Price Elasticity of Demand and Supply
There is a relationship between demand and price. How much demand
for a commodity is affected by a change in price is called elasticity of de-
mand. If a small change of price results in a large change in demand, the
demand is called elastic, if the demand changes only a little, it is called in-
elastic. The price elasticity of demand coefficient is negative as demand usu-
ally falls with a rise in price.
The price elasticity of supply shows the percentage change in the quantity
supplied resulting from a one-percent change in price.
As an increase in the quantity supplied is normally a result of a rise in
price, the coefficient is usually positive. We have a "0" (zero) elasticity when
a price change results in no quantity supplied change. This is called a perfect-
ly inelastic supply. Provided the elasticities vary between zero and one, the
supply is called inelastic. With coefficients greater than one, the supply is
called elastic. The percentage change in quantity is larger than the corre-
sponding percentage change in price.
Agricultural supply is mostly inelastic because of the high proportion of
such inputs as land, buildings, and machinery. The elasticities of agricultur-
al commodities (potatoes, wheat, fruits, eggs, milk) vary greatly. Because of
increasing specialization of production, of farm animal products, in partic-
ular, elasticities for such commodities as pigs or broilers have decreased in
recent years.
