufficient policy action.

Responding to George Osborne's tax credit U-turn should have been Labour's victory lap

He changed the forecast, we changed the weather. But still it rains.

The Labour Party should have rested on its laurels in the Autumn Statement. While Gideon name checked his Tory colleagues for their successful lobbying, he should have been reading out the names of Labour members who changed his position.  I'll let the Tories have the potholes, (even though it was in Labour manifesto) but everything else was us. 

He stopped his assault on tax credits. Not because he woke up in his mansion in a cold sweat, the ghost of Christmas Future at the foot of his bed, ringing out the names of the thousands and thousands of children he would plunge into poverty. Nah, it's not that. It's as my sons might say "no way George, you got told!" The constant pressure of the Labour Party and a variety of Lords in a range of shades, supported by that media we are all meant to hate, did for him. It's the thousands of brilliant people who kept the pressure up by emailing politicians constantly that did it. Bravo us, boo nasty George!

As Baron Osborne thanked the Tory male MP for his brilliant idea, to spend the Tampax tax on women's services, I wanted to launch a tampon at his head. Not a used one you understand, I have some boundaries. He should have credited Paula Sheriff, the Labour MP for making this change. He should have credited all the brilliant women's groups, Yvette Cooper, Stella Creasy, Caroline Lucas and even little old me, for our constant, regular and persistent pestering on the subject of funding for refuges and women's services. 

On police cuts, his side should not have cheered him at all. We are now in a position when loud cheers are heard when nothing changes. So happy was his side that he was not cutting it, one can only conclude they really hate all the cutting they do. He should not have taken a ridiculous side swipe at Andy Burnham, but instead he should have credited the years and years of constant campaigning by Jack Dromey. 

I tell you what Georgie boy can take credit for, the many tax increases he chalked up. Increases in council tax to pay for huge deficit in care costs left by his cuts. Increases in the bit of council tax that pays for Police. Even though nothing changed remember. When he says levy or precept it's like when people say I'm curvy when they mean fat. It's a tax. 

He can take credit for making student nurses pay to work for free in the NHS. That's got his little privileged fingers all over it. My babies were both delivered by student midwives. The first time my sons life was saved, and on the second occasion my life was saved. The women who saved us were on placement hours as part of their training, working towards their qualifications. Now those same women, will be paying for the pleasure of working for free and saving lives. Paying to work for free! On reflection throwing a tampon at him is too good, this change makes me want to lob my sons placenta in his face.

Elsewhere in Parliament on Autumn Statement day Jeremy Hunt, capitulated and agreed to negotiate with Student Doctors. Thanks to the brilliant pressure built by junior doctors and in no small part Heidi Alexander. Labour chalks up another win in the disasters averted league.

I could go on and on with thanks to charities, think tanks, individual constituents and other opposition MPs who should have got the autumn cheers. We did it, we were a great and powerful opposition, we balanced the pain with reality. We made Lord sorry the first Lord of the Treasury and his stormtroopers move from the dark side. We should have got the cheers, but all we got was a black eye, when a little red book smacked us right in the face.
