Three years on

It is now three years since the British electorate narrowly voted in favour of leaving the EU, and despite the best efforts of the government the UK remains an EU member. The longer the saga drags on, the more vociferous are the Brexiteers who believe they are being denied the victory that is rightfully theirs. When David Cameron first mooted the idea of a referendum, it was to lance the boil of Euroscepticism within the Conservative Party. This strategy could not have been less successful if he had tried. Britain remains more polarised than at any time in living memory and Brexit has consumed politicians to such a degree that they have no time for anything else. Historians argue that the 1956 Suez Crisis was a defining moment in British post-war history, yet three years after the event the scars were at least beginning to heal. Not so with Brexit. 

There has been a lot of revisionism over the past three years, with Brexit supporting politicians making the case that people knew what they were voting for and that “the will of the people” must be respected. The argument is simple and convincing – and profoundly wrong. In the modern argot, Brexiteers are engaging in heavy “gaslighting.” Admittedly David Cameron did point out prior to the referendum that a vote for Brexit would be “to leave the EU and leave the single market. We’d then have to negotiate a trade deal from outside with the European Union.” But Brexit supporters reassured the electorate that the UK would retain access to the single market (“absolutely nobody is talking about threatening our place in the single market”) and the customs union was barely even mentioned. For anyone who doubts my take on events, look at analysis conducted by the charity Full Fact.

The pamphlet sent to all households ahead of the referendum certainly did not suggest that leaving the EU would mean leaving the single market let alone the customs union. Instead, it pointed out that “Voting to leave the EU would create years of uncertainty and potential economic disruption … Some argue that we could strike a good deal quickly with the EU because they want to keep access to our market. But the Government’s judgement is that it would be much harder than that” (here is a link to the pamphlet if you want to check for yourself).

Whatever Remainers and Leavers may disagree about, it is indisputably the case that the difficulties inherent in leaving the EU were clearly pointed out prior to the referendum. The events of the past three years have borne out this assessment and it is the issue of leaving the EU on terms that would not crash the economy that has always been at the centre of my disagreement with those who wish to leave at any price. Millionaires like Jacob Rees-Mogg or Boris Johnson may be able to survive the hit in the event of a no-deal Brexit but it will be a lot harder for those far lower down the income scale. And for all the fact that the apparent foot-dragging has been blamed on the Remainers in government who have tried their best to thwart the project, the simple truth is that MPs do have a duty to look out for the interests of their constituents, and these will not be served by a no-deal Brexit. 

Who will drive the car towards the cliff edge? 

The next four months will be critical in this regard. It is has long been assumed that Boris Johnson is a near-certainty to be chosen as the next Tory party leader (his recent domestic issues notwithstanding). However, the bookmakers put him at 1-6 odds-on compared to 1-16 on Friday, whilst the odds against his challenger Jeremy Hunt have narrowed from 12-1 to 4-1. Neither candidate fills me with any confidence. 

Johnson maintains that the EU would not have to levy tariffs on UK imports in the event of a no-deal Brexit because the UK could rely on Article 24 of GATT. This is untrue. Article 24 only applies if an agreement has been reached, not if it has been decided not to have an agreement or the two parties are unable to come to an agreement. If the EU were to drop tariffs against the UK in the event of no-deal, it would have to do so against all other countries under the WTO’s Most Favoured Nation rules and that is not going to happen. Meanwhile Jeremy Hunt said at a Tory leadership hustings event yesterday that he had “visited an amazing company … that employs about 350 people; their margins are around 4%. A 10% tariff would wipe them out. So there would be an economic impact of no-deal. If that was the only way to deliver Brexit then I’m afraid we have to do that because that’s what people have voted for. We are a democracy first and foremost.” Yes folks, you read that right. The party of business is prepared to throw small businesses under the bus to deliver Brexit (check the link).

