Econ growth definition
increase in real value of the goods and services produced by an economy over time. Governments aim to achieve sustained, sustainable, and inclusive economic growth to better the SOL around the world
what is needed for sustained econ growth + definitions
actual growth: increase in national output produced in an economy over a given period of time (measured by percentage annual increase in real GDP)
potential growth: long run expansion of a country’s productive potential. It reflects the increase in the capacity of the economy to produce
AD change lead to actual growth explanation + graph
Rise in AD due to C, I, G or X-M
This will create shortage in goods and services and stimulate firms to increase the production of output via adopting more FOP. This leads to a rightward shift of AD curve from AD1 to AD2. This triggers the multiplier process creating many rounds of increase in induced consumption as one persons spending is another person income and income generates more spending. The multiplier process ends when the initial autonomous increase in AD is fully withdrawn in the form of savings, taxes and import expenditure where sum of injections = sum of withdrawals.
graph 1
AS change lead to actual growth explanation + graph
A fall in COP encourages firms to expand output at every price level. This is represented by a downward shift of the AS curve from AS1 to AS2 where RNY increases from Y1 to Y2.
graph 2
Actual growth explanation using PPC graph
Movement of a point outwards from within the PPC to closer on the PPC curve
graph 3
Potential growth explanation using AD/AS curve + PPC
PPC: Outward shift of the PPC curve as the maximum amount of consumer and capital goods that the economy can produce at full employment increases

Sustained growth explanation using AD/AS + graph
(just read)
For there to be sustained economic growth, actual growth must be accompanied by potential growth. Without an expansion of AS and potential output, rises in actual output will end once all spare capacity has been used up. Once full employment of labour and resources is reached at Yf1, any further increases in AD from AD1 to AD2 will only increase prices from P1 to P2. Actual output remains fixed at Yf1.
graph 6
Inclusive economic growth definition + explanation (just read for explanation)
rate of growth that is sustained over a period of time, is broad based across economic sectors and creates productive employment opportunities for the majority of the country’s population
When an economy achieves sustained economic growth in both its AD and productive capacity, the economy can potentially experience inclusive growth. Any autonomous increase in AD will lead to the multiplier effect. As one persons spending is another persons income, many sectors in the economy can experience a rise in induced demand and spending. This creates productive employment opportunities in these broad range of sectors across the economy, lifting income for many.
However, to ensure that the growth is inclusive, the economy must also take income distribution into consideration and ensure that any growth does not lead to worsening income and wealth inequality. As an economy grows and develops, because the fruits of growth may not be equitably distributed. Gini coefficient would rise and the government plays a crucial role in driving inclusive and equitable growth.
Sustainable growth definition + explanation (just read for explanation)
rate of growth that can be maintained without creating other significant economic problems such as depleted resources and environmental problems particularly for future generations. It also implies a positive and stable rate of growth over an extended period of time.
When an economy achieves sustained economic growth via continued growth in both AD and productive capacity, the economy can potentially experience sustainable growth as the govt and private sectors are more able and willing to spend on sustainable practices with increased tax revenue and income. (eg. public spending and private investments in renewable energy and clean transport infrastructure can directly reduce greenhouse gas emissions and pollution. This also reduces reliance on finite fossil fuels ensuring future generations have access to essential resources and REDUCES THE LONG TERM ENVIRONMENTAL IMPACT ON AN ECONOMY and prevents the productive capacity from declining rapidly over the long run)
Benefits of econ growth (4)
- Higher mSOL
- assuming population size remains unchanged, people will have higher purchasing power to due rise in real GDP per capita
- since more final goods and services are produced due to rise in RNY and made available for consumption to the average individual, mSOL improves
- actual growth also stimulates investments and potential growth
- as RNY increases, savings will increase as higher income induces higher savings
- will lead to an increase in supply of loanable funds in the credit market
- this will cause interest rates and cost of borrowing to fall and more investment projects will be undertaken leading to more actual growth
- stable growth also leads to increased business confidence and provide greater incentive for firms to invest
- higher capital expenditure allows the economy to expand its productive capacity and potential growth results
- sustained growth is achieved and there will be a continuous rise in RNY leading to higher mSOL - Higher nmSOL
- with higher income, people can afford better quality healthcare allowing for an increase in life expectancy and fall in infant mortality rate
- people are more able to take more time off for education, reflection and self fulfilment
- as the society gets richer, it will have a higher capacity to care for the environment and the less fortunate - Decrease in demand deficient/cyclical unemployment
- economic growth helps to create jobs as more goods and services are being demanded and produced, leading to higher induced demand for labour - Higher capacity for redistributing income and helping the poor
- rapidly growing economy can afford to be more generous to the disadvantaged
- rise in income leads to more tax revenue, enabling the government to spend more on transfer payments and subsidies to alleviate poverty and ensure social mobility
- lead to more inclusive growth
Cons of econ growth + graph (3)
- Overheating of economy and demand pull inflation
- result in tradeoffs with other macro goals such as stable and low inflation
- rapid increases in AD and actual growth can overheat the economy
- overheating occurs when AD rises excessively as the economy approaches full employment where resources are increasingly scarce, causing inflationary pressures in the economy
- a very large increase in eqm real output from Y0 to Y1 will be experienced as AD rises from AD0 to AD1 along the keynesian range of the AS curve due to the vast availability of untapped resources in the economy
- However, if AS remains constant with no increase in productive capacity, resources will become increasingly scarce. Further rises in AD from AD1 to AD2 then AD3 along the intermediate to AD4 on the classical range would lead to smaller and smaller extents of increases in real output over time.
