Q1 :

What are monotonic preferences ?


Answer :

It means that the consumer prefers a particular bundle over the other bundle if the former consists of at least more of one good and no less of the other good.
Example:
If bundle A(3, 5) and bundle B(3, 2) are available to the consumer, then he/she will prefer bundle A over bundle B as bundle A consists of more units of good 2 than bundle B.

Q2 :

If with the rise in price of good Y, demand for good X rises, the two goods are : (Choose the correct alternative)
(a) Substitutes
(b) Complements
(c) Not related
(d) Jointly demanded


Answer :

If with the rise in price of good Y, demand for good X rises, the two goods are said to be substitutes. This is because substitute goods are the ones which are consumed in place of each other. For instance, tea and coffee. Thus, if the price of one good rises, the demand for other substitute good will rise.
Hence, the correct answer is option (a).

Q3 :

Define budget line.


Answer :

A budget line represents the different combinations of two goods that are affordable and are available to a consumer; while being aware of his/her income-level and market prices of both the goods. The budget line is represented by the following equation.

P1x1 + P2x2 = M
