Equity. Equity means fairness or evenness, and achieving it is considered to be an economic objective. Despite the general recognition of the desirability of fairness, it is often regarded as too normative a concept given that it is difficult to define and measure. However, for most economists, equity relates to how fairly income and opportunity are distributed between different groups in society.
Economic efficiency. In economics, the term economic efficiency refers to the use of resources so as to maximize the production of goods and services.
