Introduction
Economic growth rates are commonly used as a measure of a country’s economic performance, reflecting changes in real Gross Domestic Product (GDP) over time. A higher economic growth rate generally indicates increased national output, higher income levels, and improved employment opportunities. However, while economic growth can contribute to an improved standard of living (SOL), it is not necessarily an appropriate measure for comparing living standards between two different economies, especially between developed and emerging economies. Differences in economic structure, absolute income levels, currency valuations, data accuracy, quality of life, and externalities can all limit the usefulness of economic growth rates as a direct measure of living standards.
Limitations of using economic growth rates in comparing SOL of 1 country with that of another
Differences Between Developed and Emerging Economies
Economic growth rates tend to be higher in emerging economies than in developed economies due to differences in their stages of development. Emerging economies can achieve rapid growth by adopting and importing existing technologies from developed economies, increasing productive capacity without requiring innovation.
In contrast, developed economies have already implemented many of these productivity-enhancing technologies and must rely on new innovations to drive further growth, leading to slower but more stable economic expansion. As a result, a higher economic growth rate in an emerging country does not necessarily imply a higher standard of living compared to a developed nation with a lower growth rate.
For example, an emerging economy with a 7% growth rate may still have a lower overall standard of living than a developed country with a 2% growth rate, as the developed country may already have higher incomes, better healthcare, and superior infrastructure.
Differences in Absolute Purchasing Power
Economic growth rates indicate the rate of change in economic activity, but they do not reflect the absolute level of wealth or purchasing power in a country. A country with a high GDP growth rate but a low GDP per capita may still have a lower standard of living compared to a country with a low growth rate but a high GDP per capita.
For example, consider Country A (an emerging economy) with a GDP growth rate of 15% but a GDP per capita of USD 10,000, compared to Country B (a developed economy) with a GDP growth rate of 1% but a GDP per capita of USD 60,000.
Despite the higher growth rate, Country B likely has a much higher standard of living due to its higher absolute income levels, better public infrastructure, and access to quality healthcare and education. This highlights how growth rates alone do not provide a complete picture of standard of living, as they fail to account for existing levels of wealth and development.
Impact of Currency Valuations on GDP Comparisons
When comparing standard of living across countries, GDP figures are often converted into a common currency, typically the US dollar (USD). However, fluctuations in exchange rates can distort these comparisons. A country’s GDP per capita in USD terms may decline if its domestic currency depreciates, even if its real standard of living remains unchanged.
For example, after Brexit, the British pound depreciated significantly against the USD, causing the UK’s GDP per capita (in USD) to fall sharply. However, this did not necessarily indicate a corresponding decline in the UK’s standard of living, as domestic purchasing power remained relatively stable.
Similarly, if an emerging economy’s currency appreciates, its GDP per capita in USD terms may rise, even if its real living standards have not improved substantially. This suggests that economic growth rates, especially when measured in foreign currency terms, may not accurately reflect real improvements in standard of living.
Accuracy of Data Collection in Different Economies
The reliability of economic growth rates depends on the accuracy of data collection, which can vary significantly between countries.
In large, developing economies, particularly those with significant rural populations, economic activity may not be fully recorded, leading to inaccurate GDP estimates.
Many emerging economies also have sizeable informal sectors, including illicit transactions, tax evasion, and informal employment, which are not captured in official GDP statistics.
This means that official GDP growth rates may either overstate or understate actual economic activity, making them unreliable for comparing standard of living across economies.
Developed economies typically have more accurate and transparent data collection methods, reducing the likelihood of measurement errors. However, this discrepancy makes it difficult to compare economic growth rates between developed and emerging nations with equal reliability.
How economic growth rates may not be useful in comparing certain aspects of standard of living with another country
Differences in Quality of Life
While economic growth rates reflect changes in GDP, they do not account for differences in quality of life between countries. Healthcare standards, such as life expectancy, infant mortality rates, and access to medical care, are not captured in GDP growth rates. Education quality and literacy rates, which significantly influence long-term well-being, are also not reflected in economic growth statistics. For example, a country with rapid GDP growth but poor healthcare and education infrastructure may have a lower overall quality of life compared to a slower-growing, high-income nation with excellent public services. Thus, while economic growth contributes to improving material well-being, it is not a sufficient indicator of overall living standards.
The Presence of Negative Externalities
High economic growth rates do not necessarily translate into higher well-being if growth is accompanied by negative externalities such as environmental degradation and pollution. Rapid industrialisation in emerging economies often leads to high carbon emissions, deforestation, and pollution, which can harm public health and reduce quality of life. In contrast, developed economies with slower growth rates may prioritise environmental sustainability and cleaner energy policies, resulting in better air quality and healthier living conditions. For example, China’s high economic growth rate has come at the cost of severe air pollution in cities like Beijing and Shanghai, leading to health problems and lower life expectancy for residents. Economic growth rates, therefore, do not reflect the environmental and social trade-offs associated with economic expansion, making them an incomplete measure of living standards.
Conclusion
While economic growth rates are useful indicators of how quickly an economy is expanding, they are not always appropriate for comparing standard of living between different economies. Factors such as absolute income levels, exchange rate fluctuations, data accuracy, quality of life, and negative externalities all influence how economic growth translates into real well-being for citizens. Developed economies may have lower growth rates but higher living standards, while emerging economies may experience high growth but still struggle with poverty, income inequality, and poor public services. As such, economic growth should be considered alongside other indicators, such as GDP per capita, income distribution, healthcare and education quality, and environmental sustainability, to obtain a more comprehensive and accurate comparison of standard of living between countries.
