Final answer:
A profit-maximizing monopoly can operate in the elastic portion of its demand curve, where a decrease in price leads to a larger increase in quantity sold and higher total revenue. If a baseball club were maximizing revenue, it would aim for a unitary elasticity of demand.
Step-by-step explanation:
A major-league baseball club may operate as a profit-maximizing monopoly. One way to test if a firm is a profit-maximizing monopoly is to check if it operates in the elastic portion of its demand curve. This is a relevant test because in the elastic portion, a decrease in price leads to a larger increase in quantity sold, resulting in higher total revenue. If a baseball club were maximizing revenue, it would aim for a unitary elasticity of demand. At this point, an equal percentage change in quantity and price would result in the same total revenue.
