Wage Dispersion and Overqualification as Entailed by Reder Competition

b'The expansion of higher education in the Western countries has been accompanied by a marked widening of wage differentials and increasing overqualification. While the increase in wage differentials has been attributed to skill-biased technological change that made advanced skills scarce, this explanation does not fit well with the observed increase in overqualification which suggests that advanced skills are in excess supply.\\n\\nBy "Reder-competition" I refer to the simultaneous adjustment of wage offers and hiring standards in response to changing labor market condition. I present a simple model of Reder competition that reproduces the simultaneous increase in wage differentials and overqualification in response to an increase in education.'
