Equilibrium unemployment with outsourcing under labour market imperfections

"We study both the various consequences and the incentives of outsourcing. We argue that the wage elasticity of labour demand is increasing as a function of the share of outsourcing, which is importantly a result consistent with existing empirical research. Furthermore, we show that a production mode with a higher proportion of outsourcing activity reduces the negotiated wage in the high-wage country with an imperfectly competitive labour market so that outsourcing reduces equilibrium unemployment. Finally, we characterize the optimal production mode and show that stronger labour market imperfections lead to a production mode with a higher share of outsourcing"--Forschungsinstitut zur Zukunft der Arbeit web site.
