similar patterns of behavior. Ex) tragedy of commons & limits to growth
movement if things in and out of stocks
speed at which things flow in and out of stocks
time something spends in any particular stock
close the route between stock, rate and flow which creates dynamic behavior of that stock.
Types of feedback loops
(R)einforcing: accelerate the size of the stock; positive
(B)alancing: stabilize systems and drive that system to a certain “stable” state or target; negative
limits to growth
something inside or outside the system limits the growth of the condition. Will be S-shaped if the limiting condition is something constant such as available habitat, reached carrying capacity. could be 'overshoot +crash' b/c disease/resources/war etc.
