How is economic efficiency defined in Principles of Micro

A

an economy is efficient if all opportunities to make some people better off without making other people worse off have been exhausted

under perfect competition automatically maximizes social welfare, or total economic surplus

76
Q

what does increasing returns to scale yield

A

economies of scale, fewer inputs are needed per unit of output as sale increases, reducing average cost

77
Q

what does decreasing returns to scale yield

A

diseconomies of scale, more inputs are needed per unit of output as scale increases, increasing average cost

A

marginal cost for providing the public good should equal the sum of the private marginal benefits

81
Q

what does a Pigouvian tax to correct negative externalities do

A

causes market participants to “internalize” the externality

t=MEC(Qso)

82
Q

non-renewable resource meaning

A

mineral and fossil fuel resources found in finite supply in the earth’s crust; there is a fixed stock of the resource

83
Q

current reserves meaning

A

known stock of the resource that can profitably extracted at current prices

84
Q

potential reserves

A

stock of the resource that may become profitably extractable if prices rise high enough

85
Q

undiscovered reserves

A

unspecified deposits of mineral-bearing material believed to exist on the basis of geological data and theory

86
Q

resource endowment

A

the natural occurrence of resources within a country or region

87
Q

marginal user cost definition

A

opportunity cost of extracting/ using a resource today, which is that it will not be available to use in future

88
Q

what is a backstop resource

A

a substitute for depletable resource

89
Q

when does a backstop resource begin being consumed

A

at the point where the total marginal cost of extracting the depletable resource exceeds the marginal cost of producing the backstop resource

90
Q

what are external costs

A

costs not account for by either the marginal production or user costs

91
Q

how do external costs affect the switching time to a backstop resource

A

switching point would come sooner

92
Q

what is the theory of endogenous risk

A

in which the probabilities of different outcomes are themselves affected by the choices we make

93
Q

is oil a renewable resource?

A

No, it is considered non-renewable because it is not regenerated in the earth’s crust at a rate fast enough to keep up with current rate of human consumption

94
Q

what is absolute scarcity

A

finite amount of oil resources available, therefore if we keep using it we will run out

95
Q

what is relative scacity

A

as oil becomes relatively more scare than other resources, its price will rise, incentivizing us to adapt in various ways

1942 - 1978 Wellhead Price Controls

A

4 rationales for wellhead price controls
- need for comprehensive regulatory framework
- anti-competitive behavior of oil companies
-lack of competition in natural gas production markets
- a shift of price differential rents from producers to consumers

FPC ruled that sales from producers to affiliated interstate pipelines would be subject to federal oversight

108
Q

A

Supreme Court decision required FPC to begin regulating wellhead prices on all field sales

109
Q

1978 Natural Gas Policy Act

110
Q

Benefit of 1978 Natural Gas policy Act

A

-market demand did not increase as much as predicted
-addition of new customers to pipeline and utility delivery networks
-interstate gas supplies increased by more than increase in production

111
Q

Consequences of partial wellhead price decontrol

A

new contracts negotiated prices that were still too high to be supported by the market, resulting in excess supply

112
Q

Name of pricing structure for Gas pipelines

A

two-part tariff

113
Q

description of two-part tariff for gas pipelines

A

firm customers subscribe to a portion of the pipelines capacity

fixed monthly fee per unit of subscribed capacity (called an access or reservation fee)

variable charge per unit of gas shipped (usage charge)

both are regulated

114
Q

spot price arbitrage

A

implies difference between the Hub and City gate spot price must equal the transportation charge

115
Q

the ship gas or release it to other shippers to use

unregulated transportation charge from this
