in a country with large population of full-time housewives, national income

Analyze the question: The question asks how a large population of full-time housewives affects the measurement of national income.

Concept: National income is the total value of goods and services produced in a country over a period, usually a year. It counts only output that is paid for or exchanged in the market (recorded transactions). Services that are not sold, such as housework, cooking, childcare, and caring for the family, carry no market price. They are therefore not included in national income accounts, even though they are real productive activities.

Solution:

• Full-time housewives do valuable work: cooking, cleaning, child-rearing, and caring for the sick and elderly.
• This work is unpaid, so it is not recorded in official statistics.
• If many people do this work, a large amount of real economic activity is left out of the calculation.
• As a result, the measured national income is lower than the true value of output, so the figures are under-stated.

Checking the options:

• A. Wrong. Nothing suggests national income is made up only of goods produced by women.
• B. Wrong. Over-statement would mean counting too much, but here output is left out.
• C. Not the best answer. Calculation may be hard in general, but the specific effect of unpaid housework is under-estimation.
• D. Correct. Unpaid household services are excluded, so national income is grossly under-stated.

Tip: Remember the rule "No payment, no counting." Unpaid housework, subsistence farming for one's own use, and voluntary services are left out of national income, which leads to under-statement. In exams, "housewives" or "unpaid services" usually points to under-stated national income.
