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.

ECONOMY:

The system of production, distribution, and consumption of goods and services that a society uses to address the problem of scarcity.
An economy can be simple, such as that illustrated by the hilarious antics of the hapless passengers and crew of the U.S.S. Minnow on the highly popular economic documentary, Gilligan's Island. Or it can be exceedingly complex, such as the modern U.S. economy with millions of workers, thousands of corporations, and trillions of dollars worth of capital that are used to produce trillions of dollars worth of goods and services for millions of people.

Production and Consumption

The essential task of an economy is to transform resources into useful goods and services (the act of production), then distribute or allocate these products to useful ends (the act of consumption). Production involves the transformation of labor, capital, land, and entrepreneurship into more valuable goods and services. Consumption is then the use of these goods and services to satisfy the wants and needs of people.

Markets and Government

Virtually all economies accomplish this production-consumption task through a combination of decisions made through voluntary market exchanges and involuntary government laws, rules, and regulations. Capitalism is the term used for those economies relying predominately on markets, while communism and socialism are the names for economies coming down more heavily on the side of government decision making.
