Supply and Demand


Demand edit

Demand for a commodity refers to a desire backed by a necessary purchasing power. By demand we mean the various quantities of a given commodity or the services of the consumer which consumers would buy in one marketing at a given period of time at various prices or at various prices of the related goods.

Thus demand is not a mere desire but desire with the capacity and willingness to purchase. It is always related to price and should be referred to per unit of time. Demand arises for a commodity with variations in income and variations in price of related goods.

Law Of Demand edit

The Law Of Demand states that, "The greater the amount to be sold the smaller must be the price at which it is offered in order that it may find at purchasers or in other words the amount demanded increases with a fall in price & diminishes with a rise in price".

Factors Influencing Demand edit

  2. Demand depends on tastes, preferences, customs & habits of the consumers.
  3. Existence of substitutes for a commodity will affect it's demand.
  4. Expectations of the consumer about the future will also alter the demand.
