How the RPI might change…

Inflation is a key macroeconomic variable and governments typically aim for both low and stable rates of inflation. In the UK there are two main measures of the rate of inflation in the UK – the CPI and the RPI. Over the past few years there has been a growing gap between the two measures and this has led to consultations about how the RPI could be adapted to allow it to rise more slowly in the future. (Click here for a PowerPoint of the chart.)

The RPI and CPI measure inflation in different ways – they don’t measure the same basket of goods. The RPI measure includes the costs of housing, whereas the CPI does not include this. Furthermore, the RPI is an arithmetic mean and the CPI is a geometric mean, which will be lower than the arithmetic mean. The ONS says that a key advantage of using the geometric mean (i.e. the CPI) is that:

…it can better reflect changes in consumer spending patterns relative to changes in the price of goods and services.

Typically the RPI has been about 1% higher than the CPI and governments can benefit from this by linking state benefits to the CPI (the lower rate) and payments they receive to the RPI, thus maximising the difference between earnings and expenditure.

However, the gap between these two measures of inflation has been growing and this has been causing concern for the ONS and the Office for Budget Responsibility (OBR). This has led to the consultative process regarding making changes to the RPI. However, any change made to the RPI would put certain groups at a disadvantage. One such group is pensioners – many pensioners in the private sector have their pensions linked to the RPI and if a change were made to bring it more in line with the CPI (i.e. lower it) they would suffer. Ros Altman, director general of SAGA said:

After 30 years of retirement, someone who receives 0.6% lower inflation uprating will end up with a pension nearly 20% lower…Therefore, over time, pensioners will be able to afford less and less and pensioner poverty will increase once again.

There would be some beneficiaries of any change to the RPI – the government would benefit in some areas; company pension schemes might also see gains made; some students might benefit and even rail travellers.

An announcement was made by the National Statistician, Jil Matheson, on the 10 January. Much to the surprise of most experts, she has decided to keep the RPI measure unchanged. She did recommend, however, that a new index be introduced that would be published alongside RPI and CPI. The new index would better meet international standards.

The following articles look at the arguments for and against changing the RPI measure.

The 2 Ds of British recessions

We know two things about economic growth in a developed economy like the UK: it is positive over the longer term, but highly volatile in the short term. We can refer to these two facts as the twin characteristics of growth. The volatility of growth sees occasional recessions, i.e. two or more consecutive quarters of declining output. Since 1973, the UK has experienced six recessions.

Here we consider in a little more detail the growth numbers for the UK from the latest Quarterly National Accounts, focusing on the depth and duration of these six recessions. How do they compare?

The latest figures on British economic growth show that the UK economy grew by 0.9 per cent in the third quarter of 2012. However, when compared with the third quarter of 2011, output was essentially unchanged. This means that the annual rate of growth was zero. Perhaps even more telling is that output (real GDP) in Q3 2012 was still 3.0 per cent below its Q1 2008 level.

The chart helps to put the recent output numbers into an historical context. It shows both the quarter-to-quarter changes in real GDP (right-hand axis) and the level of output as measured by GDP at constant 2009 prices (left-hand axis). It captures nicely the twin characteristics of growth. Since 1970, the average rate of growth each quarter has been 0.6 per cent. This is equivalent to an average rate of growth of 2.35 per cent per year. The chart also allows us to pin-point periods of recessions.

One way of comparing recessions is to compare their ‘2 Ds’: depth and duration. The table shows the number of quarters each of the six recessions since 1973 lasted. It also shows how much smaller the economy was by the end of each recession. In other words, it shows the depth of each recession as measured by the percentage reduction in output (real GDP).

British recessions

Duration (quarters) Depth (output lost, %)
1973Q3–74Q1 3 3.25
1975Q2–75Q3 2 1.76
1980Q1–81Q1 5 4.63
1990Q3–91Q3 5 2.93
2008Q2–09Q2 5 6.28
2011Q4–12Q2 3 0.90

We can see that three of the recessions lasted for five quarters. In the case of the recessions starting in 1975 and 2011 they occurred very shortly after a previous recession. Hence, we observe two so-called double-dip recessions.

The table reveals that the deepest recession by some distance was that in the late 2000s. As a result of this recession, UK output declined by 6.3 per cent. As the recent GDP numbers show, the UK has yet to recover the ‘lost output’ that followed the financial crisis.

What does 2013 hold?

While the Western world has struggled with economic growth for the past 6 years, emerging economies such as China, Brazil and India have recorded some very high rates of growth. Throughout 2012, there were signs that these economies were not going to be the saviour of the global economy that we all thought. But, as we enter 2013, is it these economies that still hold the hope of the West for more positive figures and better economic times?

