Much of the east coast of England is subject to tidal flooding. One such area is the coastline around the Wash, the huge bay between Norfolk and Lincolnshire. Most of the vulnerable shorelines are protected by sea defences, usually in the form of concrete walls or earth embankments, traditionally paid for by the government. But part of the Norfolk shoreline is protected by shingle banks, which require annual maintenance.
Full government funding for maintaining these banks ended in 2013. According to new government rules, only projects that provide at least £8 of benefits for each £1 spent would qualify for such funding to continue. The area under question on the Norfolk cost of the Wash does not qualify.
Between 2013 and 2015 the work on the shingle banks is being paid for by the local council charging levies. After that, the plan is for a partnership-funding approach, where the government will make a (small) contribution as long as the bulk of the funding comes from the local community. This will involve setting up a ‘community interest company’, which will seek voluntary contributions from local residents, landowners and businesses.
Sea defences are a public good, in that it is difficult to exclude people benefiting who choose not to pay. In other words, there is a ‘free rider’ problem. However, in the case of the Wash shoreline in question, one borough councillor, Brian Long, argues that it might be possible to maintain the flood defences to protect those who do contribute while ignoring those who do not.
Not surprisingly, many residents and businesses argue that the government ought to fund the defences and, if it does have to be financed locally, then everyone should be required to pay their fair share.

- Is there a moral hazard if people choose to live in a coastal area that would be subject to flooding without sea defences?
- Who is the ‘public’ in the case of sea defences? Is it the whole country, or the local authority or just all those being protected by the defences?
- What are the problems with relying on voluntary contributions to fund, or partly fund, sea defences? How could the free-rider problem be minimised in such a funding model?

The UK Shadow Chancellor, Ed Balls, has announced that, if Labour is returned to power in the next election, it will bring back the 50% top rate of income tax (see also). This will apply to incomes over £150,000.
But will this raise more tax revenue? The question here concerns incentive effects. Will the higher rate of income tax discourage work by those earning £150,000 or encourage tax avoidance or tax evasion, so that the total tax take is reduced? The Conservatives say the answer is yes. The Labour party says no, claiming that there will still be an increase in tax revenue.
The possible effects are summed up in the Laffer curve (see The 50p income tax rate and the Laffer curve). As the previous post stated:
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) 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.
As Labour is claiming that re-introducing the 50% top rate of income tax will increase tax revenue, the implication is that the economy is to the left of the top of the Laffer curve: that, at current level of income, the curve is still rising.
Work by HMRC, and published in the document The Exchequer effect of the 50 per cent additional rate of income tax, suggested that the previous cut in the top rate from 50% to 45% would cut revenue by around £3.5 billion if there were no incentive effect, but with the extra work that would be generated, the cut would be a mere £100 million. This implies, other things being equal, that a rise in the rate from 45% to 50% would raise only a tiny bit of extra taxes.
However, the HMRC analysis has been criticised and especially its assumptions about the incentive effects on work. Then there is the question of whether a rise in the rate from 45% to 50% would have exactly the reverse effect of a cut from 50% to 45%. And then there is the question of how much HMRC could reduce tax evasion and avoidance.
The following article from the Institute for Fiscal Studies examines the effects. However, the authors conclude that:
… at the moment, the best evidence we have still suggests that raising the top rate of tax would raise little revenue and make, at best, a marginal contribution to reducing the budget deficit an incoming government would face after the next election.
But there is also the question of equity. Putting aside the question of how much revenue would be raised, is it fair to raise the top rate of tax for those on high incomes? Would it make an important contribution to reducing inequality? This normative question lies at the heart of the different views of the world between left and right and is not a question that can be answered by economic analysis.

50p tax – strolling across the summit of the Laffer curve? Institute for Fiscal Studies, Paul Johnson and David Phillips (Jan 2014)
Questions
- Distinguish between tax evasion and tax avoidance.
- How would it be possible for a rise in tax rates to generated less tax revenue?
- Could policies shift the Laffer curve as opposed to merely resulting in a move along the curve?
- What is meant by ‘taxable income elasticity (TIE)’? What are its determinants?
- Is the taxable income elasticity at the top of the Laffer curve equal to, above or below zero? Explain.
- Why did the Office for Budget Responsibility chairman, Robert Chote, conclude that, whatever the precise answer, we were ‘strolling across the summit of the Laffer curve’?
- Explain why ‘there is little additional evidence to suggest that a 50p rate would raise more than was estimated by HMRC back in 2012’.
- What contribution can economists make to the debate on the desirability of reducing inequality?
Growing inequality of income and wealth is a common pattern throughout the world. In the boom years up to 2008, the rich got a lot richer, but at least those on low incomes generally saw modest rises in their incomes. Since 2008, however, the continually widening gap between rich and poor has seen the poor and many on middle incomes getting absolutely poorer.
The problem is particularly acute in the USA. Indeed, in his 2012 State of the Union address, President Obama said that it was the ‘defining issue of our time.’
No challenge is more urgent. No debate is more important. We can either settle for a country where a shrinking number of people do really well, while a growing number of Americans barely get by. Or we can restore an economy where everyone gets a fair shot, everyone does their fair share, and everyone plays by the same set of rules.
The good news for the poor in the USA is that at last their incomes have stopped falling, thanks to stronger economic growth. But their share of the growth in GDP is tiny.
As The Economist article states:
The main message is a grim one. Most of the growth is going to an extraordinarily small share of the population: 95% of the gains from the recovery have gone to the richest 1% of people, whose share of overall income is once again close to its highest level in a century. The most unequal country in the rich world is thus becoming even more so.
Apart from the ethical question of whether it is desirable for a society, already highly unequal, to become even more so, there is the question of whether this growth in inequality threatens economic recovery. Joseph Stiglitz argues that the rich have a low marginal propensity to consume and that this is threatening recovery.
Then there is the question of investment. Because most Americans have not seen any significant rise in incomes, it is easy for them to believe that the country cannot afford to invest more. And certainly it is difficult to persuade people that higher taxes are warranted to fund education, infrastructure or research.
The following articles consider the problem and its implications and look at various policy alternatives.

