Final answer:
The primary goal of unemployment insurance is to reduce workers' uncertainty about their income by providing temporary financial help to those who have lost their jobs. It's a program funded by employers to support job seekers. Although it might reduce frictional unemployment as a side effect, that is not its main purpose.
Step-by-step explanation:
The main goal of the unemployment-insurance system is to reduce a. Workers' uncertainty about their income. Unemployment insurance is a program into which employers pay. These funds are used to provide temporary financial assistance to workers who have lost their jobs through no fault of their own and are actively seeking work.
It should be noted that while unemployment insurance can help with reducing frictional unemployment by giving people more time to find the right job match, that is more of a positive side effect rather than the main goal. Frictional unemployment levels are influenced by factors such as the ease with which workers can learn about jobs and their willingness to move for employment which may be affected by history and culture.
