New Size Measurements in Population Ecology

In organizational ecology, we find the analysis of the impact exerted by competition between populations on vital ratios to be relatively under-developed. This paper intends to address this issue by developing new competition measurements whose common denominator is to give importance to organizational size. The application of these measurements in the case of competition between organizational forms in a population and their impact on mortality rates, demonstrates the usefulness of modelling competition on them. More specifically, results show how competition levels between firms in a population can be more adequately estimated when rival population mass is used (that is, the aggregate size of the organizations of which it is made up).
