At least the one I respect more (Samuelson) has a decent quote: Disagree. Reason: 'This would be a great idea if the market for service provision was competitive, but is less obvious with our current market.' On the other hand, it's sad that smart people that should know better (Chetty, Altonji) answered like that. One interesting observation is the IO/Finance divide. IO experts (Liran Einav) are in favor of NN, while Finance folks (Darrell Duffie) are against. Probably because the latter almost always think about efficiency, while if you work in IO you have to be aware of the market structure (and natural monopolies, etc)
