Today’s apologists for socialism still won’t acknowledge the lessons of the Berlin Wall

Today’s apologists for socialism still won’t acknowledge the lessons of the Berlin Wall

The media has been awash over the past week with stories about the thirtieth anniversary of the fall of the Berlin Wall.

My favourite vignette concerns a couple living in East Berlin who were delighted to have a telephone installed in their apartment only weeks before the Wall came down. They had been on the waiting list for 19 years.

This captures the essence of socialism. The system could generate a tolerable standard of living for citizens, but it was grossly inefficient and run for the benefit of the producers rather than the consumers.

The old nationalised industries in Britain also offered us a glimpse of what life would be like under socialism. Under British Rail, new heating stoves really were installed in station waiting rooms on the very day that the line was closed to traffic for ever.

In the 1970s, people routinely waited at least six months for the nationalised telecoms company to install a domestic phone line.

This “producer-just” attitude persists. Today’s Labour leadership has, for example, defended firefighters in the face of the recent damning criticism of their performance in the Grenfell Tower tragedy. For Jeremy Corbyn and John McDonnell, the interests of the producers — the public sector workers, even the fire chief who could retire at 50 with a pension of £140,000 a year — come first.

Some will feel that this is unfair to socialism. Socialism in practice may have had its faults (such as the liquidation of nearly 100 million people by their own governments), but a better, different kind of socialism is apparently on offer in the future.

Remarkably, the leaders of the Communist Parties in Eastern Europe appear to have believed the same thing. The ideologists in their Politburos described countries such as East Germany as examples of “actually existing” socialism — in contrast to the nirvana which would exist at some unspecified time in the future.

But we can only judge a system by its performance in practice, not by some Platonic ideal of what true believers imagine it might do. Everywhere it has been tried, socialism has been a failure. This simple fact cannot be repeated too often, particularly to younger generations to whom 1989 may seem as remote as the days of the Roman Empire.

Modern history has provided us with a whole series of what are termed natural experiments.

We cannot set up (as in the natural sciences) a laboratory in which one society is started up on socialist lines and the other on capitalist ones, and then observe their performances over time.

But we can observe the United States and the Soviet Union, West and East Germany, South and North Korea, China when it was purely socialist and China when it subsequently embraced a market-oriented economy.

In every single case, capitalism has delivered better outcomes: higher living standards, longer life expectancy, more holidays, more provision of health and education — more of almost everything except slave labour and environmental pollution.

Capitalism can be criticised, but its faults are nothing compared to those of socialism.

From World War II to the financial crisis, our institutional memory is fading fast

From World War II to the financial crisis, our institutional memory is fading fast

The young contestants on Lord Sugar’s reality TV show The Apprentice sparked outrage last week.

They appeared to have virtually no knowledge about the Second World War.

The online clips of the sequence capture to perfection their expressions of bovine outrage at even being expected to know such an esoteric thing as how long the War lasted. For many viewers, it was a powerful argument for an immediate raising of the voting age to at least 35.

Trying to be fair, I reflected on my own knowledge of the Boer War. The gap between that and my birth is not that much more than the one between World War II and Lord Sugar’s wannabes.

I have to confess that it is very sketchy. I know it was around 1900. The Boers nearly pulled off a shock victory, but our boys pipped them in extra time. And there was a siege at somewhere called Mafeking.

That said, the Second World War is of far more historic significance than Britain’s colonial skirmishes. The participants in The Apprentice might, one would think, be expected to know more about it.

Their ignorance reflects a more general trend towards what can be described as a shortening of cultural memory.

This can be seen in many seemingly unrelated ways.

Baby names, for example, are important indicators of culture. The example may seem slightly frivolous but, as the American polymath Stephen Pinker has written, the choice of name “encapsulates the great contradiction in human life: between the desire to fit in and the desire to be unique”.

Whenever there is a royal birth in the UK, the name given to the new baby enjoys a surge in popularity as people copy what is fashionable. But there is also the desire to give your baby a distinctive name.

In the twenty-first century, the turnover in popularity of names has increased dramatically.  It was steady for almost the whole of the twentieth century – once a name had made it into the top 10, say, it tended to stay there a long time. But the “churn” is now running at a rate nearly 10 times greater.

The outcomes of behaviour on the internet provide a more obvious example. At any point in time, the most popular memes on Twitter or the most viewed videos on YouTube are often millions of times more popular than the average. But their popularity is ephemeral.

