A couple of folks had interesting counterpoints to the superstar effect. Neil Strickland gave me permission to post the following email he sent:
I wonder if you’ve read, or if I’ve referred to, the Santa Fe Institute’s highly cited 2007 paper in PNAS (Proceedings of the National Academy of Sciences) called “Growth, Innovation, Scaling, and the pace of life in cities.” Its work was in “deriving growth equations which quantify the dramatic difference between growth fueled by innovation versus that driven by economies of scale. This difference suggests that, as population grows, major innovation cycles must be generated at a continually accelerating rate to sustain growth and avoid stagnation or collapse.”
