This came to me while I was seeking to come up with an economic system for a near-future science fiction background, where trauma and technology has reset the economy. I think it is orginal but full of flaws, which is good for SF (see Asimov's three laws of robotics). Note that there are far fewer people
The idea is that each person and corportation divides the percentage of their economic interest between what they want to support. Therefore a corporation, for example, divides it's interests between employees, suppliers, overheads and raw materials.
On a regular basis all these percentage breakdowns are analysised and each person and corporation has a "Worth Rank" (WR) dependent on how suppported that person is and the WR of each supporter. This is akin to the calculations of Google Rank, which is based on links (or at least's that the short version).
If you sufficiently support a consumer product corporation it supplies you with it's products, offers support and continues development. People with a higher WR need to supply less, to get the same level of service, than someone with a lower WR.
Support to an artist would result in art (with mechanisms on how to order and acquire), support to a news agency would result in news and support to a temple would consist of columns ...
All this information would be public and the services of WR optimisation advisers (offering the equivalent of SEO) would be on offer too.
The idea is such a system elimates the accumilation of money because all you get is support, which can be withdrawn at any time. Obviously money would creep back in, if desireable enough items could be controlled.
A drawback would be that people would constantly seek to curry support from others but there would also be an economic incentive to produce popular things and services that people actually want.
A parallel political system would have to exist in order to answer "Who Watches the Watchmen" (and fill the "Google" role in SEO management), however the hope would be that such a system keeps people too busy to voice too much dissent.
