Inflation is measured as the percentage increase in the Consumer Prices Index (CPI) over the previous 12 months. The index is constructed from a basket of goods that is supposed to represent the buying habits of an average UK household. This basket is updated each year as tastes change and as technology moves forward. The basket contains approximately 700 items, with 180,000 individual prices collected each month.
As certain goods become more popular and trends change, the ONS have the responsibility of identifying these changes and updating the basket of goods. The CPI then looks at how the weighted average price of this basket of goods changes from one month to the next. As the CPI gives us the main measure of UK inflation, it is essential that the basket of goods used does represent current consumer demands. If the basket of goods used 20 years ago was still in place, we wouldn’t see thing like mobile phones and ipads being included. This is one sector that has seen significant growth in recent years and the basket of goods has been adapted in response. A new addition to the measure is e-books, which have seen a significant growth in popularity.
However, just as new products have been added to the CPI measure, other goods have been removed. In the most recent update, we’ve seen the removal of champagne and Freeview boxes from the basket of goods. With rapid changes in technological products, such as the ipad, kindle and e-books, products that were new additions only a few years ago are now old news, being replaced by the latest gadgets. Other changes to the basket of goods are less about reflecting consumer trends and more about making certain categories more representative, such as fruits and hot drinks.
So, can the changes in the basket of goods tell us anything about the impact of the recession on buying habits? One notable exclusion from the basket of goods is champagne sold in restaurants and bars. In an economic downturn, you’d expect luxury products to see a decline in consumption and the trend in champagne consumption certainly seems to support the theory. The trends suggest that consumers have instead switched to cheaper alternatives, with things like white rum bought from shops increasing.
Many people may look at the basket of goods and think that it doesn’t reflect what you buy in your average shop. But, the purpose of the CPI is to try to reflect the average consumer and the different items in the basket are given different weightings to give some indication of the amount spent on each good. The articles below look at the changes in the CPI basket of goods and what, if anything, we can take from it.

Recent figures from the ONS suggest that the UK lags well behind its competitors in terms of labour productivity. In terms of output per hour worked, Germany produces 22% more than the UK, France produces 26% more, the USA produces 27% more, the Netherlands 31% more and Ireland 43% more. The first chart illustrates some of these figures.
(Click here for a PowerPoint of this chart.)
And in the past few years the problem has been getting worse. This is shown in the second chart. This, however, is a relatively recent phenomenon. Until 2006, the gap was narrowing, but since then it has widened. (Click here for a PowerPoint of the second chart.)
What has caused this widening of the gap? Part of the problem is a historical lack of investment in the UK. Between 2005 and 2012, the UK invested on average 15.7% of GDP. The USA invested 16.5%, Germany 17.9% and France 20.1%. And part of the problem has been the cut back in private-sector investment in response to the recession (which has been deeper in the UK) and in public-sector investment as part of the government’s austerity measures.
Part of the problem has been lower levels of inward investment. Inward direct investment to the UK in 2011 was only 24 per cent of that in 2007. In France, Germany, Italy and the USA, the figures were 43, 50, 66 and 105 per cent respectively.
Part of the problem has been the size of the financial sector in the UK. This is considerably larger as a proportion of the economy than in most the UK’s major competitors. And it was this sector most hard hit by the crisis of 2007/8.
With this poor productivity performance, you might expect unemployment to have soared. In fact, the UK has one of the lowest unemployment rates of the developed countries and in recent months it has been falling while other countries have seen their unemployment rates rise.
In fact, low productivity and high employment are compatible. If people produce less than their counterparts abroad, then more people will be needed to produce the same level of output. The problem, of course, is that this only works if wages are kept down. Indeed, wages have fallen in real terms and now stand at the level of 10 years ago.
The problem of falling real wages is that this translates into a lack of demand – especially when people are trying to reduce their debts. Not only does this result in a lack of economic growth, it discourages firms from investing – and investment is one of the prime drivers of future productivity growth!
The following articles explore the problem of low productivity and its relationship with employment and with both short-term and long-term economic growth.

