Pay set is to go up, or down, or stay the same – it all depends on how you measure it

We are heading into a so-called “living standards election” – without accurate data on living standards. Different sides will be able to tell whatever story they want.

We can expect to hear an awful lot about the closing gap between pay and inflation over the next few months as, inevitably and thankfully, on some measure we close in on a “cross-over point” where wages overtake price rises.  

But this poses the question: which measure of inflation and, indeed, which measure of pay?

Confusion abounds on this – and this provides the space for different political parties to choose numbers which stand up the story they want to tell about the recovery and living standards. Get ready for a war of competing statistics.

When it comes to pay, average wages (that is, mean pay across the economy or, more accurately, across employees) regularly get reported as if they relate to the experience of a typical worker in the economy. They don’t – they are skewed by whatever is going on at the top of the distribution. For this reason we need to look at median pay – that of the typical worker. While the period since the financial crisis have been marked by relatively even movements in pay across the earnings distribution, the typical experience in recent decades has been for the mean to significantly outpace the median, reflecting growing wage inequality. No one knows for sure how this will pan out during economic recovery, but few would be surprised if the historic relationship resumes.

The trickier issue is the measure of inflation that should be used to deflate trends in wages. And here there is a bit of disarray. This debate may sound nerdy – indeed, it is quite nerdy – but it matters and we are going to hear a lot about all this, so it’s worth reflecting on.

The Retail Price Index (RPI), introduced after WWII,  was traditionally considered the best measure for gauging what was happening to living standards, covering a wider suite of prices (and generally being higher) than the CPI which was introduced in the 1990s to meet the need for international harmonisation. Recently RPI has fallen out of favour. The formula it uses for aggregating prices (the Carli index, if you are into this sort of thing) has been fairly widely criticised and is thought to overstate inflation, leading the ONS to deem that it no longer qualifies as a National Statistic (though that hasn’t stopped the government from continuing to use it in relation to index-linked gilts and bonds).

This has left CPI as the main reported measure for inflation and it is used for uprating benefits, tax credits, pensions and tax thresholds (the government switched from RPI to CPI for uprating benefits from April 2011 and in doing so made a massive saving). But unlike RPI, CPI takes no account of a range of housing costs, such as mortgage interest payments. Arguably, it tells us quite a lot less about living standards.

The controversy about how to measure inflation is such that the UK Statistics Authority has established two reviews including one by the IFS’s Paul Johnson looking specifically at the arguments for using ‘cost of living’ or ‘cost of goods’ concepts in defining inflation. The former concept is likely to have more relevance for households and for the purposes of deflating pay and incomes; the latter is likely to be more useful from a macroeconomic perspective. As things stand, the various measures used in the UK tend to fall somewhere between these two camps.

Just to complicate matters further, two new measures have been already introduced: CPI-H (which adds an owner occupied housing element to CPI) and RPI-J (which maintains the RPI coverage but uses a more reliable formula similar to CPI). But neither of these measures is used by the government in policy formulation so when it comes to official wage projections we are left with the traditional choice between CPI and RPI.

To see how important – and politically relevant – these different measures can be consider this chart.

Source: OBR, Economic and Fiscal Outllook; and Resolution Foundation modelling

The CPI-deflated mean (average) wage projection is taken directly from the OBR’s latest Economic and Fiscal Outlook. It looks pretty rosy in the years ahead – at least compared to the recent past – and has caught the eye of many economic commentators. But it only tells part of the story.

If we want to get a sense of what this might mean for median pay we can adjust the average (assuming, as discussed above, that the relationship between the mean and median over the next few years is the same as that in the decade prior to the financial crisis).

What the chart shows is that if we then adjust this median wage figure for RPI inflation then pay looks set to fall in the years ahead. But if we use CPI it’s set to rise. And if we try and find some middle ground that avoids the narrowness of CPI or the unreliability of RPI, then we could use an imputed projection for RPI-J. (This assumes – imperfectly, but defensibly – that past relationships hold: holding constant the ratio between annual growth in the RPI and RPI-J in the years ahead, reflecting the relative stability of this ratio over the course of the history of the RPI-J). And under this RPI-J measure, pay is set to flat-line. So according to which measure of inflation you use wages are set to rise. Or flat-line. Or fall. Take your pick.

For now, at least, this leaves us in no man’s land. We are heading into a so-called ‘living standards election’ in which different sides will be able to tell whatever story they want about the prospects for wages depending on the measures used (with no official ‘best measure’). Add to this the fact that when it comes to what is happening to household incomes – a far superior measure of living standards – the only accurate data will be more than two years out of date by polling day. Given that some of our key economic measures are misleading and others are out of date, the electorate should stand ready to be bamboozled. Is this really the best we can do?

Chuka Umunna calls for "solidarity" among Labour MPs, whoever is voted leader

The full text of shadow business secretary Chuka Umunna's speech to Policy Network on election-winning ideas for Labour's future, and the weaknesses of the New Labour project.

There has never been an easy time to be a social democrat (or “democratic socialist” as we sometimes call ourselves in Britain). Whereas the right can demonise the poor and extol the virtues of the market, and the hard left can demonise the market and extol the role of the state, our position of constraining the domination of markets and reforming the state is, by definition, more complex.

It is nonetheless the case that social democracy has a historic responsibility, in every generation, to renew democracy and preserve a civic culture. This is achieved not through soundbites and slogans, but through the hard-headed development of a progressive politics that reconciles liberty and democracy, new comers and locals to our communities, business and workers, in a common life that preserves security, prosperity and peace.  This historic mission is all the more urgent now and my determination that we succeed has grown not weakened since our election defeat last May.

