Map of the global distribution of economic and physical water scarcity as of 2006. Scarcity is the fundamental economic problem of having seemingly unlimited human wants in a world of limited resources. It states that society has insufficient productive resources to fulfill all human wants and needs.
How does the context of scarcity shape our choices and our behaviors? They show that scarcity is not just a physical limitation. Scarcity affects our thinking and feeling. Scarcity orients the mind automatically and powerfully toward unfulfilled needs. For example, food grabs the focus of the hungry. For the lonely person, scarcity may come in poverty of social isolation and a lack of companionship. On the positive side, scarcity prioritizes our choices and it can make us more effective. Scarcity creates a powerful goal dealing with pressing needs and ignoring other goals. For example, the time pressure of a deadline focuses our attention on using what we have most effectively.
