2. Basic Economic Activities
Production
• The use of economic resources in the creation of goods and
services for the satisfaction of human wants.
Consumption
• The using up of goods and services by consumer purchasing
or in the production of other goods.
Employment
• The use of economic resources in production; engagement
in activity
Income Generation
• The production of maximum amount an individual can spend
during a period without being any worse off.
3. Two Economic Units
Household
• The basic consuming unit.
Firm
• The basic producing unit.
4. Stock and Flow Variables
Flow
• A quantity measured over a particular period of time.
Stock
• A quantity measured as of a given point in time.
The concepts of stock and flow measurements
are essential in understanding the economic
variables of wealth and income.
Wealth
• Anything of valued owned. It is a stock since it is what is
owned at a particular time.
Income
• The rate at which we earn money. It is a flow since income
that is saved, increases the stock of wealth.

13. Implications of the
Circular Flow of Economic Activity
The goods, resources, and money payments
will flow as long as households continue to
consume, and as long as firms continue to
produce.
That since goods and resources flow in
exchange for payments, the rate of
payments flow will in the end be the same.
Money is the inducing factor, and the pillar of
the price system. Without it, there is no price
system.
14. Inflows and Outflows
Outflows (factors that decrease the
level of economic activity)
• Savings
• Taxes
• Imports
Inflows (factors that increase the level
of economic activity)
• Investment
• Government Spending
• Exports

16. Outflows are difficult to control because
they are dependent on income. When
income increases, we expect savings,
taxes, and imports to increase.
Inflows are easier to manipulate. The
proper use of policy enables the
government to encourage exports and
investments and to increase its
expenditures when it desires to expand
the flow of economic activity.
17. Three Sets of Policy
Monetary policy
• Affects the savings and investment.
Fiscal policy
• Controls taxes and government expenditures.
Trade policy
• Affects a country’s exports and imports.
