Organizational Ecology - Density Dependence

Density Dependence

Organizational ecology also predicts that the rates of founding and mortality are dependent on the number of organizations (density) in the market. The two central mechanisms here are legitimation (the recognition or taken-for-grantedness of that group of organizations) and competition. Legitimation generally increases (at a decreasing rate) with the number of organizations, but so does competition (at an increasing rate). The result is that legitimation processes will prevail at low numbers of organizations, while competition at high numbers.

The founding rate will therefore first increase with the number of organizations (due to an increase in legitimation) but will decrease at high numbers of organizations (due to competition). The reverse holds for mortality rates. Thus, the relationship of density to founding rates has an inverted U shape and the relationship of density to mortality rates follows a U-shaped pattern.

Famous quotes containing the word dependence:

    This immediate dependence of language upon nature, this conversion of an outward phenomenon into a type of somewhat in human life, never loses its power to affect us. It is this which gives that piquancy to the conversation of a strong-natured farmer or backwoodsman, which all men relish.
    Ralph Waldo Emerson (1803–1882)
