Company

26. Root of Macroeconomics #1
 Microeconomics examines the behavior of
individual decision-making units—business
firms and households.
 Macroeconomics deals with the economy
as a whole; it examines the behavior of
economic aggregates such as aggregate
income, consumption, investment, and the
overall level of prices.
 Aggregate behavior refers to the behavior of all
households and firms together.

Macroeconomists often reflect on the
microeconomic principles underlying
macroeconomic analysis, or the
microeconomic foundations of
macroeconomics.
28

29. Root of Macroeconomics #3
Classical economists applied
microeconomic models, or “market
clearing” models, to economy-wide
problems.
However, simple classical models failed
to explain the prolonged existence of high
unemployment during the Great
Depression. This provided the impetus
for the development of macroeconomics.

41

42. Components of Macroeconomics #4
 Households and the government purchase
goods and services (demand) from firms in the
goods-and services market, and firms supply
to the goods and services market.
 In the labor market, firms and government
purchase (demand) labor from households
(supply).

The total supply of labor in the economy depends on
the sum of decisions made by households.
42

43. Components of Macroeconomics #5
In the money market—sometimes called
the financial market—households
purchase stocks and bonds from firms.

Households supply funds to this market in the

 Firms, government, and the rest of the world
also engage in borrowing and lending,
coordinated by financial institutions.
