Recently there have been calls from business leaders and Conservative politicians to scrap the UK’s 50% income tax rate, which is paid on taxable incomes over £150,000. The 50% income tax rate is thus paid by top earners, who comprise around just 1% of taxpayers.
And yet the government receives about 30% of income tax revenue from this 1% – and this was before the introduction of the 50% rate in April 2010. (In fact, with the marginal national insurance rate of 2%, top earners are paying an effective marginal rate of 52%.)
One argument used by those who favour reducing the 50% rate is that the rich would pay more income tax, not less. There are four reasons given for this. The first is that people would be encouraged to work harder and/or seek promotion if they knew they would keep more of any rise in income. The second is that fewer rich people would be encouraged to leave the country or to relocate their businesses abroad. The third is that more people would be encouraged to work in or set up businesses in the UK. The fourth is that there would be less temptation to evade taxes by not declaring all income earned or to find clever ways of avoiding tax.
These arguments were put forward in the 1980s by Art Laffer, an adviser to President Reagan. His famous ‘Laffer curve’ (see Economics (8th edition) Box 10.3 or Economics (7th edition) Box 10.4) illustrated that tax revenues are maximised at a particular tax rate. The idea behind the Laffer curve is very simple. At a tax rate of 0%, tax revenue will be zero – but so too at a rate of 100%, since no-one would work if they had to pay all their income in taxes. As the tax rate rises from 0%, so tax revenue would rise. And so too, as the tax rate falls from 100%, the tax rate would rise. It follows that there will be some tax rate between 0% and 100% that maximises tax revenue.
Those arguing that a cut in the top rate of income tax would increase tax revenue are arguing that the 50% rate is beyond the peak of the Laffer curve. But this is an empirical issue. In other words, to assess the argument you would need to look at the evidence as, theoretically, the peak of the Laffer curve could be below or above 50%. Indeed, some argue that the peak is more likely to be at around 75%.
The following podcasts and articles consider the arguments. As you will see, the authors are not all agreed! Consider carefully their arguments and try to identify any flaws in their analysis.
Update
On 27 June 2012, Arthur Laffer appeared on the BBC Today Programme to discuss the Laffer curve and its implications for UK income tax policy. You can hear it from the link below

Questions
- Explain how a cut in income tax could lead to an increase in tax revenue.
- Distinguish between the income effect and the substitution effect of a tax cut. Which would have to be bigger if a tax cut were to increase tax revenue?
- If, in a given year, the top rate of tax were raised and tax revenue fell, would this prove that the economy was now past the peak of the Laffer curve?
- What would cause the Laffer curve to shift/change shape? To what extent could the government affect the shape of the Laffer curve?
- If the government retains the 50% top tax rate, what can it do to increase the revenue earned from people paying the top rate?
- What other objectives might the government have for having a high marginal income tax rate on top earners?
- Investigate the marginal income tax and national insurance (social protection) rates in other countries. How progressive are UK income taxes compared with those in other countries?
Will we soon live in a world without cash? More and more payments are being made electronically: whether by credit card or debit card, or by direct debit or bank transfer, or by cash loaded cards. For many people cash is now largely used only for small transactions.
But even here, things are changing. Direct transfers via mobile phone apps are increasingly being used for small transactions. Mobile phone companies, banks and others are busy developing such apps and more and more are being released onto the market.
And it’s not just in developed countries. Many developing countries are finding that mobile phones are an ideal way of transferring money for a whole range of transactions. For example, in Kenya, under 20% have a formal bank account, only 1% have a landline and yet more than 70% have a mobile phone, and this percentage is still rising. In 2007, a system known as M-Pesa (see also) was launched:
The user can create a free account and deposit money into it for free with registered agents at retail outlets. They may be gas stations, supermarkets, banks or micro-finance providers or small and medium-sized businesses. No minimum account balance is required.
The user can then transfer up to $440 from the account to someone else — including someone who doesn’t have a cellphone. The recipient provides identification and picks up the cash from another registered agent.
Users can deposit and withdraw cash, pay water and electricity bills, pay their children’s school fees, get paid by their employers or buy extra airtime for their phone.
Other developing countries are introducing similar systems. The second webcast link below gives an example from South Africa.
So how long will it be before cash disappears as a medium of exchange? Or will people continue to prefer to carry cash around with them – especially given the convenience of having cash machines readily available which do not charge for use.

