The marginal utility(MU) of the last unit of commodity X consumed is twice the MU of the last unit of commodity Y consumed, the consumer is in equilibrium only if:

  1. The income of the consumer is doubled

  2. The price of X is equal to the price of Y

  3. The expenditure of X is equal to twice on Y

  4. The price of Y is one half of the price of X

D Correct answer
Explanation

The Equi-Marginal Utility theory states that consumers will maximise total utility from their incomes by consuming that combination of goods where:

$\dfrac{MU _a}{MU _b} =$ $\dfrac{P _a}{P _b}$

For example, suppose bread = Re.1 and Rice = Rs.2.

  • Rice is twice as expensive as bread. Therefore, it would make sense to choose a quantity of rice, where the marginal utility of rice was twice the MU of bread. Therefore, you would tend to buy such a quantity of rice so as to make sure the marginal utility of rice justifies its higher price.
  • If rice was giving three times as much marginal utility but was only twice as expensive, it would make sense to buy more rice until the marginal utility fell to that ratio.

A Correct answer
Explanation

Diminishing marginal utility states that when a consumer goes on consuming a standard unit of a commodity, the additional utility in every successive unit of consumption keeps on diminishing. It is based on the assumption that the consumer needs to consume a standard unit of the commodity.

B Correct answer
Explanation

When the commodity consumed by a customer increases it is the normal psychological affect that the satisfaction which that commodity is providing to the customer will decrease. Therefore, for every extra unit of consumption of a commodity, marginal utility derived will decrease.

Diminishing marginal returns occurs because _____________.

  1. total output falls once too many workers are involved in the production process.

  2. as more laborers are hired, workers increasingly share use of other fixed inputs, and so their ability to be increasingly productive is limited

  3. the first laborers hired are the most qualified, but as the quantity of labor increases the firm draws from a less qualified pool of labor

  4. unemployment rates mean that qualified labour is more and more difficult to find as hiring of labour increases

A Correct answer
Explanation

Diminishing marginal returns to labour occurs when the marginal production starts to diminish with increase in the amount of labour used in the production process. This leads to increase in total production at a diminishing rate and a situation may come when the total output is maximized and then tends to fall.
