Which of the following is NOT a determinant of demand for a commodity?
(a) Price of the commodity
(b) Income of the consumer
(c) Cost of production of the commodity
(d) Price of related goods

Question

Accepted Answer

Demand is shaped by factors on the buyer's side: the commodity's own price, the buyer's income, the prices of related (substitute or complementary) goods, tastes and preferences, expectations of future prices, population, and government policy such as taxes or subsidies — options (a), (b) and (d) are all standard determinants of demand for exactly this reason. Cost of production, however, is a factor that determines how much a producer is willing to supply at a given price — it affects the supply curve, not the demand curve; a rise in the cost of producing a good does not, by itself, change how much a buyer wants to purchase at a given price. This is why (c) is the correct answer to 'NOT a determinant of demand' — it belongs on the supply side of the market, covered separately under Supply Analysis.

✓Final answer

(c) Cost of production of the commodity — it is a determinant of supply, not of demand.

$Q. Find the odd word: Determinants of demand: Income, Cost of production, Size of population, Price$
›Reveal solutionSolution
Odd word = Cost of production.

The determinants of demand are the factors that influence how much of a good consumers wish to buy:

Price of the commodity itself.

Income of the consumer.

Size of population (more people, more demand).

Cost of production affects how much producers are willing and able to supply, not how much buyers demand, so it is a determinant of supply — making it the odd word.

✓Final answer
$Odd word: Cost of production .$

$Q. Give an economic term: A desire which is backed by willingness to purchase and ability to pay.$
›Reveal solutionSolution

The economic term is Demand.

A plain desire or wish for a good is not 'demand' in economics. Demand exists only when three things come together: a desire for the commodity, the willingness to buy it, and the ability to pay its price. If any one is missing — for example, a poor person wanting a car has the desire but no purchasing power — it stays a mere want, not demand. Demand is always stated with reference to a particular price and a particular period of time.

✓Final answer
$Demand — a desire for a commodity backed by willingness to purchase and the ability to pay for it.$

$Q. Give an economic term: A desire which is backed by willingness to purchase and ability to pay.$
›Reveal solutionSolution
The term described is Demand — a desire for a commodity supported by both the willingness to buy it and the ability to pay for it.

A plain wish for a good is only a desire or want. Economics treats it as demand only when three conditions are met together:

Desire for the commodity,

Willingness to purchase it, and

Ability to pay (purchasing power) at the given price.

When all three combine, the want becomes effective demand — the quantity a consumer is willing and able to buy at a given price and time.

✓Final answer
$Economic term: Demand .$
