Content: Or does the government control these kinds of choices? How can a group of workers, each specializing in certain tasks, produce so much more than the same number of workers who try to produce the entire good or service by themselves? Adam Smith offered three reasons. List them and briefly describe the rationale behind each. First, specialization in a particular small job allows workers to focus on the types of production where they have an advantage. People have different skills, talents, and interests, so they will be better at some jobs than others. The particular advantages workers may be based on educational choices, which are in turn shaped by interests and talents: for example, only those with medical degrees qualify to become doctors. Second, workers who specialize in certain tasks often learn to produce more quickly and with higher quality. This pattern holds true for many workers, including assembly line laborers who build cars, stylists who cut hair, and doctors who perform heart surgery.
