A template to be used when a stock metrically can't grow beyond a certain point---e.g. a 0-10 psychometric scale. 
The technique used to address the problem is based on Zeno's paradox, where Achilles is unable to reach a finish line because he must first cross half the distance, then half the remaining distance, ad infinitum. Likewise, this system reduces the growth rate proportionately to how close the stock is to the defined ceiling.
Parameters include the base growth rate (the rate at which the stock increases before the system's balancing loop activates), the ceiling, the initial value of the stock, and a "tolerance point." This is the point at which the system decides to intervene to prevent the stock from passing the ceiling, and begins to reduce the growth rate. Raising the tolerance of the system gives the base growth rate more dominance over the behavior graph while sharpening the negative curve at the top of the S-curve.
A note concerning simulation---only Runge-Kutta will calculate the appropriate behavior. Using Euler will result in oscillations around the ceiling.

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.

An escalation structure results from two or more competing entities with the competition taking them to somewhere none of them want to be.

The Limits to Growth Archetype demonstrates the manner in which initial growth may be slowed over time by a limiting factor.

Archetype Limits To Growth Systems KeLE Perspectives

A Growth and Underinvestment structure is simply an elaborated Limits to Growth structure where the growth inhibitor is part of another Balancing Loop with an external standard and some delay. The real nasty thing about this structure is that the two Balancing Loops form a single Reinforcing Loop which inhibits growth.

Success to the successful archetype represents two reinforcing structures which may be in a delicate balance though as soon as one gains a small advantage the resource allocation favors the more successful and the result is then rapidly skewed in the direction of the more successful.

Once this limit is reached the results produced by each activity are limited to the level at which the resource is replenished.
