Tax avoidance has been in the news since the publication of the Panama papers, which show the use of offshore tax havens by rich individuals and companies, partly for tax avoidance, partly for money laundering and other criminal activities – some by corrupt politicians and their associates – and partly to take advantage of lower regulation of financial dealing.
There are many tax havens around the world, including Switzerland, Hong Kong, British overseas territories (such as the British Virgin Islands, the Cayman Islands and Bermuda), Jersey, Singapore and certain US states
(such as Arizona, Delaware, Nevada and Wyoming).
Here we focus on tax avoidance. This is the management of tax affairs by individuals or firms so as to avoid or minimise the payment of taxes. Tax avoidance is legal, unlike tax evasion, which is the practice of not declaring taxable income.
In a statement from the White House, directly after the publication of the Panama papers, President Obama spoke about the huge international scale of tax evasion and tax avoidance:
“A lot of it is legal, but that’s exactly the problem. It’s not that [people are] breaking the laws, it’s that the laws are so poorly designed that they allow people, if they’ve got enough lawyers and enough accountants, to wiggle out of responsibilities that ordinary citizens are having to abide by.
Here in the United States, there are loopholes that only wealthy individuals and powerful corporations have access to. They have access to offshore accounts, and they are gaming the system. Middle-class families are not in the same position to do this. In fact, a lot of these loopholes come at the expense of middle-class families, because that lost revenue has to be made up somewhere. Alternatively, it means that we’re not investing as much as we should in schools, in making college more affordable, in putting people back to work rebuilding our roads, our bridges, our infrastructure, creating more opportunities for our children.”

Tax avoidance, whether in tax havens, or through exploiting loopholes in the tax system may be legal. But is it fair?
Various principles of a tax system can be identified. These include:
|
• |
Horizontal equity |
People in the same situation should be treated equally. For example, people earning the same level of income and with the same personal circumstances (e.g. number and type of dependants, size of mortgage, etc.) should pay the same level of income tax. |
• |
Vertical equity |
Taxes should be ‘fairly’ apportioned between rich and poor. The rich should pay proportionately more taxes than the poor. |
• |
Equity between recipients of government services |
Under the ‘benefit principle’, it is argued that those who receive the most benefits from government expenditure ought to pay the most in taxes. For example, it can be argued that roads should be paid for from fuel tax. |
• |
Difficulty of evasion and possibly of avoidance |
If it is desirable to have a given tax, people should not be able to escape paying. |
• |
Non-distortion |
Taxes alter market signals: taxes on goods and services alter market prices; taxes on income alter wages. They should not do this in an undesirable direction. |
• |
Convenience to the taxpayer |
Taxes should be certain and clearly understood by taxpayers so that they can calculate their tax liabilities. The method of payment should be straightforward. |
• |
Convenience to the government |
Tax rates should be simple to adjust and as cheap to collect as possible. |
• |
Minimal disincentive effects |
Taxes may discourage people from working longer or harder, from saving, from investing or from taking initiative. It is desirable that these disincentives should be kept to a minimum. |
Of course, not all these requirements can be met at the same time. One of the most serious conflicts is between vertical equity and the need to keep disincentives to a minimum. The more steeply the rich are taxed, it is argued, the more serious are the disincentive effects on them likely to be (see the blog post from 2012, The 50p income tax rate and the Laffer curve). Another is between vertical equity and equity between recipients of services. Some of the people most in need of government support are the poorest and hence pay the least taxes.
The crucial question is what is regarded as ‘fair’. What is vertically equitable? According to the second article below, people’s preferred tax rates depend on how information is presented. If information is presented on how much tax is paid by the rich, people generally feel that the rich pay too much. If, however, information is presented on how much income people are left with after paying tax, people feel that the rich still have too much and ought to pay more tax.
The majority of people in the UK feel that tax avoidance, although legal, is morally wrong. According to the results of an HMRC survey in 2015, “the majority (63%) of respondents felt that the use of tax avoidance schemes was widespread. However, the majority (61%) also responded that it was never acceptable to use a tax avoidance scheme. The most frequent reason given as to why it was unacceptable was that ‘it is unfair on others who pay their taxes’.”
In making judgements about the fairness of tax, people generally have inaccurate knowledge about the distribution of income, believing that it is more equal than it really is, and about the progressiveness of the tax system, believing that it is more progressive than it really is. Despite this, they want post-tax income distribution to be more equal.
What is more, although people generally disapprove of tax avoidance, it is the system that allows the avoidance of taxes that they want changing. As long as it is possible to avoid taxes, such as giving gifts to children to avoid inheritance tax (as long as the gift is made more than seven years before the person’s death), most people see no reason why they should not do so themselves.

