A PRIORI: A presumption made before an analysis is undertaken, often based on experiences, beliefs, or deductions from seemingly self-evident propositions about how the world works. This is a Latin for assumption or axiom. A similar sounding, but opposite term is a posteriori, which is derived from observation or facts. For example, in the study of economics of crime you might assume, a priori, that people are basically "good", because that just seems to be part of human nature, and conclude, a posteriori, that people are more likely to commit crimes when the threat of capture and conviction is lower.

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.
