WELFARE ECONOMICS: A branch of economics that studies efficiency and the overall well-being of society based on alternative allocations of scarce resources. Welfare economics extends the microeconomic analysis of indifference curves to society as a whole. It is concerned with broad efficiency questions and criteria (Pareto efficiency and Kaldor-Hicks efficiency) as well as more specific efficiency issues (market failures, externalities, public goods).

ADVERSE SELECTION An inefficient, bad, or adverse outcome of a market exchange that results because buyers and/or sellers make decisions based on asymmetric information. This commonly results in a market that exchanges a lesser quality good, what is termed the market for lemons. Two related problems resulting from asymmetric information are moral hazard and the principal-agent problem. Two methods of lessoning the problem of adverse selection are signalling and screening.
