THE CIRCULAR FLOW OF ECONOMIC ACTIVITY
Basic Economic Activities • Production • The use of economic resources in the creation of goods and services for the satisfaction of human wants.
• Consumption • The u 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.
Two Economic Units • Household • The basic consuming unit. • Firm • The basic producing unit.
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.

Implications of the Circular Flow of Economic Activity 1. The goods, resources, and money payments will flow as long as households continue to consume, and as long as firms continue to produce. 2. 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.
Inflows and Outflows • Outflows Withdrawals (factors that decrease the level of economic activity) • Savings • Taxes • Imports
• Inflows Injections (factors that increase the level of economic activity) • Investment • Government Spending • Exports

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.
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.
