At least once a year The Economist publishes its ‘hamburger standard’ exchange rates for currencies. It is a light-hearted attempt to see if currencies are exchanging at their purchasing-power parity rates. The test is the price at which a ‘Big Mac’ McDonald’s hamburger sells in different countries!
According to this simplified version of the purchasing-power parity theory, exchange rates should adjust so that a Big Mac costs the same in dollars everywhere (see Economics 8th edition Box 25.4).
These Big Mac exchange rates can be used to compare various prices and incomes between countries. The article linked below from The Guardian compares minimum wages between European countries in Big Mac terms.
There are 25 countries across Europe which have minimum wages. A clear pattern of minimum wage rates can be seen: although actual exchange rates understate the purchasing power of incomes in poorer European countries compared to richer ones, minimum wages, even in purchasing-power standard terms, are still higher in the richer countries.
Luxembourg’s minimum wage buys you just about three Big Macs in an hour, while most of northern Europe (and France) between 2–2.5 Big Macs. Moving south, the minimum wage nets about one Big Mac an hour. As we progress east, it begins to cost more than an hour of work on the minimum wage in order to afford a Big Mac.
Of course, there are other factors determining the dollar price of a Big Mac other than the failure of exchange rates to reflect purchasing-power parities. Nevertheless, using the Big Mac index in this way does give a useful preliminary snap shot of differences in what minimum wages can buy in different countries.

The linked article below from The Guardian paints a disturbing picture of the long-term problem of servicing both private-sector and public-sector debts.
With interest rates at historical lows, the problem has been masked for the time being. But with interest rates set to rise within a few months, and significantly over the coming years, the burden of debt servicing is likely to become severe. This could have profound effects both on long-term economic growth and on the distribution of income.
As the author, Phillip Inman states:
The funding gap is growing and with deficits on so many fronts, it is hard to see how promises to pensioners and health service users can be met without a dash for growth that is unsustainable, a switch to dramatic cost-cutting in other areas or higher taxes on those who came through the recession relatively unscathed.
You are probably facing the problem of growing debt yourself. How long, if ever, will it take you to repay your student loans? What impact will this have on your ability to spend and to have a ‘decent’ standard of living? Will you be able to afford a mortgage large enough to buy a reasonable house or flat? Will you be able to afford to do a masters degree or PhD without support from your parents or relatives or without a scholarship? And even if you manage to secure a well-paid job, will you be able to afford a reasonable pension for when you eventually retire?
The article looks at the nature of the problem and its causes. It concludes by saying:
Britain has become expert at putting off decisions and hoping for something to turn up. Without a return to ultra-cheap commodities, another technological/productivity revolution, or a return to more modest living and delayed gratification, it’s a plan that is running out of time.

The ONS has just released its annual publication, The Effects of Taxes and Benefits on Household Income. The report gives data for the financial year 2012/13 and historical data from 1977 to 2012/13.
The publication looks at the distribution of income both before and after taxes and benefits. It divides the population into five and ten equal-sized groups by household income (quintiles and deciles) and shows the distribution of income between these groups. It also looks at distribution within specific categories of the population, such as non-retired and retired households and different types of household composition.
The data show that the richest fifth of households had an average pre-tax-and-benefit income of £81,284 in 2012/13, 14.7 times greater than average of £5536 for the poorest fifth. The richest tenth had an average pre-tax-and-benefit income of £104,940, 27.1 times greater than the average of £3875 for the poorest tenth.
After the receipt of cash benefits, these gaps narrow to 6.6 and 11.0 times respectively. When the effect of direct taxes are included (giving ‘disposable income’), the gaps narrow further to 5.6 and 9.3 times respectively. However, when indirect taxes are also included, the gaps widen again to 6.9 and 13.6 times.
This shows that although direct taxes are progressive between bottom and top quintiles and deciles, indirect taxes are so regressive that the overall effect of taxes is regressive. In fact, the richest fifth paid 35.1% of their income in tax, whereas the poorest fifth paid 37.4%.
Taking the period from 1977 to 2012/13, inequality of disposable income (i.e. income after direct taxes and cash benefits) increased from 1977 to 1988, especially during the second two Thatcher governments (1983 to 1990) (see chart opposite). But then in the first part of the 1990s inequality fell, only to rise again in the late 1990s and early 2000s. However, with the Labour government giving greater cash benefits for the poor, inequality reduced once more, only to widen again in the boom running up to the banking crisis of 2007/8. But then, with recession taking hold, the incomes of many top earners fell and automatic stabilisers helped protect the incomes of the poor. Inequality consequently fell. But with the capping of benefit increases and a rise in incomes of many top earners as the economy recovers, so inequality is beginning to rise once more – in 2012/13, the Gini coefficient rose to 0.332 from 0.323 the previous year.
As far as income after cash benefits and both direct and indirect taxes is concerned, the average income of the richest quintile relative to that of the poorest quintile rose from 7.2 in 2002/3 to 7.6 in 2007/8 and then fell to 6.9 in 2012/13.
Other headlines in the report include:
Since the start of the economic downturn in 2007/08, the average disposable income has decreased for the richest fifth of households but increased for the poorest fifth.
Cash benefits made up over half (56.4%) of the gross income of the poorest fifth of households, compared with 3.2% of the richest fifth, in 2012/13.
The average disposable income in 2012/13 was unchanged from 2011/12, but it remains lower than at the start of the economic downturn, with equivalised disposable income falling by £1200 since 2007/08 in real terms. The fall in income has been largest for the richest fifth of households (5.2%). In contrast, after accounting for inflation and household composition, the average income for the poorest fifth has grown over this period (3.5%).
This is clearly a mixed picture in terms of whether the UK is becoming more or less equal. Politicians will, no doubt, ‘cherry pick’ the data that suit their political position. In general, the government will present a good news story and the opposition a bad news one. As economists, it is hoped that you can take a dispassionate look at the data and attempt to relate the figures to policies and events.