Each year world political and business leaders meet at the World Economic Forum in the Swiss resort of Davos. The aim is to assess the progress of the global economy and to look at challenges ahead and what can be done about them.
Cynics claim that the round of presentations, discussions, Champagne receptions and fine dining rarely leads to anything concrete. Those who are less cynical argue that the Forum gives a unique opportunity for considering policy options and helping to shape a global consensus.
This year the mood was more optimistic. Many believe that the worst of the financial crisis is behind us. Stock markets are buoyant; the banking system seems more secure; the eurozone has not collapsed; growth prospects seem a little brighter.
But perhaps ‘optimistic’ is an overstatement. ‘Less pessimistic’ might be a better description. As Christine Lagarde, head of the IMF, pointed out in her speech:
The recovery is still weak, and uncertainty is still high. As the IMF announced just a few hours ago in our World Economic Outlook, we expect global growth of only 3½ percent this year, not much higher than last year. The short-term pressures might have alleviated, but the longer-term pressures are still with us. (Click here for transcript).
In both her speech and her press conference, she went on to outline the policies the IMF feels should be adopted to achieve sustained global growth.
The articles below summarise the outcomes of the Forum and some of the views expressed.

Questions
- Why was the mood at the WEF less pessimistic than in 2012?
- What threats remain to sustained global recovery?
- What policies are being recommended by Christine Lagarde of the IMF? Explain the reasoning behind the recommendations.
- What disagreements are there between global leaders on the scope for fiscal and monetary policies to stimulate economic growth?
- In her press conference, Christine Lagarde stated that “the teams here have concluded that the fiscal multipliers were higher in the context of that unbelievable international crisis”. Do you agree with this statement? Explain.
What lies ahead for economic growth in 2013 and beyond? And what policies should governments adopt to aid recovery? These are questions examined in four very different articles from The Guardian.
The first is by Nouriel Roubini, Professor of Economics at New York University’s Stern School of Business. He was one of the few economists to predict the collapse of the housing market in the USA in 2007 and the credit crunch and global recession that followed. He argues that continuing attempts by banks, governments and individuals to reduce debt and leverage will mean that the advanced economies will struggle to achieve an average rate of economic growth of 1%. He also identifies a number of other risks to the global economy.
In contrast to Roubini, who predicts that ‘stagnation and outright recession – exacerbated by front-loaded fiscal austerity, a strong euro and an ongoing credit crunch – remain Europe’s norm’, Christine Lagarde, head of the IMF and former French Finance Minister, predicts that the eurozone will return to growth. ‘It’s clearly the case’, she says, ‘that investors are returning to the eurozone, and resuming confidence in that market.’ Her views are echoed by world leaders meeting at the World Economic Forum in Davos, Switzerland, who are generally optimistic about prospects for economic recovery in the eurozone.
The third article, by Aditya Chakrabortty, economics leader writer for The Guardian, looks at the policies advocated at the end of World War II by the Polish economist, Michael Kalecki and argues that such policies are relevant today. Rather than responding to high deficits and debt by adopting tough fiscal austerity measures, governments should adopt expansionary fiscal policy, targeted at expanding infrastructure and increasing capacity in the economy. That would have an expansionary effect on both aggregate demand and aggregate supply. Sticking with austerity will result in continuing recession and the ‘the transfer of wealth and power into ever fewer hands.’
But while in the UK and the eurozone austerity policies are taking hold, the new government in Japan is adopting a sharply expansionary mix of fiscal and monetary policies – much as Kalecki would have advocated. The Bank of Japan will engage in large-scale quantitative easing, which will become an open-ended commitment in 2014, and is raising its inflation target from 1% to 2%. Meanwhile the Japanese government has decided to raise government spending on infrastructure and other government projects.
So – a range of analyses and policies for you to think about!

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.
