(HOTS) Questions.

Question. Suppose your friend is indifferent to the bundles (5, 6) and (6, 6). Are the preferences of your friend monotonic?
Ans. No, the preferences of my friend are not monotonic since bundle (6, 6) should be monotonically preferred to bundle (5, 6).

Question. When a consumer is below the budget line, what does it mean?
Ans. It means that consumer is not spending his entire income.

Question. If the quantity of a commodity demanded remains unchanged as its price changes then what will be the value of price elasticity of demand?
Ans. Since change in quantity demanded (DQ) is zero, the value of elasticity of demand will be zero.

Question. What is the relation between good X and good Y in each case, if with fall in the price of X demand for good Y (i) rises and (ii) falls? Give reasons.
Ans. (i) If with fall in price of X (say, sugar) demand for good Y (say, tea) rises. Then goods X and Y are complements.
       (ii) If with fall in price of X (say, tea) demand for good Y (say, coffee) falls, then X and Y are substitutes.

Question. What do you mean by an ‘inferior good’? Give some examples.
Ans. An inferior good is one whose consumption falls with rise in income of the consumers and vice versa. For xample, low quality food items like ink coarse cereals. There is inverse relationship between income and demand.

Question. What do you mean by ‘monotonic preferences’?
Ans. Monotonic preferences:
       A consumer’s preferences are monotonic if and only if between any two bundles, the consumer prefers the bundle which has more of at least one of the goods and no less of the  other good as compared to the other bundles.
