MARKET FAILURES: Conditions in which a market does not efficiently allocate resources to achieve the greatest possible consumer satisfaction. The four main market failures are--(1) public good, (2) market control, (3) externality, and (4) imperfect information. In each case, a market acting without any government imposed direction, does not direct an efficient amount of our resources into the production, distribution, or consumption of the good.

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.
