Goldman Sach economists say that technological improvements have increased productivity but this is not reflected in the statistics. Statistical measurement is an issue they say. Economists at JP Morgan Chase say the problem is that many of the technological improvements have not increased productivity in manufacturing, and there is a misallocation of resources to apps such as Uber and new products that do not increase productivity in the economy. Their view is that this is not a measurement issue, the drop in productivity makes sense and is very real. Compared to earlier shifts in technology this one has provided little in the way of serious improvement.
