We study a spatially homogeneous model of a market where several agents or companiescompete for a wealth resource. In analogy with ecological systems, the simplest case of suchmodels shows a kind of “competitive exclusion” principle. However, the inclusion of termscorrespondingfor instance to “company e6ciency” or to (ecological) “intracompetition” showsthat, if the associated parameter overcomes certain threshold values, the meaningof “strong”and “weak” companies should be rede7ned. Also, by adequately adjustingsuch a parameter, acompany can induce the “extinction” of one or more of its competitors.
