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).

RECOGNITION LAG The time lag that it takes to identify and document the existence of an economic problem that might require government action. The recognition lag arises because it takes time to collect and analyze economic data; to verify that an actual problem exists. This "inside lag" is one of four policy lags associated with monetary and fiscal policy. The other two "inside lags" are decision lag and implementation lag, and one "outside lag" is implementation lag. All four policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy.
