The Treasury has a point on living standards — but it ignores the role of inequality

Inequality is a more important explanation than rising employer costs for why the wages of the typical worker have fallen behind GDP.

One of the big surprises in today’s Autumn Statement lies in the new OBR projections. Growth has been revised up as expected—at least in the short-term. But wage forecasts are down. Amazingly, after today’s largely positive economic news, the squeeze on wages is now going to be even longer than the OBR thought in March. The updates reflect the OBR’s revised view that the crisis has caused a larger and more permanent hit to productivity than previously thought. They will also add momentum to a debate that was already gaining pace before today’s announcement: is the link between economic growth and wage growth weakening? And how soon will a recovery bring an end to the squeeze?

Earlier this week, the Treasury entered this debate by briefing its own new analysis of how the link between economic growth and living standards has changed over the longer term. Their top-line message was clear: there’s been no fundamental shift in the relationship between growth and pay. Instead, wages have simply been squeezed by rising employer costs — both pension contributions and, more pointedly, the increases in employer National Insurance introduced under Labour. But how adequate an explanation do employer costs really provide for the changing link between GDP and pay?

We can answer this by looking at a report written for the Resolution Foundation by Professor John van Reenen and Joao Paulo Pessoa. Although the paper is referenced in HMT’s briefing, they have not gone as far as replicating the wider analysis the paper covered.

In the fuller analysis we see that there are three potential culprits for why the link between GDP growth and wage growth has weakened over time. First there’s the question of whether the share of national income going into workers’ compensation has been falling, and the share going to profits rising. If so, the compensation workers receive will have lagged growth in GDP. Second, there’s the fact that not all compensation goes into wages—some goes into pension contributions and some goes into employer National Insurance. This is HMT’s focus. Third, there’s the fact that wages are not distributed evenly across the economy. If those at the top get a growing share of wages over time, wages for typical workers in the middle— at the median —are likely to lag behind.

So here, in three simple charts, is the story of how much each of these things have mattered in the last 30 years.Chart 1 shows how trends in GDP compare to trends in average worker compensation since 1972. If the share of national income going to labour was falling, we’d see a growing gap between the two. We don’t see much of this. At the start of the crisis in 2008, overall compensation had only fallen slightly behind GDP. This suggests that changes in the share of GDP going to labour don’t account for much of what’s going on.

Chart 1: The role of a falling labour share—GDP and average total compensation

What about the non-wage costs that the Treasury focuses on? Chart 2 shows that a gap has indeed opened up between a measure of average compensation, which includes these costs, and average wages, which doesn’t. This confirms HMT's basic claim that non-wage employer costs have risen, squeezing the amount left over for pay. Not all of this change is about employer NICs —rising pension contributions have played a bigger role. This is of course no bad thing in itself, although its generational implications are harsh for the young people taking a hit to their pay to fill historic pension fund deficits. Either way, the trade-off between these costs and wages is clear.

Chart 2: The role of employer costs — average total compensation and average wages

That leaves the question of how wages are distributed by the labour market. Chart 3 shows how trends in median wages—the pay of the worker in the middle of the distribution—compare to trends in average (mean) wages, which also capture growth in wages at the very top. The gap between the two shows the extent to which inequality accounts for the typical worker falling behind economic growth. As we can see, this gap is the biggest of the three. Inequality is a more important explanation than rising employer costs for why the wages of the typical worker have fallen behind GDP.

Chart 3: The role of inequality—mean wages and median wages

What should we make of all this? There’s no disguising the fact that it makes for a lousy whodunit; no single factor is to blame. And of course today’s new OBR forecasts for wages owe as much to the unusual dynamics of our post-crisis labour market as they do to the longer-term story we see in these charts.

But the findings also show how much we need a more serious, less partisan debate about these fundamental changes in how our economy works. There will be those on both sides of the political aisle that don’t much like the implication of these findings. For some on the left, it is appealing to turn to a falling labour share as an explanation for wages falling behind. They see the owners of capital hoarding ever more profits, squeezing out workers. But in 2008, such changes only accounted for around a fifth of the gap that had opened up between GDP and median pay since 1972. On the other hand, non-wage costs accounted for more than a quarter (27 per cent). That means accepting the basic truth in the Treasury account: rising employer costs put pressure on pay.

But we also need to challenge the temptation, more common on the right, to say that high or rising employer costs are a simple cause of the weakening link between growth and wages. This is inexcusably partial. Inequality accounted more than half (53 per cent) of the gap that had opened up between GDP growth and median wage growth from 1972 to 2008. Yet inequality has so far been missing entirely from government briefing on this issue. If there are still those who think high levels of inequality aren’t relevant to the living standards of ordinary workers, they too need to wake up.

An unmatched font of knowledge

Edinburgh’s global reputation as a knowledge economy is rooted in the performance and international outlook of its four universities.

As sociologist-turned US Senator Daniel Patrick Moynihan recognised when asked how to create a world-class city, a strong academic offering is pivotal to any forward-looking, ambitious city. “Build a university,” he said, “and wait 200 years.” He recognised the long-term return such an investment can deliver; how a renowned academic institution can help attract the world. However, in today’s increasingly globalised higher education sector, world-class universities no longer rely on the world coming to come to them – their outlook is increasingly international.

