World Price List

A database (or almanac) of the 'true cost' of almost every commoditised consumer good at the time and place of retail. Certain (brave) retailers might wish to sell their wares at "world price", for which customers pay the list price in the World Price List.

The WPL is based on the prevalence of supply chain management, and offers a "birds eye" "view" of the true cost of all components of the good as it makes its way along the supply chain, where the true cost has no connection with the agreed cost by the buying and selling parties at each transactional step. It takes into account energy costs*, social costs (who are you diverting from other work by having them work on your product instead), pollutant costs, health costs (is your product addictively sweetened using unnecessarily unhealthy additives, etc) and various other secondary and tertiary derived cost factors.

Obviously, there can be no definitive cost as it's a highly complex map of contributory factors many of which will remain unknown but this could act as a start, by virtue of consensus rather than accuracy. It would also demonstrate interesting effects as the price of a good will reflect where it is sold, but may (or may not) vary across different world markets.

In a way, this represents another model, other than freemium or pay-what-you-want. This is "pay what it truly costs".

* There will also need to be development of Energy Chain Management - a structure much like SCM.
