What Kind of Supply-Side Policy
for the UK?
What Implications for Scotland?
Nicholas Crafts
Competitive Advantage
• Translate as ‘competitiveness’ in the sense of
‘the degree to which a country can produce
the goods and services which meet the test
of international markets, while
simultaneously maintaining and expanding
the incomes of its people over the long term’
• So focus is on productivity performance
The Five Drivers
The previous government identified the
following as the key to productivity
performance:
Investment
Skills
Innovation
Enterprise
Competition
Still a useful starting point
What is Conducive to Strong
Productivity Performance?
• Strong investment and innovation based on
expected profitability
• Diffusion of new (especially imported)
technology based on good incentive structures
• Strong competition in product markets
• Success stories: pharma (HK, R & D); ICT
diffusion (relatively favourable regulation);
financial services (agglomeration benefits)
Endogenous Growth:
Key Policy Areas
• Public capital
• Innovation
• Regulation
• Competition/Openness
• Taxation
• NB: links to 5 drivers
Policy Implications (1)
• Should intervene to address ‘market failures’,
e.g. where social returns exceed private returns
• May be able to raise growth rate.. a bit
• Much better to incentivize innovation than
physical investment
• UK investment subsidies were a very expensive
failure – high deadweight loss
Policy Implications (2)
• Policy could work through raising expected
returns or making managers try harder
• ‘Productive’ government expenditures
can raise the growth rate; ‘distortionary’
taxes do the opposite
• Need to decide balance between
competition policy and industrial policy
Competition and Productivity
Growth
• Absence of competition allows managers to be
sleepy if ineffective shareholders
• Competition is strongly positive for productivity
outcomes in UK firms without dominant
shareholder (Nickell et al., 1997)
• Competition promotes better management
practices (Bloom and van Reenen, 2007)
• Strengthening competition addressed Britain’s
1970s’ productivity problem quite effectively
(Crafts, 2012)
Creative Destruction
• Central to technological change and long-run
economic growth
• Exit/entry of plants accounted for about ½ of
TFP growth in UK manufacturing between 1980
and 1993 (Disney et al., 2003)
• As with freer trade, economic benefits but lost
votes
• Commitment technology to prevent
intervention may be desirable
Government Failure
• Politics of improving supply-side policies
often unattractive; improving productivity
typically means losers as well as winners (cf.
trade liberalization)
• Lessons of the 1960s and 1970s should not be
forgotten; HS2 and ‘save the high street’ belong
to those decades
• ‘Institutional architecture’ is key area for
reform (cf. LSE’s Infrastructure Commission)
Diffusion
• Matters more for productivity performance than
original invention and deserves more attention
from policymakers
• Vast majority of new technology in UK comes
from R & D in ROW (Eaton & Kortum, 1999)
• Information does matter but need also to think
about absorptive capacity, intangibles and
profitability of adoption

Wholesale and Retail Trade
• Would be considered irrelevant by traditional
industrial policy
• Does not do much R & D (0.5% of UK R & D)
but is the sector that contributed most to recent
UK labour-productivity growth
• Is a big user of new technology
• Has been adversely affected by planning
regulations; TFP in modern supermarkets
reduced by at least 20% (Cheshire et al., 2011)
Agglomeration Economies
• External economies of scale from
localisation and urbanisation economies
• Increase with city size (though not
without limit)
• Much bigger in services: financial
services = 0.25, manufacturing = 0.04
(Graham, 2007)
• Are not fully realised if transport
inadequate or city size restricted

Industrial Policy
• Can define as “public sector intervention aimed
at changing the distribution of resources across
economic sectors and activities” (Caves, 1987)
• Market-failure rationale might be provision of
public goods or addressing divergence between
social and private returns
• Proponents claim positive effects on rate of
economic growth
Types of Industrial Policy
• Horizontal policies target innovation, skills,
infrastructure etc. generally though their impact
is not necessarily sector-neutral
• Sector-specific policies are explicitly selective
and aim to increase the size of particular
industries
• Since the early 1980s the emphasis in UK has
been on horizontal policies including especially
strengthening competition in product markets

