Market mechanism - a designed (rather than spontaneously emerging) market.
Market mechanisms are often engineered with policy goals in mind. Among the most well-known (and controversial) of these is the Kyoto Protocol's Clean Development Mechanism for issuing and trading GHG emissions permits.
Project Persephone studies market mechanisms for how they might substitute for (and even improve upon) bureaucratic governance. Market mechanisms might be designed for both exovivaria and the organization itself. The mechanisms might be tested in virtual exovivaria and terrestrial prototypes of exovivaria. Some mechanisms might apply to communities in equatorial alpine regions that have been selected as Project Persephone aid beneficiaries, where the local culture is open to such experiments.
Here are some market mechanisms under consideration:
- Prediction markets for planning. These might include markets for
- Georgist taxation for equitable funding of most non-market governance. A tax only on the value of exovivarium interior spaces minus the value of their improvements helps foster an unhindered market for improvements. The value of property minus its improvements could be determined by a free market for internal space combined with competition in a market for (mandated) insurance on all improvements. Exovivaria could, after all, be damaged or lost through orbital debris impacts, internal conflagrations3 and other catastrophic events. Different surfaces and volumes within exovivaria might have varying market values, even prior to improvements. 4
- Emissions trading markets for ecosystem protection and management. Exovivaria will require keeping ecosystems alive with a very high ratio of "technosphere" mass to natural resource mass compared to the Earth's surface. User preferences for biomass will also tend toward a higher-than-natural fauna-to-flora ratio, since animals are more interesting to watch and interact with than plants. These two factors will greatly increase the need to balance emissions with consumption. In a habitat rotated for artificial gravity, even the movement of animals and user telebots, and the flow of water, could be classified as "emissions"; such movement, if ill-timed, could interfere with the effort of keeping the exovivarium's solar collector pointed toward the sun; however, if well-timed, they could be used to maintain the exovivarium's orientation.5
- Resource exchanges for physical design of exovivaria.6 These could certainly be applied to virtual exovivaria and terrestrial prototypes; they might also apply to various picosatellite proof-of-concept experiments. Given the complexities and constraints of exovivaria, resource exchanges might even prove valuable to users in their property improvements within exovivaria.
- Coupon socialism7 to democratize incentives for project success. Project Persephone will adopt localities in equatorial alpine regions selected as candidate projectile space launch sites; it may emphasize employing local populations to build terrestrial prototypes of exovivaria and as telebot operators. Assigning potentially dividend-paying coupons to citizens in such areas enfranchises them in the success of the Project, including the success of enterprises affiliated with it -- especially enterprises that might employ them.
- Bancor-style international trading units.8 The purpose would be to immunize funding of aid projects against exchange-rate fluctuations, and to help to ensure that trade among Project members flows toward selected equatorial alpine regions. When the Project as a whole is suffering coordination failures or internal political deadlock, a liquidity channel to its aid-beneficiary regions would at least help keep benefits flowing; individual donors could still buy goods and services from individual aid beneficiaries.
- Forward markets for prevention of asset bubbles.9 If the high costs of exovivarium launch can be met with promises to deliver on-orbit "real estate" to sufficiently charitable donors, there would still be the risk that those donors would fall prey to "irrational exuberance" in trading that not-yet-real estate among themselves. Such a market failure could prematurely signal that exovivarium launch had become economically feasible. It would be better for all concerned to get the timing right.10

2 More research into "thin markets" might be required to make prediction markets workable in the Project Persephone context, since design of exovivaria will often require rare specialist expertise.

3 Not exactly unknown, in spacecraft. The Apollo 1 capsule interior was destroyed by a fire made more intense by a pure oxygen atmosphere, taking the lives of three astronauts. There was a fire aboard the Mir space station, possibly 14 minutes long, caused by the malfunction of a chemical oxygen generator. ⇑
