Econ Exam #2 (Micro) Flashcards
Price Controls, Taxes, Welfare; Public Goods; Externalities; and Poverty, Information, and Insurance/Risk
What are prices?
Prices are signals that guide the allocation of society’s resources.
What is Michael Sandel’s theory about price regulation?
Once a good’s price changes the good’s ethical and moral standards, the good should no longer be able to hold a price value. Ex: human life, organ donation, good grades in school, citizenship are things people obtain without having to be/get paid. Once these goods/services get priced, the work it took to get them are no longer valued the same.
What is the difference between Market Economies and Societies?
Market Economy uses markets to organize allocated resources while Market Society is a world where everything is for sale/has a price.
What are the two main Government Policies that alter the private market outcome?
Price Controls (ceilings/floors) and Taxes
What is a Price Ceiling? Give a common example.
Legal Maximum & Apartment Rent
What is a Price Floor? Give a common example.
Legal Minimum & Minimum wage
What are Taxes?
Buyers and sellers pay a specific amount on each unit bought/sold.
How do Price Ceilings affect market outcomes?
PCs act as binding constraints below the equilibrium and create shortages in the market.
What is the issue with shortages and rationing?
Who gets what? There are rationing mechanisms like lines and lotteries; however, these often fail due to discrimination, unfair treatment, and inefficient goods going to the highest value user.
True or False: Prices as the rationing mechanism “work.”
True
How do Price Floors affect market outcomes?
PFs act as binding constraints above the equilibrium and create surpluses in the market. For ex: price floors in the market for unskilled workers often leads to a labor surplus (unemployment) due to more labor needed than demanded.
Why do governments levy taxes on many goods & services?
To raise revenue for goods like national defense, public schools, etc.
Who can be taxed?
Buyers or sellers.
How can good’s be taxed monetarily?
The tax can be a percentage of the good’s price or a specific amount for each unit sold (per-unit).
What does a tax on buyers do to the demand curve?
A tax on buyers shifts the demand curve down by the amount of the tax.
What is the Tax Incidence?
The TI is a measurement of how the burden of tax is shared.
What does a tax on sellers do to the price of a good/service?
A tax on sellers makes the price of G/S more expensive for the same quantity.
How do taxes affect prices differences between buyers and sellers?
A tax drives a wedge between the price buyers pay and the price sellers receive.
Who will bear the burden of a tax?
This answer depends on how responsive buyers and sellers are to a price change. Responsiveness = elasticity for economists.
What do different elasticity curves look like?
Relatively inelastic curves are steep and short in change. On the other relatively elastic curves are flatter in nature and longer wider in change.
Who bears more of a burden when inelasticity of demand is higher than the inelasticity of supply?
The buyer
True or False: Supply is steeper/less elastic than demand.
False - Supply is flatter/more elastic than demand.
Who bears the bigger burden when supply is more inelastic than demand?
The sellers
What is Welfare economics?
WE is the study of how the allocation of resources affects economic well-being.
What are the three main aspects of welfare economics? (CPTS)
Consumer, Producer, and Total surplus
What is WTP?
The willingness to pay is the maximum amount the buyer will pay for a given quantity.
What does WTP measure?
The WTP measures buyers’ “value” in a good/service (satisfaction/utility).
What is Consumer Surplus (CS)?
CS is the amount a buyer is willing to pay minus what the buyer actually pays.
CS = WTP - P where P is price paid.
CS Example:
Suppose WTP = $90
Suppose P = $80
What is the consumer surplus?
CS = $90-$80 = $10 added benefit
Where is CS in relation to the demand curve?
CS is the area BELOW the demand curve and ABOVE the price.
Formula: A = 1/2 (base x height)
CS Graph Example
WTP = $60
P = $30
Quantity at P = 15
What is the consumer surplus?
CS = ((60-30) x 15) x 1/2
CS = $225 net benefit
How do price changes affect CS?
Some area from producer surplus transfers to consumer surplus as additional cs to initial customers. Additionally, cs to new consumers (from more demand) is added.
What is Cost?
Cost is the value of everything a seller must give up to produce a good (opp costs).
True or False: A seller will only produce and sell the good if the P is equal to or more than the cost.
True
What is Producer Surplus (PS)?
PS is the amount a seller is paid for a good minus the seller’s cost.
PS = P - Cost
where P is price paid
PS Example
Suppose P = $40
Seller’s Cost = $30
Q = 15
PS = $40-$30 = $10 of producer benefits
PS Graph Example
P = $40
S = $15
Q = 25
PS = ((40-15) x 25) x 1/2
PS = $312.50 of producer benefits
How do price changes affect PS?
Some consumer surplus transfers to producer surplus when the price changes. This is known as the additional producer surplus to initial producers. Additionally, more producer surplus available from greater supply is from new producers.
What do CS, PS, and TS measure?
CS = value to buyers - amount paid
PS = amount paid - cost to seller
TS = CS + PS
True or False: The market outcome if inefficient.
False
What is efficient or inefficient compared to the market equilibrium?
Do not make amount more than the equilibrium as they are inefficient.
Continue to make amount less than the equilibrium until they reach PE as this is efficient production.
True or False: The government cannot raise total surplus in a competitive market.
True. If you produce less or more there is less surplus. Max surplus is the best outcome and no one can change it.
What is Laissez faire?
Literally allow them to do.
This is the notion that government should not interfere with market.
What is deadweight loss?
Goods that could be made but shouldn’t be.
True or False: More elasticity means more deadweight loss.
True
What happens when tax is doubled?
The DWL increases by roughly 4 times, and the revenue begins to decrease! This proves the law of demand.
True or False: Higher taxes guarantee higher revenue.
False: high taxes do NOT guarantee higher revenue. In fact, the higher up the tax reaches, the more revenue lost from the original tax-enforcer. This is also due to the law of demand.
What goods can be consumed without payment?
Public goods, like parks, national defense, clean air, and water are all provided by the government.
What are the important characteristics of goods?
Excludability: a person can be prevented from using a good
Rivalry in Consumption: one person’s use diminishes others usage
What happens to private decisions when markets do not “work?”
inefficient outcomes
What are the characteristics of private goods? Provide examples.
Rivalrous and excludable (pizza, latte, etc.)
What are the characteristics of club goods/natural monopoly? Provide examples.
Excludable and non-rivalrous (cable tv, fire protection, etc.)
