Answer:
Structurally.
Step-by-step explanation:
Unemployment rate refers to the percentage of the total labor force in an economy, who are unemployed but seeking to be gainfully employed. The unemployment rate is divided into various types, these include;
1. Cyclical unemployment rate (CU).
2. Frictional unemployment rate (FU).
3. Structural unemployment rate (SU).
Structural unemployment can be defined as an involuntary unemployment that arises as a result of the incompatibility between a worker's skills set and requisite skills an employer seeks from the workers or due to technological changes.
In this scenario, Arthur chooses not to accept a minimum wage job offer but rather chose to continue looking for a better job.
Hence, Arthur is structurally unemployed.
