Which of the following statements regarding frictional unemployment is correct? |ForumIAS

[A] It is the time period between jobs when a worker is searching for, or transitioning from one job to another.

[B] Frictional unemployment exists because both jobs and workers are homogeneous.

[C] Frictional unemployment is rarely present in an economy.

[D] Both (a) and (c)

Answer: A

Notes:

Explanation:

Frictional unemployment exists because both jobs and workers are heterogeneous, and a mismatch can result between the characteristics of supply and demand. Such a mismatch can be related to skills, payment, work-time, location, seasonal industries, attitude, taste, and a multitude of other factors.
Frictional unemployment is always present in an economy, so the level of involuntary unemployment is properly the unemployment rate minus the rate of frictional unemployment, which means that increases or decreases in unemployment are normally under-represented in the simple statistics.