In what many would regard as far more serious areas of economic activity, away from popular culture, this shortening of collective memory may have disturbing consequences for all of us.

In financial markets, for example, there is a traditional tale that a crisis happens precisely when the institutional memory of the last crisis has faded. But if traders and decision-makers develop shortened memories, crises could become more frequent.

Already bodies such as the International Monetary Fund are warning about the build-up of private sector debt, even though it is scarcely a decade since such debt precipitated the global financial crisis.

The apparent ignorance of The Apprentice candidates offers a warning to us all.

The economic impact of Brexit tariffs only tells us half the story

Posted by on October 31, 2019 in Blog, Brexit, Economy | Comments Off on The economic impact of Brexit tariffs only tells us half the story

The economic impact of Brexit tariffs only tells us half the story

Brexit is about much more than the economic costs and benefits, but the idea that the former dramatically outweigh the latter has become the received wisdom in much of the media.

Report after report emerges which purports to show that, under any of the various trade arrangements envisaged, the UK will be worse off as a result of Brexit.

These studies are not wrong. They all use perfectly standard economic theory to arrive at their conclusions. But they are misleading.

The real problem is that they miss out key bits of the story. We can think of the classic tale of the person dropping his car keys in the street at night. He only looks for them under the street lamp, where the light is.

In the same way, standard economic analysis of Brexit only illuminates part of the landscape.

The explanation of why trade occurs between countries was given 200 years ago by the great English economist David Ricardo. It is still the basis of the modern economist’s understanding of trade.

Ricardo imagined, to illustrate his theory, a world with just two countries and two products. His examples were England and Portugal, and cloth and wine – but they could have been any countries and any products.

Ricardo asked a simple but profound question. If England could produce both cloth and wine more efficiently than Portugal, why would trade take place at all? How could the more efficient country, England, benefit from trade?

His answer introduced the fundamental concept of comparative advantage. England had an absolute advantage in producing both cloth and wine, but the country should choose to specialise in producing the one in which its advantage compared to Portugal was bigger.  Both would benefit if England produced only cloth and Portugal only wine, and they traded.

Economics has moved on in the past two centuries, but the concept of comparative advantage, modified by factors such as the distance between countries, is still seen as a key determinant of trade patterns.

In terms of Brexit, introducing complexities like tariffs into the picture essentially affects the amount which is traded, and not the structure of trade in terms of who sells what to who.

If the basic pattern of trade is fixed by comparative advantage, then if Brexit means higher tariffs for the UK, as a country we will lose out. In a nutshell, this is what lies behind all the negative assessments of the impact of Brexit.

However, the key word in the last paragraph is “if”.  Like almost all economic theory, these models are static. They assume that the network of trade is fixed, and analyse the consequences of changing prices through tariffs.

The EU has become mired in regulation and the level of innovation is low. Outside the EU, the UK could alter the patterns of trade by innovating in, say, biotech or AI-related products and services. It is this dynamic response, and not the static one, which will determine whether or not Brexit is a success.

Economic models which claim to analyse the impact of Brexit are true – but only up to a point, Lord Copper, as the saying goes.

Until Scotland’s currency puzzle is solved, independence is economically delusional

Posted by on October 23, 2019 in Blog, Economy, Scotland | Comments Off on Until Scotland’s currency puzzle is solved, independence is economically delusional

Until Scotland’s currency puzzle is solved, independence is economically delusional

The possibility of Scottish independence is back on the political agenda once again. And one question – which currency would an independent Scotland use? – that was crucial in the 2014 referendum has still not been resolved.

The informal use of the pound is a very risky option.

To see why, the Scottish National Party (SNP) might look at the problems which Facebook is having in getting its proposed digital currency libra off the ground. Already, companies like PayPal, Visa, Mastercard and Ebay have withdrawn as potential sponsors.

While Facebook is a company and Scotland is a country, the issue is how the currencies are backed.

Facebook proposes to back the libra by its accumulated profits held in a portfolio of “low volatility assets”. But as Barry Eichengreen of the University of California points out, “anyone who lived through the 2008 global financial crisis will know that low volatility is more a state of mind than an intrinsic attribute of an asset”.

In the face of an unexpected adverse shock to the values of these assets, Eichengreen notes that these will be subject to the equivalent of a bank run. But there is no lender of last resort able to simply print money.

