Q

when supply or demand is inelastic, it is (harder/easier) to leave the market when the tax reduces Ps so the DWL is (small/large) since the Q reduces a (little/lot)

A

harder; small; little

25
when supply or demand is elastic, it is (harder/easier) to leave the market when the tax reduces Ps so the greater Q falls below the surplus-maximizing quantity, the (greater/lesser) the DWL
easier; greater
26
doubling the tax causes the DWL to ? and tripling it causes the DWL to ?; so, when a tax increases, DWL ?
more than double/triple; rises even more (right half of a parabola)
27
the Laffer curve
shows the relationship between the size of the tax and tax revenue (-x^2)
28
the world price of a good is the
price that prevails in world markets
29
if Pd < Pw
country has comparative advantage in the good; exports
30
if Pd > Pw
country does not have comparative advantage; imports
31
tariff
a tax on imports
32
arguments for restricting trade
1. jobs 2. national security 3. infant-industry 4. unfair-competition 5. protection-as-bargaining-chip
33
the jobs argument
Trade destroys jobs in industries that compete | with imports.
34
the national security argument
An industry vital to national security should be protected from foreign competition, to prevent dependence on imports that could be disrupted during wartime.
35
the infant-industry argument
A new industry argues for temporary protection until it is mature and can compete with foreign firms.
36
the unfair-competition argument
Producers argue their competitors in another country have an unfair advantage, e.g. due to govt subsidies.
37
the protection-as-a-bargaining-chip argument
Example: The U.S. can threaten to limit imports of French wine unless France lifts their quotas on American beef.
38
trade agreements
a country can liberalize trade with unilateral reductions in trade restrictions and multilateral agreements with other nations (ex: NAFTA, GATT, WTO)
39
a tariff benefits ? and generates revenue for the government, but the losses to consumers (does not exceed/exceeds) these gains
producers; exceeds
40
if a country exports, trade
raises producer surplus, reduces consumer surplus, and raises total surplus
41
if a country imports, trade
reduces producer surplus, raises consumer surplus and total surplus
42
externality
one type of market failure; the uncompensated impact of one person's actions on the well-being of a bystander; can be negative or positive
43
examples of negative externalities:
air pollution from a factory, neighbor's barking dog, health risk to others from second-hand smoke, etc.
44
private cost
the cost directly incurred by sellers
45
private value
the value to buyers (WTP)
46
social cost
private + external cost
47
external cost
value of the negative impact on bystanders
48
internalizing the externality
altering incentives so that people take account of the external effects of their actions (ex: introduce a tax)
49
examples of positive externalities:
vaccination, going to college
50
in the presence of a positive externality, social value includes
private value (direct value to buyers) and external benefit (the value of the positive impact on bystanders)
51
two approaches to public policies toward externalities
1. command-and-control (regulate behavior directly: ex - limits on quantity of pollution emitted) 2. market-based policies (provide incentives so that private decision-makers will choose to solve the problem on their own: ex - corrective taxes/subsidies and tradable pollution permits)
52
corrective tax
a tax designed to induce private decision-makers to take account of the social costs that arise from a negative externality (AKA Pigouvian taxes)
53
the ideal corrective tax is the ? or (for activities with positive externalities) ?
external cost, external benefit
54
are corrective taxes or regulations better?
corrective taxes
55
with tradable pollution permits, firms with a low cost of reducing pollution ? and firms with high cost of reducing pollution ?
do so and sell their unused permits, buy permits
56
the Coase theorem
if private parties can costlessly bargain over the allocation of resources, they can solve the externalities problem on their own
57
why do private solutions not always work?
1. transaction costs (the costs parties incur in the process of agreeing to and following thru on a bargain - may make it impossible to reach a mutually beneficial agreement) 2. stubbornness (even if a beneficial agreement is possible, each party may hold out for a better deal) 3. coordination problems (if the number of parties is very large, coordinating them may be costly, difficult, or impossible)
58
a good is excludable if
a person can be prevented from using it (ex: fish tacos, wireless Internet access)
59
a good is NOT excludable if
a person cannot be prevented from using it (ex: AM/FM radio signals, national defense)
60
a good is rival in consumption if
one person's use of it diminishes others' use (ex: fish tacos)
61
a good is NOT rival in consumption if
one person's use of it does not diminish others' use (ex: an MP3 file of Lady Gaga's latest single)
62
What are the four different kinds of goods?
1. private goods 2. public goods 3. common resources 4. club goods
63
private goods + ex
excludable, rival in consumption (ex: food)
64
public goods + ex
not excludable, not rival (ex: national defense)
65
common resources + ex
rival but not excludable (ex: fish in the ocean)
66
club goods + ex
excludable but not rival (ex: cable TV)
67
public goods are difficult for private markets to provide because of the ? problem
free-rider (a person who receives the benefit of a good but avoids paying for it)
68
if the benefit of a public good exceeds the cost of providing it, gov't should (not provide/provide) the good and pay for it with a tax on people who benefit
provide
69
cost-benefit analysis
a study that compares the costs and benefits of providing a public good (imprecise)
70
the tragedy of the commons
when common resources get used more than is socially desirable