In a blog post on 1 May this year, What’s really on offer?, we looked at the ‘super-complaint‘ by Which? to the Competition and Markets Authority (CMA) about supermarket special offers. The complaint referred to bogus price reductions, ‘cheaper’ multi-buys which weren’t cheaper, smaller pack sizes and confusing special offers. Under the rules of super-complaints, the CMA had 90 days from the receipt of the complaint on 21 April 2015 to publish a response. It has now done so.
Here is an extract from its press release:
In its investigation the CMA found examples of pricing and promotional practices that have the potential to confuse or mislead consumers and which could be in breach of consumer law. Where there is evidence of breaches of consumer law this could lead to enforcement action.
However, it has concluded that these problems are not occurring in large numbers across the whole sector and that generally retailers are taking compliance seriously to avoid such problems occurring. The CMA also found that more could be done to reduce the complexity in unit pricing to make it a more useful comparison tool for consumers. …Nisha Arora, CMA Senior Director, Consumer, said:
‘We have found that, whilst supermarkets want to comply with the law and shoppers enjoy a wide range of choices, with an estimated 40% of grocery spending being on items on promotion, there are still areas of poor practice that could confuse or mislead shoppers. So we are recommending further action to improve compliance and ensure that shoppers have clear, accurate information.
Although the CMA believes that misleading pricing is not as widespread as consumer groups have claimed,
in some cases the supermarkets could be fined. The CMA also says that it will work with the supermarkets to eliminate misleading information in promotions.
In addition it recommends that the Department for Business, Innovation and Skills (BIS) publishes guidelines for supermarkets on displaying unit prices in a consistent way. It also recommends that legislation should be simplified on how items should be unit-priced.
The following articles look at the implications of the CMS’ findings.

With worries about Greek exit from the eurozone, with the unlikelihood of further quantitative easing in the USA and the UK, with interest rates likely to rise in the medium term, and with Chinese growth predicted to be more moderate, many market analysts are forecasting that stock markets are likely to fall in the near future. Indeed, markets are already down over the past few weeks. Since late April/early May, the FTSE is down 4.5%; the German DAX index is down 7.0%; the French CAC40 index is down 6.9%; and the US Dow Jones index is down 2.3%. But does this give us an indication of what is likely to happen over the coming months?
If stock markets were perfectly efficient, then all possible information about the future will already have been taken into account and will all be reflected in current share prices. It would be impossible to ‘get ahead of the game’.
It is only if market participants have imperfect information and if you have better information than other people that you can are likely to predict correctly what will happen. Even then, the markets might be buffeted by random and hence unpredictable shocks.
Some people correctly predicted things in the past: such as crashes or booms. But in many cases, this was luck and their subsequent predictions have proved to be wrong. When financial advisers or newspaper columnists give advice, they are often wrong. If they were reliably right, then people would follow their advice and markets would rapidly adjust to their predictions.
If Greece were definitely to exit the euro, if interest rates were definitely to rise in the near future, if it became generally believed that stock markets were overvalued, then stock markets would probably fall. But these things may not happen. After all, people have been predicting a rise in interest rates from their ultra-low levels for many months – and it hasn’t happened yet, and may not happen for some time to come – but it may!
If you want to buy shares, you might just as well buy them at random – or randomly sell any you already have. As Tetlock says, quoted in the Nasdaq article:
“Even the most astute observers will fail to outperform random prediction generators – the functional equivalent of dart-throwing chimps.”
And yet, people do believe that they can predict what is going to happen to stock markets – if not precisely, then at least roughly. Are they deluded, or can looking calmly at likely political and economic events put them one step ahead of other people who perhaps behave more reactively and emotionally?

Questions
- Why may a return of rising interest rates lead to a ‘meltdown in equity prices’? Why might it not?

