Final answer:
A glass blower replaced by a machine exemplifies technological unemployment, which is a form of structural unemployment where advancements make certain skills obsolete.
Step-by-step explanation:
The skilled glass blower who becomes unemployed due to a new machine that performs her job faster is an example of technological unemployment, which is a subtype of structural unemployment. This occurs when there is a societal mismatch between the available jobs and the skills of the workforce.
Technological advancements can render certain skills obsolete, leading to this specific type of structural unemployment. Since factory workers' skills are often specific to their industry, they may face difficulty finding new employment without retraining or may have to accept lower-paying jobs.
The unemployment of the skilled glass blower in this scenario is an example of structural unemployment. Structural unemployment occurs when certain skills are no longer in demand in the labor market. In this case, the new machine that performs the glass blowing job faster has made the glass blower's skills obsolete.
