Chapter 6: Problem 26

Why might per capita GDP be only an imperfect measure of a country's standard of living?

Short Answer

Expert verified

Per capita GDP is an imperfect measure of a country's standard of living because it doesn't account for factors like income inequality, quality of public services, non-material aspects of well-being, environmental and social costs, and the informal economy. It is an average measure that may mask disparities in wealth distribution and does not reflect the quality of public services, happiness, social cohesion, safety, or negative externalities. A combination of indicators should be used to better assess the standard of living.

Step by step solution

Understanding Per Capita GDP

Per capita GDP (Gross Domestic Product) is the total economic output of a country divided by its population. It is a commonly used metric to estimate the average income and standard of living in a country.

Limitations of Per Capita GDP as an Indicator

There are several reasons why per capita GDP might not accurately capture the standard of living in a country. Factors such as income inequality, quality of public services, and non-material aspects of well-being should be considered.

Income Inequality

Per capita GDP is an average measure and doesn't account for the distribution of wealth within a country. A high per capita GDP might mask significant income inequality, meaning that a large proportion of the population has a lower standard of living than the average suggests.

Quality of Public Services

Per capita GDP does not reflect the quality of public services such as education, healthcare, and infrastructure. In countries with high GDP but low investment in public services, the standard of living might be lower than the per capita GDP suggests.

Non-material Aspects of Well-being

Per capita GDP does not account for non-material aspects of well-being, such as happiness, social cohesion, and safety. These factors can greatly influence the standard of living and may not be reflected in GDP measurements.

Environmental and Social Costs

GDP is a measure of total economic output, which means it does not consider the negative effects of economic activity, like pollution or social costs. A country with high per capita GDP might have a lower standard of living if negative externalities are significant.

Informal Economy

Per capita GDP only measures the formal economy and does not account for the informal economy. In some countries, the informal sector can contribute significantly to the overall well-being of a population. By not considering this, the per capita GDP may underestimate the standard of living. In conclusion, per capita GDP alone is an imperfect measure of a country's standard of living, as it doesn't account for factors like income inequality, quality of public services, non-material aspects of well-being, environmental and social costs, and the informal economy. To better assess the standard of living, a combination of indicators should be used.
