One of the devs is from CCP (EVE Online) and the biggest thing that EVE is praised for is it's economy. I wouldn't be surprised if Pathfinder replicated the system because it fits a sandbox MMO so well.
If you do some research you'll find that many of your suggestions are already implemented in EVE's system so I wouldn't stress too much about it.
Things like:
Region based micro-economies
NPC brokers
Logistics and trade routes
Buy/sell Order
