The rate of inflation in the UK is measured using the Consumer Prices Index (CPI). This is made up of a basket of goods and the ONS updates this ‘basket’ each year to ensure it is representative of what the average UK household buys. The basket contains 703 items, with 110,000 individual prices collected each month.

In past years, items such as lip gloss have been added to the basket of goods, together with tablet computers and teenage fiction. In the recent update by the ONS, e-cigarettes have been added, together with specialist ‘craft’ beers and music streaming. On the other hand, other items have been removed, as the world changes. For example, during the recession, champagne was removed as an item that the representative household was no longer buying. In other cases, items are removed as they become outdated or obsolete with technology changing. This is the case with satellite navigation systems. As people turn to using their smartphones to navigate their way from A to B, satellite navigation systems are no longer seen as an item bought by the representative household.

The UK inflation rate is at an all-time low of 0.3% and there have been concerns that it may become negative, meaning we enter the world of deflation. However, if this does occur, many suggest that it is not bad deflation, as it is being driven by the extremely low oil prices. No matter what the inflation rate, the ONS will always continue to update the basket of goods that calculates inflation. It is therefore essential that these changes are made each year, as consumer buying habits do fluctuate considerably, as income changes, technology changes and general tastes change. The following articles consider what’s in and what’s out.

Questions

  1. What is the difference between the CPI and RPI? Which is usually higher? Explain your answer.
  2. Explain why champagne was removed from the basket of goods during the recession. What is sensible?
  3. How is the CPI calculated and hence how is inflation measured?
  4. Why has there been a movement towards chilled pizzas and away from frozen pizzas? Is the change likely to affect their relative price? Use a diagram to support your answer.
  5. What impact has technological progress had on the basket of goods that the representative household purchases? Do you think that technological progress make it more or less important for the basket of goods to be reviewed annually?
  6. Do you think products such as the iPad and e-cigarettes should be included in the CPI? Are they truly representative?
  7. In the BBC News article, you can access a list of the products that are ‘in and out’. Is there anything on there that you think should be in or that should be out? Be sure to justify your answer!

Many important economic changes have occurred over the past two years and many have occurred in the past two months. Almost all economic events create winners and losers and that is no different for the Russian economy and the Russian population.

There is an interesting article plus videos on the BBC News website (see link below), which consider some of the economic events that, directly or indirectly, have had an impact on Russia: the fall in oil prices; the conflict between Russia and the Ukraine; the fall in the value of the rouble (see chart); the sanctions imposed by the West.

Clearly there are some very large links between events, but an interesting question concerns the impact they have had on the everyday Russian consumer and business. Economic growth in Russia has been adversely affected and estimates suggest that the economy will shrink further over the coming year. Oil and gas prices have declined significantly and while this is good news for many consumers across the world, it brings much sadder tidings for an economy, such as Russia, that is so dependent on oil exports.

However, is there a bright side to the sanctions or the falling currency? The BBC News article considers the winners and losers in Russia, including families struggling to feed their families following spending cuts and businesses benefiting from less competition.

Questions

  1. Why has the rouble fallen in value? Use a demand and supply diagram to illustrate this.
  2. What does a cheap rouble mean for exporters and importers within Russia and within countries such as the UK or US?
  3. One of the businesses described in the article explain how the sanctions have helped. What is the explanation and can the effects be seen as being in the consumer’s interest?
  4. Oil prices have fallen significantly over the past few months. Why is this so detrimental to Russia?
  5. What is the link between the exchange rate and inflation?

Oil prices have been plummeting in recent months. Indeed, many commentators are saying that this is the major economics news story of 2014. In June 2014 Brent crude was around $112 per barrel. By December the price has fallen to around $60 – a fall of 46%. But what are the implications for fuel prices?

Just because the crude oil price has fallen by 46%, this does not mean that prices at the pump should do the same. Oil is priced in dollars and the pound has depreciated against the dollar by just over 7% since June, from around £1 = $1.69 to around £1 = $1.57. Thus in sterling terms, crude oil has fallen by only 42%.

