make a detail comparison between demand and supply curves and elasticity and elasticity curves .
Hi,
Hope you are doing well!
Question:
Answer:
Demand Curve:
The demand curve is a graphical representation of the relationship between the price of a good or service and the quantity demanded for a given period of time. Price and the quantity demanded for a good or service have a reverse relationship or move together in the opposite direction. When price increase the quantity demanded for a good or service decrease and vice-versa.
Supply Curve:
The supply curve is a graphic representation of the correlation between the cost of a good or service and the quantity supplied for a given period. The price and quantity supplied of a good or service move together in the same direction. It means when price increase the quantity supplied of a good or service increase and vice-versa.
Elasticity:
Elasticity is a micro economic concept, measure the change in the quantity demanded for a good or service in relation to price changes of that good or service.
Elasticity of Demand:
The price elasticity of demand is the measure of the % change in quantity demanded to a % change in price for a specific good or service.
Price elasticity of Demand = % change in quantity demanded/ % change in price
Elasticity of Supply:
The price elasticity of supply is the measure of the % change in quantity supplied to a % change in price for a specific good or service.
Price elasticity of supply = % change in quantity supplied/ % change in price
Elasticity curves:
The elasticity curve is a graphical representation of the relationship between the % change in quantity demanded and % change in price for a given period of time.
