Multiple choice business economics and quantitative methods government budget and economy consumer's budget public finance indifference curve

Substitution effect for a fall in the price of a commodity is given by _________.

  1. an upward shift in indifference curve

  2. an movement up of a given indifference curve

  3. a downward shift in indifference curve

  4. a movement down a given indifference curve
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In the indifference curve analysis we assume that a consumer has to choose between two goods and that his/her income is constant. If the price of either one or both the goods reduces, it means the consumer can purchase more goods. The result of an change in purchase of either good due to change in price of good with no change in income results in a substitution effect. This is the same as the income effect. This is because for normal goods both the income and substitution effect work in the same direction.

The change to a new indifference curve following a rise in aggregate consumption caused by a price cut is called the ________.

  1. consumption effect

  2. price effect

  3. income effect

  4. substitution effect
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The price effect is the total change in consumption resulting from a change in the price of a good, which encompasses both the substitution effect and the income effect.

The slope of price line is given by the ______________.

  1. taste and preferences of the consumer

  2. prices of both the commodities
  3. price of commodity $X$ alone
  4. price of commodity $Y$ alone
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The slope of price line is a ratio of prices of both the commodities 'X' and 'Y'. Thus, it is given by the prices of both the commodities.

Position of the price line would ________ with a change in the money income of the consumer.

  1. not change

  2. change

  3. depend on other factors

  4. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Position of the price line would change with change in money income of the consumer, because money income determines the budget/purchasing power of the consumer.

Multiple choice business economics and quantitative methods government budget and economy consumer's budget public finance indifference curve

Given the income of the consumer, the slope of the price line is determined by the __________.

  1. Price of $X$
  2. Price of $Y$
  3. Ratio of prices of $X$ and $Y$

  4. none of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The slope of price line is determined by the ratio of prices of both the commodities 'X' and 'Y'. It is the locus of all the bundles of 'X and Y' that can be bought with the given income of the consumer.

The total effect of a price change of a commodity is _______________.

  1. substitution effect plus price effect

  2. substitution effect plus income effect

  3. substitution effect plus demonstration effect

  4. substitution effect minus income effect
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The total effect of a price change is the sum of the substitution effect (changing relative prices) and the income effect (changing real purchasing power).

Consumer's equilibrium condition can be written as ___________.

  1. $\dfrac{MU _x}{P _x} = \dfrac{MU _y}{P _y}$
  2. $\dfrac{MU _x}{P _x} > \dfrac{MU _y}{P _y}$
  3. $\dfrac{MU _x}{P _x} < \dfrac{MU _y}{P _y}$
  4. $\dfrac{P _x}{MU _x} = \dfrac{P _y}{MU _y}$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The condition for consumer equilibrium in the case of two goods is that the marginal utility per dollar spent on each good must be equal, expressed as MUx/Px = MUy/Py.

Convex indifference curve is explained by _________.

  1. diminishing MRS

  2. increasing MRS

  3. constant MRS

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The convexity of an indifference curve toward the origin is a direct result of the diminishing marginal rate of substitution (MRS), meaning the consumer is willing to give up less of one good to get more of another as they consume more of it.

Multiple choice business economics and quantitative methods government budget and economy consumer's budget public finance indifference curve

Consumer's equilibrium occurs when __________.

  1. $MRS > \dfrac{P _x}{P _y}$
  2. $MRS = \dfrac{P _x}{P _y}$
  3. $MRS < \dfrac{P _x}{P _y}$
  4. $MRS = \dfrac{P _y}{P _x}$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Consumer equilibrium occurs at the point where the indifference curve is tangent to the budget line, meaning the slope of the indifference curve (MRS) equals the slope of the budget line (Px/Py).

For consumers' equilibrium to be stable, the requirement is __________.

  1. constant MRS

  2. increasing MRS

  3. diminishing MRS

  4. none of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

For an equilibrium to be stable and represent a maximum utility point, the indifference curve must be convex to the origin, which is characterized by a diminishing MRS.

The slope of the indifference curve is called __________.

  1. opportunity cost ratio

  2. MRTS

  3. MRS
  4. $\dfrac{P _x}{P _y}$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The slope of an indifference curve at any point is defined as the Marginal Rate of Substitution (MRS), which represents the rate at which a consumer is willing to trade one good for another while maintaining the same level of utility.

L-shaped indifference curve exists in case two goods are ____________.

  1. perfect complements

  2. perfect substitutes

  3. substitutes

  4. not related
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Perfect complements are goods that must be consumed in fixed proportions, resulting in L-shaped indifference curves where the vertex represents the optimal combination.

When indifference curve is straight downward sloping line, the two goods are _________.

  1. not related

  2. complements

  3. perfect substitutes

  4. perfect complements
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When goods are perfect substitutes, the consumer is willing to trade them at a constant rate, resulting in a straight-line indifference curve with a constant slope.
