Chapter 3
Economics: the social science that studies the choices people and
governments make when dividing up their scarce resources.
It is important to understand:
o How the activities of one industry affect the activities of other
industries.
o How these activities fit into the overall picture of the country.
Microeconomics: the study of small economic units (i.e. individual
consumers, families, businesses etc.)
Macroeconomics: the study of a nation’s overall economic issues, such as
how an economy maintains and divides up resources and how government
policies affect its citizens’ standard of living, and also the effect on the overall
world economy with these policies.
The choices about where to spend money also help to set the prices of goods
and amounts sold.
Demand: the willingness and ability of buyers to purchase goods and
services.
Supply: the willingness and ability of sellers to provide goods and services.
Demand is affected by:
o Customer preferences and incomes.
o Prices of substitute and complementary items.
o Number of buyers in the market.
o Strength of the buyers’ outlook for the future.
Demand Curve: a graph of the amount of a product that buyers will purchase
at different prices.
Demand curve can shift (keeps the same shape):
o Right: increase in demand at all prices.
o Left: decrease in demand at all prices.
Supply Curve: a graph that shows the relationship between different prices
and the amount of goods that sellers will offer for sale, regardless of demand.
Supply curve can shift (keeps the same shape):
o Right: increase in products to buy at lower prices.
o Left: decrease in products to buy at lower prices.
Law of supply/demand states that prices are set by the intersection of the
supply/demand curves.
Equilibrium Price: the current market price for an item.
Economic systems can be divided into three categories:
o Private enterprise systems.
o Planned economies
o Mixed economies.
There are four market structures in the private enterprise system:
o Pure Competition (i.e. fishing market)

A large number of buyers and sellers exchange similar
products.
No single participant has a large influence on price (set by
supply/demand).
Firms can easily enter/leave the market.
o Monopolistic Competition (i.e. pet food market)
A large number of buyers and sellers exchange distinct and
differentiated products.
Each participant has some control over price.
A firm can begin or stop selling a good/service relatively easily.
o Oligopoly (i.e. paper/steel industries)
A few number of buyers and sellers exchange similar or
dissimilar products.
Each participant has some control over price (can result in
major losses if prices are dropped).
Start-up prices make it difficult for new firms to enter into the
industry.
o Monopoly (i.e. Google/Microsoft)
A single seller controls trade in a good or service (no close
substitutes).
Control over price in a pure monopoly is considerable.
The government regulates entry by new firms into the
industry.
o Regulated Monopoly
A firm is granted exclusive rights in a specific market by
local/provincial/federal government.
The government regulates the price.
Planned Economy: an economic system where business ownership, profits,
and resource allocation are shaped by a plan to meet government goals, not
goals set by individual firms.
Socialism: an economic system where the government owns and operates the
major industries, such as communications (private ownership existed in
industries considered less important to social welfare such as restaurants).
Communism (economic system suggested by Karl Marx): an economic
system where all property is shared equally by the people in a community
under the direction of a strong central government. The government decides
what people can buy because it controls what is produced.
Mixed Market Economy: an economic system that draws from both private
enterprise economies and planned economies (degrees vary).
Privatization: the conversion of government-owed and operated companies
to privately held businesses.
An economic system should provide:
o A stable business environment (supply meets demand, prices are
affordable and consumers have money to spend on wants/needs).
