Q1 Why is indifference curve downward sloping?

A. Indifference curve is downward sloping because when consumption of one commodity increases, the consumer has to reduce the consumption of the other commodity to remain at the same level of satisfaction.

(Note: Most of the students write this answer: Indifference curve is downward sloping because MRS declines along the indifference curve which is incorrect. MRS is the slope of indifference curve thus declining MRS only implies convexity of indifference curve.)

Q2 Classify the following into intermediate expenditure and final expenditure.
a) Expenditure on purchase of stationery by a school.
b) Expenditure on furniture purchased by a school.

A. Final goods – Final goods are those goods which are either meant for consumption of for investment during the same year.

Intermediate goods – Intermediate goods are those goods which are either used up in the production process or are for resale during the same year. Expenditure on purchase of stationery is an intermediate expenditure as stationery will be used up in the production process.

Expenditure on furniture by a school is an investment done by a school, therefore, it is a final expenditure.
