Identify the assumptions of the two - sector economy's circular flow of income.

(A) There is no trade with other countries.

(B) Households do not spend all their income.

(C) There is no government.

(D) Households do not save.

Choose the correct answer from the options given below:

Solution

✅ Correct Option: 1

Option 1 -> Includes assumptions (A), (C), and (D) which correctly represent a two-sector economy where there's no foreign trade, no government, and households spend all income without saving.

Option 2 -> Incorrect because (B) contradicts the two-sector model assumption; households must spend all income in this simplified model.

Option 3 -> Incorrect because (B) contradicts the basic assumption that households spend all their income in a two-sector economy.

Option 4 -> Incorrect because it excludes (A) which is a fundamental assumption, and includes (B) which is wrong for a two-sector model.


Hence, Option 1: (A), (C) and (D) only -> In a two-sector circular flow model, the economy consists of only households and firms. The key assumptions are: (A) No international trade - there's no foreign sector; (C) No government - no government intervention, taxes, or spending; (D) Households do not save - all income earned is spent on consumption, ensuring continuous circular flow without leakages. Statement (B) is incorrect because it suggests households save, which contradicts the fundamental assumption that all income circulates back to firms through consumption expenditure. -> correct
