Economic Growth
Economic Growth
Indicators of economic growth include indicators of living standards, as well as the growth in real GDP and the growth in real GP per capita. Economic growth include actual growth, potential growth, sustained growth, sustainable growth and inclusive growth.
Measuring Economic Performance using GDP Per Capita Growth
To measure the performance of an economy, we often look at GDP per capita growth. GDP (Gross Domestic Product) is the total value of goods and services produced within a country. GDP per capita divides this value by the population, providing a measure of the average income of citizens.
Growth in GDP per capita usually indicates that a country is becoming wealthier, and living standards are improving. For example, when Singapore sees consistent growth in GDP per capita, its citizens experience higher income levels, improved infrastructure, and better quality of life.
However, GDP per capita is not a perfect indicator. It doesn’t capture issues like inequality or environmental sustainability. That’s why it’s important to use additional indicators to assess whether economic growth is truly good for everyone.
Real-World Example:
Singapore’s steady growth in GDP per capita has transformed it into a highly developed nation. The country’s focus on education, infrastructure, and healthcare has improved its citizens' standard of living.
Actual growth
This refers to the real economic growth experienced by a country over a specific period, typically measured by the annual percentage change in Real GDP. It reflects the actual expansion of the economy's productive capacity and the resulting increase in the production of goods and services.
Graphically, it is usually illustrated by an increase in AD, but can also be achieved via an increase in AS or both such that there is a rightward shift in the AD curve, AS curve or both.
Potential growth
This represents the economy’s maximum production in the long run. It refers to the increase in output brought about by an increase in the productive capacity (full employment output) of an economy. It considers factors like quantity and quality of available resources, technological advancements, and more.
Graphically, it is represented by a sustained outward shift in AS, such that there is a rightward shift in the LRAS curve.
Sustained Economic Growth
Combines the ongoing increase in actual GDP (year-on-year) with the gradual expansion of the economy's potential growth over time, which means adding up both actual growth and potential growth. This signifies a continuous improvement in the economy's ability to produce goods and services, leading to rising living standards and improved well-being for the population.
Graphically, it is represented by a sustained rightward shift in both AD and AS curves.
Sustainable growth
An actual increase in real national output of an economy that can be sustained without any significant trade-offs related to microeconomic or macroeconomic objectives, or negative consequences like depletion of resources and environmental degradation so future generations can continue to enjoy economic growth. These conditions need to be met for sustainable growth:
Potential Economic Growth: Actual economic growth is constrained by potential economic growth. A continuous increase in AD without accompanying rise in AS will likely cause high demand-pull inflation, which is undesirable and unsustainable.
Environmental Sustainability: Ensuring economic activities don't deplete natural resources or cause irreversible environmental damage and negative externalities which negatively impact the future economic growth
Resource Management: Utilising resources efficiently and promoting renewable energy sources.
Simultaneously, these issues should not manifest themselves in a significant manner when the economy grows:
Higher inflation (Measured by changes in CPI and increase in GPL): Increases in AD where the economy is already operating at full employment level are not matched by an accompanied increase in AS
Higher Income Inequality (Measured by GINI coefficient): Wages increase more rapidly for higher income groups but stagnant or slow for lower income groups.
Increased Environmental Degradation (Measured by various environmental indicators such as the Pollutants Standards Index): A rapid increase in economic activity may result in more pollution due to an increase in energy use, waste generation and emissions.
Significant Increase in Public Debt: Growth financed by fiscal spending may lead to future generations having to pay higher taxes or higher interest payments which occupies a portion of the government budget which is an opportunity cost for future generations.
Inclusive growth
This refers to economic growth that is distributed fairly across society and creates equitable opportunities for all. It focuses on productive employment rather than direct income redistribution as a means of increasing the incomes of relatively poor and excluded groups and raising their living standards.
In Singapore, the focus is on including low-skilled workers in the pursuit of economic growth through education and training to:
Reduce Income Inequality: Narrowing the gap between the rich and the poor through policies that promote equal access to education, healthcare, and economic opportunities.
Empowerment and Participation: Ensuring all segments of society have the chance to contribute to and benefit from economic growth.
Indicators that measure inclusive growth include:
GINI Coefficient (After government taxes and transfer payments): To inspect if redistributive programmes have had an impact on levels of income inequality
Growth in Median Wages: Whether an average worker has seen an increase in wages by the same extent as those in different income brackets.
Benefits of Economic Growth
1. Increased Living Standards
Economic growth leads to higher real GDP per capita, signifying greater production of goods and services per person. This translates to higher incomes, improved access to goods and services, and a better overall quality of life.
2. Employment and Reduced Poverty
As economies grow, more jobs are created, leading to lower unemployment rates and reduced poverty. This fosters greater social stability and well-being.
3. Fiscal Dividend
Higher economic activity generates increased tax revenue for the government. This allows for increased spending on public services like education, healthcare, and infrastructure, further improving living standards.
4. Investment and Innovation
Economic growth creates an environment conducive to investment in physical and human capital, as well as technological advancements. This fuels further growth and expands the economy's productive capacity.
