Lecture Notes: Real GDP Per Capita as a Measure of Standard of Living

Introduction

• Real GDP per capita is often criticized for being too materialistic.
• It's not a perfect measure but is often considered the best single measure of a country’s average standard of living.

Correlation with Other Indicators

• Life Expectancy
  • Positive correlation between real GDP per capita and life expectancy.
  • Higher GDP per capita often means higher life expectancy.
• Happiness
  • Positive correlation also observed between GDP per capita and happiness.
  • Higher GDP per capita tends to correlate with higher happiness levels.
• Human Development Index (HDI)
  • Combines life expectancy, education, and standard of living.
  • General trend: as GDP per capita increases, HDI also rises.

Limitations of GDP Per Capita

• Income Distribution
  • Does not account for income distribution within a country.
  • Example: Nigeria, Pakistan, and Honduras have similar GDP per capita but different poverty levels due to income inequality.
• Poverty Levels
  • Income inequality leads to higher poverty rates despite similar GDP per capita.

Growth in GDP and Income

• Over time, growth in GDP per capita often indicates growth in incomes across all income levels, including the poorest.
• Positive correlation between growth in average income and income growth among the poorest 20%.

Conclusion

• Real GDP and GDP per capita are useful measures for comparing living standards across countries or over time.
• The big question remains: how to increase the standard of living and grow real GDP per capita?
