Job Competition Theory (Thurow, Lester, 1968) suggests, that choosing candidate for the job, the employer gives preference to those, whom he less likely to spend money on; in this case, the employer chooses the most experienced and educated candidate, no matter what skill level is actually required for the job, and pays the salary, corresponding to the complexity of the work, but not taking into account the real level of qualification of hired employee; as a result in the labor market can be created a disparity between the level of employment of high and low-skilled workers, as any employer, even for low-level jobs will select the most qualified candidates, and skilled workers in a situation of unemployment will accept jobs actually require less than their real qualifications.
