  2. Continuous consumption
  3. No change in quantity
  4. MU of money remains constant

Q

Another name for fundamental of satisfaction is

88
Q

A

Law of diminishing marginal utility

89
Q

Consumers who does not intend to change his level of the consumption and the derives maximum satisfaction is said to be in 

A

Equilibrium

90
Q

In case of single commodity equilibrium, consumers are said to be in equilibrium only when

A

Marginal utility derived from X is the same as price of X

91
Q

what happens when marginal utility of X is more than price of X

A

When MU of X > P of X, then consumers derives more marginal utility and hence goes on consuming more units of the commodity. As he continues the marginal utility derived from each additional unit goes on decreasing due to LDMU till the time MU become is equals to P. The consumer here attains equilibrium.

92
Q

What happens when MU is less than the price of X

A

Price of commodity is more than the satisfaction derived from it. so the consumer will reduce consumption of the commodity, due to reversal law of diminishing marginal utility, satisfaction derived from the commodity will increase and consumer will attain equilibrium

93
Q

State the formula for equilibrium in one commodity case

A

MUx/ MUm = Px

94
Q

State the formula for consumers equilibrium in case of two commodities

A

MUx/ Px = MUy/ Py

95
Q

Which curve refers to the graphical representation of various alternative combinations of bundles of two goods among which the consumers in different

A

Indifference curve

96
Q

On the same in difference curve, at what point does the consumers attain maximum satisfaction

A

Every point on the indifference curve represents same level of satisfaction

97
Q

What are monotonic preferences

A

Monotonic preferences means that a rational consumer always prefers more of a commodity as it offers him a higher level of satisfaction

98
Q

More of both or more of one and no less of the other is an example of what kind of bundle

A

Monotonic preference

99
Q

The family of indifference curves that represent consumers preferences over all the bundles of two goods is called

A

Indifference map

100
Q

The slope of indifference curve is called

A

Marginal rate of substitution

101
Q

Why is the slope of indifference curve always negative

A

Because it measures the units to be sacrificed in order to gain one additional unit of another commodity

102
Q

What is the formula for MRS

A

Units to be sacrificed upon units willing to gain

103
Q

MRS is always a) increasing b) decreasing c) Constant 

A

b) 

104
Q

Is indifference curve concave or convex

A

Convex to the origin

105
Q

Why is indifference curve convex

A

Because of diminishing MRS

106
Q

Why does indifference curve slopes downwards

A

Because a consumer must consume less of one good to consume more of another good so that total satisfaction remain same

107
Q

Higher indifference curves represent higher levels of satisfaction. True or false

A

True

108
Q

Can two indifference curves ever intersect each other

A

no

109
Q

_____ is a graphical representation of all possible combinations of two goods which can be purchased with given income and prices, such that the cost of each of these combinations is equal to the money income of the consumer

A

budget line

110
Q

____ Is the set of all possible combinations of two goods which can be bought by a consumer’s income and prevailing prices in the market

A

budget set

111
Q

What is the formula of budget set

A

M = Pa * Qa + Pb * Qb

112
Q

What is your budget line called

A

Marginal rate of exchange or price ratio

113
Q

Why is the budget line a downward sloping straight line

A

Because price ratio between two commodities is always constant, hence the slope of budget line is constant, thus the budget line is a download sloping straight line

114
Q

Why is the budget line downward sloping

A

inverse relationship between commodity sacrificed and commodities gained

115
Q

What causes shift in budget line

A

Change in income or change in price of commodity

116
Q

What will happen to Budget line if income of consumer increases

A

Right word shift

117
Q

What happens to the budget line if income of the consumer decreases

A

Left word shift

118
Q

What happens to the budget line if price of good X increases

A

Budget line shift on the X axis towards the left but remains constant at the Y axis

119
Q

What happens to the budget line if commodity why becomes cheaper

A

The budget line on the Y axis moves upwards what remains the same at the X axis

120
Q

What is the condition for equilibrium in ordinal approach

A

MRSxy = Px/Py

121
Q

if MRSxy > Px/Py Then what happens

A

It means that to obtain one more unit of X the consumer is willing to sacrifice more as compared to what is required in the market. It induces the consumers to buy more of X as a result MRS falls and continues to fall till it becomes equal to the ratio of prices and equilibrium is established

122
Q

if MRSxy < Px/Py then what happens

A

when MRS is less than the price ratio then to gain more units of X the consumer is willing to sacrifice less units of Y than what is required in the market. It induces the consumer to buy less of X and more of Y. as a result MRS rises till it becomes equal to price ratio and equilibrium is established. 

123
Q

when budget line intersects IC, what is it called?

A

equilibrium

124
Q
