25
Price elasticity of supply
A measure of how responsive sellers are to price changes. It measures the percent change in quantity supplied that follows from a percent price change
26
Tax on buyers
Tax shifts demand curve LEFT
27
Price ceiling
A maximum price that sellers can charge. There's a shortage of what is produced and what is demanded. *It's below the equilibrium*
28
Prices floors
If price floors bind (i.e. are above the equilibrium price), they raise prices but cause surplus
29
Mandate
A requirement to buy or sell a minimum amount of a good
30
Quota
Limit on the maximum quantity of a good that can be sold.
31
Progressive tax
A tax where those with more income tend to pay a higher share of their income in taxes
32
Regressive tax
A tax where those with less income tend to pay a higher share of their income on the tax
33
Tax expenditures
Special deductions, exemptions, or credits that lower your tax obligations, to encourage you to engage in certain kinds of activities
34
Fiscal policy
is the government’s use of spending and tax policies to influence the economy
35
Expansionary fiscal policy
Increases government spending & decreases taxes
36
Contractionary fiscal policy
Decreases government spending & increases taxes
37
Discretionary fiscal policy
Deliberate changes in government spending or taxes to boost or slow the economy on a temporary basis
38
Automatic stabilizers
Spending or tax programs that automatically adjust as the economy expands or contracts, without any need for deliberate action.
39
Gross government debt
The total accumulated amount of money the government owes
40
Net government debt
The debt that the government owes to external parties (domestic and foreign)
41
Seller's market power
The extent to which a seller can charge a higher price without losing many sales to competing businesses
42
Externality
A side effect of an activity that affects bystanders whose interests aren’t taken into account Negative: marginal social costs exceed marginal private costs --> Overproduction Positive marginal social benefits exceed marginal private benefits --> underproduction
43
Private information (negative externality)
Either the seller or the buyer have relevant information they would not want to disclose
44
Adverse selection (negative externality)
The tendency for the mix of goods to be skewed toward more low quality goods when one side of the market can’t observe quality
45
Incomplete contracts (negative externality)
Situations where some product conditions are too intricate or costly to specify
46
Irrationality (negative externality)
When people make decisions that don’t seem in their best interest
47
Time-inconsistent preferences (negative externality)
When individuals value decisions differently over time, leading to potential regret about past choices
48
Deadweight loss (DWL)
The difference between the actual level of economic surplus and the largest possible economic surplus (at the efficient quantity)
49
Marginal social cost (MSC)
The extra cost paid by the seller and bystanders from one extra unit
50
Marginal social benefit (MSB)
The extra benefit enjoyed by the buyer and bystanders from one extra unit
51
Solution to externalities
1. Corrective taxes and subsidies: designed to induce people to take account of the externalities they cause. 2. Cap-and-trade: A quantity regulation implemented by allocating a fixed number of permits, which can then be traded
52
Static games
Are always played simoulstaneosly
53
Dynamic games
Players move repeatedly or sequentially
54
Nash equilibrium
An equilibrium in which the choice that each player makes is a best response to the choices other players are making.
55
Tragedy of the commons
Tendency for common resourcesto be overutilized
56
Coordination game
Games with multiple equilibria
57
Finitely repeated game
When you face the same strategic interaction a fixed number of times
58
Indefinitely repeated game
When you face the same strategic interaction an unknown number of time
59
Folk theorem
sometimes, in indefinitely repeated games, very punitive strategies can allow players to enact collusion and maximize their pie
60
Strictly dominant strategy
Best strategy a player can choose. It wins all the time
61
Strictly dominated
Whatever the other player chooses, that stratregy always yields the worst outcome.
62
