A captive market refers to a group of consumers who have limited or no choice but to purchase a particular product or service from a specific provider. This can be due to a lack of competition, exclusive agreements, or other factors that restrict their options. As a result, the provider has a significant advantage and can often charge higher prices or offer lower quality without fear of losing customers. Captive markets can be found in industries such as utilities, healthcare, and transportation, where consumers have little control over their options and must rely on the designated provider.
