Consumer Surplus |
The difference between the highest price a consumer is willing to pay for a good or service and the actual price the consumer receives Willing-Actual = CS 6-3.50 = 2.50 is CS |
|
Producer surplus |
The difference between the lowest price firm would be willing to accept for a good or service and the price it actually receives |
|
When a government imposes a price ceiling or floor the amount of economic surplus in a market is... |
Reduced |
|
How do you measure the total consumer surplus in a market |
The demand curve |
|
Demand curve |
A graph that shows the willingness of consumers to purchase a product at different prices |
|
Supply curve |
A graph showing the willingness of firms to supply a product |
|
Marginal cost does what if more of the good is produced in a given time period |
Increases |
|
Output is efficient when |
Where all the marginal benefit exceeds the marginal cost Maximizes the sum of consumer and producer surplus |
|
Consumer surplus + producer surplus = economic surplus |
At competitive equilibrium the ES is maximized |
|
Deadweight lost |
The reduction of economic surplus resulting from a market not being in competitive equilibrium In a competitive equilibrium deadweight lost is zero The inefficiency in a market place B+C |
|
Price ceiling |
Legally determined maximum price sellers can charge |
|
Price floor |
Legally determined minimum price that sellers may receive |
|
Triangle area formula for consumer and producer surplus |
Area= 1/2 (base) (height) |
|
When a government taxes will more or less of the good be produced |
Less |
|
Tax incidence |
The division of the burden of a tax between buyers and sellers |
|
Externality |
A benefit or cost that affects someone who is not directly involved in the production or consumption of a good or service They interfere with economic efficiency A side effect |
|
Private cost |
Cost borne by the producer of a good or service |
|
social cost |
Total cost of producing a good or service Social cost = private cost + externalities |
|
Private Benefit |
The benefit received by the consumer for the good or service |
|
Social benefit |
The total benefit from consuming a good or service Social benefit = private benefit + external benefit |
|
Market failure |
Situations in which the market fails to produce the efficient level of output |
|
Property right |
The rights individuals or businesses have to the exclusive use of their property |
|
What do good property right do |
They avoid market failure |
|
What is a result of incomplete property rights |
Externalities |
|
Coase theorem |
If transaction costs are low private bargaining will result in an efficient solution to the problem of externalities |
|
Transaction costs |
The cost in time and other resources that parties incur in the process of agreeing to and carrying out an exchange of goods and services |
|
Subsidy |
An amount paid to producers or consumers to encourage the production or consumption of a good |
|
Pigovian taxes |
Increase efficiency while bringing in tax revenue Using government tax and subsidy to bring about an efficient level of output in the presence of externalities |
|
Rivalry |
The situation that occurs when one persons consuming a unit of a good means no one else can consume it |
|
Excludability |
The situation in which anyone who does not pay for a good cannot consume it |
|
4 Categories |
Private goods Public goods Quasi-public goods Common resources |
|
Private good |
A good that is both a rival and excludable |
|
Public good |
Both non-rival and non-excludable National defence |
|
Quasi-public good |
Some goods are excludable but not rival Cable |
|
Common resources |
A good is rival but not excludable Forest land |
|
Market demand curve for private good |
Add horizontally the quantity of the good at each price by the consumer |
|
Demand curve for a public good |
Add the price at which each consumer is willing to ourchase each quantity of the good |
|
Price elasticity of Demand |
It is more useful to have a measure of the responsiveness of the quantity demanded to a change in price |
|
Price elasticity of demand |
Quantity demanded changes a lot in response to a price change PED= percentage change in quantity demanded/ percentage change in price Elastic: if PED Is larger than -1 Inelastic: if PED is smaller than -1 Unit price elastic: if PED equals -1 |
|
To calculate price elasticity |
1. Average quantity and price 2. Calculate percentage change in Q and P (Q2-Q1/avg) (P2-P1/avg) x 100% 3. Percentage change of Q/P |
|
A vertical demand curve is |
Perfectly inelastic |
|
A horizontal demand curve is |
Perfectly elastic |
|
Determinatives of PED |
1. The availability of close substitutes 2. The passage of time 3. Wether the good is luxury or necessity 4. Definition of the market 5. The share of a good in consumer budget |
|
Is elasticity-constant |
No |
|
Norman and necessity products elasticity |
Positive but less than 1 |
|
Normal and luxury elasticity |
Positive and greater than 1 |
|
Inferior product in elasticity |
Negative |