But assuming Johnson does get the gig, he will have a lot of hard work to do. He will come into office on the back of a track record of disloyalty during Theresa May’s tenure and a reputation as one of the worst foreign secretaries ever to grace the post. He is widely distrusted at home based on his famously loose relationship with the truth, and is even less respected across Europe where he is regarded as the face of Brexit. Johnson has insisted that the UK should leave the EU on 31 October: If he holds to that pledge, it will be without any new deal with the EU which has said it will not reopen negotiations, and certainly not with him. But parliament has already expressed its opposition to a no-deal Brexit so if he pushes ahead with this option MPs are unlikely to work with him on other issues (remember the Conservatives form a minority government), which raises the prospect of a general election.

One option that should not be ruled out is that Johnson may be forced to put the Brexit question back to the electorate at some point when it becomes clear that the EU is not prepared to negotiate and the alternative is a hard Brexit. For one thing, it would spike the Labour Party’s attempts to put a second referendum on the table, and if the Conservatives stand for anything it is to keep Jeremy Corbyn out of 10 Downing Street. Nor is Johnson a Brexit ideologue, like many on the lunatic fringe of his party, and he far more ideologically flexible than Theresa May. If any politician can sell the idea of a second referendum, it is him.

Whilst I would attach only a small probability to this outcome, it is evident that as we head into a fourth year of political impasse, something has got to give. Let us also not forget that the EU has been remarkably tolerant of the UK’s position so far. We can debate whether the EU’s stance is right but it has always been open to discussion. That might change in future as senior positions at the European Commission come up for grabs. Jean-Claude Juncker and Donald Tusk are about to ride off into the sunset and their successors may wish to move the EU debate forward rather than having to be tied up by Brexit. We know that President Macron is opposed to a further Brexit extension, and he is unlikely to grant Johnson any favours.

A year ago, I refrained from offering any predictions as to where we would be in the Brexit debate in June 2019, largely because I suspected that an Article 50 extension would preserve the status quo. I do not want to offer any hostages to fortune this time either. But I do not think we will be in the same waiting room in 12 months’ time. In order to properly confront the issue, the next prime minister will have to either risk crashing the economy or going where Theresa May did not dare, by offering a referendum or in an extreme case withdrawing the Article 50 notice. The time for talking is over. We need to move on.

Strike whilst the fiscal iron is hot

Apart from a brief splurge in the immediate aftermath of the financial crisis, western governments have generally adopted a tight fiscal stance over the past decade with the result that it has been left to central banks to do nearly all of the policy easing. In my last post, I noted that we have broadly reached the limit of what monetary policy can be expected to achieve and that during the next cyclical downturn fiscal policy will have to play a much bigger role. This raises two questions: (i) how much impact will fiscal easing have and (ii) how much fiscal room do governments have?

With regard to the first issue, the now accepted wisdom is that fiscal multipliers are higher than expected prior to the last recession. Much of the evidence available prior to the Great Recession suggested that fiscal multipliers in the developed world were significantly less than unity. In other words, a one percentage point fiscal injection produced a long-run increase in output of less than 1%. If that is indeed the case, the economy would be relatively unresponsive to a fiscal injection and the resultant increase in debt could be judged to be too costly.

But four years after the crash, the IMF concluded that it had underestimated fiscal multipliers by between 0.4 and 1.2. On the assumption that the pre-recession average was around 0.5, the updated research suggests that the true multipliers are in the range 0.9 to 1.7 which is a whole different ball game. Furthermore, they concluded that the efficacy of fiscal policy is greater when interest rates are at the lower bound, as they have been for the past decade but which was never seriously considered prior to 2008 as it was not an outcome that many people foresaw. However, on the basis of the latest empirical evidence it appears that a fiscal expansion will deliver a decent bang for the buck.

