The consumer prices index (CPI) is used by the government and the Bank of England for measuring the rate of inflation, and in the 12 months to March 2010 it rose by 3.4%. This figure was above the expected rate of 3.1% and well above the Bank of England’s target of 2%. The other major measure of consumer prices, the retail prices index (RPI) rose by even more – by 4.4%.

In order to recover from the recession, the UK economy needs to grow, but as demand begins to rise, this could put further upward pressure on inflation. There are a number of influencing factors that have caused the recent rise in inflation (see Too much of a push from costs but no pull from demand). Large rises in housing, fuel, transport, many household services and food were contributing factors. Many of these factors, however, are thought to be temporary, so it may not be too much of a problem.

And anyway, at least if inflation does continue to rise, it won’t be unexpected!

Questions

  1. Why might the Monetary Policy Committee have to restrict growth to keep inflation manageable?
  2. What are some of the causes of rising inflation? Why are expectations so important?
  3. How is the CPI calculated to measure inflation?
  4. Normally, during a recession, we would expect economic growth to be poor, but inflation to be low and stable. How can we explain both poor growth and rising inflation?
  5. “Investors know that the UK government has more to gain from an unexpected bout of inflation than almost any other economy.” Why is this?

’The steepest and longest recession of any developed country since World War II.’ This has been the case for Ireland, which has seen national income fall by 20% since 2007. Many countries across the globe have experienced pretty bad recessions, but what makes Ireland stand out is how it has been dealt with.

In the UK, the government has continued spending in a bid to stimulate the economy and to use Gordon Brown’s phrase from 2008, we have aimed to ‘spend our way out of recession’. Ireland, however, did not have that option. With too much borrowing, Ireland was unable to stimulate the economy and needed to cut its debts in order to maintain its credibility in the eurozone. Last year, significant cuts in government spending were accompanied by tax rises equal to 5% of GDP. Similar action is to be expected in the UK following the election, where popular benefits may have to be reduced, as transfer payments do account for the majority of government spending. Whoever is in government following the election will have some hard decisions to make and everyone will be affected. Read the article below and listen to the interview and think about what the UK can learn from Ireland.

Questions

  1. In the interview, Brian Lenihan said that the UK was expecting too much from the falling value of sterling. What was the UK expecting following significant depreciations in the value of sterling and why has that not happened?
  2. What is a deflationary spiral? Why has it caused Ireland’s public debt to rise so much?
  3. Why does Brian Lenihan argue that there are limits to how much taxes can be increased? What are diminishing returns to taxation?
  4. Would the UK be any better off had we joined the euro? What about other countries: would they have benefited had we joined the euro?

The OECD published its latest interim assessment of the world economy on April 7. This showed a world gradually bouncing back from recession, with growing GDP (albeit at variable speeds in different countries), rising industrial production, increasing business confidence, a stabilising of financial markets, an easing of credit conditions and yet continuing low inflation.

The UK is forecast to have an annualised rate of growth of GDP in quarter 2 of 3.1%. This is the second highest of the G7 countries, behind only Canada. This would seem like good news – an economic spring for the UK.

Despite continuing growth in the OECD countries, in most of them recovery is fragile. The OECD thus recommends caution in removing the stimulus measures adopted in most countries and hence caution in embarking on measures to cut public-sector deficits. As the report states:

Despite some encouraging signs on activity, the fragility of the recovery, a frail labour market and possible headwinds coming from financial markets underscore the need for caution in the removal of policy support. Central banks have already begun to rein in the exceptional liquidity stimulus injected during the recession. Further action in this area will need to be guided by financial conditions. The normalisation of policy interest rates should be carried out at a pace that will be contingent on the strength of the recovery in individual countries and the outlook for inflation beyond the near-term projection horizon. As for fiscal policy, the sharp increase in government indebtedness in the OECD area during the downturn calls for ambitious, clearly communicated medium-term consolidation programmes in many countries. Consolidation should start in 2011, or earlier where needed, and progress gradually so as not to undermine the incipient recovery.

Questions

  1. What are the main findings in the report?
  2. What are the policy implications of the findings?
  3. What are the implications of developments in financial markets? What are the possible ‘headwinds’?
  4. What factors could threaten the recovery of the UK economy?

