Final answer:
The United States Golf Association ensures that golf balls conform to regulatory standards, with over 1,800 balls from numerous companies meeting these requirements. While the balls are similar due to USGA conformance, manufacturers introduce slight variations, leading to monopolistic competition in the industry.
Step-by-step explanation:
The The United States Golf Association plays a critical role in ensuring that golf balls used in the sport meet specific criteria. Over 1,800 golf balls from more than 100 companies have been given the nod of approval to conform to USGA standards. Despite the conformity to these standards, golf ball manufacturers still introduce variances in products such as different dimple patterns and types of plastic used in the covers and cores. However, these differences are subtle as the balls need to pass certain tests, including weight and size parameters, and performance measures like lift and drag forces determined through controlled testing conditions.
Given the competitive nature of the golf ball market, and the fact that each company strives to differentiate its product while adhering to strict guidelines, this industry is characterized by monopolistic competition. A key aspect of this market structure is that while many firms compete against each other with differentiated products, the differences from the consumer's viewpoint might be minimal due to the overarching regulations enforced by the USGA.
