About the Seminar

“Confused about the rate of inflation?  You have every right to be…”  was the title of an article by Andrew Sentance in the Times of 23rd January 2023, pointing out “no one is using or referring” to CPIH, the official measure of inflation provided by the Office for National Statistics (ONS).

Now, more than a year later, public awareness of CPIH remains at less than half that of the RPI, with claimed familiarity even lower. In addition, recent developments have again called into question the methods employed to calculate CPIH.   The lack of awareness of this measure is particularly unfortunate because almost every member of our adult population has some lived experience of the effects of inflation, it is therefore vital that the public should have confidence in how it is recorded.

Moreover, whatever the expert may say, the public is mainly inclined to consider that the change in purchasing power of money is relatively simple to track from one period to another, although it is widely appreciated that different people will have different experiences of inflation.  A fact that had led to the development of the Household Cost Indices (HCIs), as originally proposed by Jill Leyland and John Astin in 2015[1].  These are now produced by the ONS on a quarterly basis and the ONS also introduced a Household Cost Calculator in March 2023, for individuals to check the inflation rate of households similar to their own[2].

Although it may be simple to understand the principles underlying the calculation of the inflation rate, there are a wide range of uses and it is notable that the government uses different measures for different purposes, for example RPI has until recently formed the basis for calculating increases in rail fares whereas CPI is used for the old age pension.

This seminar is therefore expected to explore issues such as:

  • Has the decision to remove the status of a National Statistic from the RPI contributed to the increase in households unable to make ends meet?
  • If people change behaviour due to inflation should this change the index?
  • Is it better to have a readily understood index than a truly accurate one?
  • is it possible to have one index when there are many different purposes?
  • What next for the Household Cost Indices – should one of the HCI measures replace the RPI instead of CPIH as the replacement?

Additionally we will be exploring how the measurement of inflation is best governed; specifically are the two separate advisory committees ‘stakeholder’ and ‘technical’ the right way to serve the public good?  Don’t miss this event!