More significantly, the cost of crude is a relatively small percentage of the price of a litre of petrol. At a price of 132p per litre (the July average price), crude accounted for around 27% of the price, or around 36p per litre. At a price of 114p per litre, the price in late December, crude accounts for around 19% of the price, or around 21.5p per litre. The largest element of price is fuel duty, which is charged at a flat rate of 57.95p per litre. In addition there is VAT at 20% of the pre-VAT price (or 16.67% of the retail price). Finally there are the refining, distribution and retail costs and margins, but these together account for only around 16p per litre.

What this means is that the 46% cut in oil prices has led to a cut in petrol prices of only around 14%. If petrol prices were to reach £1 per litre, as some commentators have forecast, crude oil prices would have to fall to under $40 per barrel.

Although petrol and diesel prices have fallen by a smaller percentage than oil prices, this still represents a significant cut in motoring and transport costs. It also represents a significant cut in costs for the petrochemical industry and other industries using large amounts of oil.

For oil-importing countries this is good news as the fall in the oil price represents an increase in real incomes. For oil importing countries, and especially those such as Russia and some OPEC countries where oil constitutes a large proportion of their exports, it is bad news. We explore these effects in Part 2.

Questions

  1. Why does the price of petrol fluctuate less in percentage terms than the price of crude oil?
  2. What factors will affect whether UK petrol prices fall to £1 per litre?
  3. If crude oil prices fell by 20%, in which of these two cases would there be a bigger percentage fall in petrol prices: (a) petrol price currently 140p; (b) petrol price currently 110p? Explain.
  4. Distinguish between a specific tax and an ad valorem tax. Which of these is (a) fuel duty; (b) VAT? Illustrate your answer with a supply and demand diagram.
  5. What determines the price elasticity of demand for petrol and diesel? Is the long-run elasticity likely to be higher or lower than the short-run elasticity? Explain.
  6. Distinguish between demand-pull and cost-push inflation. Given that oil price changes are correlated to inflation, would you characterise recent falls in inflation as reductions in demand-pull or cost-push pressures, or both: (a) in a specific oil-importing country; (b) globally?

Figures for employment and unemployment give an incomplete picture of the state of the labour market. Just because a person is employed, that does not mean that they are working the number of hours they would like.

Some people would like to work more hours, either by working more hours in their current job, or by switching to an alternative job with more hours or by taking on an additional part-time job. Such people are classed as ‘underemployed’. On average, underemployed workers wanted to work an additional 11.3 hours per week in 2014 Q2. Underemployment is a measure of slack in the labour market, but it is not picked up in the unemployment statistics.

Other people would like to work fewer hours (at the same hourly rate), but feel they have no choice – usually because their employer demands that they work long hours. Some, however, would like to change to another job with fewer hours even if it involved less pay. People willing to sacrifice pay in order to work fewer hours are classed as ‘overemployed’.

Statistics released by the Office for National Statistics show that, in April to June 2014, 9.9%, or 3.0 million, workers in the UK were underemployed; and 9.7%, or 2.9 million, were overemployed.

The figures for underemployment vary between different groups:

11.0% of female workers 8.9% of male workers
19.6% of 16-24 year olds 9.9% of all workers
21.1% of people in elementary occupations (e.g. cleaners, shop assistants and security guards) 5.4% of people in professional occupations (e.g. doctors, teachers and accountants)
11.5% of people in the North East of England (in 2013) 9.2% of people in the East of England (in 2013)
22.1% of part-time workers 5.4% of full-time workers

As far as the overemployed are concerned, professional people and older people are more likely want shorter hours

The ONS data also show how under- and overemployment have changed over time: see chart (click here for a PowerPoint). Before the financial crisis and recession, overemployment exceeded underemployment. After the crisis, the position reversed: underemployment rose from 6.8% in 2007 to a peak of 10.8% in mid-2012; while overemployment fell from 10.5% in 2007 to a trough of 8.8% in early 2013.

