Standard of Living and Macroeconomics Indicators
1. Introduction: What Are Living Standards?
Living standards refer to the overall well-being of individuals in an economy. Economists often use Gross Domestic Product (GDP) growth as an indicator of living standards, but is GDP enough to measure well-being?
This chapter explores how GDP growth affects material and non-material standard of living (SOL), its shortcomings, and the other indicators needed to assess living standards more accurately.
2. How GDP Growth Explains Standard of Living (SOL)
GDP measures the total value of goods and services produced in an economy. When GDP grows, the economy is producing more, which can lead to higher incomes, more jobs, and better access to goods and services.
2.1 Material Standard of Living (SOL)
The material standard of living refers to the physical and tangible aspects of a person's quality of life. Essentially, these things can be directly measured and quantified, usually in terms of monetary value. This includes the income earned, the purchasing power of that income, and the quantity and quality of goods and services available.
Income and Purchasing Power of That Income
Income is one of the most common indicators of material standard of living. It refers to how much money a person or a household earns in a given period. This could be from employment wages, self-employment profits, or income from investments. Generally, higher income signifies a higher material standard of living, enabling individuals to acquire more goods and services that enhance their quality of life.
Example: In Singapore, for instance, the median monthly household income from work per household member rose from SGD 2,925 in 2019 to SGD 3,000 in 2020, representing a modest improvement in the material standard of living.
However, it's not just about how much income a person earns, but what that income can buy - the purchasing power. Consider this example:
John earns $2000 a month in Country A, while Mary earns $3000 in Country B. Initially, it seems like Mary has a higher standard of living. However, if the cost of goods in Country B is three times that in Country A, then despite earning more, Mary might have a lower material standard of living.
Quantity of Goods & Services Available
Income and purchasing power provides the means to acquire goods and services, but their true value comes to light only when considering the availability of these goods and services. Indeed, the quantity of available goods and services is a significant determinant of the material standard of living.
In a robust economy, a vast range of goods and services are available to consumers, allowing them to fulfil their diverse needs and wants. The more goods and services a market offers, the higher the potential standard of living, as it provides consumers with more choices and opportunities to enhance their lifestyles.
For instance, the availability of various food products, consumer electronics, transport services, entertainment options, and so on are key contributors to a better standard of living. Likewise, the availability of essential services such as healthcare and education also defines the material standard of living. It's worth noting that we're focusing purely on quantity, not quality, in this section.
To illustrate this, let's consider an example: In countries like the United States or Germany, the economies are diversified and highly developed, leading to a broad range of available goods and services. From numerous supermarket chains offering many food options to a well-established public transport system and an array of leisure and entertainment services, consumers have many choices. Consequently, these countries often rank high in terms of material standard of living.
2.2 Non-Material Standard of Living
While the material standard of living focuses on tangible aspects, the non-material standard delves into life's intangible and qualitative aspects. These aren't as easily measured as income or GDP, but they are vital in assessing the overall quality of life. These factors include working hours, access to quality healthcare and education, living conditions, and environmental pollution.
Working Hours
The average working hours can tell us a lot about a person's non-material standard of living. While longer working hours might translate into higher incomes, they could negatively impact other aspects of life, like leisure and family time, mental and physical health, and overall life satisfaction.
Example: In Japan, the phenomenon known as 'karoshi,' or death from overwork, highlights the negative implications of excessively long working hours on the non-material standard of living.
Access to Quality Healthcare and Education
Healthcare and education are two pivotal components of the non-material standard of living. Access to affordable, quality healthcare ensures that individuals receive medical attention.
Similarly, education plays a significant role in personal development and social mobility. A society with a high literacy rate and access to quality education often signals a high non-material standard of living.
Example: Scandinavian countries, known for their universal healthcare and high-quality education systems, provide an ideal example of how access to these services can uplift the non-material standard of living.
Living Conditions
Living conditions encapsulate a range of factors, such as housing quality, sanitation, and access to clean water. Inadequate living conditions can pose serious health risks and hinder social development, impacting the non-material standard of living.
Example: In some developing countries, poor sanitation and lack of clean water supply are pressing issues that lower the non-material standard of living.
Environmental Pollution
Environmental pollution affects the general population's health and quality of life. High levels of air, water, and soil pollution can lead to numerous health issues and diminish the enjoyment of natural resources, thereby reducing the non-material standard of living.
Example: In heavily industrialized cities like Beijing, smog and air pollution are persistent problems that significantly lower the quality of life.
Remember that while these factors help us understand and compare standards of living, they also have limitations. For example, averages and aggregates can hide disparities within a population, and some aspects are harder to measure than others. Therefore, it's important to consider a variety of indicators for a more holistic view. In the next sections, we'll delve deeper into these topics, providing further insights into living standards.
