| | Abstract |
| | Because commercially valuable species are in interdependent relationships with many species |
| | sharing their habitat, understanding ecological relationships is an important part of designing |
| | renewable resource policies. Equally important is to understand how these policies impact human |
| | activity, and how this activity affects species in the ecosystem. This paper offers a new integrated |
| | ecological/economic model that can track both ecological relationships and human activities. Based |
| | on individual behavior directing aggregate outcomes, the approach allows for multiple species in |
| | complex food webs. The ecosystem model is combined with a general equilibrium model of an |
| | economy, providing a tight integration of economic and ecological models. The combined model is |
| | applied to Alaska and a commercially important eight species marine ecosystem that contains |
| | harvested fish and endangered Steller sea lions. Results illustrate that when humans intentionally |
| | interact with ecosystems there are often unintended consequences. Termed ecosystem |
| | externalities, the model demonstrates how these externalities can be measured. |
