Wisdom of hindsight

Every quarter, the Bank of England publishes its Inflation Report. This analyses developments in the macroeconomy and gives forecasts for inflation and GDP growth over the following 12 quarters. It is on the forecast for inflation in 8 quarters’ time that the Bank of England’s Monetary Policy Committee primarily bases its interest rate decision.

According to the February 2011 Inflation Report forecast, CPI inflation is expected to be at or slightly below its 2% target in two year’s time, but there is considerable uncertainty about this, as shown in the fan diagram in Chart 3 of the Overview. What is more, inflation is likely to rise considerably before it falls back. As the Report states:

CPI inflation is likely to pick up to between 4% and 5% in the near term and to remain well above the 2% target over the next year or so, reflecting in part the recent increase in VAT. The near-term profile is markedly higher than in November, largely reflecting further rises in commodity and import prices since then. Further ahead, inflation is likely to fall back, as those effects diminish and downward pressure from spare capacity persists. But both the timing and extent of that decline in inflation are uncertain.

It is interesting to look back at the Inflation Reports of a year ago and two years ago to see what was being forecast then and to compare them with what has actually happened. It’s not too difficult to explain why the forecasts have turned out to be wrong. Hindsight is a wonderful thing. Unfortunately, foresight is less wonderful.

Questions

  1. Examine the forecasts for UK inflation and GDP for 2010 made in the February 2009 and February 2010 Bank of England Inflation Reports. How accurate were they?
  2. Explain the difference between the forecasts and the outturn.
  3. Why is it particularly difficult to forecast inflation and GDP growth at the present time for two years hence?
  4. What are the advantages of the Bank of England using a forward-looking rule as opposed to basing interest rate decisions solely on current circumstances?
  5. Explain whether or not it is desirable for interest rates to be adjusted in response to external shocks, such as commodity price increases?
  6. What do you understand by the term ‘core’ inflation? Is this the same thing as demand-pull inflation?
  7. How is the Bank of England’s policy on interest rates likely to affect expectations? What expectations are particularly important here?
  8. Explain whether or not it is desirable for interest rates to be adjusted in response to external shocks, such as commodity price increases?