The article below from BBC News, in particular, considers the year ahead for the Asian economies and what it might mean for the Western world. Although these countries are by no means safeguarded against the impending approach of the US economy to their fiscal cliff or the ongoing eurozone crisis, they have seemed to be more insulated than the rest of the world. A crucial question to consider is whether this will continue. Furthermore, are the growth levels and policies of a country such as China sustainable? Can it continue to record such high growth rates in the face of the global economic situation?

The Japanese economy has been in serious trouble for a couple of decades, but measures to boost growth for this economy are expected. If these do occur, then western economies may feel some of their positive effects. At present, there is a degree of optimism as we enter the New Year, but how long this will last is anybody’s guess. The following articles consider the year ahead.

Should people be paid a ‘living wage’?

Pressure has been growing in the UK for people to be paid no less than a living wage. The Living Wage Foundation claims that this should be £8.55 per hour in London and £7.45 in the rest of the UK. The current minimum wage is £6.19.

There has been considerable support for a living wage across the political spectrum. Ed Miliband, the Labour leader, has stated that a Labour government would ensure that government employees were paid at least the living wage and that government contracts would go only to firms paying living wages. Other firms that paid less could be ‘named and shamed’. The living wage has also been supported by Boris Johnson, Conservative Mayor of London. The Prime Minister said that a living wage is ‘an idea whose time has come’, although many Conservatives oppose the idea.

The hourly living wage rate is calculated annually by the Centre for Research in Social Policy and is based on the basic cost of living. The London rate is calculated by the Greater London Authority.

Advocates of people being paid at least the living wage argue that not only would this help to reduce poverty, it would also help to reduce absenteeism and increase productivity by improving motivation and the quality of people’s work.

It would also bring in additional revenue to the government. According to a report by the Institute for Public Policy Research and the Resolution Foundation, if everyone were paid at least a living wage, this would increase the earnings of the low paid by some £6.5bn per year. Of this, some £3.6bn would go to the government in the form of higher income tax and national insurance payments and reduced spending on benefits and tax credits. Of this £6.5bn, an extra £1.3 billion would be paid to public-sector workers, leaving the Treasury with a net gain of £2.3bn.

But what would be the effect on employment? Would some firms be forced to reduce their workforce and by how much? Or would the boost to aggregate demand from extra consumer spending more than offset this and lead to a rise in employment?. The following articles look at the possible effects.

  2. Distinguish between absolute and relative poverty. Would people being paid below a living wage be best described as absolute or relative poverty (or both or neither)?
  3. What do you understand by the term ‘efficiency wage’? How is this concept relevant to the debate about the effects of firms paying a living wage?
  4. Under what circumstances would raising the statutory minimum wage rate to the living wage rate result in increased unemployment? How is the wage elasticity of demand for labour relevant to your answer and how would this elasticity be affected by all firms having to pay at least the living wage rate?
  5. What would be the macroeconomic effects of all workers being paid at least the living wage rate? What would determine the magnitude of these effects?

A new economic road for Japan?

Japan’s general election on 16 December was won by the centre-right Liberal Democratic Party (LDP), led by Shinzo Abe. It gained a two-thirds majority in the lower house. It returns to power after losing to the Democratic Party in 2009. Previously it had been in office for most of the time since 1955.

The LDP has promised to revive the flagging Japanese economy, which has been suffering from years of little or no growth and returned to recession last quarter. Economic confidence has been damaged by a dispute with China about the sovereignty over some small islands in the East China Sea. The economy, whose exports make up some 13% of GDP, has suffered from the global slowdown and a high yen. The yen has appreciated against the dollar by around 40% since 2007.

The economy has also suffered from the shutdown of all its nuclear reactors following the earthquake and tsunami last year. Nuclear power accounted for over 30% of the country’s electricity generation.

Mr Abe promises to revive the economy through fiscal and monetary policies. He plans a fiscal stimulus package in early 2013, with increased government expenditure on infrastructure and other public-works. He also wants the Bank of Japan to increase its inflation target from 1% to 3% and to achieve this through various forms of monetary easing.

The initial reactions of markets to the election result were favourable. The stock market rose and the yen fell.

However, as the following articles discuss, there are dangers associated with Mr Abe’s policies. The expansionary fiscal policy will lead to a rise in the country’s general-government debt, which, at some 240% of GDP, is by far the largest in the developed world. This could lead to a loss of confidence in Japanese debt and a fall in the price of bonds on the secondary markets and a rise in government borrowing costs. Also, a depreciation of the yen, while welcomed by exporters, would increase the price of imports, including food and raw materials.
