Chapter 23: Measuring a Nation's Income

Chapter 23 talked about GDP, or Gross Domestic Product; what it is, how it is measured, and what it reveals. GDP is defined as the market value of all the final goods and services produced within a country within a given period of time and is used to calculate the total expenditure and total income of a nation. The formula for GDP is the sum of a nation's consumption, investment, government purchases, and net exports. GDP can be measured as nominal GDP, which measures the production of goods and services at current services, and as real GDP which measures the production valued at constant prices according to a base year. Nations with a high GDP can afford better education and healthcare systems, while nations with low GDP often have lowered life expectancy, higher infant/maternal mortality, and less access to clean water.
