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.

TAXATION BASICS Taxes are mandatory payments from members of society to governments. The total tax revenue collected from a specific tax can be identified as the product of the tax rate times the tax base. The tax base can be specified as either a physical quantity or monetary value, giving rise to two types of tax per unit tax (quantity) and ad valorem tax (value). In some cases it is useful to specify a tax rate as an average tax rate and in other cases as a marginal tax rate.