But, in order to be heard, it is necessary to make balanced and reasonable argument that both animates and inspires our movement, and which is popular and plausible with the people.  The first is pre-requisite to the second; and there is no choice to be made between your party’s fundamental principles and electability. They are mutually dependent - you cannot do one without the other.

We are in the midst of choosing a new leader and it is clear to anyone who has watched the UK Labour Party leadership election this summer that amongst a significant number there is a profound rage against Third Way politics – as pursued by the likes of Bill Clinton, Tony Blair, Gerhard Schröder and others - as a rejection of our fundamental values.

In the UK there is a view that New Labour accepted an uncritical accommodation with global capital that widened inequality, weakened organised labour and we were too close to the US Republicans and too far from the European left.

I do not believe this is fair, not least because we rescued many of our public services from the scrap heap when we came to office in 1997 and there were very significant achievements  we should celebrate.  New Labour renewed our National Health Service in a fundamental way; we built new schools and improved existing ones; we set up new children’s centres all over the country; we brought in a National Minimum Wage; we worked with others to bring peace to Northern Ireland; we introduced civil partnerships.  Just some of our achievements.

However, though we may take issue with the critique, I do not think we can simply dismiss out of hand those who hold critical views of New Labour. Like any government, the New Labour administration made mistakes - it could and should have achieved more, and done more to challenge the Right’s assumptions about the world. In the end, it is not unreasonable to be ambitious for what your party in government can achieve in building greater equality, liberty, democracy and sustainability. It is far better we acknowledge, not reject, this ambition for a better world, as we seek to forge a new politics of the common good fit for the future.

Realising our values in office has been disrupted by globalisation and the surge of technological forces that are displacing and reshaping industry after industry.

Some argue that globalisation as an ideological construct of the right. But we must recognise that we live in an increasingly integrated world in which markets have led to an unprecedented participation of excluded people in prosperity, a rise in living standards for hundreds of millions  of people and a literacy unprecedented in human history – this is particularly so in emerging economies like my father’s native Nigeria. And the internet has led to a level of accountability that has disturbed elites.

Yet, this has been combined with a concentration of ownership that needs to be challenged, of a subordination of politics that requires creative rather than reactive thinking, and these global forces have exacerbated inequalities as well as helped reduce poverty.

So it is important that we understand the sheer scale and impact of new technologies. At the moment we are engaged in a debate about Uber and its threat to one of the last vestiges of vocational labour markets left in London, those of the black taxi cabs and their attainment of 'The Knowledge'. But the reality is that within the next decade there will be the emergence of driverless cars so we have to intensify our exploration of how to support people in a knowledge economy and the realities of lifelong learning, as well as lifelong teaching. As people live longer we will have to think about how to engage them constructively in work and teaching in new ways.

Once again, I'm addressing all of this, Social Democracy requires a balanced view that domesticates the destructive energy of capital while recognising its creative energy, that recognises the need for new skills rather than simply the protection of old ones. A Social Democracy that recognises that internationalism requires co-operation between states and not a zero sum game that protectionism would encourage.

Above all, Social Democratic politics must recognise the importance of place, of the resources to be found in the local through which the pressures of globalisation can be mediated and shaped. Our job is to shape the future and neither to accept it as a passive fate nor to indulge the fantasy that we can dominate it but to work with the grain of change in order to renew our tradition, recognising the creativity of the workforce, the benefits of democracy and the importance of building a common life.  Sources of value are to be found in local traditions and institutions.

This also requires a recognition that though demonstration and protest are important,; but relationships and conversations are a far more effective way of building a movement for political change.

One of the huge weaknesses of New Labour was in its reliance on mobilisation from the centre rather than organising. It therefore allowed itself to be characterised as an elite project with wide popular support but it did not build a base for its support within the party across the country, and it did not develop leaders from the communities it represented. It was strong on policy but weak on strengthening democratic politics, particularly Labour politics.

Over half a million people are now members, supporters or affiliated supporters of our party, with hundreds of thousands joining in the last few weeks. Some have joined in order to thwart the pursuit of Labour values but many more have joined to further the pursuit of those values, including lots of young people. At a time when so many are walking away from centre left parties across the Western world and many young people do not vote let alone join a party, this is surely something to celebrate.

So it is vital that we now embrace our new joiners and harness the energy they can bring to renewing Labour’s connection with the people. First, we must help as many them as possible to become doorstep activists for our politics. Second, I have long argued UK Labour should campaign and organise not only to win elections but to affect tangible change through local community campaigns. We brought Arnie Graf, the Chicago community organiser who mentored President Obama in his early years, over from the U.S. to help teach us how to community organise more effectively. We should bring Arnie back over to finish the job and help empower our new joiners to be the change they want to see in every community – we need to build on the links they have with local groups and organisations.

I mentioned at the beginning that in every generation Social Democracy is besieged from left and right but the achievements of each generation are defined by the strength of a complex political tradition that strengthens solidarity through protecting democracy and liberty, a role for the state and the market and seeks to shape the future through an inclusive politics. Solidarity is key which is why we must accept the result of our contest when it comes and support our new leader in developing an agenda that can return Labour to office.

Yes, these are troubled times for social democrats. All over Europe there is a sense among our traditional voters that we are remote and do not share their concerns or represent their interests or values.  There is surge of support for populist right wing parties from Denmark to France, of more left wing parties in Greece and Spain and in Britain too. There is renewal of imperial politics in Russia, the murderous and abhorrent regime of ISIL in the Middle East, volatility in the Chinese economy and in Europe a flow of immigration that causes fear and anxiety.

But, the task of Social Democracy in our time is to fashion a politics of hope that can bring together divided populations around justice, peace and prosperity so that we can govern ourselves democratically. We have seen worse than this and weathered the storm. I am looking forward, with great optimism to be being part of a generation that renews our relevance and popularity in the years to come.
