Document Summary
Microeconomics - the study of how individual households and firms make decisions and how they interact with one another in markets. Macroeconomics - study of the economy as a whole. Gdp measures the total income of everyone in the economy, and the total expenditure on the economy"s output of goods and services (these two are the same!) For an economy as a whole, income must equal expenditure. An economy"s income is the same as its expenditure because every dollar spent by a buyer is a dollar of income for some seller. Gdp equals the total amount spent by households in the market for goods and services and it also equals the wages, rent, and profit paid by firms in the markets for the factors of production. Economy is more complicated than that because households do not spend all of their income and do not buy all the goods and services in the market, some are bought by the government.
