  • The exchange rate:
    • Price at which different currencies are traded.
  • To make comparisons of GDP across countries we must take the following steps:
    • GDP must be expressed in a common currency by first adjusting it by the exchange rate.
    • This value of nominal GDP must be multiplied by the ratio of prices in the countries.

Example: China and United States

  • First, use the exchange rate to turn Chinese yuan into U.S. dollars.
  • Adjust for relative price level of goods.
  • Price level ratio is about (1/0.3), so the real GDP of China is $11.7 trillion.
  • Comparison of countries:
    • In general, rich countries tend to have higher price levels than poor countries.
    • This is mainly because poor countries have lower wages.
