for evidence on the effects of offshoring. More recently, services offshoring and its consequences have gained more attention in the literature; see, for example, Winkler (2010) and Eppinger (2014). 4 A recent example analysing the link between offshoring and outsourcing potentials is the working paper by Hogrefe (2013). He analyses the effect of offshoring on relative labour demand measured as the share of routine tasks in occupations in German manufacturing industries. The dependent variable can also be used as a proxy for how easily jobs can be offshored in the future. 5 A recent article by Blinder and Krueger (2013) summarises the attempts and methods to answer this question for the United States. Additionally, it can be argued that the public debate and the scientific reality need to be further aligned (Smith, 2006). 6 With regard to the outsourcing margin, things like contractibility and relationship specificity come into play. The most straightforward idea is that of the transaction cost approach (Whinston, 2003), which argues that the more relationship-specific the task, the lower its outsourcing potential. The property rights theory by Antr as (2003) and Antr as and Helpman (2004) further introduces headquarter intensity into this margin.
