Final answer:
A shoe store manager losing their job due to an increase in online shopping represents structural unemployment. This type of unemployment is caused by a long-term change in the job market where workers' skills no longer match job requirements.
Step-by-step explanation:
The person who manages a shoe store and may be out of a job as more customers order shoes online instead of shopping in stores would be an example of structural unemployment. This type of unemployment occurs when there is a mismatch between the skills workers have and the skills needed for the available jobs, often due to technological changes, such as the growth of online shopping, which reduces the demand for in-store retail jobs.
Structural unemployment is also characterized by longer job search times as individuals may need to retrain or acquire new skills to adapt to the changing job market. In contrast to other kinds of unemployment like cyclical unemployment, which correlates to the economic cycle, or frictional unemployment, which is temporary between jobs, structural unemployment can be more persistent as it involves changes in the economy's structure itself.
