In addition to Mokyr, several other speakers also considered measurement problems affecting productivity assessments, e.g. through the underestimation of GDP (the numerator of aggregate productivity measures). Jones (2017) and Varian (2017) referred to software or services provided for free or at very low prices by ICT firms or not-for-profit institutions (e.g., Facebook, Google or Wikipedia).
The existing EU treaties do not provide for such a transfer of responsibilities, which could also have farreaching financial implications for the member states. Treaty change would therefore be needed to provide a rock-solid legal basis for these measures, too. A conceivable interim solution would be to form a network of national resolution authorities, as proposed by the German government.
