TANSTAAFL: A rather cumbersome and usually hard to remember acronym for the expression "There ain't no such thing as a free lunch. This is a favorite saving of many economists because it highlights, albeit in a grammatically questionable manner, the fundamental problem of scarcity. The phrase serves to emphasize that seemingly "free" lunches are not really free. While they might be free to the customer, someone must pay, that is, incur an opportunity cost of foregone production. The lunch eaten by one person cannot be eaten by 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.
