Q

Why do governments impose excise taxes?

A
  • source of government revenue
  • a method to discourage consumption of goods that are harmful for the individual
  • can be used to redistribute income
  • a method to improve the allocation of resources (reduce allocative inefficiencies) by correcting negative externalities

Q

Why are excise taxes often imposed on goods that have a price inelastic demand (cigarettes, alcohol, petrol / gasoline)?

A

Because the lower the price elasticity of demand for a good (where PED < 1 = inelastic), the greater the government revenue generated as the product is insensitive to changes in price or income

Q

If the PED of a harmful substance is low, what affect will the addition of excise taxes have?

A

It will likely result in only a relatively small decrease in quantity demanded (because of the inverse relationship between price and demand with inelastic goods)

Q

How is redistribution of income achieved by excise taxes?

A

Income inequality is narrowed by the payment of a tax on the purchase of such luxury goods reducing after-tax income (thus narrowing differences with the incomes of lower income earners)

48
Q

How does an indirect tax effect the market’s allocation of resources (allocative efficiency)?

A

There is an under allocation of resources to the production of the good: Q + tax is less than the free market quantity, Qe

49
Q

Who are stakeholders?

A

Individuals or groups of people who have an interest in something and are affected by it, such as taxes being imposed in the market

50
Q

How can consumers be affected by indirect excise taxes?

A

They are made worse off as they are now receiving less of the good or service and paying more for it

51
Q

Why exactly are consumers worse off by indirect excise taxes in a market?

A

They are affected in two ways: by the increase in the price (from Pe to Pc), and by the decrease in the quantity they buy (from Qe to Q + tax)

52
Q

How can producers be affected by indirect excise taxes?

A

They experience a fall in their revenues, from Pe x Qe before the tax to Pp x Q + tax, and are therefore worse off as a result of the tax

53
Q

Why exactly are producers worse off by indirect excise taxes in a market?

A

They are affected in two ways: by the fall in the price they receive (from Pe to Pp), and by the fall in the quantity of output they sell (from Qe to Q + tax)

54
Q

How can the government be affected by indirect excise taxes?

A

They are the only stakeholder that gains, as their revenue is now equal to (Pc – Pp) x Q + tax instead of nothing

55
Q

How can workers be affected by indirect excise taxes?

A

They are worse off if they become unemployed, because tax may lead to some unemployment

56
Q

Why exactly are workers worse off by indirect excise taxes in a market?

A

A lower amount of output, from Qe to Q + tax, means that fewer workers are needed to produce it, leading to possible unemployment

57
Q

How can society as a whole be affected by indirect excise taxes?

A

They are worse off as a result of the tax

58
Q

Why exactly are society as a whole worse off by indirect excise taxes in a market?

A

Because there is an under allocation of resources to the production of the good (Q + tax < Qe)

59
Q

How can the equilibrium price of a demand and supply diagram be calculated from the curve functions?

A

By equalling the demand and supply functions, and solving algebraically

60
Q

How can the equilibrium quantity of a demand and supply diagram be calculated from the curve functions?

A

By substituting the calculated equilibrium price into either of the functions

61
Q

How is the P intercept of the demand function found?

A

By setting Qd = 0, and solving the equation to find P

62
Q

How is the Q intercept of the demand function found?

A

By setting P = 0, and solving the equation to find Qd

63
Q

How is the P intercept of the supply function found?

A

By setting Qs = 0, and solving the equation to find P

64
Q

How is a second point on the supply curve found, using the supply function?

A

By setting any point for Qs seen on the graph to find another coordinate with P

65
Q

How is the new supply curve, after the tax has been imposed, graphed?

A

The supply curve will shift upward by the tax amount for each level of output Q

66
Q

What is the new equilibrium price after a tax has been imposed?

A

Pc, the price paid by the consumers

67
Q

What is the new equilibrium quantity after a tax has been imposed?

A

Q + tax

68
Q

What is the new price received by the producers after a tax has been imposed?

A

Pp (= Pc – tax per unit)

69
Q

How is the new post-tax supply function found?

A

Solve for Pc and Q + tax, and then use Pp = Pc – tax per unit to find Pp

70
Q

How does the imposition of a tax, causing an upward shift of the curve by t units, change the supply function?

A

t = tax per unit, so P is replaced by P – t, resulting in the new supply function being Qs = c + d(P – t)

71
Q

How is consumer expenditure calculated, in words?

A

It is the price paid per unit of good or service multiplied by the number (quantity) purchased

72
Q

What is the formula for consumer expenditure, before and after the indirect tax?

A

Pe x Qe before, and Pc x Q + tax after

73
Q

How is producer revenue calculated, in words?

A

It is the price received per unit of good or service multiplied by the number (quantity) sold

74
Q

What is the formula for producer revenue, before and after the indirect tax?

A

Pe x Qe before, and Pp x Q + tax after

75
Q

How does producer revenue change after the indirect tax from before?

A

Firm revenue is now less than consumer expenditure (due to the occurrence of government tax revenue)

76
Q

How is government revenue calculated, in words?

A

It can be calculated in two ways: it is equal to tax per unit multiplied by the number of units sold, and it is also the difference between consumer expenditure and producer revenue after the tax

77
Q

What is the formula for government revenue, before and after the indirect tax?

A

(Pc – Pp) x Q + tax; or consumer expenditure – producer revenue after tax

78
Q

Where does the shaded area for consumer surplus appear on a diagram in a competitive free market equilibrium?