By simply using sterling, as many Latin American countries do with the US dollar, the Scots would have no means of printing money if their banks were attacked in a financial crisis. Taxes would have to rise massively to support the banks.

The Scots could instead apply to join the euro. An immediate problem with this would be the rule in the Stability and Growth pact that countries in the Eurozone should keep their budget deficits below three per cent of GDP.

The UK spends only 1.1 per cent of GDP more than it raises in taxes.  Ironically, this would make us a shoo-in for euro membership, if Britain as a whole wanted to join.

In contrast, the latest figures produced for Government Expenditure and Revenue for Scotland show the nation running a public sector deficit of seven per cent of GDP.

This is obviously much higher than would be allowed in terms of membership of the euro.  It is, in fact, the highest in the whole of Europe, the next highest being Cyprus at 4.8 per cent. So to join the euro, the Scots would have to make large cuts in public spending.

If instead they decided to set up their own currency, the markets would almost certainly force similar public spending reductions on them. After all, small countries running large public deficits tend not to be viewed kindly.

This problem has been magnified dramatically by the statement by Derek Mackay, the Scottish government finance secretary, that an SNP government in an independent Scotland would refuse to repay its share of outstanding UK debt.

A massive public sector deficit and defaulting on government debt is hardly a very sound basis on which to launch any new currency.

The desire for independence is often driven by emotion rather than rational calculation. But unless the currency question is addressed and solved, an independent Scotland would live to rue the day.

This year’s Nobel economics laureates have made the world a better place

Posted by on October 16, 2019 in Blog, Nobel Prize | Comments Off on This year’s Nobel economics laureates have made the world a better place

This year’s Nobel economics laureates have made the world a better place

This year’s Nobel Prize in economics, announced on Monday, was a ray of sunshine amid the prevailing media gloom.

The Prize was awarded for the work the new laureates had done on the alleviation of global poverty. This is one reason to be cheerful about it. Another is that Esther Duflo became only the second ever woman to win the prize, along with her close collaborators Abhijit Banerjee and Michael Kremer.

In addition, the winners have made important developments in how economists go about solving problems. These individuals are a key part of the drive to move economics on from an obsession with pure theory towards making it much more empirically-based.

At first sight, the award is very conventional. The laureates retain the basic view of economists: poor people are essentially rational agents, trying to take decisions which are in their own interests.

They may have much more difficulty in accessing relevant information than others, and face many more constraints on their ability to make the best decision. But they are just as rational as everyone else.

The similarity with tradition ends there. For the laureates’ main innovation is to introduce the use of randomised controlled trials (RCTs) into economics.

One hundred years ago, the British statistician Ronald Fisher was revolutionising the principles of statistical analysis. The maths that he developed enabled the testing of new medicines to become much more scientific.

The basic idea is to have a group of people who take the new drug and a group who do not.  The key thing is to assign them into the groups purely at random. This way, any difference in the outcomes of the group which was treated and the group which was not can reasonably be thought to be due to the impact of the drug.

Duflo and her colleagues, along with others they have inspired, have addressed a wide range of real-life policy problems in the developing world using the same approach, with hugely successful results.

Examples include discovering how best to get farmers to use more effective fertilisers, how to increase the uptake of safe water filters, how to improve patient safety in hospitals, how to spread advice most effectively about tuberculosis using community-based counsellors, and how to improve safety in public service vehicles.

The technique of RCT has even been applied in developed world settings. For example, experiments have been carried out with job applications, sending them out with names which strongly imply the ethnic background of the applicant and seeing if the response differs across groups. (It does.)

The approach of RCT is not without critics in economics, even now.  An important issue, for example, is that experiments are typically on a small scale, and there may be issues when they are scaled up.

But Duflo and colleagues, unlike some past economics laureates, have definitely helped to make the world a better place.

Forget ‘reparations’, scrapping subsidies is the way to help get Wales back on its feet

Posted by on October 10, 2019 in Behavioural Economics, Blog, Economy, Wales | Comments Off on Forget ‘reparations’, scrapping subsidies is the way to help get Wales back on its feet

Forget ‘reparations’, scrapping subsidies is the way to help get Wales back on its feet

Get ready to put your hands deep into your pockets for the boyos and girlos of the Welsh Valleys.  Adam Price, the leader of Plaid Cymru, called last week for the UK to pay “reparations” to Wales for the crime of reducing the country to poverty. For centuries, Wales has (apparently) been stripped of its natural resources and “deprived of its inheritance”.

