Possible explanations include, among others, routinization-biased technical change (technical progress substituting more easily for labor in performing routine rather than nonroutine tasks) and globalization (more specifically, offshore outsourcing by multinational firms). In this article, we develop a unified theoretical general equilibrium model and examine the implications of each competing hypotheses for labor market polarization. (JEL J21, J23, J24, F66)