We have had a minimum wage in the UK for well over a decade and one its key purposes was to boost the pay of the lowest paid workers and in doing so reduce the inequality gap. Rising inequality has been a concern for many countries across the world and not even the nations with the most comprehensive welfare states have been immune.
Switzerland, known for its banking sector, has been very democratic in its approach to pay, holding three referenda in recent years to give the Swiss public the chance to decide on pay. Imposing restrictions on the bonuses available to the bosses of the largest companies was backed in the first referendum, but in this latest vote, the world’s highest minimum wage has been rejected. The proposed wage is the equivalent of £15 per hour and it is the hourly wage which proponents argue is the wage
needed to ensure workers can afford to ‘live a decent life’. However, prices in Switzerland are considerably higher than those in the UK and this wage translates to around £8.33 per hour in purchasing power parity terms, according to the OECD. In the UK, much debate has surrounded the question of a living wage and the impact that a significant increase in the NMW would have on firms. The concern in Switzerland has been of a similar nature.
With a higher wage, costs of production will inevitably rise and this is likely to lead to firms taking on fewer workers and perhaps moving towards a different mix of factors of production. With less workers being employed, unemployment would be likely to increase and it may be that the higher costs of production are passed onto consumers in the form of a higher price. One problem is that as prices rise, the real wage falls. Therefore, while advocates of this high minimum wage suggest that it would help to reduce the gap between rich and poor, the critics suggest that it may lead to higher unemployment and would actually harm the lowest paid workers. It appears that the Swiss population agreed with the critics, when 76% voted against the proposal. Cristina Gaggini, who is the Director of the Geneva Office of the Swiss Business Association said:
I think [it would have been] an own goal, for workers as well as for small companies in Switzerland … Studies show that a minimum wage can lead to much more unemployment and poverty than it helps people … And for very small companies it would be very problematic to afford such a high salary.
The proposal was made by Swiss Unions, given the high cost of living in Switzerland’s suggest cities. It was rejected by the Swiss Business Federation and government and this was then echoed by the overwhelming majority in the referendum. Switzerland has been found to be the most expensive place to live in the world and the wages paid are insufficient to provide a decent life, with many claiming benefits to support their earnings. The debate over the minimum wage and the living wage will continue in countries across the world, but for now the Swiss people have had their say. The following articles consider this issue.

On my commute to work on the 6th May, I happened to listen to a programme on BBC radio 4, which provided some fascinating discussion on a variety of economic issues. Technological change is constant and unstoppable and the consequences of it are likely to be both good and bad.
In this programme some top economists, including Joseph Stiglitz offer their analysis of the impact of technology and how the future might look, by considering a range of factors, such as youth unemployment, the productivity of labour, education, pensions and inequality. The benefits of new technology can be seen as endless, but the impact on inequality and how the benefits of technology are being distributed is a concern for many people. The best introduction to the programme and its content is simply to reproduce the description provided by BBC radio 4.
The baby boom generation came of age when it was accepted knowledge that innovation and productivity would always lead to higher standards of living. The generations which followed assumed this truth would continue into the future indefinitely. With the crash of 2008 the upward mobility the middle classes assumed was their right evaporated, and it is unlikely to return.
Martin Wolf, chief economics commentator of the Financial Times, asks how the work force of the future will be changed by the advancements of technologies. How should governments respond to a jobs market which is hollowing out opportunities for traditional educated professions and how will rewards for innovation and income for labour be distributed without creating a society plagued by endemic inequality?
We will speak with optimists and pessimists on both sides of the argument to find out how the repercussions of these changes will affect the way we all live now and well into the future.
It is well worth listening to and provides some interesting insights as to what the future might look like, as the inevitable technological change continues. The link for the programme is below.
