Define economics
The study of how people seek to satisfy their needs and wants by making choices
Explain how scarcity relates to economics
Scarcity is that there are limited quantities of resources
to meet unlimited wants
What is opportunity costs?
The most desirable alternative given up as the result of a
decision
What are trade offs
An alternative that is sacrificed when a decision is made
Define factors of production
Resources that are used to make all goods and services
What are the three factors of production?
Land, labor, & capital
Define consumer sovereignty
Is the power of consumers to decide what gets produced
What is self interest?
Means that buyers and sellers are focused on personal gain
What is competition?
The struggle among producers for the dollars of consumers
What is incentive?
For consumers is the hope of reward or the fear of punishment that encourages people to behave
in a certain way; incentives for business is selling more goods for
more profit
What is laissez faire?
The doctrine that states the government generally should not
intervene in the marketplace
What is consumer sovereignty?
Is that consumers decide what gets produced because businesses want
to meet the consumers desires
What are the five features of a market
economy? (capitalism)
1. Self interest2. Competition
3. Incentive4. Laissez faire
5. Consumer sovereignty
What are the benefits of a market economy?
Incentives to produce,Greater efficiency
Private ownership & innovation
What are the costs of a market economy?
More varied income,Unemployment
Poverty/homelessness, wealth gap
Describe Adam Smith
Believed that in each transaction, the buyer and seller consider
their self interest or personal gain
Describe Karl Marx
Believed that human labor was the source of all added value but keeps it as profit or exploiting the
workers
Describe John Maynard Keynes
Believed that government intervention may be needed in crisis situations to pull the economy out of depression
(pump money into the economy)
What is sole proprietorship?
A business owned and managed by a singled
individual
What is a partnership?
Owned by two or more persons who agree on specific
responsibilities
What is a corporation?
Owned by individual stockholders and run by a
board of directors
What is the role of stockholders in financing
corporations?Stockholders must invest money to buy
shares to finance and to part of the corporation. They are considered the
owners
What is the role of government in
regulation corporations?To make sure the corporations follow the
regulations they set such as filing quarterly and annual reports to the SEC
and taxation
Define the law of demand
Consumers buy more of a good when its price decreases and
less when it increases
Define the law of supply
The tendency of suppliers to offer more of a good at a higher
price
Describe perfect competition
Is when a large number of firms all produce the same product
Describe monopoly
A system that is dominated by a single seller
Describe monopolistic competition
When many companies sell products that are similar but
not identical
Describe oligopoly
Is when a fes large firms dominate a market
Define elasticity of demand
Is a measure of how consumers react to a change in price
Define elastic demand
Very sensitive to change in priceEx: the demand for a particular
brand
Define inelastic demand
Not sensitive to change in priceEx: goods with no substitutes-
water, gas, utilities
Define unitary demand
Is a demand whose elasticity is equal to 1
Ex: equilibrium
Define price floor
A government- or group-imposed limit on how low a price can be
charged for a product. For a price floor to be effective, it must be
greater than the equilibrium price
What is price ceiling?
It’s a government-imposed limit on the price charged for a
product
What is total cost?
Fixed costs plus variable costsEx: materials and labor
Define fixed cost
Is a cost that does not changeEx: rent mortgage
Define variable cost
May rise of fall depending on the quantity produced
Ex: raw materials
Define marginal cost
It is the cost of producing one more unity of a good
Ex: hiring a new worker
What is the golden rule of profit maximization?
Occurs at a point where marginal costs equals marginal revenue.
Thus, the optimal level of production occurs where marginal revenue equals marginal costs, the point of maximum profit as dictated by the golden rule
