- A.adding indirect taxes and subtracting subsidies
- B.subtracting indirect taxes and adding subsidies
- C.adding both indirect taxes and subsidies
- D.subtracting both indirect taxes and subsidies
Show answer
Correct answer: B. subtracting indirect taxes and adding subsidies
Explanation
The correct answer is B. A market price contains the indirect taxes the buyer pays, which never reach the producer, so they must be taken out. A subsidy works the other way: the producer receives it although the buyer does not pay it in the price, so it must be added back. Hence factor cost equals market price minus indirect taxes plus subsidies.
Option A reverses both adjustments and is the usual trap; it would give market price from factor cost instead. Options C and D treat taxes and subsidies in the same direction, which cannot be right, since one is a payment to the government and the other a payment from it. Factor cost is so named because it measures what the factors of production actually earn as rent, wages, interest and profit.