Price’s demands are almost beyond parody. But they could become a frightening reality if a coalition government led by Jeremy Corbyn and various nationalist and green parties wins the next election.

The then-Labour leader of the Welsh Assembly, Carwyn Jones, set the new tone of Welsh whingeing the day after the Brexit vote in 2016.  “Wales,” he declared, “must not lose a penny of subsidy”. Wales, of course, had voted Leave.

There, in a sentence, was the economic policy of the Welsh government: hold out the begging bowl.

Wales is the poorest of the economic regions of the UK. Household income per head in 2017 – the latest date for which figures are available – was only £15,754, compared to the UK average of £19,514. The gap with the wealthiest regions is massive – the south east has an income per head 43 per cent higher, and London is no less than 77 per cent ahead.

It has not always been like this. In the early decades of the Industrial Revolution, the valley towns were probably the richest in the world.

Merthyr Tydfil, now a byword for poverty even by the standards of Wales, led the way. It was the first genuinely industrialised town in the history of humanity. In 1831, 96 per cent of its labour force worked in manufacturing and mining.

Many forces are at work in the story of Wales’ decline, but in modern times, it has often not exactly helped itself. The key to a successful economy is a skilled labour force, but in 2001, the Welsh government scrapped the publication of league tables for the performance of schools. This both deprived parents of information, and reduced the incentive for poor schools to improve.

The outcome was predictable. A Bristol University study estimated that it led to a fall of 1.92 GCSE grades per pupil. In 2015, the Welsh Assembly reversed the decision, but a lot of damage had been done to the human capital of Wales. For over a decade, students were less well educated than they could have been.

This lack of a skilled talent base inevitably holds back enterprise. This, along with other counter-productive decisions, may be why Wales is increasingly dependent on public sector jobs. Overall, Wales raises £14bn a year less in taxes than it spends on public services.

Might Wales be able to turn its fortunes around if it were forced to consider its economic decisions more carefully? After all, the policy of subsidising underperforming regions has been tried for decades. It has made no difference.

So instead of paying reparations, perhaps we should consider withdrawing subsides, as New Zealand did with great effect. By removing the handouts which are distorting Welsh decision-making and causing a vicious cycle of subsidy demands, we can give Wales the chance to restore the enterprise which used to flourish in the nation.

What kind of person crosses the Nevada desert to investigate UFO conspiracies?

Posted by on October 3, 2019 in Behavioural Economics, Blog, Economic Theory | Comments Off on What kind of person crosses the Nevada desert to investigate UFO conspiracies?

What kind of person crosses the Nevada desert to investigate UFO conspiracies?

Area 51 is a mysterious place.

Located deep in the Nevada desert, it is home to highly classified US military operations. Rumours abound that it harbours secrets about extraterrestrial life.

In June, a podcaster released an interview with someone who claims to have studied flying saucers in Area 51. The video spread like wildfire on the internet.

A proposal for an event took shape, labelled “Storm Area 51, They Can’t Stop All of US”. The idea was for large numbers to gather on 20 September in a couple of tiny Nevadan towns next to Area 51. The security defences would be overwhelmed. Citizens could then see for themselves the aliens being kept secret by the military-industrial complex.

Around two million individuals pledged on Facebook to attend. Estimates vary, but it seems that in reality only some 2,000 turned up in the nearby towns. Of these, a mere 200 or so actually arrived at the security fences which guard the area. No one tried to cut or climb over the barriers.

The event has subsequently attracted a great deal of ridicule in both the mainstream and social media. But it usefully illustrates two important principles in economic theory.

The first is the so-called free rider problem. It occurs when some individuals fail to contribute their fair share to the cost of a shared product or services.

An everyday example is that of a shared kitchen space in an office block. Provided enough people are willing to keep it clean, there is an incentive for others to free-ride and enjoy the clean kitchen without doing anything themselves.

The problem is that where free riders exist, the product or service in question tends to be under-produced. In the kitchen example, the supply of people willing to clean may drop off.

Exactly the same thing took place outside Area 51. Everyone wanted the razor wire fences to be cut, so they could consume the “product” of entering the site to see if it contained aliens. But not enough – in fact no one at all – was willing to cut the wire and incur the potential cost of being shot.

The event also illustrates the importance of revealed rather than stated preference.

