I'm not aware if there's dynamic economy
Kiiiind of? As in, you can see the framework of how it could work, and to a certain extent, specific actions by one player at-for example-the Grim Hex Orbital station can affect trade for another player, but it's a level of detail I wont bore you with by typing out a gigantic wall of text.
But again, it's not fully fleshed out, and lacks a few elements, but it's not nothing, and what it is, is enough to have spawned a trade war among players, which we are having loads of fun with.