As the global recession began to take hold during 2008, so many commodity prices plummeted. Oil prices fell from over $140 per barrel in mid July 2008 to around $35 per barrel by the end of the year (a mere quarter of the price just 6 months previously). From early 2009, however, prices started rising again and have continued to do so during 2010. By mid April 2010, the price of oil had risen to $85 per barrel.

And it’s not just oil prices that have been rising. The prices of metals such as copper, nickel and zinc have been soaring. Since the beginning of February 2010, copper prices have risen by 18%, zinc prices by 20% and nickel prices by 46%. As the article from the Independent states:

The Office for National Statistics said that the input price index for materials and fuels purchased by the manufacturing industry rose 10.1 per cent in the year to March and rose 3.6 per cent between February and March alone. The ONS added that prices of imported materials as a whole, including imported crude oil, rose 4.4 per cent between February and March.

Much of the explanation for this has been the global recovery. But while raw material prices have been rising, grain prices have been relatively steady and recently have fallen. So how can this be explained? The answer, as always with commodity prices, lies with demand and supply, as you will see when you read the following articles.

Questions

  1. Use supply and demand analysis to explain why raw material prices have risen so rapidly. Illustrate your answer with a diagram.
  2. Use supply and demand analysis to explain why grain prices have fallen. Again, illustrate your answer with a diagram.
  3. What is the significance of income elasticity of demand and price elasticities of demand and supply in explaining the price changes in questions 1 and 2?
  4. How would you estimate the likely effect of a 1% rise in (a) general raw material prices and (b) factory gate prices on the rate of consumer price inflation?
  5. Why has the price of petrol risen above the level of July 2008, given that oil prices now are only about 60% of those in 2008?
  6. Why has a rise in factory gate prices led to a rise in the sterling exchange rate?
  7. If inflation rises as a result of a rise in commodity prices, what type of inflation would this increase in inflation be? Does the answer depend on what caused the rise in commodity prices?

The Quarterly National Accounts from the Office for National Statistics (ONS) reveal that the output of the UK economy grew by 0.4% in the fourth quarter of 2009. This is another upward revision to the growth number for Q4; the first estimate put growth at 0.1% and the second estimate at 0.3%.

The ONS release also reported the value of the UK economy’s output in calendar year 2009. In the release, GDP in 2009 is estimated at £1.396 trillion. Now, this is what economists call the nominal estimate because it measures the economy’s output using the prevailing prices, e.g. in the case of output in 2009, the prices of 2009. Of course, the problem arises when we compare nominal GDP – or GDP at current prices – over time. If prices are changing how can we know whether the volume of output is actually rising or falling? Therefore, constant-price or real estimates are reported which aim to show what GDP would have been if prices had remained at their levels in some chosen year (the base year). The base year currently used in the UK is 2005.

If we look at nominal GDP estimates for the UK from 1948 up to 2008 we find that they rise each year. So, regardless of the fact that in some of these years output volumes fell, price rises (inflation) have been sufficient to cause nominal or current-price GDP to rise. But, this was not true in 2009!

But, why did nominal GDP fall in 2009? Well, firstly, the average price of the economy’s output, which is measured by the GDP deflator, rose by only 1.36% in 2009. This was the lowest rate of economy-wide inflation since 1999 (although real GDP or output rose by 3.9% in 1999). And, secondly, in 2009 output fell by 4.9%. The extent of the fall in output meant that price increases were not sufficient for nominal GDP to rise. In fact, the actual value of GDP in 2008 was £1.448 trillion as compared with £1.396 trillion in 2009. This means that nominal GDP fell by 3.6% in 2009. The next lowest recorded change, since comparable figures began in 1948, was actually in 2008 when nominal GDP rose by 3.5% (real GDP rose too in 2009, albeit by only 0.5%).

So, in short, the decline in both nominal and real GDP in 2009 indicates just how deep the economic downturn has been.

Questions

  1. Explain what you understand by the terms ‘nominal GDP’ and ‘real GDP’. Can you think of other examples of where economists might distinguish between nominal and real variables?
  2. Explain under what circumstances nominal GDP could rise despite the output of the economy falling.
  3. The average annual change in nominal GDP since 1948 is 8.2% while that for real GDP is 2.4%. What do you think we can learn from each of these figures about long-term economic growth in the UK?
  4. What do you understand to be the difference between short-term and long-run economic growth? Where, in the commentary above, is there reference to short-term growth?
