Final answer:
Structural unemployment occurs when there's a mismatch between the jobs available and the skills/location of the workforce. It's influenced by geographic, technological, and educational factors, and can be heightened during a recession.
Step-by-step explanation:
Unemployment that arises when there is a mismatch between the quantity of labor demanded and the quantity of labor supplied is referred to as structural unemployment. This type of unemployment is a result of various factors such as geographic location, technological changes, and educational requirements, which can all prevent workers from filling available jobs. For instance, if there are job openings in one area but the pool of unemployed labor lives elsewhere, or if workers' skills do not match the technological requirements of the job, structural unemployment occurs. Additionally, structural unemployment can be exacerbated during a recession, when there is an excess supply of labor and firms reduce hiring due to insufficient demand for their products.
