Optimal R&D intensity to maximize
output?
From an extended Cobb-Douglas
production function, the optimal R&D/GDP
ratio depends on
Purchase
price of R&D
R&D elasticity of output
Risk-free interest rate
Rate of R&D depreciation
Actual R&D to GDP ratio:
Wide variation in levels across countries,
even in EU
Variation in growth rates across countries,
even in EU
No clear sign of convergence, even in EU
??? Common target of 3% ???
Zooming in on the
country differences
in R&D/GDP
Variation in R&D elasticity of output
The sectoral dimension:
high-tech sectors (ICT..)with higher returns (higher opportunity,
measurement issues)

spending and Productivity Growth (US=1)

Linking R&D intensity and
Productivity Growth
Divergence bt countries in productivity growth
can be related to
Higher
R&D intensity in most sectors
Larger weight of R&D intensive sectors
Better growth performance in R&D sectors
Country divergence in R&D/innovation output
Beyond R&D: Innovation: Creation and diffusion
(European Innovation Scoreboard Indicators)
1. Human resources
S&E graduates, Population with tertiary education, Participation in life-long
learning, Employment in medium-high and high-tech manufacturing,
Employment in high-tech services )
2. Knowledge creation
Public R&D expenditures (GERD - BERD) (% of GDP) BERD) (% of GDP
(by source of funding), EPO&USPTO high-tech patent applications;
EPO&USPTO patent applications
3. Transmission and application of knowledge
SMEs innovating in-house, SMEs involved in innovation co-operation,
Innovation expenditures
4. Innovation finance, output and markets
Share of high-tech venture capital investment, Share of early stage venture
capital in GDP, SMEs sales of 'new to market' products, SMEs sales of
'new to the firm but not new to the market' products, Internet
access/use, ICT expenditures, share of manufacturing value-added in
high-tech sectors, volatility-rates of SMEs, TBP, High tech importsexports
Differences in Country Dispersion
between R&D and Innovation
Country heterogeneity in growth:
catching up?
The policy perspective:
How to improve innovative capacity?
creation and diffusion
Beyond stimulating R&D investments
Improving Technology Transfer/Diffusion ( Eg ISL
mechanisms, absorptive capacity of users, investment in
complementary assets)
Networking Among Actors on a Global Scale:
research, firms, finance, policy makers,…
Framework conditions, especially
clear
IPR regimes and standards;
flexibility in product markets (easy of entry), labour markets
(labour mobility),venture capital markets
This requires a Systemic Policy Approach
To feed systemic policy approach:
A call on theory, data, econometrics:
The right variables at the right level?
What are the driving forces for innovative capacity? Do we
have data on this
Esp diffusion capacity variables
Which country ideosyncracies matter to explain differences in
Levels of driving forces
Effects of driving forces
Sectoral composition
Time dimension (eg initial levels, catching up
Firm composition
Institutional setting…
Policy environment
Systems approach: interactions