Each year in November, the Living Wage Foundation publishes figures for the hourly living wage that is necessary for people to meet basic bills. The rate for London is calculated by the Greater London Authority and for the rest of the UK by the Centre for Research in Social Policy at Loughborough University.
The 2013 update was published on 4 November. The Living Wage was estimated to be £8.80 in London and £7.65 in the rest of the UK.
Two things need to be noted about the Living Wage rate. The first is that the figure is an average and thus does not take into account the circumstances of an individual household. Clearly households differ in terms of their size, the number of wage earners and dependants, the local costs of living, etc. Second, the figures have been reduced from what is regarded as the ‘reference’ living wage, which is estimated to be £9.08 outside London. The reason for this is that people earning higher incomes have seen their living standards squeezed since 2009, with prices rising faster than average post-tax-and-benefit wages. Thus, the Living Wage is capped to reflect the overall decline in living standards. As the Working Paper on rates outside London explains:
From 2012 onwards, two kinds of limit have been put on the amount that the Living Wage as applied can rise in any one year. The first limits the increase in the net income (after taxes and benefits) requirement for each household on which the living wage calculation is based, relative to the rise in net income that would be achieved by someone on average earnings. The second limits the increase in the living wage itself (representing gross income) relative to the increase in average earnings.
Nevertheless, despite this capping of the living wage, it is still significantly higher than the UK National Minimum Wage, which currently stands at £6.31 for those aged 21 and over. This can be seen from the chart (click here for a PowerPoint).
Paying the Living Wage is voluntary for employers, but as The Guardian reports:
A total of 432 employers are now signed up to the campaign, up from 78 this time last year, including Legal & General, KPMG, Barclays, Oxfam, Pearson, the National Portrait Gallery and First Transpennine Express, as well as many smaller businesses, charities and town halls. Together they employ more than 250,000 workers and also commit to roll out the living wage in their supply chain.
But as The Observer reports:
The number of people who are paid less than a ‘living wage’ has leapt by more than 400,000 in a year to over 5.2 million, amid mounting evidence that the economic recovery is failing to help millions of working families.
A report for the international tax and auditing firm KPMG also shows that nearly three-quarters of 18-to-21-year-olds now earn below this level – a voluntary rate of pay regarded as the minimum to meet the cost of living in the UK. The KPMG findings highlight difficulties for ministers as they try to beat back Labour’s claims of a “cost of living crisis”.
According to the report, women are disproportionately stuck on pay below the living wage rate, currently £8.55 in London and £7.45 elsewhere. Some 27% of women are not paid the living wage, compared with 16% of men. Part-time workers are also far more likely to receive low pay than full-time workers, with 43% paid below living-wage rates compared with 12% of full-timers.
But although paying a living wage may be desirable in terms of equity, many firms, especially in the leisure and retailing sectors, claim that they simply cannot afford to pay the living wage and, if they were forced to, would have to lay off workers.
The point they are making is that it is not economical to pay workers more than their marginal revenue product. But this raises the question of whether a higher wage would encourage people to work more efficiently. If it did, an efficiency wage may be above current rates for many firms. It also raises the question of whether productivity gains could be negotiated in exchange for paying workers a living wage
These arguments are discussed in the following podcast.

Questions
- How is the Living Wage calculated?
- What are the reasons for announcing a Living Wage figure that is lower than a reference living wage? Assess these reasons.
- If there are two separate figures for the Living Wage for London and the rest of the UK, would it be better to work out a living wage for each part, or even location, of the UK?
- Why might it be in employers’ interests to pay at least the Living Wage? Does this explain why more and more employers are volunteering to pay it?
- Assess the Labour Party’s pledge, if they win the next election, that ‘firms which sign up to the living wage will receive a tax rebate of up to £1000 for every low-paid worker who gets a pay rise, funded by tax and national insurance revenue from the higher wages’.
- Which is fairer: to pay everyone at least the Living Wage or to use tax credits to redistribute incomes to low-income households?
According to the Sunday Times Rich List, the combined wealth of Britain’s 1000 richest people grew by nearly 4.7% last year to £414 billion (after growing by 18% in 2010).
This is in stark contrast to average households, who saw their real incomes decline by 1.9% in 2011. As the Guardian article below says:
The Rich Listers are not merely the 1%, but the 0.01%, and this fanfared celebration of their assets feels like a celebration of things that nobody feels like celebrating: bankers’ bonuses, complex corporate tax-avoidance structures, the stifling grip of aristocratic family wealth.
So why are the rich getting richer and what are the implications for society and the economy? Watch and read the following webcasts and articles and then see if you can answer the questions below.
