The type of unemployment that occurs when an individual cannot find a job as a result of obsolete skills is known as Structural unemployment.
Structural unemployment happens when there is a mismatch between the skills that job seekers possess and the skills required for available jobs in the market. In this case, individuals may no longer be qualified for the jobs that are available due to changes in technology, market conditions, or shifts in the economy.
For example, let's say there is a rapid advancement in technology that makes certain job skills obsolete. Workers who had those skills may struggle to find employment because companies are now looking for individuals with more up-to-date skills.
This type of unemployment is different from cyclical unemployment, which is caused by fluctuations in the business cycle, or seasonal unemployment, which occurs due to seasonal variations in demand for certain jobs. Frictional unemployment, on the other hand, refers to the temporary unemployment that occurs when individuals are transitioning between jobs or entering the workforce for the first time.
To sum up, structural unemployment is the type of unemployment that arises when an individual cannot find a job because their skills are no longer in demand.
