An analysis of data from the International Federation of Robotics (IFR), currently the most widely used data on the economic effects of robotization, has found that robotization has significantly lower productivity effects than previously assumed and may cause falling wages. Authors Karim Bekhtiar, Benjamin Bittschi and Richard Sellner (EconPol Europe, IHS Vienna) claim that using the data can be misleading if information on sectors that are either unaffected by or only marginally exposed to robotization is combined with those which are heavily affected, such as manufacturing.The study also rejects previous research findings that the technology causes skill-biased technological change and instead finds the opposite to be true.
