1980s

Introduction• Wage inequality in the UK has risen since the 1980s
www.skope.ox.ac.uk
Introduction• Rising upper- and lower-tail inequality until mid 1990s• Small increases in upper-tail inequality since mid 1990s (except at very
top), coupled with falling inequality at bottom end

Workforce composition• Education and earnings are strongly correlated• Increasing the size of the more educated groups drives up inequality

Workforce composition• Other compositional changes also have inequality-increasing effects• This is true for past decade too

The wage structure• Overall effect on inequality depends on structure of wages associated with
these variables• For education:
– Increasing demand for skills widens earnings inequality between the more and less educated groups
– Increasing education attainment could reduce earnings inequalities as earnings benefits spread more widely

The wage structure• We do see inequality reducing changes in the wage structure...

Distribution of jobs• Seems to reflect ‘correction’ of compositional changes – not as many
people in high wage jobs as we’d predict

Conclusion• Policymakers tend to work with a ‘room at the top’ mindset focus on
supply of skills through increasing educational attainment• Higher wage jobs are more scarce that this suggests – limits the ability of
education to reduce labour market inequalities• The problem may be a different sort of ‘demand for skill’ problem to the
one the UK has often faced – not a market failure or a problem of short-termism.
• In the mean time, should leads to a great concern about intergenerational inequalities