5. Increased Consumer Demand
As incomes rise, consumer demand strengthens, stimulating production and economic activity through the multiplier effect.
Costs of Economic Growth
1. Environmental Degradation
Increased economic activity often leads to higher resource consumption, pollution, and environmental damage. This can have long-term consequences for sustainability and human well-being.
2. Worsen Income Inequality
Economic growth may not be equally distributed to all segments of society. Unequal access to opportunities and resources can lead to widening income gaps and social unrest.
3. Resource Depletion
Unsustainable economic practices can lead to the depletion of finite natural resources, hindering future growth and posing long-term challenges.
4. Inflationary Pressures
Rapid economic growth can sometimes lead to excess aggregate demand, putting pressure on prices and causing inflation. This can erode purchasing power and create economic instability.
5. Social and Cultural Disruption
Rapid economic change can disrupt traditional social structures and cultural values, potentially leading to social unrest and a decline in social cohesion.
2. Problems with Negative Economic Growth (Recession)
2.1 What Is a Recession?
A recession is when the economy experiences negative growth for two consecutive quarters. This means that the total value of goods and services produced is declining. A recession can lead to widespread problems, such as rising unemployment, lower income levels, and reduced consumer spending.
When a country enters a recession, businesses tend to cut back on production and hiring, leading to even less demand. This creates a vicious cycle of economic contraction.
Real-World Example:
The 2008 global financial crisis triggered a recession in many countries. The U.S. economy, for instance, saw massive job losses and a sharp decline in consumer spending. The effects were felt worldwide, with high unemployment and slow recovery in several nations.
2.2 Policies to Resolve Recession
To overcome a recession, governments can use monetary and fiscal policies:
Monetary policies: Central banks can lower interest rates, making it cheaper for businesses and individuals to borrow and spend. This stimulates demand.
Fiscal policies: Governments can increase public spending or offer tax cuts to boost demand and create jobs.
Quantitative easing: This is when central banks buy financial assets to increase the money supply and encourage lending and investment.
Real-World Example:
During the 2008 recession, the U.S. Federal Reserve implemented low interest rates and quantitative easing to revive the economy. In the UK, the government increased spending to reduce unemployment and stimulate growth.
3. Achieving Inclusive Growth
3.1 What Is Inclusive Growth?
Inclusive growth is about ensuring that the benefits of economic growth are shared by all segments of society, especially lower-income and marginalized groups. Inclusive growth aims to reduce income inequality, improve access to education, healthcare, and social services, and create opportunities for everyone.
However, achieving inclusive growth is not easy. It requires addressing issues such as income inequality, lack of access to services, and discrimination.
Real-World Example:
In India, economic growth has lifted millions of people out of poverty, but income inequality remains a significant issue. There is a stark contrast between the wealth of urban areas and the poverty in rural regions.
3.2 Policies to Achieve Inclusive Growth
Governments can implement policies to promote inclusive growth by:
Progressive taxation: Tax systems that tax the rich more heavily can help redistribute wealth to support the less fortunate.
Investing in education and healthcare: Ensuring all citizens have access to quality education and healthcare is key to promoting economic opportunity.
Job creation: Governments can invest in rural areas and create job opportunities for underrepresented groups, such as women and minorities.
Real-World Example:
South Korea’s investment in education and healthcare in the 1960s and 1970s helped build a more equitable society, supporting rapid growth and poverty reduction.
4. Achieving Sustainable Growth
4.1 What Is Sustainable Growth?
Sustainable growth refers to an economic expansion that meets the needs of the present without harming future generations’ ability to meet their own needs. However, achieving sustainable growth can be difficult due to:
Environmental degradation: Economic activities such as industrialization can harm the environment, contributing to pollution and climate change.
Overuse of resources: Excessive extraction of natural resources can lead to depletion.
Social inequality: Growth that benefits only a few can limit the long-term stability of an economy.
Real-World Example:
Brazil’s rapid industrialization during the 20th century led to deforestation in the Amazon, raising concerns about the sustainability of its growth.
4.2 Policies to Achieve Sustainable Growth
To achieve sustainable growth, governments can:
Invest in renewable energy and green technologies to reduce environmental impact.
Implement strict environmental regulations to limit pollution and encourage sustainable practices in industries.
Promote sustainable agriculture and manage resources in a way that does not deplete them for future generations.
Real-World Example:
Germany’s investment in renewable energy and eco-friendly policies has led to sustainable growth. The country has become a global leader in renewable energy while reducing its carbon emissions.
5. Conclusion
Economic performance is typically measured by GDP per capita growth, but it’s important to distinguish between actual growth and potential growth. While negative growth (recession) can cause widespread economic challenges, governments have tools at their disposal to stimulate recovery. Achieving inclusive and sustainable growth requires careful policymaking to ensure that everyone benefits from growth and that the environment is preserved.
For students pursuing A Level Economics tuition or online economics tuition, it’s essential to understand these macroeconomic concepts and the role they play in real-world economic management.
