Q

demand schedule

A

Q

movement up and down (along) a demand curve

A

shows how quantity demanded responds to a change in price.

71
Q

different between ‘quantity’ and ‘quantity demanded’

A

Demand refers to the whole demand schedule and does not change when the price of the product changes. A price change causes a change in the quantity demanded.

72

73
Q

inferior goods

A

where the quantity demanded increases as income decreases.

74

77
Q

Supply curve (S)

81
Q

extension of demand or supply

A

an increase in quantity demanded or quantity supplied.

82
Q

contraction of demand or supply

A

a decrease in the quantity demanded or quantity supplied.

83
Q

elasticity

A

a numerical measure of responsiveness of one variable following a change in another variable, ceteris paribus (with other conditions remaining the same).

84
Q

elastic

A

where the relative change in the quantity demanded is greater than the change in price, income or the prices of substitutes and complements.

85
Q

inelastic

A

where the relative change in the quantity demanded is less than the change in price, income or the prices of substitutes and complements.

86
Q

price elasticity of demand (PED)

A

measures the responsiveness of the quantity demanded for a product following a change in the price of the product.

87
Q

price elastic

A

when the relative change in the quantity demanded is greater than the change in the price of the product.

88
Q

price inelastic

A

when the relative change in quantity demanded is less than the change in price of the product.

89
Q

price elasticity of demand (PED) formula

A

PED = (% change in quantity demanded)/(% change in price).

90
Q

perfectly inelastic

A

where a change in price has no effect on the quantity demanded.
when PED = 0 (the change in the quantity demanded is equal to zero).

91
Q

perfectly elastic

A

where all that is produced is sold at a given price.
when PED = infinity (the change in the quantity demanded is equal to infinity).

92
Q

unit elasticity

A

where the change in price is relatively the same as the change in the quantity demanded.
when PED = positive or negative 1 (the change in the quantity demanded and the change in the price of a particular product are directly proportional).

93
Q

income elasticity of demand (YED)

A

measures the responsiveness of the quantity demanded for a product following a change in income.

94
Q

income elasticity of demand (YED) formula

A

YED = (% change in quantity demanded)/(% change in income)

95
Q

necessity good

A

a type of normal good with a YED that is close to zero

96
Q

superior good

A

a good with a YED greater than 1

97
Q

classification of goods in relation to income

A

For normal goods, YED is positive and expected to be between 0 and 1.
For inferior goods, YED is negative.
For necessary goods, YED is positive but is likely to be close to 0.
For superior/luxury goods, YED is positive and greater than one (looks less steep on Quantity and income graph - inverse of traditional cartesian graph for mathematics).

98
Q

cross elasticity of demand (XED)

A

measures the responsiveness of the quantity demanded for one product following a change in price of another product.

99
Q

cross elasticity of demand (XED) formula

A

XED = (% change in quantity demanded of product A)/(% change in the price of product B)

100
Q

what cross elasticity of demand (XED) indicates about two goods

A

When XED is positive, the two goods being compared are substitutes. This is because the increase in price of one good causes the other good to experience an increase in demand. This means the two goods are competitive (think Coca Cola and Pepsi). Therefore, if one is cheaper, people will buy that good over the other.
When XED is negative, the two goods being compared are substitutes. This means the two goods are complements, and are often times used together (they are ‘jointly demanded’). For example, an increase in the cost of computers might cause a decrease in the demand of computer mice or keyboards (all goods that are necessary to be used together).

101
Q

Price elasticity of supply (PES)

A

a numerical measure of the responsiveness of the quantity supplied to a change in the price of a product.

102
Q

price elastic supply

A

the quantity supplied responds more than proportionately to a change in its price.

103
Q

price inelastic supply

A

the quantity supplied responds less than proportionately to a change in its price.

104
Q

price elasticity of supply (PES) formula

A

PES = (% change in quantity supplied)/(% change in price)

105
Q

equilibrium

A

a situation where there is no tendency to change in a market.

106
Q

disequilibrium

A

a situation where demand and supply are not equal in a market.

107
Q

equilibrium price

A

the price where demand and supply are equal, where the market clears.

108
Q

equilibrium quantity

A

the amount that is traded at the equilibrium price

109
Q

changes in demand (or supply)

A

when there is a shift in the demand (supply) curve due to a change in factors other than the price of the product.

110
Q

Causes (determinants) of shifts in the demand curve

A
  • the income/ability to pay for a product
  • the price and availability of substitutes and complements (related products)
  • fashion, taste and attitudes
111
Q

Causes (determinants) of shifts in the supply curve

A
  • the costs associated with supplying the product
  • changes in the prices of other products
  • the size and nature of the industry
  • government policy
112
Q

excise duties

A

a specific tax that is levied on goods such as cigarettes.

113
Q

ad valorem tax

A

a tax that is charged as a given percentage of the price.

114
Q

The effect of time on changes in the market

A

It is a common misconception that a market responds immediately to a change in demand or supply. Time lag is an important factor when measuring demand and supply at a given point in time. The time lag period is usually a bit shorter when the market has recently experienced a change in demand compared to when it has experienced a change in supply.

115
Q

derived demand

A

where the demand for a good or service depends upon the use that can be made from it.

116
Q

A

when two items are produced together

118
Q

120
Q

incentive

A

A

the extent to which the tax burden is borne by the producer or the consumer or both (incidence of tax).
