Milk has an inelastic demand, and beef has an elastic demand. Suppose that a mysterious increase in bovine infertility decreases both the population of dairy cows and the population of beef cattle by 50 percent.
The change in equilibrium quantity will be

a. greater in the milk market than in the beef market.
b. greater in the beef market than in the milk market.
c. the same in the milk and beef markets.
d. Any of the above could be correct.

b.greater in the beef market than in the milk market.

Explanation:

Elasticity of demand measures the responsiveness of quantity demanded to changes in price.

Demand is elastic if quantity demanded is more sensitive to changes in price. A small change in price leads to a greater change in quantity demanded.

Demand is inelastic if when price changes, there is little or no change in quantity demanded.

If there's bovine fever which decreases the population of beef cattle by 50 percent, supply would fall and price would rise. As a result of the rise in price, quantity demanded of beef would fall more than the quantity demanded of milk because beef has an elastic demand while milk has an inelastic demand.
