HERFINDAHL 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.

  • At the other end of the elasticity continuum is perfectly inelastic:

  • Perfectly inelastic is an elasticity alternative in which an infinitely large change in one variable (price) is needed to cause an infinitesimally small change in another variable (quantity).
  • Once again, this works for both the price elasticity of demand and the price elasticity of supply, because the negative value of the price elasticity of demand is ignored.

  • Perfectly inelastic demand and supply are represented by vertical demand and supply curves.

BANKING

An industry containing depository institutions that provide financial intermediary services and safekeeping of checkable deposits that make up an important portion of the economy's money supply. These depository institutions--including traditional commercial banks, credit unions, savings and loan associations, and mutual savings banks--pursue financial intermediation and deposit safekeeping through fractional-reserve banking. Banking is regulated by the Federal Reserve System, Federal Deposit Insurance Corporation, and the Comptroller of the Currency, among a host of other federal and state regulators.
