For any number of reasons I’m interested in middlemen and brokerage.
Here are four ways that a broker might bring value to another group.
- Inform either side of interests or difficulties of the other.
- Import useful techniques, practices, tools.
- Draw analogies that the other group is blind to.
- Synthesis of techniques, practies, tools, ideas thru merging.
I very much doubt this is a usefully complete list. For example it doesn’t even include trading goods between the groups. But it’s a start.
