GDP, living standards and national wellbeing

Limitations of GDP for comparing living standards

• Distribution: an average says nothing about inequality; most of the gain may go to a few.
• Hidden economy: untaxed and unrecorded activity is missed, and its size differs between countries.
• Non-market output: unpaid work such as caring and housework is left out.
• Quality of life: leisure time, working hours, pollution, health and education are not directly captured.
• Composition: spending on defence or cleaning up after a disaster counts the same as spending on consumer goods.
• Measurement: data quality varies, and exchange rates distort comparisons unless PPPs are used.

Happiness and wellbeing

Some governments and statistics agencies collect subjective wellbeing data by asking people questions such as how satisfied they are with their lives or how happy they felt yesterday, on a scale of 0 to 10. Wider indicators include health, education, environment, relationships, security and governance.

Real income and happiness

Higher real incomes raise wellbeing most strongly when incomes are low, because they pay for food, housing, health care and security. Many studies find that once basic needs are met, extra income adds less to reported happiness, and people compare their income with others, so if everyone gets richer relative position may not change. Other factors such as health, employment, relationships and trust matter a lot. So growth in real GDP is linked to happiness, but the link weakens as countries get richer.

Worked example

Country A has higher real GDP per capita at PPP than Country B. Give two reasons why living standards in A might still be lower.

1. Income in A may be much less equally distributed, so the typical household is poorer.
2. People in A may work much longer hours or suffer worse pollution, which GDP does not record.

Answer: Inequality and quality-of-life factors (hours, pollution, health) are not shown by GDP per capita.

Check yourself

1. Why does a large hidden economy make GDP a poor measure of living standards?
   • It raises the price level
   • It is counted twice in GDP
   • Output that is not recorded is left out of GDP
   • It increases imports
   Show answer

   Output that is not recorded is left out of GDP. Unrecorded, untaxed activity is missing from official GDP, so output and incomes are understated.

2. Real GDP per capita rises by 3%, but the income of the poorest 50% falls. This shows that GDP per capita
   • does not show how income is distributed
   • is measured in nominal terms
   • ignores population growth
   • includes transfer payments
   Show answer

   does not show how income is distributed. An average can rise while many people become worse off.

3. Which activity is NOT included in GDP?
   • A nursery worker caring for children for a wage
   • A government paying a teacher
   • A parent caring for their own child at home
   • A firm building a new factory
   Show answer

   A parent caring for their own child at home. Unpaid work has no market transaction, so it is not counted.

4. What does research on happiness generally suggest about real income?
   • Happiness rises in proportion to real income at all levels
   • Extra income adds less to reported happiness once basic needs are met
   • Real income has no link with happiness
   • Happiness falls as real income rises
   Show answer

   Extra income adds less to reported happiness once basic needs are met. The link is strongest at low incomes and weakens at higher incomes.

5. After a flood, spending on repairs raises GDP. Why might this overstate living standards?
   • Repairs are not counted in GDP
   • It reduces imports
   • It lowers the price level
   • The spending replaces what was lost rather than adding to wellbeing
   Show answer

   The spending replaces what was lost rather than adding to wellbeing. GDP counts the repair spending, but people are not better off than before the flood.

6. Explain one reason why a fall in real incomes might reduce subjective happiness.
   Show answer

   Lower real incomes mean households can afford fewer goods and services, which may cause financial stress and worry about meeting basic needs, so life satisfaction falls.. A two-stage chain: lower real income, less purchasing power, more stress or unmet needs, lower life satisfaction.

7. Workers in Country X work 20% more hours than in Country Y for the same GDP per capita. Which is the best conclusion?
   • Living standards must be equal
   • X has higher living standards because it works harder
   • GDP per capita must be wrong
   • Living standards may be higher in Y because people there have more leisure
   Show answer

   Living standards may be higher in Y because people there have more leisure. Leisure has value but is not counted in GDP.
