HERFINDAHL-HIRSHMAN INDEX: A measure of concentration of the production in an industry that's calculated as the sum of the squares of market shares for each firm. This is an alternative method of summarizing the degree to which an industry is oligopolistic and the relative concentration of market power held by the largest firms in the industry. The Herfindahl index gives a better indication of the relative market control of the largest firms than can be found with the four-firm and eight-firm concentration ratios.

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).
