What Schooling Means to the Labor Market

in this paper we will show that the employers seeking to hire workers are never sure of their actual productivity. What they have learnt is that there is a firm relation between the workerʹs education and his productivity. Educated workers are generally more reliable, more consistent and more trainable. So employers believe that higher wages belong to those with higher productivity. The "screening hypothesis" questions the causal link, arguing that education is ʹassociated" with increased productivity, but does not "causeʹ it. The screening hypothesis argues that education gives a signal to prospective employers, and distinguishes the high productivity workers. Our purpose. in this article is to criticize the validity of the screening hypothesis, and to show why the strong form of the hypothesis does not hold.
