Outsourcing versus Integration at Home or Abroad

Using data on a sample of Italian manufacturing companies, this paper analyzes the location (at home or abroad) and the mode of organization (outsourcing versus integration) of intermediate inputs production. We find evidence of a productivity ordering (largely consistent with the assumptions in Antr�s and Helpman 2004) where foreign integration is chosen by the most productive and domestic outsourcing by the least productive firms; those with medium-high productivity choose domestic integration, those with medium-low productivity foreign outsourcing. We also find that the preference for integration over outsourcing is positively related to some indicators of headquarter intensity, notably capital intensity, as predicted by Antr�s (2003) and Antr�s and Helpman (2004).
