With Lemducim excavating other District's minerals this turn, but offering for Mr Feb's bid to become City Manager to buy votes with stone mechanisms, an interesting economic issue has presented itself: Who owns a finished good? Is it the District who provides the raw material without explicitly charging for it, or is it the District that produces the item out of that raw material?
I'm leaning toward this: Unless a District specifically sells the raw material out of their District, that it's considered part of that District's "raw wealth". If another District volunteers to work that raw material into a finished good without attempting to transfer ownership of the raw material to their District first, then the finished good is still owned by the original owners who have just gotten work done as a philanthropic gesture from another District. However, in the case of unwanted wealth, such as too many stones or logs, a District may offer to allow other Districts to come and take away the unwanted material "for free", and as such will lose ownership of that raw material from the moment it's carted off.
This is particularly interesting when looking at the Lemducim/Olive Grove combined turn: Whatever stone goods the Lemducim District produces during the next year, they'll still owe the Founder's District 50% the value of. If, however, the mineral rights of the minerals from the Olive Grove District remain with them, then all the furniture and soap that the Lemducim District promised to trade for those goods would be in trade for items they already own. If, however, Lemducim gains ownership of those finished goods through the act of converting them from raw materials, the Olive Grove District is paying both raw materials AND finished goods for the Lemducim finished goods. (With Lemducim supplying only the labor and time needed to convert the raw resources into finished goods. Is this a fair trade?)
This choice will have interesting ramifications on who holds the wealth in the City: If a metalworker can gain ownership of a bar of metal simply by turning it into an item, or a jeweler gain ownership of a raw gem simply by cutting the jewel or gain ownership of a finished good simply by encrusting it with jewels, then the economic structure of The City will certainly become a different system. Only when an item is no longer able to be improved would it become "stable wealth" (ie: not able to have its ownership unilaterally shifted).
(Incidentally, the position of City Manager is appointed by the Mayor or the Expedition Leader if no Mayor is yet elected. The Expedition Leader, Miss Light Earthenfrost, has no problem with Mr Feb stepping down as Chief Medical Dwarf and replacing Miss Light Dreamstorches, so long as Mr Light Justicepaper replaces Mr Feb as CMD. However, she will listen to the advice of the City Council in case they have other ideas.)
