Developing even a simple economic model for a small module in a DApp seem to be very hard, as it requires a lot of brainstorming to predict/pre-define all possible behaviours of the user, especially if you are an application developer but not an economist :)
Problem with DApps is that these pre-defined rules should be accurate in the first place, otherwise your Dapp may end up in falling down after release, as you are not going to get 2nd chance to fix those.
So the question is how to know whether the economic model, that we are thinking of is correct?
One way to learn all those related topics to economics and human behaviour like Game theory, Mechanism design etc. but then to fully understand them, might take you years and you might fall in the rabbit hole. Other can be learned from existing designed models, like how facebook and twitter doing.
We can do a lot of brainstorming and come with a simple model, and then we can simulate it to any Agent based programming modeling tools (like, NetLogo) to see it produces expected behaviour or not.
