Game theory describes situations of conflict, limited resources, and competition. Given a certain situation and a limited amount of resources and time, what decisions are competitors likely to make, and which should they make? One important note is that traditional game theory may describe humans as more rational than they really are. Game theory is theory, after all. - Shane Parrish Business - Economics: "Scarcity refers to the limited availability of a commodity, which may be in demand in the market. The concept of scarcity also includes an individual capacity to buy all or some of the commodities as per the available resources with that individual" - Wikipedia (James Clear)
