Competence Among Companies: Coexistence and Extinction

Marcelo N. Kuperman and Horacio S. Wio
Physica A 316, 592-600 (2002)

We have studied a spatially homogeneous model of a market where several companies compete for a wealth resource. In analogy with ecological systems we find that the simplest case of such models shows a kind of "competitive exclusion" principle. However, the inclusion of terms corresponding to ecological intracompetition shows that, if such parameters overcome certain threshold values, the meaning of ``strong" and ``weak" companies should be redefined. Also, by adequately adjusting such a parameter, a company can induce the "extinction" of one or more of its competitors.