- Is there an asymmetry between buying and selling behaviour in stock markets?
- Will ignoring stock market forecasts make people better investors?
- “The stock market prices suggest that investors believe both the Federal Reserve and the Bank of England are bluffing about raising interest rates. That may be so, but it is an extremely risky game of chicken for investors to play.” Explain and discuss.
Economics is about choices. But how can people be persuaded to make healthy choices, or socially responsible or environmentally friendly choices? Behavioural economists have studied how people can be ‘nudged’ into changing their behaviour. One version of nudge theory is ‘fun theory’. This studies how people can be persuaded into doing desirable things by making it fun to do so.
I came across the first video below a couple of days ago. It looks at a highly successful experiment at the Odenplan underground station in Stockholm to persuade people to make the healthy choice of using the stairs rather than the escalator. It made doing so fun. The stairs were turned into a musical keyboard, complete with sound. Each stair plays a piano note corresponding to its piano key each time someone treads on it. As you go up the stairs you play an ascending scale.
After installing the musical staircase, 66% more people than normal chose the stairs over the escalator.
The fun theory initiative is sponsored by Volkswagen. The Fun Theory website is ‘dedicated to the thought that something as simple as fun is the easiest way to change people’s behaviour for the better. Be it for yourself, for the environment, or for something entirely different, the only thing that matters is that it’s change for the better.’
VW held a competition in 2009 to encourage people to invent fun products designed to change people’s behaviour. There were over 700 entries and you can see them listed on the site. The 13 finalists included the musical staircase, traffic lights with quiz questions on the red, a Connect Four beer crate, fun tram tickets (giving entry to an instant-win lottery), a pinball exercise machine, a speed camera lottery where a winner is chosen from those abiding by the speed limit, a jukebox rubbish bin (which plays when people add rubbish), a one-armed vending machine, a fun doormat, car safety belts linked to a car’s entertainment system, car safety belt with a gaming screen which turns on when buckled, a bottle bank arcade system and the world’s deepest bin (or at least one which sounds as if it is). The winner was the speed camera lottery.

- Other than through having fun, how else may people be nudged into changing their behaviour?
- Go through some of the entries to the Fun Theory Award and choose three that you particularly like. Explain why.
- Invent your own fun theory product. You might do this by discussing it groups and perhaps having a group competition.
How important are emotions when you go shopping? Many people go shopping when they ‘need’ to buy something, whether it be a new outfit, food/drink, a new DVD release, a gift, etc. Others, of course, simply go window shopping, often with no intention of buying. However, everyone at some point has made a so-called ‘impulse’ purchase.
There is only one article below, which is from the BBC and draws on data released from the National Employment Savings Trust’s survey. This report suggests that British people spend over £1 billion every year on impulse buys – purchases that are not needed, were not intended and are often regretted once the ‘high’ has worn off. Often, it is the way in which a product is advertised or positioned that leads to a spontaneous purchase – seeing chocolate bars/sweets at the tills; a product offered at a huge discount advertised in the window of a shop; 2 for 1 purchases; points for loyalty etc. All of these and more are simple techniques used by retailers to encourage the impulse buy. As consumer psychologist, Dr. James Intriligator says:
Retailers have clever ways of manipulating customers to spend more but if you stick to your plans you can avoid being affected by their tactics.

In other cases, it’s simply the frame of mind of the consumer that can lead to such purchases, such as being hungry when you’re food shopping or having an event to attend the next day and deciding to go window shopping, despite already having something to wear! Dr. Intriligator continues, saying:
Your ability to resist and make rational choices is diminished when your glucose levels are down … When you get irrational, you fall back on trusted brands, which often leads you to spend more money … Later in the shop, you’re more tired and less likely to resist [impulse buys]
But are such purchases irrational? One of the key assumptions made by economists (at least in traditional economics) is that consumers are rational. This implies that consumers weigh up marginal costs and benefits when making a decision, such as deciding whether or not to purchase a product. But, do impulse buys move away from this rational consumer approach? Is buying something because it makes you happy in the short term a rational decision? Behavioural economics is a relatively new ‘branch’ of economics that takes a closer look at the decisions of consumers and what’s behind their behaviour. The following article from the BBC considers the impulse buy and leaves you to consider the question of irrational consumers.
