OPPORTUNITY COST: The highest valued alternative foregone in the pursuit of an activity. This is a hallmark of anything dealing with economics--and life for that matter--because any action that you take prevents you from doing something else. The ultimate source of opportunity cost is the pervasive problem of scarcity (unlimited wants and needs, but limited resources). Whenever limited resources are used to satisfy one want or need, there are an unlimited number of other wants and needs that remain unsatisfied. Herein lies the essence of opportunity cost. Doing one thing prevents doing another.

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.