But can governments afford to expand fiscal policy when government debt levels are already very high? Obviously, the current position in which public debt levels across Europe average more than 80% of GDP is not a great place to start. But an environment in which interest rates remain low has created a significant degree of fiscal space for governments. The concept of fiscal space is defined as how much governments can borrow without losing market access or facing sustainability challenges. Conventional economic wisdom suggests that markets will limit their purchases of sovereign debt if it is rising at a rapid pace, and require compensation in the form of higher yields. Higher yields raise the cost of debt servicing and increase outlays on interest income which, if they cannot be offset by spending cuts in other areas, result in higher deficits and debt. There is thus a dynamic link between interest rates and debt. But in today’s environment interest rates are lower for any given level of debt than we might have thought possible in the past, hence the idea that fiscal space has increased.

The well-known solvency conditions for public debt depend on the primary deficit (i.e. excluding debt servicing costs), the rate of nominal GDP growth and the interest rate on debt (see chart). The higher the deficit or interest rates the greater the upward pressure on debt-to-GDP ratios, whilst the faster is GDP growth the more downward pressure there is. Getting the balance of these factors right is an important consideration in fiscal solvency, as it suggests it is possible to run a public deficit and still broadly keep the debt ratio stable, depending on the extent to which GDP growth exceeds the interest rate.

This growth/interest rate nexus thus becomes crucial. To look at this in a long-term context I have taken data for the UK going back to 1700. During the 18^th and 19^th centuries on average, the interest rate on debt was higher than the rate of GDP growth. Even though the UK did run a primary surplus over the period, the debt ratio continued to creep upwards from around 20% of GDP in 1700 to 200% by the end of Napoleonic Wars and only fell back below 100% in 1861. On average during the 19^th century the debt ratio averaged 120%. But although the UK ran a primary deficit on average during the 20th century, the rate of GDP growth exceeded the interest rate with the result that the debt ratio tended to fall. Even though the debt ratio hit almost 250% in the wake of the Second World War, a combination of solid growth and financial repression which put a lid on interest rates, was sufficient to produce a significant reduction in the debt ratio to just above 20% by the early-1990s.

The takeaway is that high debt levels need not be the obstacle to fiscal expansion that many politicians seem to think. Admittedly, GDP growth has slowed over the last decade compared to what we were used to prior to 2008, but even if trend real growth is in the range 1% to 1.5% and inflation remains stuck at 1.5%, this implies nominal GDP growth of around 2.5% to 3%. Meanwhile central banks are currently engaged in a policy of financial repression (though they would never call it as such). Right now, 10-year yields in the UK are just above 0.8% and in Germany they are well into negative territory at -0.3%. Clearly, therefore, nominal GDP growth is higher than the interest rate on debt and a quick calculation allows us to estimate the size of the primary deficit that will allow the debt-to-GDP ratio to remain stable[1]. Current figures for the UK, for example, suggest that a deficit of 1.9% is eminently sustainable. 

To those politicians who argue that reducing the debt ratio is an objective of itself, I pose the question why? The demand for long-term government paper has never been higher as investors who are flush with the liquidity created by central banks fall over themselves to find a place to invest it. This is not to say that governments should be opening the taps with no regard for the future. After all, if rates do rise the cost of servicing high debt levels will also increase. But there is scope for a judicious loosening of the reins, and there has never been a better time to use the opportunity afforded by low interest rates for social purposes. Those European governments who are passing up this opportunity (and not just those in the euro zone) are guilty of sloppy economic analysis, and perhaps even more egregiously, impoverishing their citizens for no good reason. Fiscal opportunities like this have historically not come around often.

The limits of central banking

Prior to the great crash of 2008, investment bankers were – at least in their own minds – regarded as masters of the universe. No more. As their fancy clothes, woven from cloth so fine that the eye could not see it, were revealed to be non-existent, they were usurped by central bankers who used the muscle of zero interest rates and the power of their balance sheets to rescue the global economy from meltdown. More than a decade later and questions are increasingly being raised as to whether the tools which were deployed in 2009, and which are still in use today, are fit for purpose. Worse still, central bankers can be forgiven for wondering whether they have been hung out to dry by politicians who seem increasingly unwilling to provide the necessary degree of support to allow them to do their job effectively.

