Real GDP growth compared to previous year (per cent), Source: IMF
• Economic growth is a
long-term expansion of
productive potential
• Short term growth is the
annual % change in real
national output
• Long term growth is
shown by an increase in
trend or potential GDP
and this is illustrated by
an outward shift of long
run aggregate supply

4. Short Run and Long Run Economic Growth
Short term economic growth
Cyclical changes in real GDP
Changes in AD (C+I+G+X-M)
Changes in short run AS
Short term external shocks to
both demand and supply
Short term policy changes e.g.
changes in interest rates
Long run economic growth
Potential output / trend growth
Productivity of labour & capital
Technological progress and
strength of enterprise
Changes in the labour force
Investment rates

5. Key Factors Affecting Short Run Economic Growth
Interest rates set by
the central bank
Fiscal policy -
government spending
and taxation
Commodity prices
such as oil, gas and
foodstuffs
Exchange rates Trading conditions in
other countries
Confidence of
businesses and
households

10. Some of the Key Drivers of Economic Growth
Economic
growth
Expanding the capital stock
Increasing the active
labour supply
Extracting and
selling natural
resources
Improving factor
productivity
Driving innovation and
enterprise
Economic growth is a
sustained rise in a country’s
productive potential and real
national output
The main drivers of long run
economic growth are higher
productivity and gains from
innovation and rising real
incomes for households

11. Linking Capital Investment to Economic Growth
Injection of demand for
capital goods industries
Bigger capital stock can lift
productivity / incomes
Economies of scale &
better competitiveness
Investment helps to sustain
export-led growth

12. What are the main Benefits of Economic Growth?
Higher living standards – i.e. Real GNI per capita –
helps to lift people out of extreme poverty and
improve development outcomes (e.g. rising HDI)
Employment effects – sustained growth stimulates
jobs and contributes to lower unemployment rates
which is turn helps to reduce inequality.
Fiscal dividend – higher economic growth will raise
tax revenues and reduce government spending on
unemployment-related welfare benefits
Accelerator effect - rising growth stimulates new
investment e.g. in low-carbon technologies. Better
growth may attract foreign direct investment projects

13. Is there a Virtuous Circle of Economic Growth?
Higher real
national output
(GDP)
Increased capital
spending
Increased output
per head
(productivity)
Increased wages /
real incomes for
people
Rising consumer
spending on
goods and
services

14. Benefits from Growth driven by Technological Change
A rise in
productivity
• Higher GDP per worker
• Lower unit costs
• Higher wages
• Higher profits
New
Goods
and
Services
• Lower real prices
• Consumer welfare
gains (lower prices)
• Improved living
standards
Improved
health
• Healthy life

growing countries both in recent years and in the forecast
• What factors have contributed to rapid economic growth?
Rapid Economic Growth in Africa

17. • What factors have contributed to rapid economic growth?
1. Improvement in the terms of trade – higher commodity prices have boosted
export revenues for many countries
2. Improved governance – wider spread of democratic governments allied to
improved institutions e.g. more countries are able to issue bonds
3. Strongly increasing foreign direct investment – especially in agriculture,
mining, oil and gas, infrastructure, hotels/restaurants
4. Increasing intra-regional trade including manufactured goods – emergence
of key African regional trade hubs bolstered by infrastructure spending
5. Improved macroeconomic management – lower inflation, more credible
central banks, improved fiscal balances
6. Rising per capita incomes – growth of consumer markets – poverty rates
continue to fall but social progress has been uneven
7. There is some evidence that a growing number of African countries are
becoming less dependent on primary commodities and building a more
diversified manufacturing / services base for their economy.

20. High rates of GDP growth can bring about undesirable economic
and social costs – much depends on the nature of growth
Risks of higher inflation and higher interest rates
• Fast-growing demand can lead to demand-pull and cost-push inflation –
this leads to a conflict between macro objectives
• The central bank may decide to raise interest rates to control inflation
Environmental effects
• More negative externalities such as pollution & waste
• Risk of unsustainable extraction of finite resources – i.e. fast growing
countries may cause a long-run depletion of natural resources
Inequalities of income and wealth
• Rapid increases in real national income can lead to a higher level of
inequality and social divisions
• Many of the gains from growth may go to only a few people

23. Main Sources of Economic Growth in China
China has experienced rapid growth over the last twenty years
helping to lift hundreds of millions of people out of deep poverty
• Real GDP growth in China has been over 9% per year since 1979
• 60-70% has come from increasing capital and labour inputs –
there has been a vast increase in capital investment spending
• 30-40% has come from rising factor productivity (i.e. increasing
efficiency in the allocation of labour & capital resources)
• Looking at increases in per capita output research finds that:
1. 11-14% from improving human capital (quality of labour)
2. 8-14% from improving allocative efficiency (e.g. moving from
state-owned businesses to private and from rural to urban)
3. 16-17% has come from the productivity-enhancing effects of
innovation – much of which has been the imitation of ideas

24. Growth Challenges for China in the Years Ahead
China is now in a period of transition away from the fast
export and investment-led growth of the last 20 years.
The service sector is likely to take a bigger share of GDP
in the years ahead. In 2014, it still accounted for less
than 50 per cent of Chinese national output.
Chinese Reform Challenges
1. More reliance on their
own domestic market
and less on exports
2. Raise consumption and
reduce inefficient
savings
3. Grow the private sector
and reduce distortions
from state-owned sector
4. Increase the pace of
innovation as imitation
limits are reached
5. Continue to integrate the
Chinese economy into
the global economic /
financial system. This
includes many more

Dependency
Macroeconomic
Instability
Endemic Conflict
and Corruption
Human Capital
Weaknesses

Private Savings
Natural Capital
being Depleted
Rising Income
Inequality
Although many developing countries have enjoyed rapid growth in
recent years, for others there are crucial growth constraints

26. Savings Gaps: Importance of Savings and Investment
Increase
national
savings
Increase in
net
investment
Larger
capital
stock
Rise in real
GDP / GNI
Increased
per capita
incomes
How a savings gap can limit
economic growth:
• In many smaller low-
income countries, high
levels of extreme
poverty make it almost
impossible to generate
sufficient savings to
provide the funds
needed to fund capital
investment projects.
• This increases reliance
on tied overseas aid
• Some countries borrow
heavily to fund capital
investment projects –
this can lead to a high
level of external debt

27. Deficiencies in Human Capital as Barrier to Growth
Human capital weakness
limits the positive impact of
capital investment
Investment increases the size of
the capital stock and helps to
achieve “capital deepening”
(more capital per worker) but
businesses need skills and
experience to make best use of
new technologies
In many countries there are acute
shortages of human capital
Some countries lose some of their
skilled workforce to other
countries through a brain drain
Investment in education and training to increase the quality of the
labour force and make people more flexible in the labour market
