SCARCITY: A pervasive condition of human existence that exists because society has unlimited wants and needs, but limited resources used for their satisfaction. In other words, while we all want a bunch of stuff, we can't have everything that we want. In slightly different words, this scarcity problem means: (1) that there's never enough resources to produce everything that everyone would like produced; (2) that some people will have to do without some of the stuff that they want or need; (3) that doing one thing, producing one good, performing one activity, forces society to give up something else; and (4) that the same resources can not be used to produce two different goods at the same time. We live in a big, bad world of scarcity. This big, bad world of scarcity is what the study of economics is all about. That's why we usually subtitle scarcity: THE ECONOMIC PROBLEM.

ASYMMETRIC INFORMATION Information is not equally available to everyone. Asymmetric information results because efficient information search inevitably stops short of compete information. Some people obtain more benefits from information than others, are willing to incur higher search costs, and thus end up knowing more. Or they incur lower information search costs and have easier access to the information. In a market, sellers tend to have more information about the good than buyers. Asymmetric information gives rise to adverse selection, moral hazard, and the principal-agent problem. These problems can be lessened through signalling and screening.
