Ed provides Bill de Blasio with
some free advice for how to lead a great city. The de Blasio Era will offer a great natural experiment to test for cross-elasticities. Manhattan is a superstar city.

Or will they stay because there are no close substitutes for Manhattan? NYC in the 1970s wasn't cool. The next mayor should read up about
local Laffer curves and urban taxation..
