Endangered species are in predator/prey, mutualistic, competitive, or other types of relationships with many other species that share their habitat. Understanding these ecological relationships is an important part of designing endangered species policies. We employ a general equilibrium model...

The theory for a general equilibrium ecosystem model that can include large number of interacting species is presented. Features include: 1) individual plants and animals are assumed to behave as if they are maximizing their net energy intake, 2) short and long-run equilibriums are obtained, 3)...