The BoE: A relative oasis of calm

The BoE finds itself in a slightly easier position than either the Fed or ECB although it has been sucked into the political fallout from Brexit, and with a new Governor set to take over from Mark Carney in just over seven months’ time, his successor may face an unenviable task in steering a post-Brexit course. One criticism that can be levelled at the BoE is that its forward guidance policy, which has often hinted at rate hikes which never materialise, may be about to miss the mark again. Indeed, recent hints that the next rate move will be upwards flies in the face of economic data, which point at below-target inflation in H2, and trends in the global monetary cycle. In common with many central banks, it has failed to create space to ease policy in the event that the economy cools. Central bankers dismissed this line of reasoning when conditions were propitious for a rate hike in 2014, and whilst Brexit has complicated the picture, it is hard to avoid the feeling that the BoE will go into the next economic slowdown with precious little ammunition.

The ECB: Taking flak from all sides

Across the channel, the ECB’s situation is even more desperate. Despite having cut the main refinancing rate to zero and the deposit rate to -0.4% whilst boosting its balance sheet to almost 40% of GDP, a meaningful economic recovery in the euro zone remains elusive and inflation continues to undershoot the ECB’s target. There are now expectations that the ECB will counter current economic conditions with even more monetary easing – a view that Mario Draghi reinforced this morning. The ECB is all that has stood between the integrity of the euro zone and disaster: It has done all the policy easing whilst governments have stood idly by without deploying any of the fiscal ammunition at their disposal. Draghi, who will leave his post as ECB President in October, deserves great credit for doing “whatever it takes” to keep the show on the road. Those who have criticised Draghi, including Bundesbank President Weidmann and various northern European politicians, should take some time to reflect on what might have happened in 2012 had the ECB not opened the taps.

However, the criticisms levelled by Weidmann at least come from someone with skin in the game. Draghi’s hints of further easing were met today by a Twitter blast from the self-styled stable genius in the White House accusing the ECB of weakening the euro against the dollar “making it unfairly easier for them to compete against the USA. They have been getting away with this for years, along with China and others.” This sends two messages: (i) Trump is a lobster short of a clambake and more seriously (ii) he threatens to open a new front in the war of economic nationalism, dragging the euro zone into a conflict which has hitherto been confined to the US and China.

The Fed: Managing in the presence of a stable genius

Imagine, therefore, what it must be like to be in Jay Powell’s shoes. The Fed has done what the textbooks recommend by taking away some of the excessive stimulus as the economy recovered. Unfortunately, Trump has determined that the Fed is the main obstacle to the ongoing US upswing and has been excoriating the FOMC for not cutting rates. Worse still, a story surfaced today suggesting that in February the White House explored the possibility of stripping Powell of his chairmanship and leaving him as a Fed governor. This is an unprecedented attack on the independence of the central bank. Not that politicians have refrained from dictating to the Fed in the past. One story, recounted by Reuters journalist Andy Bruce, recalls instructions from the White House to former Fed Chairman Paul Volcker ordering him not to raise interest rates during an election campaign. “Volcker, knowing the command was illegal, left the room without saying anything.” But the attacks on Powell are far worse – and lest we forget, he was appointed by Trump in 2018 with the endorsement that “He’s strong, he’s committed, he’s smart.”

The FOMC has recently revised down its assessment of the need for future rate hikes and it is increasingly likely that the next move will be a cut. It is not clear whether this is a direct response to the President’s attacks or whether the Fed has misread the economic outlook so badly that it feels the need to ease policy rather than tighten, as it believed necessary at the start of the year. However, to the extent that the Fed may be trying to head off further attempts by Trump to impose his own candidates on the FOMC, following the failed attempts to appoint Stephen Moore and Herman Cain, it is likely that the Fed is acceding to the pressure. Perhaps the Fed’s view is that by throwing a few small scraps in Trump’s direction, it will be better placed to maintain its independence in the longer run. But whilst it has long been evident that the Fed is not as free from political influence as it portrays, selling out in such an obvious manner could have the reverse effect by undermining its perception of independence in the market.