Economists traditionally attach little weight to surveys in which people are asked hypothetical questions about what they might do or pay in different situations. These constitute stated preferences.

Instead, economists prefer to infer preferences from the actions people actually take. If you always buy Pepsi rather than Coke, you have revealed your preference between the two.

Pressing a button to say you “like” something merely states your preferences.  The cost of doing this is virtually zero. Revealing preferences may involve substantial costs, such as travelling to the Nevada desert.

This fundamental point is being lost in many of the reactions of decision-makers to events on social media. Far too much importance is being attached to actions which are almost costless.

The UFO buffs of Area 51 have done a public service by providing a clear example of this principle, and of evidence that “likes” do not necessarily equal action.

In such volatile times, the safest assets aren’t necessarily what investors think

Posted by on September 26, 2019 in Blog, Markets | Comments Off on In such volatile times, the safest assets aren’t necessarily what investors think

In such volatile times, the safest assets aren’t necessarily what investors think

Given the climate of intense uncertainty, the FTSE index remains remarkably resilient.

It currently sits almost bang in the middle of the 7,000-7,600 range, where it has been since the beginning of January 2017.

Brexit does not seem to trouble share prices. Nor do the threats by John McDonnell, Labour’s shadow chancellor, to carry out extensive raids on shares and put workers on the boards of companies.

These risks and uncertainties are “priced in” by the market. The concept of market efficiency, revered by economists, means that all available information is taken into account in the process of setting share prices. The implication is that pension funds and traders alike appear to attach only a small probability to a disruptive Brexit or to Labour forming a government.

Of course, it is precisely when an unexpected disruptive event takes place that the market ceases to be efficient. Market participants need time to absorb and process the implications of the new environment, and do so at different speeds. There is widespread disagreement about what the “rational” price of an asset is, and as a result volatility abounds.

So despite the sanguine way in which the market is currently behaving, there must be many investors in shares of various kinds who are casting anxious eyes back over their shoulders.

They can take comfort from an article published in the latest Quarterly Journal of Economics by Oscar Jorda, of the University of California, and colleagues. Its findings represent an important addition to scientific knowledge.

The authors publish estimates of the annual total returns on equities, housing, long-term government bonds and short-term fixed interest government securities (three-month Treasury bills in the UK). The impressive nature of the work is not simply that it covers 16 advanced economies. Data is provided for every year between 1870 and 2015.

Government debt in countries like the US and the UK is considered a “safe” asset. But one of the most remarkable findings of the research is that the real return (in other words gains after allowing for inflation) on such assets has been very volatile, often even more so than the supposedly “risky” assets such as equities.

This is quite contrary to the conventional view of how the world is supposed to work. If one asset gives a higher return than another, the expectation is that its price is more volatile. There is a trade-off between risk and return. But this seems not to be the case in reality.

Intriguingly, both equities and residential real estate have yielded total real gains of no less than seven per cent a year. Housing outperformed shares from 1870 until the Second World War, and the position has been reversed since then.

Governments come and go, as indeed have two major world wars. But over the course of well over a century, holding equities and not worrying about short-term fluctuations has yielded rich rewards.

Obviously, the past is not necessarily a guide to the future – but the past here spans evidence from nearly 150 years. Something to think about if you’re looking to invest at a time of such global political uncertainty.

Britain’s car industry could weather a storm of tariffs better than you’d think

Posted by on September 19, 2019 in American Economy, Blog, Industry | Comments Off on Britain’s car industry could weather a storm of tariffs better than you’d think

Britain’s car industry could weather a storm of tariffs better than you’d think

The latest American Economic Review contains a timely paper. Keith Head and Thierry Mayer, at the University of British Columbia and the Banque de France respectively, estimate the consequences of changes in tariff and non-tariff barriers to the car industry.

They look at both US-led protectionism and Brexit, and calculate how these might change the location of production.

The car industry is of course the tradeable industry par excellence. For example, 50 per cent of cars sold in OECD markets are assembled in locations that are neither the headquarter nor the consuming country.

The United States had threatened to impose so-called Section 232 tariffs of 25 per cent on cars imported from Canada and Mexico on national security grounds. And President Trump did bring in such tariffs in aluminium and steel, although in the summer America reached separate bi-lateral agreements with Canada and Mexico.

Head and Mayer estimate that Section 232 tariffs would have devastated the Canadian and Mexican car industries. Even if the two countries retaliated, car production would have fallen 40 per cent in Mexico and 67 per cent in Canada.

