The four factors that affect price elasticity of demand are (1) availability of substitutes, (2) if the good is a luxury or a necessity, (3) the proportion of income spent on the good, and (4) how much time has elapsed since the time the price changed. If income elasticity is positive, the good is normal.
What is a good elasticity of demand?
Demand for a good is said to be elastic when the elasticity is greater than one. A good with an elasticity of -2 has elastic demand because quantity falls twice as much as the price increase; an elasticity of -0.5 indicates inelastic demand because the quantity response is half the price increase.
What are the factors that affect elasticity of supply?
Supply elasticity is a measure of the responsiveness of an industry or a producer to changes in demand for its product. The availability of critical resources, technology innovation, and the number of competitors producing a product or service also are factors.
What is the importance of price elasticity of demand in managerial decision making?
ELASTICITY FOR MANAGERIAL DECISION MAKING It is important to know the extent to which a percentage increase in unit price will affect the demand for a product. With elastic demand, total revenue will decrease if the price is raised. With inelastic demand, however, total revenue will increase if the price is raised.
Why is the elasticity of demand so important?
It happens because rich people are not influenced much by changes in the price of goods. But, poor people are highly affected by increase or decrease in the price of goods. As a result, demand for lower income group is highly elastic. Level of price also affects the price elasticity of demand.
How does the price elasticity of a product vary?
However, the price elasticity differs for different products as it depends on various factors. Some of these factors affecting price elasticity of demand are mentioned below: The need of every individual is not the same for the same product.
Why is the demand for a commodity so inelastic?
The demand for common salt, soap, matches, ink, etc. tends to be highly inelastic, because the consumers spend a small proportion of their income on each of them. When the price of such a commodity changes, they will continue to purchase almost the same quantity of that commodity.
How does the price of a commodity affect demand?
The reason is that even a small rise in its prices will induce the buyers to go for its substitutes. For example, a rise in the price of Pepsi encourages buyers to buy Coke and vice-versa. Thus, availability of close substitutes makes the demand sensitive to change in the prices.
