3. Blue Book 2023
@ONSfocus
Revisions are a natural part of our compilation of GDP – timeliness vs accuracy
• The UK is a large and complex economy, so it takes time to be able to bring together all the
information we need to produce a full picture of the economy (e.g. 2-3 years)
• We need to revise our estimates as new information becomes available – for example,
how much output was produced by each industry or what inputs were used in production
• Our annual Supply-and-Use Tables approach allows us confront detailed data at a granular
product and industry level, giving us more accurate estimates of the economy
The Coronavirus (COVID-19) pandemic made this process even more challenging
The next quarterly GDP estimates, to be published on Friday 29 September, will include our
recently announced annual revisions for first time

14. Conclusions
• Inflation persistence remains a focus for policymakers
• There are some signs that the labour market is cooling,
yet wage inflation still remains high
• Consumers are reporting an improvement in personal finances

17. What is inflation persistence?
We describe inflation persistence as the underlying
trend inflation rate in the economy – common across all
the goods and services making up the CPI.
We published an article on 21 August 2023:
Persistence in consumer prices inflation, UK: 2002 to 2023
@ONSfocus #ONSEconForum slido #26920

18. Inflation persistence and core inflation
“The name of the game then was distinguishing the signal from
the noise, which was often difficult. The key question on my mind
was typically what part of each monthly observation on inflation
is durable and what part is fleeting?”
(Alan Blinder,1997)
Last October we published this article:
New estimates of core inflation, UK: 2022
@ONSfocus #ONSEconForum slido #26920

19. Methodology
For each of the 85 goods and services (i = 1, 2, …, 85) in
the CPI we use filtering techniques to split the inflation
rate into a common (St) trend rate and a specific individual
component(ϵi,t):
CPI1,t = St + ϵ1,t
⋮ ⋮
CPI85,t = St + ϵ85,t

@ONSfocus #ONSEconForum slido #26920

21. Top 10 most persistent inflation items
Those goods and services with a strong correlation to the
common trend rate (high signal-to-noise)
* Why are personal/housing
services good indicators of the
underlying trend inflation rate in the
UK economy?
Research from the FRB NY finds
that services inflation tends to be a
more important driver of core
inflation than goods inflation
because it more closely follows
longer-term inflation expectations
and conditions in the labour market.

23. Top 10 least persistent inflation items
Those goods and services with a poor correlation to the
common trend rate (low signal-to-noise)
* Energy-related items, inflation
rates are volatile relative to the
common underlying trend rate of
inflation.
* Technology-related items,
hedonic price adjustments give
these items different trend
inflation rates to the common
underlying trend.

26. Summary
• The persistent part of CPI inflation has been slower to reach a
turning point and the fall has been less than for the headline
all-items rate
• Inflation persistence measures consistent with other estimates
of UK core inflation

27. Changes in labour costs
and prices
Christina Palmou
Office for National Statistics
@ONSfocus #ONSEconForum slido #26920

28. How do firms pass-through input costs?
Businesses have many ways to react to higher prices of inputs:
• Reducing profit margins to cover higher costs
• Passing on costs to consumers with higher prices
• Reducing purchases of inputs and reducing output
• Substituting away from more expensive types of inputs
• Increasing productivity

35. Is there a wage price spiral?
@ONSfocus #ONSEconForum slido #26920

36. Wage and price increases in the BICS
• Businesses that reported wage increases in the previous month were
59% more likely to report price increases, controlling for other price
pressures
• Business that reported increases in the cost of their inputs were 73%
more likely to report price increases
• Finally, businesses are more likely to increase prices if they are
facing difficulties filling in vacancies or demand increases
@ONSfocus #ONSEconForum slido #26920

37. How have firms reacted to wage increases?
• In several service industries, labour costs are important so wage rises
could explain most price growth since 2019
• In manufacturing even after large wage increases, industry output price
growth is driven mainly by other factors
• Overall, there is no clear evidence that there has been a change in the
correlation between wage increases and output price increases
• In a whole economy BICS sample, businesses reporting an increase in
wages were 59% more likely to report an increase in output prices, more
so if they are facing increases in demand or tight labour markets.

On 29 June 2023, we launched a public consultation on our proposals for a transformed
population and migration statistics system. These statistics cover a wide range of areas,
including household characteristics, employment, health, religion and international migration.
We welcome contributions from all users. This includes those who are experienced users of
ONS’s statistics, through to those who are looking to use ONS population and migration data
for the first time. We value everyone’s feedback.
More information on the consultation can be found at consultations.ons.gov.uk/ or you can