Dealing with the lower bound

The common themes across the central banking universe are that they are running out of tools to deal with the low-inflation world which we inhabit today, whilst also coming under much greater pressure to deliver on politicians’ objectives. With regard to instruments at the central banks’ disposal once interest rates reach the lower bound, there are essentially just three: QE, forward guidance and driving interest rates into negative territory as the ECB has done. At a recent Fed monetary policy conference (a so-called “Fed Listens Event” which deserves more in-depth coverage another time), a paper by Sims and Wu highlighted that QE is the most useful tool of the three; forward guidance depends on a central bank’s credibility (cf. the Fed’s position) and that negative rates become less effective the larger is the balance sheet (cf. the ECB’s position).

With central banks having tried all of these instruments to a greater or lesser degree, it is difficult to avoid the conclusion that we are near the end of the road with regard to monetary policy. After all, central banks have largely failed to stimulate inflation and there are serious concerns that if the floodgates are opened even further, this will serve only to store up greater problems in the future. Indeed, I have long argued that we will only know the full impact of low interest rates in the very long term once we see what our pensions are worth. What this does suggest is that much more of the burden of managing the economy will have to fall on fiscal policy in future – an issue I will deal with in my next post. The good news is that this will at least take central bankers out of the firing line and make politicians take some responsibility for what they should have been doing all along.

Not the end of history

It is thirty years since Francis Fukuyama’s essay “The End of History?” was published in the magazine The National Interest. It was subsequently fleshed out into a book which elevated Fukuyama to the first rank of commentators on global geopolitical issues. Viewed from the perspective of three decades later, it is an idea that has not aged well. Fukuyama’s thesis was that liberal democracy had achieved such dominance as a form of government around the world that we had reached “the end point of mankind's ideological evolution and the universalization of Western liberal democracy as the final form of human government.” This was pretentious hubris in 1989. Today, the argument just looks crass.

There is no doubt that the argument has been hugely influential amongst western leaders. The likes of Bill Clinton and Tony Blair went to great lengths to use foreign policy as a tool to promote western values. The “end of history” mind-set also underpinned the development of the EU. Following the fall of the Iron Curtain, the European Economic Community – whose aim was to promote economic integration amongst its 12 member states – opted to ratify the Maastricht Treaty to create the European Union thus marking a further step on the road to creating an “ever closer union” between the peoples of Europe. It also facilitated an eastward expansion to incorporate 16 new members, many of which had little recent experience of the forms of government practiced in the west. Expansion was based on the idea that membership is open to "any European State which respects the values referred to in Article 2 and is committed to promoting them." Those Article 2 values are "respect for human dignity, freedom, democracy, equality, the rule of law and respect for human rights, including the rights of persons belonging to minorities." Very Fukuyama-esque.

All seemed to be proceeding on track until the crash of 2008. Unfortunately, governments over-promised and under-delivered on what they were able to do to stimulate a lasting economic recovery following the great recession, thus paving the way for populists to make political headway and helping to undermine Fukuyama’s ideas. But it is the rise of China that has had a bigger impact on the post-1989 hubris. China can in no way be defined as a liberal democracy, yet the performance of its economy has been the most significant economic event since the dawn of the industrial revolution in the eighteenth century. It would be a major stretch to assume that the majority of Chinese would be prepared to swap their system of government for the rapid rise in living standards experienced over the past three decades. An even more extreme example is Russia where moves towards a more democratic system of government coincided with a period of hardship which tilted the scales back towards authoritarianism.

Fukuyama supporters would no doubt point out that there is a distinction between “history” and ”events” where the former represents an overall narrative and the latter are the individual occurrences which go up to make the whole picture. But this is to overlook the fact that events can have a significant impact on the overall course of history. Fukuyama’s thesis rests on the notion that even if we deviate from the path of liberal democracy, it will eventually reassert itself in the long run, but this is not particularly helpful if we end up in a prolonged period of deviation from the “ideal” – as those who lived through the period 1914 to 1945 might testify.

