Postscript: Intrinsically, cities aren't cauldrons of innovation. Cities draw people from a diverse set of places. Cities also provide more inter-firm labor mobility opportunities. Most migration covers a short distance. You go where you know. Thus the observation of a positive correlation between urban density and innovation/productivity. Right connection, wrong explanation.
