Business Dynamism, Job
Reallocation Rates and the UK
Productivity Puzzle
(1998-2018)
Neha Prashar and Mark Hart
2. Main Research Objective
• Analyse how the business stock in the private
sector in the UK has changed over 1998-2018 and
the relationship to recent productivity stagnation
(the productivity puzzle)
• Davis et al (2008) noted that higher turbulence and
reallocation of jobs in the economy is productivity
enhancing and leads to better living standards.
• Particular focus on job creation and destruction
pre-recession (1998-2008) and post-recession
(2009-2018)
3. Data and Methodology
• Data used is the ‘Business Structure Database’
(BSD) complied by the ONS sourced mainly from
HMRC.
• Job Creation = Total employment change due to
new firms entering the market or firms expanding
• Job Destruction = Total employment change due
to firms exiting the market or firms contracting
• Job Reallocation Rate = Job Creation + Job
Destruction
• Net Employment = Job Creation – Job Destruction

• The highest level of
business dynamism is in
the hotel and restaurant
service industry, which is
to be expected as many
of these jobs may be
part-time, zero-hour
contract or seasonal
type employment.
• There is a very sharp
drop in job reallocation
rates in the financial
sector, where rates fell
by 11.3 percentage
points post-recession
and manufacturing
sector which saw a 5.8
drop in percentage
points.
• Overall, business
dynamism across all
sectors dropped post-
recession.

• Firms with a single
employee experience
a higher level of job
turbulence when
compared with larger
firms.
• There was a slight
decline post-recession
in entry and exit rates
across all of the
different sized firms
but trends remained
the same.
• Firms with 5 to 9
employees and 10 to
24 employees saw the
least change post-
recession – a drop of
around 2 percentage
points in job
reallocation rates.
8. Conclusion
• Post-recession saw a decline in JR rates in the UK. They have not yet
returned to pre-recession levels and this is holds true at varying levels
when looking at different regions, sectors and size.
• This goes hand-in-hand with the slowdown in productivity. Less
dynamism means less productivity-enhancing turbulence in the job
market.
• Businesses are hiring and firing all the time but it is the ‘normality’ of the
scale of those actions which often goes unreported – in both good times
and bad.
• Grasping the level of job churn in underlying base assumptions on the
future performance of the UK economy is fundamental for policy
makers, especially with the recent political climate.