- If AD goes on to rise beyond AD3 to AD4, real output cannot rise further to grow in a sustained manner as productive capacity is constrained at Yf with full employment of resources
- graph 7
- when AD rises rapidly while AD and productive capacity remains constant, the excess demand for goods must be met with the over employment of resources (eg. work extra shifts) which is hard to sustain as overemployment of resources cannot be supported indefinitely and will only lead to increases in GPL but not RNY and lead to demand pull inflation
- inflation can then hurt export competitiveness and cause uncertainty for investors and in turn, export revenue and investment will fall - Unequal and inequitable distribution of income
- propagates inequality
- real beneficiaries of growth tend to be the skilled and minority rich who already have the savings that enable new wealth accumulation and material gains from their financial investments
- this group will see a disproportionally bigger rise in their rental incomes and wealth when the economy grows
- inclusive growth is not achieved and reduces social cohesion
- can have adverse impact on nmSOL such as health, education and job security leading to alienation
- excessive wealth and income inequality gives rise to unequal access to opportunities and lead to reduced social mobility - Negative externalities and environmental costs
- encourage the creation of artificial needs and wants where consumers are induced to buy things that they have no intrinsic need for
- the greater the rate of growth and consumption, the greater the use of raw materials, leading to higher costs on the environment
- eg. large scale burning of fossil fuels is increasing the CO2 content in the atmosphere, creating harmful greenhouse effects, land clearing leads to haze, rising sea levels
- generates negative externalities on third parties, lowering their nmSOL
- lead to decrease in AS in the long run and hence unsustainable rate of future economic growth
what is desirable growth
healthy economic growth rate is neither too fast to create high inflation nor too slow to create recession
it should be sustained, sustainable and inclusive in nature
stable annual growth rate of around 2-3% for an advanced economy is ideal
what is undesirable growth
undesirable rate of economic growth involves declining or negative growth
declining growth: real GDP increasing but at a slower rate
negative growth: fall in real GDP which can arise due to a fall in autonomous AD or fall in AS
Causes of weak/negative economic growth (undesirable)
AD factors
AD factors:
- fall in AD will result in surpluses in goods and services which will lead to an increase in inventories in warehouses and firms will respond by reducing the production in the next time period, leading to a fall in RNY
- triggers the reverse multiplier process which will lead to a MTP fall in RNY due to many rounds of fall in induced consumption as a fall in spending by one person will lead to a loss in income for another person and less income leads to less spending.
