Tragedy of the Commons Archetype

Gene Bellinger
A Tragedy of the Commons situation exists whenever two or more activities, each, which in order to produce results, rely on a shared limited resource. Results for these activities continue to develop as long as their use of the limited resource doesn't exceed the resource limit. Once this limit is reached the results produced by each activity are limited to the level at which the resource is replenished.

Gene Bellinger
A Growth and Underinvestment with a Drifting Standard structure is simply an elaborated Growth and Underinvestment structure where the growth inhibitor induces a decline of the standard over time. The real nasty thing about this structure is that the growth inhibitor influence sets up a Reinforcing Loop which even further promotes a drifting of the standard over time.
