PRICE ELASTICITY OF DEMAND
Price Elasticity of Demand is a measure of how much quantity demanded of
goods responds to the change in the price of that goods. It’s the percentage
change of quantity demanded divided by the percentage change of price.

PRICE ELASTICITY OF DEMAND

Price Elasticity of Demand is a measure of how much quantity demanded of goods responds to the change in the price of that goods. It’s the percentage change of quantity demanded divided by the percentage change of price. Price Elasticity of Demand = % changequantity demanded × 100 % changeprice × 100

  • With an inelastic demand curve, an increase in price leads to a decrease in quantity that is proportionately smaller. Thus, total revenue increases.
  • With an elastic demand curve, an increase in the price leads to a decrease in quantity demanded that is proportionately larger. Thus, total revenue decreases.

PRICE ELASTICITY OF SUPPLY

CROSS PRICE ELASTICITY

It is a measure of how much quantity demanded of one good responds to the change in the price of another good. It’s a percentage change in the quantity demanded of one good divided by the percentage change in the price of another good. Cross Price Elasticity = % changequantity demanded of one good × 100 % changeprice of another good × 100

LAW OF SUPPLY AND DEMAND

When there is a decrease in the price of a product, the demand for the product increases and its supply decreases. The point of intersection of the supply curve and the demand curve is known as the equilibrium point. At the price corresponding to this point, the quantity of supply is equal to the quantity of demand. Hence, this point is called the equilibrium point. Factors influencing demand