- can be domestic (CIG) /international (X-M) factors
Causes of weak/negative economic growth (undesirable)
AS factors (5)
- Lack of fixed capital investment
- Private sector firms spend on new capital formation such as building new factor plants or buying new machinery, increasing I
- to keep increasing RNY at a satisfactory rate, economies must also spend on replacing its worn out and obsolete capital with the most up to date and technologically advanced equipment
- hence, the productive capacity and AD grows (QQT)
- when more capital stocks are made available for each worker, capital deepening, which is the increase in capital to labour ratio, is achieved
- productivity of labour would increase, leading to lower unit costs of labour and higher productive capacity to achieve economic growth
- hence lack of fixed capital investment will limit both actual and potential growth leading to weak or sluggish growth
- for capital stock to expand, a high savings rate in the country is needed to provide cheap and readily available funds for borrowing, especially when there is a lack of foreign investment
- however, savings rate is low in many developing countries (eg. high rates of poverty, high level of social security benefits that has reduced the need to rely on savings for rainy days), making it difficult to generate enough savings to provide funds to finance I projects - Lack of/fall in quantity or quality of natural resources
- increase in QQ (eg. discovery of new mineral deposits) will increase productive capacity and shift AS curve right
- destruction and depletion of non renewable resources and degradation of natural environment can threaten potential economic growth
- natural disasters like wildfires and human disasters like wars can destroy large areas of land
- unsustainable growth strategies can also lead to fall in QQ of natural resources reducing AS over time - Lack of investment in human capital
- workers are effective inputs if they are well educated, trained, healthy and motivated
- quality of labour can be improved through education and training
- as output per worker increases with labour productivity, the nations productive capacity will rise, pushing AS curve rightwards leading to potential growth
- assuming constant wages, the rise in productivity lowers COP leading to rise in AS and shifts downwards, leading to actual growth - Lack of tech advancement
- invention and innovation results in developments of new products and more efficient production of existing ones, leading to economic growth
- this can open new I opportunities as development in one industry can spread to related industries and set off a chain reaction
- average COP would fall as output per input increases with innovation hence both AS and AD will increase
- countries will little investment in tech will see slow growth with the use of archaic production methods and equipment
- rate of tech progress depends on success of scientists and innovators so there is great uncertainty with high costs and hence usually need institutional support (eg. govt subs) for research - Structural rigidities
- refers to a lasting feature in an economy caused by a set of institutions which prevents a market from operating freely
- eg. European countries have laws restricting businesses ability to lay off workers (contracts of indeterminate) which create job security but also labour market rigidity as firms find it hard to control costs especially during recessions making them more prone to closure
- eg. strong trade union results in high degree of coordination of wage bargaining processes and minimum wage setting hence firms face high labour costs and severance payouts making it hard and costly to hire and fire
- eg. Greece has strong barriers to entry involving excessive regulations that deter foreign investment
- many countries undergo structural reforms but this can lead to the vulnerable having to cope with the cost of adjustments
consequences of weak/negative economic growth (5)
- Higher unemployment
- rise in cyclical unemployment will occur when an economy is facing negative growth/recession
- technical recession: fall in real GDP for 2 consecutive quarters
- firms will hire fewer FOPS to produce reduced level of output
- unemployment will lead to forgone output, strain on govt budget (lower tax revenue, higher payouts), social issues, hysteresis - Lower SOL and savings
- assuming no change in population, during a recession, there is a fall in RNY which shows a fall in purchasing power of an average individual
- households earn and consume less when they are not working and hence the lower ability to consumer goods and services causes mSOL to deteriorate
- lower tax revenue to to lower income taxes, corporate income taxes and consumption taxes means less funds are available for govt spending on social services which lowers nmSOL
- no excess income to save and might even need to draw past savings to ride through economic hardship, which affects future SOL - Slower long term economic growth rates due to pessimistic outlook
- workers fear further loss of jobs/loss of income
- consumer confidence declines and consumers tend to save/cut down on expenditure
- also leads to a fall in investor confidence and firms expect lower profitability on their future sales and cut back on risky investments so I falls
- fall in C and I lead to further fall in AD resulting in deepening of the recession
- lower rate of I and capital production will slow econ growth - Lower inflation rate
- if a country is suffering from overheating and high inflation, a slower growth rate may slow donw the rate of price increases - Influences on BOP position
- with recession, fall in RNY reduces purchasing power
- consumers hence consume FEWER NORMAL GOODS and services, including imports
- net exports increase and improves trade balance in the current account
- but a recession may worsen investment sentiments and cause foreign investors to withdraw their investment funding and relocate businesses from the country and result in a net outflow of capital funds, thus worsening the capital and financial account fo the BOP
- net impact depends on relative sizes of impact on BOT and kfa
Causes of unsustainable economic growth + a bit on consequences
- weak environmental protection laws and lower environmental protection standards to drive rapid growth and compete for FDI
- subsidies that encourage excessive use of fertilisers and pesticides which pollute and destroy the environment or encourage overharvesting of already depleted fish stocks - rapid urbanisation and industrialisation
- deforestation, resources depletion and unsustainability
