GALLERY GUIDO: Osborne, the Laffer Curve and the Left

There’s a Computable General Equilibrium Model at the Treasury. If it were made of string and resin it wouldn’t be any less reliable, but its predictions about the cut in corporation tax are likable, so let’s quote them.

The Treasury select committee told us the computer is forecasting corporation tax going from 28 pence to 20 pence will increase GDP between 0.6 and 0.8 per cent, and will increase business investment from 2.5 per cent of some damn thing or other to 4.5 per cent.

It’s “a quiet revolution” George Osborne says, of this example of the Laffer Curve in action.

This curve is still mocked by the left. But it has an interesting pedigree.

An early exposition from the 1930s put it like this:

“Nor should the argument seem strange that taxation may be so high as to defeat its object, and that, given sufficient time to gather the fruits, a reduction of taxation will run a better chance than an increase of balancing the budget.”

That is – the budget can be balanced by reducing tax not increasing it.

“For to take the opposite view today is to resemble a manufacturer who, running at a loss, decides to raise his price, and when his declining sales increase the loss, wrapping himself in the rectitude of plain arithmetic, decides that prudence requires him to raise the price still more—and who, when at last his account is balanced with nought on both sides, is still found righteously declaring that it would have been the act of a gambler to reduce the price when you were already making a loss.”

“The act of a gambler” to reduce taxation. “A dangerous experiment” as it might be said. An ideological leap into the dark. These criticisms are still made by the left, and even by Red and Redder Eds.

The author of the proposition was one of the few economists capable of writing a phrase like “the rectitude of plain arithmetic”. But then he wasn’t an economist from birth.

It was John Maynard Keynes.

      The real question is where on the Laffer curve is the sweet spot. Too far one way and you lose revenue from too high taxes. Too far the other way and you lose revenue from too low taxes. This is why it is curve and not a straight line. So where is the sweet spot? Maybe we should ask the Danish Prime Minister for another selfie.

          • The new Messiah says:

            Using the example above, where manufacturers ask a higher price when their goods are not selling, this is just as stupid as selling the goods at far too low a price so you never make any money. Clearly there is obviously a point at which if your taxes are too low they do not bring in enough revenue to pay for things like law and order, defence, health, pensions, education, etc that we all take for granted.

          • Sad but True says:

            Yes, but the point is that you could do away with taxation for most of these things and pay for them yourself as you wished, rather than having government force you to pay for them. So it’s not really a fair comparison anyway.

          • Anonymous says:

            taxation is a subject that is coming up more often at work.

            more early retirement and less working some going to three day weeks and such like are becoming discussed openly and becoming more common.

            these workers? oh, they are white, older, male, tax fodder.

          • Quiet Bat Person says:

            There is a fundamental problem with taxation. It is not used simply to raise revenues, but also, ostensibly, to modify behaviour.

            So, too reduce road traffic, and C02 production, for example, they put up fuel prices, road tax, etc.. But the more effective the deterrent, the less the tax it then raises.

            Also, there then arises the ridiculous situation where people, modifying their behaviour in response to punitive taxes, are then accused of tax avoidance, or worse, evasion.

          • Historyman says:

            How would you pay for defence yourself? A privatised soldier outside your door? Same for Police, Fireman, Ambulance driver, road sweeper, streetlamps?

          Only in Britain could the concept of ‘salary sacrifice’ exist. What a fuckin’ state Britain has become/ is becoming. We’re being treated like twats.

          Eeyore says:

          C’mon, that’s simply daft. You want not to to pay for the armed forces, police, courts, roads, border guards…..etc etc?

          Any sane person wants tax to be as low as possible, of course, but you don’t have to be a Guardian-reading loony to want essential services to be maintained.

          As to what constitutes ‘essential’ is up for debate, as is the matter of who operates them (mostly, my vote is against the civil service), but someone has to pay by some mechanism, and taxation is the least worst one we have.

        David Bouvier says:

        Problem is you are thinking about maximising the government tax take, by taxing to the point where the incremental tax collected is matched by the damage to the rest of the economy. This is taxing well beyond the point where significant economic damage is being done

        At the “sweet spot” let us imagine a marginal tax rate of 40p in the pound, so when £1 tax raised is met by £1 loss of taxes from economic activity, you are destroying £2.50 of economic activity to raise £1 in taxes. Well done.

        In case you hadn’t noticed the point of government is not actually to maximise the tax take at the expense of the public (though it certainly sometimes seems like that)

      Brown only lasted 13 years or is really from 2001 but started to be caught out from 2005, fleecing anyone from the UK.

      • 16
        The new Messiah says:

        Even an economic dummy like Brown must have known about the Laffer curve. That is why he only raised the higher rate by 10% when he knew he and his party were likely going to lose the election. And as a result we had three years of low growth. Only since Osborne had the bottle to lower the higher rate again has the economy started to take off.

          Glyn H says:

          Well thats income tax rather that corparation tax but it leads to the question: What would happen to the tax take if it was reduced back to 40% (still high). It would likely increase the take and Osborne was surely a fool to not reduce it immedately after the 2010 election. Liberal financial f******ds or what?

