A recent report published by the High Pay Centre shows that the median annual CEO pay of the FTSE 100 companies rose by 15.7% in 2022, from £3.38 million in 2021 to £3.91 million – double the UK CPIH inflation rate of 7.9%. Average total pay across the whole economy grew by just 6.0%, representing a real pay cut of nearly 2%.

The pay of top US CEOs is higher still. The median annual pay of S&P 500 CEOs in 2022 was a massive $14.8 million (£11.7 million). However, UK top CEOs earn a little more than those in France and Germany. The median pay of France’s CAC40 CEOs was €4.9 million (£4.2 million). This compares with a median of £4.6 million for the CEOs of the top 40 UK companies. The mean pay of Germany’s DAX30 CEOs was €6.1 million (£5.2 million) – lower than a mean of £6.0 million for the CEOs of the top 30 UK companies.

The gap between top CEO pay and that of average full-time workers narrowed somewhat after 2019 as the pandemic hit company performance. However, it has now started widening again. The ratio of the median UK CEO pay to the median pay of a UK full-time worker stood at 123.1 in 2018. This fell to 79.1 in 2020, but then grew to 108.1 in 2021 and 118.1 in 2022.

The TUC has argued that workers should be given seats on company boards and remuneration committees that decide executive pay. Otherwise, the gap is likely to continue rising, especially as remuneration committees in specific companies seek to benchmark pay against other large companies, both at home and abroad. This creates a competitive upward push on remuneration. What is more, members of remuneration committees have the incentive to be generous as they themselves might benefit from the process in the future.

Although the incomes of top CEOs is huge and growing, even if they are excluded, there is still a large gap in incomes between high and low earners generally in the UK. In March 2023, the top 1 per cent of earners had an average gross annual income of just over £200 000; the bottom 10 per cent had an average gross annual income of a little over £8500 – just 4.24% of the top 1 per cent (down from 4.36% in March 2020).

What is more, in recent months, the share of profits in GDP has been rising. In 2022 Q3, gross profits accounted for 21.2% of GDP. By 2023 Q2, this had risen to 23.4%. As costs have risen, so firms have tended to pass a greater percentage increase on to consumers, blaming these price increases on the rise in their costs.

Life at the bottom

The poor spend a larger proportion of their income on food, electricity and gas than people on average income; these essential items have a low income elasticity of demand. But food and energy inflation has been above that of CPIH inflation.

In 2022, the price of bread rose by 20.5%, eggs by 28.9%, pasta by 29.1%, butter by 29.4%, cheese by 32.6% and milk by 38.5%; the overall rise in food and non-alcoholic beverages was 16.9% – the highest rise in any of the different components of consumer price inflation. In the past two years there has been a large increase in the number of people relying on food banks. In the six months to September 2022, there was a 40% increase in new food bank users when compared to 2021.

As far as energy prices are concerned, from April 2022 to April 2023, under Ofgem’s price cap, which is based on wholesale energy prices, gas and electricity prices would have risen by 157%, from £1277 to £3286 for the typical household. The government, however, through the Energy Price Guarantee restricted the rise to an average of £2500 (a 96% rise). Also, further help was given in the form of £400 per household, paid in six monthly instalments from October 2022 to March 2023, effectively reducing the rise to £2100 (64%). Nevertheless, for the poorest of households, such a rise meant a huge percentage increase in their outgoings. Many were forced to ‘eat less and heat less’.

Many people have got into rent arrears and have been evicted or are at risk of being so. As the ITV News article and videos linked below state: 242 000 households are experiencing homelessness including rough sleeping, sofa-surfing and B&B stays; 85% of English councils have reported an increase in the number of homeless families needing support; 97% of councils are struggling to find rental properties for homeless families.

Financial strains have serious effects on people’s wellbeing and can adversely affect their physical and mental health. In a policy research paper, ‘From Drained and Desperate to Affluent and Apathetic’ (see link below), the consumer organisation, Which?, looked at the impact of the cost-of-living crisis on different groups. It found that in January 2023, the crisis had made just over half of UK adults feel more anxious or stressed. It divided the population into six groups (with numbers of UK adults in each category in brackets): Drained and Desperate (9.2m), Anxious and At Risk (7.9m), Cut off by Cutbacks (8.8m), Fretting about the Future (7.7m), Looking out for Loved Ones (8.9m), Affluent and Apathetic (8.8m).

The majority of the poorest households are in the first group. As the report describes this group: ‘Severely impacted by the crisis, this segment has faced significant physical and mental challenges. Having already made severe cutbacks, there are few options left for them.’ In this group, 75% do not turn the heating on when cold, 63% skip one or more meals and 94% state that ‘It feels like I’m existing instead of living’.

