The document discusses how growth policy should be tailored based on a country's level of development. It provides examples showing that policies like competition, education, labor market flexibility, and finance are more growth-enhancing for countries closer to the technological frontier, while policies like primary education are more important for countries farther below the frontier. The document also emphasizes the importance of proper governance of growth policies and industrial policy targeted at competitive sectors.
2. EU versus US
1970’s: EU average annual growth
rate of per capita GDP: 3.5% versus
1.5% in US
1995-2006: EU per capita GDP was
growing at less than 2% versus 3% in
US
3. Latin America versus Asia
Average growth rate over 1960-200
period in Brazil lies between 2.5% and
3%...versus 7% in Singapore and
Taiwan, 6.5% in South Korea, 6% in
Hong Kong, 5% in Thailand.
4. Main debates
Does policy matter for growth as
long as countries have good
institutions?
Washington consensus: does one
size fit all: stabilize, liberalize,
privatize?
Should we preclude any form of
industrial policy?
Role and size of the state?
5. Growth diagnostics?
How can one binding constraints on
growth?
Using prices (Hausmann-Rodrik-
Velasco)?
Alternative approach?
7. Schumpeterian Paradigm
Innovation is driven by entrepreneurial
investments (R&D…) which are
themselves motivated by the prospect
of monopoly rents
8. Schumpeterian Paradigm
Frontier innovation and imitation
requires different sets of policies and
institutions
10. 1st idea: Appropriate growth
policies
During the post-war period, growth in
European countries was driven by
imitation
Over time, and particularly with
globalization, innovation has become
the driving force of growth
Innovation requires flexibility and
turnover, and different policies and
institutions
11. Example 1: Competition &
Growth
Competition/entry is more growth-
enhancing for countries or sectors that
are closer to technological frontier
Competition/entry is more growth
enhancing in countries or states with
less regulated labor markets
12.
13. 1991 Liberalization in India
Trade liberalization
– Large-scale abandonment of extensive system of quantitative
restrictions in the form of import licensing
– Average percentage point reduction 51% during 1990-7,
maximum of 270%, 97% of products affected
Foreign Investment and Technology Agreements
– Opening up of industries for automatic approval of foreign
technology agreements and investment of up to 51% equity
– Foreign Investment Promotion Board (up to 100% equity)
Industrial Delicensing
– Large-scale removal of industrial licensing, retained in a few
sectors (eg Motor Cars and Leather)

16. Discussion with Dany Rodrik
Is external competition enough to stimulate
growth in countries like India or South Africa?
Is there opposition between competition policy
and industrial policy?
17. Example 2: Education
Graduate education is more growth-
enhancing closer to technological
frontier
Undergraduate +primary/secondary
education is more growth enhancing
farther below technological frontier
Question: governance of education?
18.
19. Example 3: Labor market
flexibility
Labor market flexibility is more growth
enhancing the closer a country is to the
technological frontier
Question: how to make labor market flexibility
efficient and socially acceptable?

31. Example 2: Industrial Policy
Over time, and particularly since the 1980s,
economists have come to dislike sectoral
(“industrial”) policy on two grounds:
(i) it focuses on big incumbents (‘national
champions);
(ii) governments are not great in ‘picking
winners’.
Current dominant view is that sectoral policy
should be avoided especially when it
undermines competition
32. Industrial Policy (2)
Several reasons for a rethink
New post-crisis realism: laissez-faire complacency by
several governments has led to inefficient growth of
non-tradable sectors at the expense of tradables
Climate change: path dependence in the direction of
innovation leads firms that have innovated dirty in the
past will keep on innovating dirty in the future, hence
role for government to redirect technical change
China: a big deployer of sectoral aid, whose success
induces other countries to try and emulate its
economic policies
33. Industrial Policy (3)
The question is not so much whether or not
we should forbid or preclude industrial policy,
but rather how industrial policy should be
designed and governed.
Some new ideas
Selection of sectors: skill-biased (Nunn-Trefler
(2010)); competitive sectors (this paper);
Governance: do not focus aid on one firm in a
sector, minimize concentration of aid (this paper).

34. Industrial Policy (4)

Du, Ann Harrison, and Patrick Legros
Panel data of Chinese firms, 1988-2007
Industrial firms from NBS: annual survey of all
firms with more than 5 million RMB sales
Regress TFP on:
Subsidies received by firm as a share of sales
COMP=1 - LERNER INDEX
Sector-level controls, firm and time fixed effects
35. Industrial Policy (5)
Findings are that:
The higher competition, the more positive (or
less negative) the effect of subsidies on average
TFP
The overall effect of subsidies on TFP is positive
if competition is sufficiently high and/or subsidies
are not too concentrated among firms in the
sector
36. Innovation in Products
Here, we use the new product ratio as the dependent variable. New product
ratio is defined as the share of output value generated by new products to
the total output value.

38. Two Contrasted Views of How to
Conduct Macrooeconomic Policy
Keynesian view (non-discriminatory
increase in public spending)
Conservative view (tax and spending
cuts)
39. A Third Way
There is a third way between
keynesian and conservative
approaches
namely, countercyclical fiscal and
monetary policy to partly circumvent
credit market imperfections and
thereby help firms maintain their
growth-enhancing investments over
the cycle.
40. Fiscal Policy Over the Cycle
17 OECD countries, 45 manufacturing
industries
Period 1980-2005
Finding: Countercyclical fiscal
policy enhances growth more in
sectors that are more dependent on
external finance or in sectors with
lower asset tangibility
43. From fiscal to monetary policy
More countercyclical monetary policy,
i.e with lower short-run real interest
rates in recessions and higher rates in
booms...
....is more growth-enhancing in more
credit constrained or more liquidity-
constrained sectors
44. Conclusion 1: Summary
Policy matters
Not just institutions!
Growth policy must be “appropriate”
Interact policy with technological
development or with institutional variables
Governance matters
Governance of education
Governance of industrial policy
45. Conclusion 2: Growth diagnostics
Do not use prices to identify binding
constraints on growth
Problem with Mincerian measure of
human capital
Problem of using interest rates to
assess credit constraints
46. Conclusion 3: Make growth
sustainable!
Correct for excessive inequality which
is detrimental to growth:
• It encourages capture and undermines
competition and trust
• The top end stops contributing to public
good provision
Environment:
• State intervention to foster green
innovation and production
47. Developing countries: learning
from China
Fast convergence in per capita GDP and in
TFP
Huge surplus of foreign reserves (from 20
billion in 1992 to 2.5 trillion today)
Key was reallocation of activity from SOEs to
(credit-constrained) new TVEs and private
enterprises (Song-Storesletten-Zilibotti; Hsieh-
Klenow)
Role of education and infrastructure in
reallocation process?
48. Developed countries: learn from
Scandinavia and Germany?
Monti triangle: budget balance, growth and
inclusiveness
Targeted growth-enhancing investments and
countercyclical macroeconomic policy
Social dialogue (high unionization rates)
favoring external and internal labor market
flexibility
Fiscal systems to help reconcile budget balance
with growth investments and also help achieve
inclusive growth