Boasting four world-class universities, Edinburgh not only attracts and retains students from around the world, but also increasingly exports its own distinctively Scottish brand of academic excellence. In fact, 53.9% of the city’s working age population is educated to degree level.

In the most recent QS World University Rankings, the University of Edinburgh was named as the 21st best university in the world, reflecting its reputation for research and teaching. It’s a fact reflected in the latest UK Research Exercise Framework (REF), conducted in 2014, which judged 96% of its academic departments to be producing world-leading research.

Innovation engine

Measured across the UK, annual Gross Value Added (GVA) by University of Edinburgh start-ups contributes more than £164m to the UK economy. In fact, of 262 companies to emerge from the university since the 1960s, 81% remain active today, employing more than 2,700 staff globally. That performance places the University of Edinburgh ahead of institutions such as MIT in terms of the number of start-ups it generates; an innovation hothouse that underlines why one in four graduates remain in Edinburgh and why blue chip brands such as Amazon, IBM and Microsoft all have R&D facilities in the city.

One such spin out making its mark is PureLiFi, founded by Professor Harald Haas to commercialise his groundbreaking research on data transmission using the visible light spectrum. With data transfer speeds 10,000 times faster than radio waves, LiFi not only enables bandwidths of 1 Gigabit/sec but is also far more secure.

Edinburgh’s universities play a pivotal role in the local economy. Through its core operations, knowledge transfer activities and world-class research the University generated £4.9bn in GVA and 44,500 jobs globally, when accounting for international alumni.

With £1.4bn earmarked for estate development over the next 10 years, the University of Edinburgh remains the city’s largest property developer. Its extensive programme of investment includes the soon-to-open Higgs Centre for Innovation. A partnership with the UK Astronomy Technology Centre, the new centre will open next year and will supply business incubation support for potential big data and space technology applications, enabling start-ups to realise the commercial potential of applied research in subjects such as particle physics.

It’s a story of innovation that is mirrored across Edinburgh’s academic landscape. Each university has carved its own areas of academic excellence and research expertise, such as the University of Edinburgh’s renowned School of Informatics, ranked among the world’s elite institutions for Computer Science. 

The future of energy

Research conducted into the economic impact of Heriot-Watt University demonstrated that it generates £278m in annual GVA for the Scottish economy and directly supports more than 6,000 jobs.

Set in 380-acres of picturesque parkland, Heriot-Watt University incorporates the Edinburgh Research Park, the first science park of its kind in the UK and now home to more than 40 companies.

Consistently ranked in the top 25% of UK universities, Heriot-Watt University enjoys an increasingly international reputation underpinned by a strong track record in research. 82% of the institution’s research is considered world-class (REF) – a fact reflected in a record breaking year for the university, attracting £40.6m in research funding in 2015. With an expanding campus in Dubai and last year’s opening of a £35m campus in Malaysia, Heriot-Watt is now among the UK’s top five universities in terms of international presence and numbers of international students.

"In 2015, Heriot-Watt University was ranked 34th overall in the QS ‘Top 50 under 50’ world rankings." 

Its established strengths in industry-related research will be further boosted with the imminent opening of the £20m Lyell Centre. It will become the Scottish headquarters of the British Geological Survey, and research will focus on global issues such as energy supply, environmental impact and climate change. As well as providing laboratory facilities, the new centre will feature a 50,000 litre climate change research aquarium, the UK Natural Environment Research Council Centre for Doctoral Training (CDT) in Oil and Gas, and the Shell Centre for Exploration Geoscience.

International appeal

An increasingly global outlook, supported by a bold international strategy, is helping to drive Edinburgh Napier University’s growth. The university now has more than 4,500 students studying its overseas programmes, through partnerships with institutions in Hong Kong, Singapore, China, Sri Lanka and India.

Edinburgh Napier has been present in Hong Kong for more than 20 years and its impact grows year-on-year. Already the UK’s largest higher education provider in the territory, more than 1,500 students graduated in 2015 alone.

In terms of world-leading research, Edinburgh Napier continues to make its mark, with the REF judging 54% of its research to be either world-class or internationally excellent in 2014. The assessment singled out particular strengths in Earth Systems and Environmental Sciences, where it was rated the top UK modern university for research impact. Taking into account research, knowledge exchange, as well as student and staff spending, Edinburgh Napier University generates in excess of £201.9m GVA and supports 2,897 jobs in the city economy.

On the south-east side of Edinburgh, Queen Margaret University is Scotland’s first university to have an on-campus Business Gateway, highlighting the emphasis placed on business creation and innovation.

QMU moved up 49 places overall in the 2014 REF, taking it to 80th place in The Times’ rankings for research excellence in the UK. The Framework scored 58% of Queen Margaret’s research as either world-leading or internationally excellent, especially in relation to Speech and Language Sciences, where the University is ranked 2nd in the UK.

In terms of its international appeal, one in five of Queen Margaret’s students now comes from outside the EU, and it is also expanding its overseas programme offer, which already sees courses delivered in Greece, India, Nepal, Saudi Arabia and Singapore.

With 820 years of collective academic excellence to export to the world, Edinburgh enjoys a truly privileged position in the evolving story of academic globalisation and the commercialisation of world-class research and innovation. If he were still around today, Senator Moynihan would no doubt agree – a world-class city indeed.