Many of those on slightly higher incomes fall into the second group (Anxious and At Risk). ‘Driven by a large family and mortgage pressure, this segment has not been particularly financially stable and experienced mental health impacts. They have relied more on borrowing to ease financial pressure.’

Although inflation is now coming down, prices are still rising, interest rates have probably not yet peaked and real incomes for many have fallen significantly. Life at the bottom has got a lot harder.

In her bid to become Conservative party leader, Liz Truss promised to make achieving faster economic growth her number-one policy objective. This would involve pursuing market-orientated supply-side policies.

These policies would include lower taxes on individuals to encourage people to work harder and more efficiently, and lower taxes on business to encourage investment. The policy would also involve deregulation, which would again encourage investment, both domestic and inward investment from overseas. These proposals echoed the policies pursued in the 1980s by President Ronald Reagan in the USA and Margaret Thatcher in the UK.

On September 23, the new Chancellor, Kwasi Kwarteng, presented a ‘mini-Budget’ – although the size of the changes made it far from ‘mini’. This, as anticipated, included policies intended to boost growth, including scrapping the 45% top rate of income tax, which is currently paid by people earning over £150 000 (a policy withdrawn on 3 October after massive objections), cutting the basic rate of income tax from 20% to 19%, scrapping the planned rise in corporation tax from 19% to 25%, scrapping the planned rise in national insurance by 1.25 percentage points, a cut in the stamp duty on house purchase and scrapping the limit placed on bankers’ bonuses. In addition, he announced the introduction of an unlimited number of ‘investment zones’ which would have lower business taxes, streamlined planning rules and lower regulation. The policies would be funded largely from extra government borrowing.

Theoretically, the argument is simple. If people do work harder and firms do invest more, then potential GDP will rise – a rise in aggregate supply. This can be shown on an aggregate demand and supply diagram. If the policy works, the aggregate supply curve will shift to the right. Real GDP will rise and there will be downward pressure on prices. In Figure 1, real GDP will rise from Y0 to Y1 and the price level will fall from P0 to P1. However, things are not as simple as this. Indeed, there are two major problems.

The first concerns whether tax cuts will incentivise people to work harder. The second concerns what happens to aggregate demand. I addition to this, the policies are likely to have a profound effect on income distribution.

Tax cuts and incentives

Cutting the top rate of income tax would have immediately given people at the top of the income scale a rise in post-tax income. This would have created a substitution effect and an income effect. Each extra pound that such people earn would be worth more in post-tax income – 60p rather than 55p. This would provide an incentive for people to substitute work for leisure as work is now more rewarding. This is the substitution effect. On the other hand, with the windfall of extra income, they now would have needed to work less in order to maintain their post-tax income at its previous level. They may well indeed, therefore, have decided to work less and enjoy more leisure. This is the income effect.

With the diminishing marginal utility of income, generally the richer people are, the bigger will be the income effect and the smaller the substitution effect. Thus, cutting the top rate of income tax may well have led to richer people working less. There is no evidence that the substitution effect would be bigger.

If top rates of income tax are already at a very high level, then cutting then may well encourage more work. After all, there is little incentive to work more if the current rate of tax is over 90%, say. Cutting them to 80% could have a big effect. This was the point made by Art Laffer, one of Ronald Reagan’s advisors. He presented his arguments in terms of the now famous ‘Laffer curve’, shown in Figure 2. This shows the total tax revenue raised at different tax rates.

If the average tax rate were zero, no revenue would be raised. As the tax rate is raised above zero, tax revenues will increase. The curve will be upward sloping. Eventually, however, the curve will peak (at tax rate t1). Thereafter, tax rates become so high that the resulting fall in output more than offsets the rise in tax rate. When the tax rate reaches 100 per cent, the revenue will once more fall to zero, since no one will bother to work.

If the economy were currently to the right of t1, then cutting taxes would increase revenue as there would be a major substitution effect. However, most commentators argue that the UK economy is to the left of t1 and that cutting the top rate would reduce tax revenues. Analysis by the Office for Budget Responsibility in 2012 suggested that t1 for the top rate of income tax was at around 48% and that cutting the rate below that would reduce tax revenue. Clearly according to this analysis, 40% is considerably below t1.

As far as corporation tax is concerned, the 19% rate is the lowest in the G20 and yet the UK suffers from low rates of both domestic investment and inward direct investment. There is no evidence that raising it somewhat, as previously planned, will cut investment. And as far as individual entrepreneurs are concerned, cutting taxes is likely to have little effect on the desire to invest and expand businesses. The motivation of entrepreneurs is only partly to do with the money. A major motivation is the sense of achievement in building a successful business.

