      Sometimes you're wondering about something and then someone just goes and writes the paper answering your question. In other news, Enrico Moretti finds that concentrated agglomerations like Silicon Valley lead to higher total patent output: http://papers.nber.org/tmp/41233-w26270.pdf …pic.twitter.com/Ss3NM2BhXs

      I read it and the effect sizes seem too small to me!

      How much bigger would you expect? They make rough intuitive sense IMO; we see these agglomerations and should expect some effect, but we don't see "escape velocity" growth takeoffs so effects shouldn't be too big.

      Parenting would decline only 11% in the absence of any agglomeration effects? I would guess 2-3X that and maybe more.

      Not entirely sure I'm right about this, but I don't think he sets agglomeration to 0, just redistributes talent equally. So there'd still be latent agglomeration ~everywhere (at the background average level) in his model. Maybe part of the story?

      Yeah, depends how you define it, I guess. But I would consider uniform distribution across cities the baseline!
