OLIGOPOLY, CONCENTRATION: Oligopoly is a market structure that contains a small number of relatively large firms, meaning oligopoly markets tend to be concentrated. A small number of large firms account for a majority of total output. Concentration unto itself is not necessarily bad, but it often leads to inefficient behavior, such as collusion and nonprice competition. Concentration is measured in three ways--market share, concentration ratio, Herfindahl index.

TAX EQUITY

The notion that taxes are imposed on society in a fair and equitable way. The two standards of fairness and equity used to evaluate taxes are the benefit principle -- those who benefit from government pay the taxes, and the ability-to-pay principle -- those with the most income pay the taxes. The ability-to-pay principle gives rise to two additional notions of fairness -- horizontal equity (those with equal incomes pay equal taxes) and vertical equity (those with different incomes pay different taxes).
