This article is about how does price elasticity affect supply and demand. Price elasticity affects supply and demand in two ways: by influencing the total revenue and the equilibrium price and quantity.
How Does Price Elasticity Affect Supply and Demand?
Price elasticity is a measure of how responsive consumers and producers are to changes in the price of a good or service. It is calculated by dividing the percentage change in quantity demanded or supplied by the percentage change in price.
Price elasticity affects supply and demand in two ways: by influencing the total revenue and the equilibrium price and quantity.
Total revenue is the amount of money that sellers receive from selling a certain quantity of a good or service. It is calculated by multiplying the price and the quantity sold. For example, if a seller sells 100 units of a product at $10 each, the total revenue is 100 x $10 = $1000.
Price elasticity affects total revenue because it determines how sensitive consumers and producers are to price changes. If demand is elastic, meaning that consumers are very responsive to price changes, then a price increase will cause a large decrease in quantity demanded and a decrease in total revenue. Conversely, if demand is inelastic, meaning that consumers are not very responsive to price changes, then a price increase will cause a small decrease in quantity demanded and an increase in total revenue. The same logic applies to supply elasticity.
Equilibrium price and quantity are the price and quantity where supply and demand are equal. They are determined by the intersection of the supply and demand curves on a graph. For example, if the supply curve is S and the demand curve is D, then the equilibrium price and quantity are P* and Q*, as shown below.
Price elasticity affects equilibrium price and quantity because it determines how steep or flat the supply and demand curves are. If demand is elastic, then the demand curve is flat, meaning that consumers are willing to buy a large range of quantities at different prices. If supply is elastic, then the supply curve is steep, meaning that producers are willing to sell a small range of quantities at different prices. The opposite is true for inelastic demand and supply.
What are the Effects of the Shift in Supply or Demand?
The elasticity of supply and demand affects how much the equilibrium price and quantity change when there is a shift in either curve. A shift in supply or demand means that there is a change in one of the factors that affect supply or demand, such as income, preferences, technology, taxes, etc. For example, if there is an increase in income, then the demand curve will shift to the right, as shown below.
The effect of a shift in supply or demand on equilibrium price and quantity depends on the elasticity of both curves. For example, if both supply and demand are elastic, then a rightward shift in demand will cause a large increase in equilibrium quantity and a small increase in equilibrium price. If both supply and demand are inelastic, then a rightward shift in demand will cause a small increase in equilibrium quantity and a large increase in equilibrium price. If one curve is elastic and the other is inelastic, then the effect will be somewhere in between.
Bottom Line
In this article, we have discussed how does price elasticity affect supply and demand. Price elasticity affects supply and demand by influencing the total revenue and the equilibrium price and quantity.