A

Above the price Pe and under the demand curve up to quantity Qe

79
Q

Where does the shaded area for producer surplus appear on a diagram in a competitive free market equilibrium?

A

Above the supply curve and un the price Pe up to Qe

80
Q

What can be said about consumer and producer surplus at the competitive free market equilibrium?

A

The sum of consumer and producer surplus, or social surplus, is maximum, indicating that allocative efficiency is achieved

81
Q

How else can allocative efficiency be indicated?

A

By MB = MC (marginal benefits equal marginal costs) at the point of equilibrium

82
Q

What happens to consumer surplus after the imposition of the tax?

A

It becomes the shaded area under the demand curve and above Pc up to Q + tax

83
Q

What happens to producer surplus after the imposition of the tax?

A

It becomes the shaded area above the original supply curve and below Pp up to Q + tax

84
Q

Why are both consumer and producer surplus reduced after a tax is imposed on a market?

A

A portion of the social surplus becomes the government tax revenue, and another portion is lost as the welfare loss triangle

85
Q

How is the government tax revenue from consumer and producer surplus used?

A

It comes back to society in the form of government spending from the tax revenues

86
Q

What is the after-tax social surplus equal to?

A

After-tax consumer and producer surplus plus government revenue

87
Q

What is the after-tax social surplus less than?

A

Pre-tax social surplus by the amount of welfare loss (deadweight loss)

88
Q

How can welfare loss (deadweight loss) be calculated?

A

(Qe – Q + tax) x (Pc – Pp) / 2

89
Q

What is welfare (deadweight) loss?

A

It represents the welfare benefits that are lost to society because resources are not allocated efficiently

90
Q

Why does a tax cause deadweight loss?

A

Because the tax causes a smaller than optimum quantity to be produced (Q + tax < Qe)

91
Q

How has the indirect tax caused a welfare loss?

A

It has caused an underproduction of the good relative to what is socially desirable, and an under allocation of resources, or allocative inefficiency

92
Q

What is occurring at the new point of production, Q + tax?

A

MB > MC, meaning that the benefits consumers receive from the last unit of the good they buy are greater than the marginal cost of producing it

93
Q

What is the welfare loss a result of?

A

Under allocation of resources to the production of the good (underproduction), which is also indicated by MB > MC; too little of the good is produced and consumed relative to the social optimum

94
Q

How is consumer surplus calculated before the imposition of an excise tax?

A

(D [MB] P intercept – Pe) x Qe / 2

95
Q

How is consumer surplus calculated after the imposition of an excise tax?

A

(D [MB] P intercept – Pc) x Q + tax / 2

96
Q

How is producer surplus calculated before the imposition of an excise tax?

A

(Pe – S1 [MC] intercept) x Qe / 2

97
Q

How is producer surplus calculated after the imposition of an excise tax?

A

(Pp – S1 [MC] intercept) x Q + tax / 2

98
Q

How is the tax burden of a good or service shared?

A

Part of the tax is paid by consumers and part by producers, therefore it is shared between the two

99
Q

Why is the tax burden shared between the consumers and producers?

A

Because compared to the pre-tax price, Pe, consumers pay a higher price (Pc > Pe), and producers receive a lower price (Pp < Pe)

100
Q

What is the burden of the tax referred to as?

A

Tax incidence

101
Q

What does the distribution of the incidence (who has the larger and smaller burden) depend on?

A

The price elasticity of demand and price elasticity of supply for the good being taxed

102
Q

How is the tax burden for consumers calculated?

A

(Pc – Pe) x Q + tax

103
Q

How is the tax burden for producers calculated?

A

(Pe – Pp) x Q + tax

104
Q

What is the distribution of the tax burden when demand is inelastic?

A

Most of the tax incidence is on consumers

105
Q

What is the distribution of the tax burden when demand is elastic?

A

Most of the tax incidence is on producers

106
Q

How is the demand curve shaped on the diagram when demand is inelastic?

A

It has a steep gradient

107
Q

How is the demand curve shaped on the diagram when demand is elastic?

A

It has a gentle gradient

108
Q

When demand is inelastic, how does equilibrium quantity change?

A

There is a relatively small drop in equilibrium quantity compared with when demand is elastic (the decrease from Qe to Q + tax is smaller)

109
Q

Why is there expected to be a smaller decrease in equilibrium quantity when demand is inelastic, as opposed to elastic, after a tax imposition?

A

Because with inelastic demand (PED < 1), quantity demanded is not very responsive to changes in price

110
Q

What is the distribution of the tax burden when supply is inelastic?

A

Most of the tax incidence is on producers

111
Q

What is the distribution of the tax burden when supply is elastic?

A

Most of the tax incidence is on consumers

112
Q

What is a simple rule to summarise the effect of PED and PES on the relative tax burden?

A

The more elastic a schedule, the more of the tax burden that will fall on the other side

113
Q

How is the supply curve shaped on the diagram when supply is inelastic?

A

It has a steep gradient

114
Q

How is the supply curve shaped on the diagram when supply is elastic?

A

It has a gentle gradient

115
Q

How is the tax burden distributed in general?

A

It falls proportionately more on the group whose activities are less responsive to price changes

116
Q

When are purchases of consumers are not very responsive to price increases?

A

When the good or service has inelastic demand

117
Q

When are sales of producers are not very responsive to price increases?

A

When the good or service has inelastic supply

118
Q

Why does the low responsiveness (low price elasticities) cause a relatively larger portion of the tax burden to consumers or producers?

A

It means that as price increases due to the imposition of the tax, consumers or producers do not change their buying and selling activities substantially
