Final answer:
Occupational licenses are used to establish quality and competency in the labor market. One occupation that does not require a license for competency is stress analyst. However, licenses can create barriers to entry and limit competition.
Step-by-step explanation:
Occupational licenses are used to establish quality in the labor market and show that a worker has completed certain education or passed a specific test. Some professionals, such as doctors, teachers, nurses, engineers, accountants, and lawyers, are required to hold a license.
Additionally, many states require licenses for occupations like barber, embalmer, dietitian, massage therapist, hearing aid dealer, counselor, insurance agent, and real estate broker.
However, one thing not included as necessary to licensee competency is a stress analyst. This occupation requires a state license only in Louisiana.
It's important to note that while occupational licenses ensure competency and protect consumers, they can also create barriers to entry and restrict competition in certain industries.