Creating investment zones with lower taxes, no business rates and lower regulations may encourage firms to set up there. But much of this could simply be diverted investment from elsewhere in the country, leaving overall investment little changed.

To assess these questions, the government needs to model the outcomes and draw on evidence from elsewhere. So far this does not seem to have happened. They government did not even present a forecast of the effects of its policies on the public finances, something that the OBR normally presents at Budget time. This was one of the reasons for the collapse in confidence of sterling and gilts (government bonds) in the days following the mini-Budget.

Effects on aggregate demand

Cutting taxes and financing them from borrowing will expand aggregate demand. In Figure 1, the AD curve will also shift to the right and this will push up prices. Inflation is already a serious problem in the economy and unfunded tax cuts will make it worse. Higher inflation will result in the Bank of England raising interest rates further to curb aggregate demand. But higher interest rates, by raising borrowing costs, are likely to reduce investment, which will have a negative supply-side effect.

The problem here is one of timing. Market-orientated supply-side policies, if they work to increase potential GDP, will take time – measured in years rather than months. The rise in aggregate demand will be much quicker and will thus precede the rise in supply. This could therefore effectively kill off the rise in supply as interest rates rise, the exchange rate falls and the economy is pushed towards recession. Indeed, the mini-Budget immediately sparked a run on the pound and the exchange rate fell.

The rising government debt may force the government to make cuts in public expenditure. Rather than cutting current expenditure on things such as nurses, teachers and benefits, it is easier to cut capital expenditure on things such as roads and other infrastructure. But this will have adverse supply-side effects.

Effects on income distribution

Those advocating market-orientated supply-side policies argue that, by making GDP bigger, everyone can gain. They prefer to focus on the size of the national ‘pie’ rather than its distribution. If the rich initially gain, the benefits will trickle down to the poorest in society. This trickle-down theory was popular in the 1980s with politicians such as Margaret Thatcher and Ronald Reagan and, more recently, with Republican presidents, such as Goerge W Bush and Donald Trump. There are two problems with this, however.

The first, which we have already seen, is whether such policies actually do increase the size of the ‘pie’.

The second is how much does trickle down. During the Thatcher years, income inequality in the UK grew, as it did in the USA under Ronald Reagan. According to an IMF study in 2015 (see the link to the IMF analysis below), policies that increase the income share of the poor and the middle class do increase growth, while those that raise the income share of the top 20 per cent result in lower growth.

After the mini-Budget was presented, the IMF criticised it for giving large untargeted tax cuts that would heighten inequality. The poor would gain little from the tax cuts. The changes to income tax and national insurance mean that someone earning £20 000 per year will gain just £167 per year, while someone earning £200 000 will gain £5220. What is more, the higher interest rates and higher prices resulting from the lower exchange rate are likely to wipe out the modest gains to the poor.

Economists are often criticised for making inaccurate forecasts and for making false assumptions. Their analysis is frequently dismissed by politicians when it contradicts their own views.

But is this fair? Have economists responded to the realities of the global economy and to the behaviour of people, firms, institutions and government as they respond to economic circumstances? The answer is a qualified yes.

Behavioural economics is increasingly challenging the simple assumption that people are ‘rational’, in the sense that they maximise their self interest by weighing up the marginal costs and benefits of alternatives open to them. And macroeconomic models are evolving to take account of a range of drivers of global growth and the business cycle.

The linked article and podcast below look at the views of 2019 Nobel Prize-winning economist Esther Duflo. She has challenged some of the traditional assumptions of economics about the nature of rationality and what motivates people. But her work is still very much in the tradition of economists. She examines evidence and sees how people respond to incentives and then derives policy implications from the analysis.

Take the case of the mobility of labour. She examines why people who lose their jobs may not always move to a new one if it’s in a different town. Partly this is for financial reasons – moving is costly and housing may be more expensive where the new job is located. Partly, however, it is for reasons of identity. Many people are attached to where they currently live. They may be reluctant to leave family and friends and familiar surroundings and hope that a new job will turn up – even if it means a cut in wages. This is not irrational; it just means that people are driven by more than simply wages.

Duflo is doing what economists typically do – examining behaviour in the light of evidence. In her case, she is revisiting the concept of rationality to take account of evidence on what motivates people and the way they behave.

In the light of workers’ motivation, she considers the implications for the gains from trade. Is free trade policy necessarily desirable if people lose their jobs because of cheap imports from China and other developing countries where labour costs are low?

The answer is not a clear yes or no, as import-competing industries are only part of the story. If protectionist policies are pursued, other countries may retaliate with protectionist policies themselves. In such cases, people working in the export sector may lose their jobs.