Real-World Example: Nordic Countries and Happiness
Despite moderate GDP growth, countries like Norway, Sweden, and Denmark consistently rank high in happiness indexes due to strong social safety nets, work-life balance, and low income inequality.
2. How GDP Growth Explains Standard of Living
2.1 How GDP Growth Explains Material SOL
Real GDP per capita is widely used to measure material well-being, as it reflects average income levels.
When an economy grows, people generally experience:
Higher wages and more job opportunities, leading to greater purchasing power.
Better access to goods and services, improving consumption patterns.
More government spending on infrastructure, healthcare, and education, enhancing overall welfare.
Real-World Example:
China’s rapid economic growth since the 1980s has lifted millions out of poverty. With rising incomes, people now have better access to housing, healthcare, and consumer goods.
2.2 How GDP Growth Explains Non-Material SOL
GDP growth allows governments to invest in public services, improving overall well-being.
Non-material SOL factors include:
Healthcare improvements, leading to longer life expectancy.
Higher education levels, improving skills and job prospects.
Better urban planning, creating cleaner and safer environments.
However, GDP does not account for happiness, income distribution, pollution, or work-life balance.
Real-World Example:
Nordic countries (Norway, Sweden, Denmark) have high SOL despite moderate GDP growth due to strong social safety nets and work-life balance policies.
3. Shortcomings of Using Real GDP to Measure SOL
3.1 GDP Does Not Reflect Income Distribution
Even if GDP grows, wealth may not be evenly distributed.
A high GDP does not mean everyone is well-off.
Real-World Example:
The U.S. has a high GDP, but the income gap between the rich and poor is growing, affecting overall SOL.
3.2 GDP Does Not Account for Environmental Costs
Economic growth can lead to pollution, climate change, and resource depletion, which reduce long-term well-being.
Real-World Example:
India’s industrialization has raised GDP, but cities like Delhi suffer from severe air pollution, lowering non-material SOL.
3.3 GDP Ignores Unpaid and Informal Work
Household work, caregiving, and informal jobs are not counted in GDP, even though they contribute to well-being.
Real-World Example:
Many people in developing countries work in the informal economy, but their contributions are not reflected in GDP statistics.
3.4 GDP Does Not Measure Work-Life Balance and Mental Well-Being
Some countries with high GDP have long working hours and high stress levels, which negatively affect well-being.
Real-World Example:
Japan’s culture of overwork has resulted in mental health issues, despite strong GDP growth.
4. Additional Indicators for Measuring Standard of Living
4.1 Indicators to Compare SOL Over Time
These indicators show whether living standards in a country have improved or worsened over time.
4.1.1 Human Development Index (HDI)
Measures income (GNI per capita), education (years of schooling), and life expectancy.
Provides a broader measure of SOL.
Limitation:
Does not capture income inequality or environmental quality.
Real-World Example:
Norway ranks highest on HDI due to its strong economy, excellent healthcare, and education systems.
4.1.2 Genuine Progress Indicator (GPI)
Adjusts GDP by including income distribution, environmental damage, and unpaid labor.
Limitation:
Difficult to measure across different countries.
Real-World Example:
The U.S. state of Maryland uses GPI to track economic progress beyond GDP.
4.1.3 Green GDP
Adjusts GDP by subtracting the costs of environmental damage.
Limitation:
Hard to assign monetary value to environmental losses.
Real-World Example:
China has experimented with Green GDP, but challenges in implementation remain.
5. Indicators to Compare SOL Across Countries
These indicators help compare living standards between nations.
5.1 GDP Per Capita (PPP - Purchasing Power Parity)
Adjusts for differences in cost of living between countries.
Limitation:
Does not measure income distribution, happiness, or social well-being.
Real-World Example:
Switzerland has a high GDP per capita, but other indicators provide a clearer picture of SOL.
5.2 World Happiness Index
Measures well-being based on social support, freedom, and life expectancy.
Limitation:
Subjective and may differ across cultures.
Real-World Example:
Finland ranks as the happiest country, despite not having the highest GDP per capita.
5.3 Gini Coefficient (Income Inequality Measure)
Measures income distribution, where 0 = perfect equality and 1 = extreme inequality.
Limitation:
Does not measure overall economic prosperity.
Real-World Example:
South Africa has a high Gini coefficient, reflecting extreme wealth inequality.
5. Conclusion
While GDP growth is an important measure of material standard of living, it does not fully capture income inequality, environmental damage, unpaid work, or work-life balance. Alternative indicators like HDI, GPI, Happiness Index, and Green GDP provide a more holistic understanding of living standards.
For students aiming to master macroeconomics, understanding these concepts is essential for A Level Economics tuition and real-world applications.