- global biodiversity continues to decline due to habitat loss
- land degradation and desertification worsens due to deforestation and poor agricultural practices
- increased fossil fuel consumption for industrialisation and growth means increasingly polluted air and water
- cost of health damage caused by air pollution amounts to $8.1 trillion a year about 6.1% of global GDP
- poor, elderly, and young children from poor families are the most affected
- uncontrolled growth of motor vehicles, reliance on more polluting fuels for power generation and specialisation in more polluting industries also play a part in hindering sustainable growth
summary of consequences
- resource depletion
- climate change
- loss of biodiversity
- health issues
- global inequality
Consideration of sustainable growth (just read)
concerns have led countries to consider sustainable development and growth as their policy goal which involves a commitment to less wastefulness, greater conservation and socially responsible ways to allocate natural resources
2021 Glasgow COP26 meeting had more than 40 countries agree to gradually phase out the use of coal and many also vowed to end deforestation while pledging $19 billion in financing which will go to developing countries to restore damaged land, tackle wildfires and support indigenous communities
SG green plan 2030 –> by 2030, at least 20% of schools will be carbon neutral and over 50% increase in nature park land with cycling paths tripling in length and rail network expanded
causes and consequences of non inclusive economic growth + SG examples
Causes:
- economic restructuring from low value added, labour intensive production to high value added capital intensive production would bring about economic growth
- benefits capital owners at the expense of low skilled workers, widening the income gap and worsening inclusivity
- globalisation can boost export oriented industries while hurting industries that produce goods substitutable by imports, generating greater income disparity
- insufficient effort by govt to redistribute income and wealth
- try to be eco friendly and shut factories but never help the employees find new jobs
Consequences:
- high income and wealth inequality
- low income and social mobility
- lack of social cohesion due to inadequate growth opportunities for all
Singapore examples
- SG faces challenges in narrowing its income gap due to globalisation, increased competition and lack of relevant skills of low skilled workers
- productivity gains also declined to due higher reliance on foreign labour inputs
- Sg govt believes that productivity driven growth is the means to deliver inclusive economic growth and has put in place policies to help increase the productivity of workers (eg. measures to alleviate the economic burden on the lower income groups and facilitate social mobility via tax rebates and increased subsidies on healthcare and education)
Definition of unemployment
Situation where people who are available for work and are actively seek work cannot find jobs
Full employment:
situation where all FOPS are fully and efficiently utilised (production lies on the PPC curve)
Types of unemployment (just list)
- Demand deficient/cyclical
- Structural
- Frictional
Demand deficient/cyclical unemployment
Unemployment caused by a fall in AD (associated with recessions where national income falls for at least 2 consecutive quarters or undergoes a steep slowdown in growth)
- lack of demand for labour derived from lack of demand of goods and services in the economy
- due to fall in AD from AD1 to AD2, it leads to a contraction of output across many industries and a lower level of national output at Y2 is produced instead of Y1
- firms will hire fewer FOPs including labour to cut costs and maintain profits (labour shedding/down sizing)
- more workers are laid off creating spare capacity and higher unemployment
Structural unemployment (4)
Unemployment due to a mismatch of skills between the unemployed and the skilled needed by producers seeking labour
usually long term and chronic and may exist even when the economy is not in recession and may be due to
- Changes in pattern of demand
- change in tastes and preferences or invention of new and better substitutes
- production gradually decreases in the affected industry (making it a sunset industry)
- unemployed workers struggle to relocate to a new industry where very different skills are needed
- eg. closure of mines in US, UK and China leaving miners struggling to find work due to boom in natural gas as alternative source of electricity - Foreign competition
- globalisation allows developing countries (eg. China/India) to provide cheap labour due to large population size (eg. clothing manufacturing)
- attracted many companies from developed countries to relocate their manufacturing facilities to these developing nations and workers then become unemployed - Changes in tech and occupational immobility
- with advancement in tech, workers must upgrade their skills to complement the methods of production and be productive but this is difficult and takes time
- new tech can also substantially increase productivity allowing companies to reduce their labour demand without affecting overall output
- though job vacancies may exists, firms will only offer jobs to workers with the relevant skills
- many jobs are left vacant due to occupational immobility which is the lack of ability/willingness of people to take up new jobs as they dont have the right skills (eg. unwillingness to receive training/ineffectiveness of training due to steep learning curves) - Geographic immobility
- lack of ability/willingness of people to relocate within a country to find jobs
- eg. decline in South Wales coal mining industry led to high unemployment in Welsh valleys but the miners didnt want to relocate to other regions in England with coal mining activities
- could be due to changes in cost of living/financial costs associated with moving or because of family and social ties
Frictional unemployment
unemployment of workers when they take time to search for jobs and remain jobless in the meantime
- due to IMPERFECT INFORMATION of existing market conditions
- workers are ignorant of all available job opportunities and the work they entail while firms do not know what labour is available for them to choose from hence time is needed to find the right job match
- occurs for new entrants to the labour force and for people transitioning between jobs
- inevitable and always exists
- usually not severe and lasts only a short duration
- can be improved using different platforms (eg. LinkedIn)
