202402251449 The tragedy of the commons

#new

In a commons system there is a resource that is shared (e.g. a shared pasture for cattle grazing). For these systems to be tragedy, the shared resource must be erodible (i.e. the further it's degraded, the harder it is to regenerate the resource) and the users of that resource must be incentivized to use the resource even in the face of the erosion (e.g. immigrants may hurry or increase in numbers if they hear immigration laws are going to become tougher).¹

The way out of this trap is to educate people on the value of the resource and the necessity of conservation. If that doesn't work, privatization (splitting up and assigning portions) will create the feedback signal (cost) to individuals for them to feel the effects of everyone's actions. We could also regulate everyone's access to the resource in order to conserve it (e.g., limited entry to a popular national park).