Fast forward to the present day and the takeaway is that those who dismiss concerns regarding the behaviour of Donald Trump or the fragmentation of European politics as a short-term problem may be missing the point. Trump clearly has no interest in finding an accommodation with China on trade issues and indeed has ratcheted up the pressure in recent months. Tempting though it is to put this down to posturing ahead of the 2020 election, it would be naïve in the extreme to expect him to change his position in his second term as President (assuming he is re-elected). Rules-based liberal democracy is not part of Trump’s makeup and even if he does prove to be an aberration from the US presidential norm, he could do sufficient damage to Sino-US relations in the interim that ends up inflicting significant long-term damage on the US and undermining the cause of liberal democracy on both sides of the Pacific.

In a similar vein, those expecting the current shenanigans over Brexit to be resolved easily and quickly will also be disappointed. The idea that “something will turn up” is a Micawberish way of thinking that does not do justice to the magnitude of the problem. Too many politicians have signed up to the Fukuyama view that politics will quickly tend towards the liberal democratic norm. But the grand sweep of history suggests that societies are often plunged into chaos by sudden and unexpected events which overwhelm the system’s capacity to respond and a long period of adjustment then ensues. In the case of Brexit, politicians cannot hide behind the excuse that a no-deal Brexit is unexpected. Indeed, many of them have advocated it. But a generation of politicians that has grown up without bad things happening because something always turns up may be pushing their (and our) luck too far.

In my view, Fukuyama’s assertion of an end of history makes the mistake of assuming history as some form of linear progression. Perhaps it should be thought of as a 3D spiral, in which we appear to be making progress in one dimension whilst going over the same old ground in another (see chart). Or as Mark Twain (allegedly) said, “history doesn’t repeat itself but it often rhymes” which is why we should wake up to the damage that Trump or a no-deal Brexit might cause rather than assume it will quickly pass.

Is that a B'Stard I see before me?

A crowded field but where is the quality?

They say that fact is stranger than fiction and nowhere is this more true than in British politics right now. Thirty years ago, the TV scriptwriters Laurence Marks and Maurice Gran satirised the Conservative Party of the 1980s in the TV sitcom The New Statesman. It was based around the fictional hard-right Tory MP, Alan B’Stard, who was portrayed as an unscrupulous, amoral individual who would stop at nothing to fulfil his ambitions. It is difficult to watch this clip and avoid the impression that many of the current candidates for the Tory leadership are aping B’Stard’s fictional rhetoric.

Nominations for the Conservative Party leadership closed today, with 10 candidates on the ballot paper and with the first round of voting due to take place on Thursday. Just as a reminder of what is at stake, 314 Tory MPs are due to choose two candidates to succeed Theresa May who will then face a ballot of all Party members. What this means is that 124,000 people will choose the person who will attempt to negotiate the UK’s departure from the EU. Or, to put it another way, this choice will be made by 0.27% of the total electorate. Moreover, if only one candidate emerges from the parliamentary process, as happened in 2016, the new PM will be chose by less than 0.01% of all eligible voters[1]. To highlight the New Statesman-like surrealism of the debate, three of the candidates (Rory Stewart, Andrea Leadsom and Michael Gove) have all admitted to past drugs misdemeanours. Two of the hardline Brexiteer candidates (Dominic Raab and Esther McVey) have suggested suspending parliament to ensure that it cannot block Brexit on 31 October. And this is before we get to Boris Johnson whose strained relationship with the truth is legendary. Welcome to democracy in 21st century Britain.

