Low growth leads to high debt, not the other way round

Charts of the day.

Two big holes have been left by the revelation of serious flaws in the Reinhart-Rogoff paper on austerity. The first is that the concept of a criticality at high levels of debt has been demolished. The original paper showed a massive drop in growth rates for countries with debt to GDP ratios over 90 per cent; that simply does not hold anymore. Insofar as the paper shows any negative association, it is linear – the step from 60 to 70 per cent is no more dangerous than the step from 85 to 95 per cent.

But there's also now an absence of notable economists claiming that high debt ratios cause low growth. In Reinhart and Rogoff's initial response to Herndon, Ash, and Pollin's paper, the authors point out that "we are very careful in all our papers to speak of 'association' and not 'causality'". That's true, but they have also not been shy about endorsing suggestions that there is an element of causality involved – and their paper has been widely misinterpreted as showing as such.

However, Arindrajit Dube presents pretty compelling evidence that the causality lies in the direction everyone but the austerians expected it to: slow growth causes high debt to GDP ratios, not the other way round. It's as simple as two charts:

 

The first image shows the correlation between the debt to GDP ratio in any given year, and the growth in the three years after it. Really low debt comes before high growth rates – but for nearly every other level of debt, the average growth in the next three years is 3 per cent.

Looking backwards, though presents a very different picture. There's strong linear relationship between low growth in the past and high debt-to-GDP ratios now.

And that's not surprising! As Dube writes:

One reason is just algebraic. The ratio has a numerator (debt) and denominator (GDP): any fall in GDP will mechanically boost the ratio. Even if GDP growth doesn’t become negative, continuous growth in debt coupled with a GDP growth slowdown will also lead to a rise in the debt-to-GDP ratio.

Besides, there is also a less mechanical story. A recession leads to increased spending through automatic stabilizers such as unemployment insurance. And governments usually finance these using greater borrowing, as undergraduate macro-economics textbooks tell us governments should do. This is what happened in the U.S. during the past recession.

The easiest way to cut the debt – in the only measure which matters, which is it in relation to the size of the economy – is to increase growth, at least back to the long-term trend. Going at it from the opposite direction, and cutting the debt in the hope it will bring growth back, is a recipe for disaster.

Want to beat child poverty? End the freeze on working-age benefits

Freezing working-age benefits at a time of rising prices is both economically and morally unsound. 

We serve in politics to change lives. Yet for too long, many people and parts of Britain have felt ignored. Our response to Brexit must respond to their concerns and match their aspirations. By doing so, we can unite the country and build a fairer Britain.

Our future success as a country depends on making the most of all our talents. So we should begin with a simple goal – that child poverty must not be a feature of our country’s future.

The Institute for Fiscal Studies projects that relative child poverty will see the biggest increase in a generation in this Parliament. That is why it is so troubling that poverty has almost disappeared from the political agenda under David Cameron, and now Theresa May.

The last Labour Government’s record reminds us what can be achieved. Labour delivered the biggest improvement of any EU nation in lifting one million children out of poverty, transforming so many lives. Child poverty should scar our conscience as much as it does our children’s futures. So we have a duty to this generation to make progress once again.

In my Barnsley constituency, we have led a campaign bringing together Labour party members, community groups, and the local Labour Council to take action. My constituency party recently published its second child poverty report, which included contributions from across our community on addressing this challenge.

Ideas ranged from new requirements on developments for affordable housing, to expanding childcare, and the great example set by retired teachers lending their expertise to tutor local students. When more than 200 children in my constituency fall behind in language skills before they even start school, that local effort must be supported at the national level.

In order to build a consensus around renewed action, I will be introducing a private member’s bill in Parliament. It will set a new child poverty target, with requirements to regularly measure progress and report against the impact of policy choices.

I hope to work on a cross-party basis to share expertise and build pressure for action. In response, I hope that the Government will make this a priority in order to meet the Prime Minister’s commitment to make Britain a country that works for everyone.

The Autumn Statement in two months’ time is an opportunity to signal a new approach. Planned changes to tax and benefits over the next four years will take more than one pound in every ten pounds from the pockets of the poorest families. That is divisive and short-sighted, particularly with prices at the tills expected to rise.

Therefore the Chancellor should make a clear commitment to those who have been left behind by ending the freeze on working-age benefits. That would not only be morally right, but also sound economics.

It is estimated that one pound in every five pounds of public spending is associated with poverty. As well as redirecting public spending, poverty worsens the key economic challenges we face. It lowers productivity and limits spending power, which undermine the strong economy we need for the future.

Yet the human cost of child poverty is the greatest of all. When a Sure Start children’s centre is lost, it closes a door on opportunity. That is penny wise but pound foolish and it must end now.

The smarter approach is to recognise that a child’s earliest years are critical to their future life chances. The weight of expert opinion in favour of early intervention is overwhelming. So that must be our priority, because it is a smart investment for the future and it will change lives today.

This is the cause of our times. To end child poverty so that no-one is locked out of the opportunity for a better future. To stand in the way of a Government that seeks to pass by on the other side. Then to be in position to replace the Tories at the next election.

By doing so, we can answer that demand for change from people across our country. And we can provide security, opportunity, and hope to those who need it most.

That is how we can begin to build a fairer Britain.
