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).

PERFECT COMPETITION, LONG-RUN PRODUCTION ANALYSIS

In the long run, a perfectly competitive firm adjusts plant size, or the quantity of capital, to maximize long-run profit. In addition, the entry and exit of firms into and out of a perfectly competitive market guarantees that each perfectly competitive firm earns nothing more or less than a normal profit. As a perfectly competitive industry reacts to changes in demand, it traces out positive, negative, or horizontal long-run supply curve due to increasing, decreasing, or constant cost.