She also looks at how people may respond to a rise or cut in tax rates. Again the answer is not clear cut and an examination of empirical evidence is necessary to devise appropriate policy. Not only is there an income and substitution effect from tax changes, but people are motivated to work by factors other than take-home pay. Likewise, firms are encouraged to invest by factors other than the simple post-tax profitability of investment.

There has been considerable discussion recently about whether the government should introduce a property tax on high value properties. The government, finding it difficult to reduce the public-sector deficit and yet determined to do so, is looking for additional measures to reduce government expenditure or raise tax revenue.

But would it favour a mansion tax as a means of raising additional revenue?

The imposition of such a tax is favoured by both Liberal Democrats and the Labour Party. It is strongly opposed, however, by Conservatives. But just what would such a tax look like and what are the arguments for and against it?

One alternative would be to impose a one-off tax on property valued over a certain amount, such as £2 million. Alternatively it could be levied only for as long as the government is seeking to make substantial inroads into the deficit.

Another would be to add one or more bands to council tax. At present, council tax in England is levied in 8 bands according to the value of a person’s property. The highest band is for property valued over £320,000 in 1991 prices, with the amount of tax due for each band varying from local authority to local authority. (Average UK house prices in 2012 are 135% higher than in 1991.) In Scotland the bands are lower with the top band being for property valued over £212,000 in 1991 prices. In Wales, there is an additional band for property valued over £424,000, but properties are valued in 2003 prices, not 1991 prices.

With low top bands for council tax, people in mansions end up paying the same as people in much more modest property. It would be relatively easy to add additional bands, with the top band applying only to property worth, say, over £1 million or more.

The arguments in favour of a mansion tax are that it is progressive, relatively easy to collect, hard to evade and with minimal disincentive effects. The arguments against are that it would make the tax system ‘too progressive’, would not necessarily be related to an individual’s ability to pay and could have substantial disincentive effects.

The progressiveness of the UK tax system is illustrated in the chart, which looks at the proportion of income paid in direct, indirect and all taxes by quintile groups of households – that is, households grouped into five equal sized groups ranked from lowest to highest gross income. (Click here for a PowerPoint of the chart.)

The following articles look at the debate as it has raged over the past few weeks. Try to unpick the genuine arguments from the political rhetoric!

Let’s face it – no-one likes paying tax! After all, to see your monthly pay decline by £1000 through taxation and national insurance has got to hurt. Yet, taxation and national insurance contributions are essential sources of government revenue to finance benefits and public and merit goods.

However, with so much attention given to the UK’s ‘culture of dependency’, many people are increasingly angry with having to pay so much in taxation to see it being spent by the government on individuals who in some cases choose not to work and at the same time seeing other rich people paying so little in taxation. The increase in the top rate of tax received a lot of coverage. Although it did make the tax system more progressive, there were many concerns that it would lead to lower growth, a lack of innovation and enterprise and increased tax evasion and avoidance, as the super-rich were being hit with phenomenal tax bills. The post on the 50p income tax available here is worth looking at again to think about the effect that taxes have on incentives.

The issue of tax avoidance is by no means new, but with a large budget deficit in the UK, tax avoidance by the super-rich has become something that everyone has an opinion on. The average household has seen its income squeezed more and more, as the government continues its efforts to cut the deficit. The fact that the super rich are avoiding sometimes millions in taxation, while the average household struggles to pay even the basic rate of tax, creates a rather contentious issue. The Chief Secretary to the Treasury, Danny Alexander, has said that the basic rate of tax could be cut by 2p in the pound if tax avoidance came to an end. He commented to the BBC’s Sunday Politics Programme that:

‘We have to make sure that everybody, especially the rich and famous, are paying their fair share of tax…These sorts of schemes that save wealthy people potentially tens of millions of pounds in tax, they are paid for by everybody else… If we could narrow the tax gap in this country by a quarter we could reduce income tax for every basic rate payer by 2p in the pound.’

This would clearly have some very positive effects on some of the poorest people living in the UK.

There is a variety of tax avoidance schemes available and the one receiving the most attention at present is the Jersey-based K2 scheme, which Jimmy Carr and others are thought to be using. The Public Accounts Committee will be reporting on the problem of using private companies to pay salaries, as a means of avoiding income tax and national insurance contributions.

If tax avoidance could be stopped, or at least reduced, then not only could basic rate tax payers benefit, but it might go some way to cutting the budget deficit, giving the government more flexibility in stimulating the economy. According to HMRC, tax avoidance and evasion cost the economy some £42 billion – enough to pay off one-third of Britain’s budget deficit.