          • Norfolk's Finest says:

            We should get rid of Corporation Tax altogether. It only represents a small portion of the government’s tax take and if it disappeared, we’d be swamped with businesses the world over rushing to set up shop here and that would increase employment opportunities overnight. We’d go from having an economy that’s relatively in the doldrums to having an economic powerhouse within a couple of years and Britain would once again weald an almighty cloud on the world stage – effectively we’d have an empire again: a commercial one, if not a sovereign one.

    So now our George is concerned about increasing GDP .

    Well here is a good one; every Bank Holiday loses 0.1% of GDP.

    Cut 5 Bank Holidays out and GPD increases 0.5% resulting in 150,000 new jobs and new revenues for the Treasury.

    Go for it George.

      The Green Fairy says:

      The Laffer curve is one of the few bits of economics that is actually based on rigorous mathematics. If you tax at 0% you collect no tax (obviously); if you tax at 100% you collect no tax (because there’s no economic activity) – so (pure mathematics requires) somewhere between the two there is a tax rate that maximises your take. Where that percentage is to be found, is another question …

        Another question is whether the state exists to maximise the tax take in the first fucking place.

        They should provide a minimum package of those services best supplied by the state at the absolute minimum cost. End of story.

        There should be no bullshit about needing to pay highly to ‘compete’ with private sector remuneration for the simple reason that the state is not competing with anyone – the operation gets its money whether successful or not and cannot go bust.

        It is usually a simple matter to work out where by looking at historical data and making comparisons with other similar industrialised nations.

        However, politics then gets in the way…..

        It is easier to look at the matter from a different perspective. If you have a trade deficit then you have too little resource in the private sector and too much in the public sector and thus you need to re-balance. This inherently means reducing public sector spend to free up more human resource and more capital for the private sector.

    This shows just how out of touch George Osborne and David Cameron are, and is the sort of nonsense which could only be dreamed up by people who have never had a proper job, are financially supported by other members of their own family and/or who went to public school.

    Must go now: I have a meeting with Harriet and Tristram and then have to be at home to make sure it is clean before my wife gets back from her day job of charging squillions for being a barrister. After all, if I wasn’t the cleaner then nasty people would say that I have never had a proper job in my whole life …

    Of course they would have had to deal in foreign languages and foreign cultures, they would know that to succeed they had to have the world’s best engineers, scientists and mathematicians. and they would have organised society to achieve this.

    Instead they take the easy route, Eton, Oxford PPE and a comfortable living the old boy network….

    Who needs an economic model to realise that if you raise taxes, people will try to avoid them, if you lower them, they are more likely to pay? The Left are ideologically obsessed with the idea that you have to raise tax levels becos the nasty capitalists are secreting their money into offshore accounts. Not something the Left would ever do, of course. *innocent face* (without prejudice, m’lud).

    But no cuts for people until the next decade. This is obviously on the premise that Dave and Georges’ mates don’t do anything as vulgar as pay tax in the UK, whereas their companies just might.

    Really, the Tory Party only needs a 30 second party political broadcast in the run-up to the next election. A blank screen with a cheap actor saying “Fuck off and die” should suffice.

    “…In short, our primary challenge is not how to divide the economic pie, but how to enlarge it.”

    “…Every dollar released from taxation that is spent or invested will help create a new job and a new salary. And these new jobs and new salaries can create other jobs and other salaries and more customers and more growth for an expanding American economy.”

    “It is a paradoxical truth that tax rates are too high and tax revenues are too low and the soundest way to raise the revenues in the long run is to cut the rates now … Cutting taxes now is not to incur a budget deficit, but to achieve the more prosperous, expanding economy which can bring a budget surplus.”

    He might have been able to get democracy back again on the back of the tide of public support with boundary reform. Where is democracy when the results are skewed?

    John Milton Keynes says:

    I have long proposed a ‘Lefty Tax’. I propose that we identify well paid lefties and hit them with a ‘Hollande’ – a 75% rate kicking in at all income over £50,000. Think of the extra revenue to be gained on Rusbridger’s £600,000+ package, for example.

    The beauty of this scheme is that the lefties will back it. They like high taxes. They want large revenues to go to the state. I’m right about this, am I not lefties? You will back it?

  26. 73
    Lord Gaga says:

    We should have a duffer curve. It may not be possible to show how reducing taxation improves the exchequer, but showing that increasing it kills business its pretty simple. You only have to look at what tax on beer did to the affordable pint and the pub trade to see it in action, or look at the impact of business rates on the high street.

Cathy Jamieson MP, Labour’s Shadow Treasury minister, commenting on Treasury analysis of the economic impact of tax changes…

“If the Treasury is looking at the economic impact of tax changes, then surely it should examine the impact of the rise in VAT and cuts to tax credits? George Osborne’s £12 billion VAT rise knocked confidence, helped to choke off the recovery and has cost families £1,350 over the last three years.”
