@michaeljon - I am glad you enjoyed this as I put a lot of work into thinking through this idea. Treatments of this idea are in Bessen’s book, Sutton’s book, (Sunk Costs and market structure), and Economics of Strategy, 7th edition.
To your question, yes, that is what I am saying. Companies have discretion and control over what they spend versus some technology, which is exogenous and affects all the same.
In the case of brands, its an intangible investment. But, to use another example, Amazon has made significant investments into its delivery / logistics infrastructure to achieve quality (i.e. quick shipping). So, this is not intangible, but rather tangible but at their discretion.
Sutton noted advertising and R&D are endogenous sources of costs, but I think the Amazon example is another way to think about the idea not in those categories.
I am going to great pains to differentiate exogenous from endogenous, with the latter being in managements control and at their discretion.
No book for me! This is a concept according to the CFT system Cedric speaks about that goes [case] - [concept] - [case]. So, I will write a case and link back to this.
For instance, I read Emperors of Chocolate, and certain inventions came to be like the enrober, which is similar to bessemer process allowing for scale. Later, Hershey and Mars really started to advertise and get the distribution to squeeze others out. So, I am kind of thinking this was an entry barrier market that became a Sutton one! Basically, in any book I read where I see major inflections in industry structure, I will probably link to this conept.
This idea is not fully fleshed out yet though. Sorry for the long post.