With falling GDP and house prices, Spanish banks have been running the risk of failure. Indeed, the Spanish government has already had to agree to bail out Spain’s fourth biggest bank, Bankia.
On Saturday 9 June, at a crisis conference call, eurozone finance ministers agreed to lend the Spanish government up to €100 billion to provide credit to Spanish banks. The Spanish government is commissioning independent audits of the banks and, in the light of that, will specify just how much it needs to borrow.
Details of the nature of the loans will be made clear over the coming days, but they will funded either from the temporary rescue fund, the European Financial Stability Facility (EFSF), or from the new permanent fund that will replace it, the European Stability Mechanism (ESM).
But whilst the loans will remove the immediate pressure on Spanish banks, the underlying problems of the Spanish economy remain. Easy credit fuelled a property bubble which then burst. House prices have fallen by over 20% since the peak, and many Spanish people are in negative equity. Many construction companies have gone out of business.
What is more, the Spanish government is committed to reducing the budget deficit from 8.9% of GDP in 2011 to 5.3% in 2012 and 3% in 2013. To achieve this it has instituted tough austerity policies of government expenditure cuts and tax rises. (Click here for a link to a graph from the BBC of budget deficits in 18 EU countries.)
This has only aggravated the decline in GDP – at least in the short term. Spanish GDP is set to fall by around 2% this year and unemployment, at nearly 25% and rising, is the highest in Europe. Indeed the unemployment rate for those aged 15 to 25 is over 51%! This clearly has profound social and political consequences, with many young people seeing no prospect of gaining employment and thus feeling socially alienated. (For a PowerPoint of the above chart, click here.)
Markets on the Monday after the bailout was announced initially reacted positively. By the end of the day, however, the gains had been wiped out. Although no conditions were imposed on the Spanish government – the loan, although to the Spanish government, was to bail out the banks, not the government itself – worries remain that the Spanish economy is not set to recover for some time.
What is more, worries about other eurozone countries in difficulty have not gone away. Indeed, with the Spanish government being seen as having been dealt with more leniently than the Greek, Portuguese and Irish governments, investors are now worried that these countries may demand to renegotiate the terms of their bailout. And in the case of Greece, the Spanish bailout may make people more willing to vote in this coming Saturday’s election for parties that reject the Greek bailout terms. This may make it more likely that Greece will be forced to leave the euro, with all the chaos that is likely to ensue.

Paul Volcker was Chair of the US Federal Reserve from 1979 to 1987. He was also Chair of the Economic Recovery Advisory Board under President Barack Obama from February 2009 to January 2011. In the webcast and articles below, he reflects on the current state of the world financial system – from regulation, to the euro crisis, to world imbalances, to the system of floating exchange rates.
He argues that global financial systems are vulnerable to breakdowns. What is needed is reform to the system, and for that there needs to be consensus by politicians, regulators and central banks.
But, in the absence of international consensus on some key points, reform will be greatly weakened, if not aborted. The freedom of money, financial markets and people to move – and thus to escape regulation and taxation – might be an acceptable, even constructive, brake on excessive official intervention, but not if a deregulatory race to the bottom prevents adoption of needed ethical and prudential standards.
Perhaps most important is a coherent, consistent approach to dealing with the imminent failure of “systemically important” institutions. Taxpayers and governments alike are tired of bailing out creditors for fear of the destructive contagious effects of failure – even as bailouts encourage excessive risk-taking.
According to Volcker, countries must be prepared to surrender some sovereignty. Policies must be co-ordinated internationally and there must be stronger regulation by international bodies, such as the IMF and stronger concerted action by global organisations, such as the G20.
Left to their own devices, in an era of floating exchange rates, countries may pursue policies that exacerbate global imbalances.
Not so long ago, we were comforted by theorising that floating exchange rates would mediate international adjustments in a timely and orderly way. But, in the real world, many countries, particularly but not limited to small, open economies, simply find it impractical or undesirable to permit their currency to float.
We are left with the certainty, however awkward, that active participation in an open world economy requires some surrender of economic sovereignty. Or, to put the point more positively, it requires a willingness to co-ordinate policies more effectively.

A bumper olive crop in Spain would seem to be good news for Spanish olive growers. But the effect has been a fall in the prices of olives and olive oil. With 43% of the global supply, Spain is the world’s largest olive oil producer and changes in Spanish output have a big effect on the world price.
Premium extra virgin olive oil has fallen to its lowest level (even in nominal terms) since 2002. Today the price is around $2900 (£1850) a tonne in the wholesale market; in May 2006 it peaked at nearly $5854 – double today’s price.
And while this is bad news for Spanish farmers, for farmers in countries without bumper harvests, the low prices are even harder to bear.
The problem is being exacerbated by a fall in demand in many countries currently suffering recession, such as Greece, Portugal and Italy – all big olive oil consumers. Although olive oil prices have fallen, it is still more expensive than various substitutes. Many people are thus buying these cheaper alternatives, such as sunflower oil, especially for cooking.
What is more, cheaper substitutes for olive oil are increasing in supply. Take the case of rape seed oil in the UK. As the Mail Online article, linked to below, reports:
“UK rape planting is thought to have hit an all-time high this year as British farmers take advantage of the high prices being demanded for rapeseed – base ingredient of many vegetable oils and other edible oils.
Much of the UK crop is used by the local food industry, although some analysts are predicting strong UK yields will give farmers the opportunity to export more to Europe. Because of rising export demand, oil users in the UK claim there is little to indicate the price they are paying for rapeseed oil will drop substantially in the near future.”
The market for olive oil is global. Crop yields in one part of the world, both of olives and of substitute crops, affect global prices and hence growers’ incomes worldwide.