More recently, as the economy has grown more strongly, underemployment has fallen back to 9.9% (in 2014 Q2) and overemployment has risen to 9.7%, virtually closing the gap between the two.

The fact that there is still significant underemployment suggests that there is still considerable slack in the labour market and that this may be acting as a brake on wage increases. On the other hand, the large numbers of people who consider themselves overemployed, especially among the professions and older workers, suggests that many people feel that they have not got the right work–life balance and many may be suffering consequent high levels of stress.

The articles linked below look at the dangers of deflation and policies of central banks to counter it.

Deflation in economics has three meanings. The first is falling prices: i.e. negative inflation. The second, more traditional meaning, is a fall in real aggregate demand, resulting in lower output, higher unemployment and lower inflation – and quite possibly an actual fall in the price level. These first two definitions describe what is generally seen as an undesirable situation. The third is a slowing down in the growth of real aggregate demand, perhaps as a result of a deliberate act of fiscal and/or monetary policy. This third meaning could describe a desirable situation, where unsustainable growth is reduced and inflation is reduced from an above-target level.

Here we focus on the first definition. The first two articles look at the dangers of a fall in the price level. The chart below shows falling inflation, although not actually deflation, in China, France, Germany and the UK (click here for a PowerPoint). Several European countries, however, are experiencing actual deflation. These include: Greece, Spain, Hungary, Poland and Sweden. Inflation in the eurozone for 2014 is expected to be a mere 0.5%.

The most obvious danger of deflation (or expected deflation) is that people will delay spending on durable goods, such as cars, furniture and equipment, hoping to buy the items cheaper later. The result could be a fall in aggregate demand and a fall in output and employment.

For retailers, this is all spelling Christmas doom. Already the runup to the most crucial time of the year for shops is being characterised by a game of chicken. Shoppers are wondering how long they can leave their festive buying in the hope of late bargains.

Interest rates may be low, but for people with debts, this is being offset by the fact that inflation is no longer reducing the real value of that debt. For people with credit card debt, personal loans and most mortgages, the interest rate they pay is significantly above the rate of inflation. In other words, the real interest rate on their debt is still significantly positive. This may well discourage people from borrowing and spending, further dampening aggregate demand. And, with a Bank Rate of just 0.5%, there is virtually no scope for lowering the official interest rate further.

At least in the UK, economic growth is now positive – for the time being at any rate. The danger is becoming more serious, however, in many eurozone countries, which are already back in recession or close to being so. The ECB, despite its tentative steps to ease credit conditions, it moving closer to the day when it announces full-blown quantitative easing and buys sovereign bonds of eurozone countries. The Bank of Japan has already announced that it is stepping up it QE programme – a vital ingredient in getting Abenomics back on track and pulling Japan out of its latest recession.

In the USA, by contrast, there is little danger of deflation, as the US economy continues to grow strongly. The downside of this, has been a large rise in consumer debt (but not mortgages) – the ingredients of a possible future bubble and even a new financial crisis.

Questions

  1. What are (a) the desirable and (b) the undesirable consequences of deflation? Does the answer depend on how deflation is defined?
  2. What is meant by a ‘deflationary gap’? In what sense is ‘deflationary’ being used in this term?
  3. Why have oil prices been falling? How desirable are these falls for the global economy?
  4. Is there an optimal rate of inflation? If so, how would this rate be determined?
  5. The chart shows that inflation in Japan is likely to have risen in 2014. This in large part is the result to a rise in the sales tax earlier this year. If there is no further rise in the sales tax, which there will probably not be if Mr Abe’s party wins the recently called election, what is likely to be the effect of the 2014 tax rise on inflation in 2015?
  6. If the Bank Rate is below the rate of inflation, why are people facing a positive real rate of interest? Does this apply equally to borrowers and savers?
  7. In what sense is there a cultural revolution at the Bank of England?
