There is some precedent for the "Centrally Planned Regional Economy" idea. Lazarus was quite keen on iron production during the PRL years and had an unusually high position in the World Census for something metal related - arms manufacturing or mining or something like that.
I had had this silly idea that there could be a market economy for the GCRs that they could participate in. And their would be a "basket of goods" that related to inflation, price parity and trade.
Obviously I never really fleshed the idea out further....