UK Success Stories
• Have been promoted by horizontal not selective
industrial policy
• Pharma: human capital, science base
• Financial Services: human capital, deregulation, planning reform, transport
• ICT Diffusion: human capital, industrial
relations reform, less obstructive regulation than
elsewhere in Europe
Horizontal Industrial Policies:
Could Do Better
• Infrastructure
• Education
• R&D
• Taxation
• Regulation
NB: effects on growth through the incentives to
invest, innovate and adopt new technologies
Infrastructure: Government Failure
• Pre-crisis investment in public capital shortfall:
1.3% GDP per year below growth-maximizing
amount (Crafts, 2009)
• E.g, lots of road projects with high BCR not done
• Eddington Report (2006) – big welfare gains and
tax revenues from efficient programme of road
building and road pricing – ignored
• Perhaps roads should be provided by a
regulated utility (Helm, 2012)
Education: Could Do Better
• ‘Cognitive skills’ strongly correlated with long-run
growth; 100 test-score points → 1.4 ppts per year
(Hanushek & Woossman, 2011)
• Institutional design matters a lot for educational
outcomes (principal-agent)
• International comparisons suggest UK could raise scores
considerably by greater private operation (and probably
by having higher-quality exams) (OECD, 2007)
• Key point: better incentive structures could improve
educational quality without spending more money

R & D: a Mixed Picture
• SME Innovation Support: has
incentivized innovation with high BCR
(Foreman Peck, 2013)
• R & D Tax Credit: also has high BCR but
design issues (Griffith et al., 2001; Bond & Guceri, 2012)
• Patent Box: badly targeted, revenue
reducing, benefits highly questionable
(Griffith et al., 2012)
Tax Doesn’t Have to be So Taxing
• Mirrlees Review (2011) presents powerful case
for reform
• For example, revenue-neutral extension of VAT
base to all consumption and reform of capital
taxation by exempting normal rate of return to
raise GDP by 1.4% and investment by 6.1%
• More generally, OECD research finds significant
increases to GDP from shifting taxes from
income to consumption and property (Arnold et
al., 2011)
Planning Rules Matter
• An important horizontal ‘industrial policy’
• Planning restrictions impose massive distortions
in land use – regulatory tax rate of around
300% makes office space in Manchester more
expensive than Manhattan (Cheshire & Hilber, 2008)
• Successful British cities are too small and
constraints on growth threaten to undermine
competitive advantage
• Spatial adjustment to globalization is inhibited
What is the Most Effective Role
for UK Government?
• Good horizontal industrial policies and strong
pro-competition stance; not back to the 1970s
• Address market failures and remember CBA
• Facilitate diffusion; don’t fixate on R & D
• Recognize that the globalized world of today has
implications for the design of industrial policy
Two Technological Revolutions
• Steam:
Transport costs fell
Industrialization & deindustrialization
Lancashire cotton
• ICT:
Communications costs fell
Vertically-disintegrated trade
Computers and robots
Smile-Curve Economics:
• Fabrication stages become commoditized
• Value shifts to pre- and post-fabrication services

Value Chains
• Now more complex and more globalized
• Big ‘manufacturers’, e.g., Rolls-Royce, make a
lot of their money from services
• Need much better metrics to understand how
these input-output connections
• ‘Rebalancing’ should not be conceptualized
simply in terms of ‘manufacturing’
Implications of VerticallySpecialized Trade
• Most value added not in making manufactures
• Need to think in terms of stages not sectors of
production; so horizontal industrial policies
matter more
• Successful rebalancing implies more jobs in
business services which is where ‘real
engineering’ will be found in future
Successful Cities
• Fundamental to competitive advantage (cf.
The Netherlands of 2040); attracting the right
people is key.
• Have hard-to-replicate agglomeration
advantages
• Underpinned by good horizontal policies,
notably, land-use planning and transport
• NB: Edinburgh (4th) and Glasgow (16th) in 2013
competitiveness index for British cities
Implications for Scotland
• An independent Scotland could make
horizontal industrial policies more
growth friendly
• If Ireland is a role model, it is only in the
Celtic Tiger period – not before or since
• As a small country, the optimal rate of
corporate profits tax would be lower
Absorptive Capacity
• Even more than for UK as a whole, diffusion is
key for Scotland so absorptive capacity of
business really matters
• Worrying diagnostic that relatively few Scottish
businesses are ‘innovation active’ (33%
compared with 60% in Ireland and Sweden)
• A high priority is to understand and address this
shortfall (Turnbull & Richmond, 2013)
Policymaking Architecture
• Need to do better than UK in mitigating
‘government failure’ especially given postrecession populism
• Serious independent evaluation and surveillance
of microeconomic policy
• Could consider an equivalent to OBR or NICE
(cf. the Australian Productivity Commission)
Varieties of Capitalism
• UK policy discussion has really been about
improving the functioning of a ‘liberal market
economy’ (Hall & Soskice, 2001)
• Perhaps Scotland would like to become a
‘coordinated market economy’?
• If so, comprehensive institutional reform
would be the focal point to move to an economy
with more patient capital, more training and
wage moderation
Conclusions
• Evidence-based supply-side reforms could
improve UK productivity performance
• The politics of improving productivity is
challenging
• An independent Scotland should consider
institutional as well as policy reforms
• A return to the 1970s is not a good idea