A key reason for these massive numbers is that almost all the brands made in Canada (11 of 12) and Mexico (10 of 14) are also made in the US. Under tariffs, there would be a strong incentive to shift production to America.

The results for the Brexit scenario are quite different.

The simulation is of a hard Brexit. UK exports face the European Union’s 10 per cent Most Favoured Nation tariffs, and Britain reciprocates at the same rates. The authors assume that we cannot roll-over existing EU agreements with third-party nations, and that the tariff structure with them reverts to the same basis.

The EU runs a large trade surplus with the UK in cars, so higher tariffs mean that we have less to lose. The British car industry actually gains through the protective effect of tariffs.

Overall, Head and Mayer estimate a fall in production of only four per cent. This arises purely from their calculations of trade with countries such as Turkey and South Korea.

The paper is impressive in its detail and in the rigour of its analysis. These are the great strengths of much modern economics.

Of course, it also has its weaknesses. The analysis is, to use a jargon phrase, a purely static one: it takes the technology and the structure of production as given, and traces how tariffs, by changing costs and so the incentives of firms to produce in different locations, work through the industry.

It does not take into account any dynamic changes: how productivity or innovation (which alter the structure of production) might respond to changed circumstances.

Assessing these factors is a much harder task. Most would agree, for example, that a hard Brexit under Jeremy Corbyn would lead to ossification, although this is a matter of judgement and not analysis.

Still, despite these limitations, the study shows that the impact on production of a hard Brexit even in an industry which thrives on trade would be negligible. It makes interesting reading at a time when hysteria over a no-deal Brexit is once again reaching a fever pitch.

Watch out fiscal conservatives – the mood has shifted and the spending taps are on

Posted by on September 12, 2019 in Blog, Government Spending | Comments Off on Watch out fiscal conservatives – the mood has shifted and the spending taps are on

Watch out fiscal conservatives – the mood has shifted and the spending taps are on

The Autumn Spending Review announced by the chancellor Sajid Javid barely raised a ripple last week.

Yet the increase planned in 2020/21 for what the Treasury calls “day-to-day departmental spending” is the highest for 15 years, no less than 4.1 per cent in real terms.

This spending pays the running costs of public services, the main component of course being public sector wages. An increase of this size ought to mean better services, although the Gordon Brown years demonstrated quite clearly that more spending need not mean an improved service.

This number only represents 37 per cent of total public spending. Considerably more is spent on welfare benefits, pensions, and interest on the national debt. The squeeze is still on here, so the overall rise in total current public spending is more modest, at just 2.0 per cent after allowing for inflation.

Nevertheless, Javid’s plan does represent a step up in the move away from austerity envisaged by the former chancellor Philip Hammond in last year’s autumn Spending Review.

Still, this pales in comparison to what is envisaged for the public finances under the current Republican administration in the US. The Congressional Budget Office (CBO) there notes that the federal budget deficit for 2019 will be $960bn. Budget deficits are projected to average $1.2 trillion a year between 2020 and 2029.

The CBO calculates that this will push up federal government debt to 95 per cent of GDP, the highest level since the late 1940s.

On both sides of the Atlantic, the move away from austerity represents a major shift in the narrative around public sector debt. It is now, it seems, okay to feel relaxed about government borrowing.

The mood in mainstream academic macroeconomics has also shifted. Ken Rogoff, a former chief economist at the IMF, said in 2010 that a debt-to-GDP ratio above 90 per cent risked a substantial reduction in the long-term growth rate (a view shared by many in developed countries), triggering a wave of austerity.

Yet in February this year, he changed his tune, saying that the steady decline in global real interest rates meant that the debt-to-GDP ratio was no longer a concern.

Olivier Blanchard, another former IMF chief economist, made a similar point earlier this year, when he argued that, as the real rate of interest is lower than the real growth rate, future interest payments on debt could be met out of the proceeds of growth.

While this is not necessarily unusual (such a state of affairs has been the case often enough in the last 150 years), the argument that governments should use it as an excuse to build up debt very definitely is.

The shift in attitude has implications in politics, too. For years, right-wing parties have painted the left as being as being spendthrift and irresponsible.

With an election seemingly inevitable in the UK, it will be interesting to see whether the Conservatives – having turned on the taps – can make that narrative stick to Jeremy Corbyn.
