Scarcity – basic condition which exists when
unlimited wants exceed limited productive
resources
Trade-offs – alternatives that must be given up
when one choice is made over another

Supply – schedule of quantities offered for
sale at all possible prices in the market
Law of Supply – rule stating that more will be
offered for sale at high prices than at lower
prices
Competition, price, and equilibrium



Price – monetary value of a product as
established by supply and demand
Competition – the struggle among sellers to
attract customers while lowering costs
Equilibrium price – price where quantity
supplied equals quantity demanded
Unit 3 – Business Organizations

Unit 4 – Macroeconomics –
Measurements of the economy
The means by which economic
activity is measured


Gross Domestic Product (GDP) – the dollar
value of all final goods, services, and
structures produced within a country’s national
borders during a one-year period
Consumer Price Index (CPI) – index used to
measure price changes of frequently used
consumer items
The means by which economic
activity is measured


Inflation – the rise in the general level of
prices over time
Unemployment rate – ratio of unemployed
individuals divided by the total number of
people in the civilian labor force, expressed as
a percentage
The means by which economic
activity is measured



Economic growth – a sustained period during
which a nation’s total output of goods and
services increases
Recession – a decline in the nation’s total
output of goods and services for two or more
quarters
Depression – a severe recession where the
economy experiences large numbers of
unemployed and general economic hardship
The means by which economic
activity is measured



Deficit spending – spending by the

(taxes) to influence the economy
When implementing fiscal policy through taxing
and spending decisions, the government
impacts the nation’s economy
International Trade


Absolute advantage – a country’s ability to
produce more of a given product than another
country
Comparative advantage – a country’s ability
to produce a given product relatively more
efficiently than another country; production at a
lower opportunity cost
International Trade


Both production and consumption increase
when individuals, businesses and governments
specialize in what they can produce at the
lowest opportunity cost and then trade
At different times nations advocate free trade
or erect trade barriers for different reasons
International Trade
Trade barriers:
 Tariff – a tax placed on an imported product
 Embargo – a prohibition on the export or
import of a product
