Final answer:
Hector is considered as part of frictional unemployment, which is a normal economic condition referring to individuals transitioning between jobs or seeking better employment fits.
Step-by-step explanation:
The situation described where Hector voluntarily left his job to search for a new job in the field he is trained in is commonly associated with the labor economics concept of unemployment. Specifically, Hector would be considered as being part of frictional unemployment. Frictional unemployment occurs when individuals are temporarily unemployed while transitioning between jobs or when they are searching for a job that better matches their skills and interests, as in Hector's case with his accounting degree. Although Hector is unemployed, frictional unemployment is considered to be a normal part of a healthy economy because it reflects the time taken to find the best employment match.
