HHI: The common abbreviation for the Herfindahl-Hirshman index (or the Herfindahl index), which is 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.

Topic: Inefficiency <=PAGE BACK | PAGE NEXT=>

Inefficient use of resources can result from:
  • The fourth rule of competition-with less competition buyers or sellers control the price. The quantity is too little and the demand price is greater than the supply price.
  • The seventh rule of complexity-costs or benefits external to the market (externalities) cause differences between the value of goods produced and goods not produced, even though market demand and supply prices are equal.
  • The fifth rule of imperfection-markets are not perfect.
    • Scarcity implies the lack of competition.
    • Complexity implies externalities.
Efficiency is a goal, not a perpetual state of the world.
