Sheepskin effect
The sheepskin effect is a phenomenon in applied economics observing that people possessing a completed academic degree earn a greater income than people who have an equivalent amount of studying without possessing an academic degree.[1][2] There are many applied economics papers which investigate the signaling effect of possession of such an academic degree.
For example, if Student A is one credit short of a Bachelor's degree, while Student B has earned their Bachelor's degree, then the two students have essentially the same amount of education. However, according to the sheepskin effect, Student B will earn a greater income than Student A.
Newer evidence suggests that the sheepskin effect exists but could be contingent on the type of degree – Associate's or Bachelor's – earned.[3]
