Answer:
1) The correct answer is letter "B": unemployed workers accept the first job offer that they receive.
2) The correct answer is letter "A": Dave searches for a new job after voluntarily moving to San Diego.
Step-by-step explanation:
1) Frictional unemployment is one of what economists call natural unemployment triggered by factors other than an underperforming economy. Frictional unemployment is caused by temporary changes. This involves conditions such as the entry of new employees into the workforce, people moving to another city and searching for a job or people leaving to search for a better job.
Therefore, an unemployed accepting the first offer received does not reflect frictional unemployment.
2) Under the same concept, Dave's case would reflect what frictional unemployment causes. By moving to another city at will, he starts looking for a new job. One of the causes of frictional unemployment is the relocation to another city and pursuit of a career in the new city.
