Elasticity is a measure of how responsive a market price is to changes in demand or supply. It tells us how quickly the price changes when there is a change in either the quantity demanded or supplied.
Elasticity = (% change in price) / (% change in quantity)
For example, if the price of a good rises by 5% when the quantity demanded falls by 10%, then the elasticity is calculated as:
Elasticity = -0.2/0.1 = -2
This means that the price changes significantly in response to changes in demand.
Applications of elasticity:
Demand and supply: Elasticity can be used to analyze the relationship between supply and demand in a market. A price increase will typically lead to a decrease in demand, while an increase in price will lead to an increase in demand.
Price discrimination: Elasticity can be used to determine whether a company should price discriminate between different segments of the market.
Tax policy: Elasticity can be used to determine how a tax policy will affect the price of a good or service.
Additional points:
Elasticity can be positive or negative. A positive elasticity indicates that the price changes more than proportionally to changes in demand or supply. A negative elasticity indicates that the price changes less than proportionally to changes in demand or supply.
Many factors can influence elasticity, including the availability of substitutes, the degree of market competition, and the cost of producing the good.
Elasticity is a complex topic, and there are many different factors that can affect it. However, understanding elasticity can help us to better understand how markets work and how to make better economic decisions
