Skilled and Unskilled Labor
This chapter examines how skilled and unskilled labor vary across countries by taking into account the wage rate for skilled labor and the wage rate for unskilled labor, based on the assumption that labor markets approximate conditions of perfect competition. The equation to be used implies that the relative wage of a skilled worker is decreasing with the relative supply of skills. However, for a given supply of skills the relative wage also depends on the relative efficiency with which skills are used. The chapter first estimates the skill bias, the relative supply of skills, and the skill premium before deriving a calibrated value for the elasticity of substitution. It then presents the key empirical results for the skill bias in technology across countries and goes on to discuss alternative skill thresholds. It also considers the implications of differences in school quality and the implications of capital–skill complementarity.