Reviewing the fiscal options

But for all the lack of quality on display to inherit the office held by substantial politicians such as Winston Churchill and Margaret Thatcher, the economic issue of interest concerns the fiscal policy options suggested by the candidates. Let’s start with Boris Johnson. He has already threatened to withhold the £39 billion payment for incurred liabilities unless the EU gives the UK better exit terms. But assuming this is paid over a period of 3 years, it only amounts to around 10% of the EU’s annual budget revenues (or 0.1% of EU GDP). Not only is it a trifling sum in the grand scheme of things but lawyers suggest that such a move is probably illegal. It would also be the first time since the UK came into existence following the Act of Union in 1707 that it has defaulted on its credit obligations. The EU simply will not be threatened in this way and it would cost the UK far more than it gains. Whilst such a policy may play well with the Tory faithful, it would be an act of monumental economic stupidity.

Various leadership candidates have also promised tax cuts in the event they accede to 10 Downing Street. Johnson has promised to raise the threshold for the higher rate of income tax (40%) from a starting salary of £50,000 to £80,000, at an estimated cost of £10 bn (around 0.5% of GDP). Johnson claims that this can be funded from the £26.6 bn set aside by the Treasury as an insurance fund against a no-deal Brexit. But since Johnson has threatened that the UK would be prepared to walk away from the EU without a deal, he is surely going to need the emergency fund. Johnson’s team counter that the policy would be part funded by raising the upper limit on national insurance contributions. However, the Institute for Fiscal Studies has pointed out that this would benefit richer pensioners who do not pay NICs – which, oddly enough, maps onto the Conservative Party membership demographic.

Meanwhile, Brexiteer Dominic Raab has suggested reducing the basic rate of income tax by 5 percentage points over a period of five years. A rough rule of thumb based on Treasury calculations suggests that this will reduce revenues by more than 1% of GDP on a five-year horizon with no suggestion of how this will be funded. Foreign Secretary Jeremy Hunt, who is also in the running, has called for a huge increase in defence spending to “support our great ally, the United States.” Currently, the UK spends around 2% of GDP on defence – each one percentage point increase will raise outlays by £20 bn. Maybe former Health Secretary Hunt thinks he can find more for defence by taking something away from the health budget or perhaps in contrast to his rivals, he believes taxes should be raised. But like his rivals, he has failed to set out how his plans will be funded.

We should also not forget Michael Gove’s plan to abolish VAT and replace it with a lower, simpler sales tax. Interesting theory but a bad policy. For one thing, it is one of the government’s biggest revenue generators, delivering £138 bn per year to the Exchequer (6.3% of GDP). Moreover it is a general tax involving the production and distribution of goods and the provision of services, and whilst it is borne by the final consumer it is more than simply a sales tax. VAT is also efficient, in contrast to Purchase Tax which it replaced and which was levied on a range of goods at differing rates. It was certainly not efficient. If Gove’s proposed tax is “simple” it will have to be applied to a wide range of goods in order to generate the kind of revenue that VAT does currently, which raises questions of whether items such as food will remain exempt.

Then there is the question of how it impacts on the supply chain. If it is levied at every stage of the process, a “simple” 5% rate on a chain with five links results in a 27% tax rate compared to the current VAT rate of 20%. Moreover, if an exporter is the final link in the chain they will not be able to recoup the tax paid without raising their international selling price, which would render their product uncompetitive. In short, switching away from VAT would involve far more complexity than Gove believes. A simpler tax which is revenue neutral would require a lot of thought and would almost certainly prove impossible to implement before the next election. There is a reason why 166 of 213 UN members have adopted VAT and why India has just rolled it out. It is simple and more efficient than the alternatives.

The fact that the Tory front-runners have made taxation such a big part of their leadership bids reflects the lack of new ideas coming from the political right. Reducing direct taxes worked in the 1980s because previous levels of tax were too high so there were some incentive effects derived from cuts. In addition, there was a large rise in female labour force participation which helped swell income tax coffers. However, the UK did not face the problem of an ageing society which it does today. As a consequence the UK does not have the same scope to cut taxes without major consequences for future public liabilities. Having endured nine years of austerity to bring public finances back into line, it would be fiscally irresponsible to waste all the hard work on unfunded tax cuts which benefit particular interest groups simply to win the race for Number 10.
