How did they come to be called "pivot tables"? Was it a standard use of "pivot" at the time? 

Like people would say "oh ya just pivot that table" or something? 

 Does anyone have a reference for a nice lay summary of the framework Weitzman uses in Prices vs Quantities? Like a blog post or something about that paper? 

I'm particularly interested in something that explains the whole "costs of being wrong" and "why we might be wrong" for folks who haven't read the paper

@fbe1ee42 do you have a reference? I know climate shock talks about fat tails and dismal theorem logic, I haven't found as much on the PvQ logic
