Meaning Of Demand And Factors Affecting Demand

Demand is the number of goods that the customers are ready and able to buy at several prices during a given time frame. The association between price and quantity demanded is also called a Demand curve. Preferences and choices, which are the basics of demand, can be depicted as the functions of cost, odds, benefit and other variables.

The amount of a good that the customer picks up modestly, relies on the cost of the commodity, the cost of other commodities, the customer’s earnings and his or her tastes and proclivity. The amount of a commodity that a customer is ready to purchase and is able to manage and afford, provided prices of goods and customer’s tastes and preferences are known as demand for the commodity.

In our daily life, we often see that a consumer’s preferences for product change according to their preferences, income, and the prices of the goods or prices of other goods.

Here, the demand of a product can be defined as the quantity of a product that a consumer is eager to purchase, can afford at a given price, and is according to his/her preferences and taste. Whenever there is a change in any of those variables than the demand and supply of a product starts changing.

Types of Demand

  • Market or Individual Demand- Here, the individual demand is defined as the demand for products or services by an individual consumer. And the market demand can be defined as a demand for a product made by a bunch of consumers who buy that product. Therefore, the market demand is a collective demand of each individual’s demand.
  • Director Derived Demand: The direct demand is defined when goods manufactured is related to the demand for another product is known as the derived demand. For example; the demand for a silk yarn is the result of the demand for silk cloth. However, direct demand for goods can be defined when the demand for a product is independent. For example, there is an autonomous demand for cotton cloth.
  • Price Demand- The price demand refers to the number of goods or services an individual is eager to buy at a given price.
  • Income Demand- The income demand means the eagerness of a person to buy a definite quantity at a given income level.
  • Cross Demand: This is one of the important types of demand where the demand of a product is not subject to its own price, but the price of other similar products is known as the cross demand.

6 Marks Question
Q.1 Define demand. Explain any four important factors that affect the demand for a commodity.
Answer:
(A) Definition of demand
  • Demand may be defined as the quantity of a commodity that a consumer is able and willing to buy, at each possible price, over a given period of time.
  • Essential elements of demand are Quantity, Ability & Willingness, Prices and period of time.
(B) Following are the important factors that affect the demand of a commodity:
(a) Own price of the given commodity [Pi20 Car  Di20 Car] [Pi20 Car Di20 Car]…Inverse Relation

  • Own price is the most important determinant of demand.
  • When own price of a commodity falls, its demand rises and when own price rises, its demand falls.
  • Thus we can say that there is an indirect relation between the price of a commodity and its quantity demanded.
(b) Price of related goods Substitute Goods [PMaruti Swift Di20 Car]…Direct Relation

Complementary Goods [PPetrolDi20 Car]…Inverse Relation

RELATED GOODS ARE OF TWO TYPES – SUBSTITUTE AND COMPLEMENTARY

(i) SUBSTITUTE GOODS

  • When the price of the substitute goods rises then demand the given commodity also rises and vice-versa.
  • Like, if Price of Maruti Swift increases, demand for i20 will rise.

(ii) COMPLEMENTARY GOODS

  • (Car & Petrol) When the price of the complementary goods rises then demand the given commodity falls and vice versa.
  • Like, if the price of petrol rises, demand for cars fall.
(c) The income of the consumer [IncomeHouseholdDNormal Goods]…Direct Relation

[IncomeHouseholdDInferior Goods]…Inverse Relation

  • To check the effect of change in income of the households over their demand, goods are divided into two categories:

(i) Normal Goods (Positive relation)

These are the goods whose demand rises with the rise in income. E.g. Basmati Rise

(ii) Inferior Goods (Negative relation)

These are the goods whose demand falls with the rise in income and vice versa. e.g. Low-quality rice.

(iii) Necessities:

A third category is also there, necessities, demand for these generally does not change with change in income e.g. life-saving drugs.

(d) Taste and preferences of the consumer
  • Demand for a commodity is also affected by taste and preferences.
  • It rises if there is a favourable change in the taste and preferences of the consumer and vice versa.
(e) Miscellaneous
  • Future expectation about price and income also affect the demand for a commodity is present.
  • Suppose, if we expect a rise in price in the near future, then we’ll increase demand in present even at the same price.
