Hamilton Helmer's book 'Seven Powers' effectively disaggregates sources of market power.
Hamilton Helmer is probably the leading scholar on various sources of defensibility for businesses. He has this niche, but very well known in the niche, book called Seven Powers. It tends to disaggregate the various sources of market power in this respect. I think that is true and important, insofar as it goes.
