ON THE MANAGEMENT OF INTERCONNECTEDWILDLIFE POPULATIONS

摘要

Economic interdependency of wildlife or fish stocks is usually attributed to ecological interdependency, such as predator–prey and competitive relationships, or to density-dependent migration of species betweendifferent areas. This paper provides another channel for economic interdependency of wildlife where density-independent migration and market priceinteraction affect the management strategies among different landowners.Management is studied under three market conditions for selling huntinglicenses: price taking behavior, monopoly market, and duopoly market. Harvesting of the Scandinavian moose is used as an example. The paper providesseveral results on how economic interdependency works through the migration pattern. When a duopoly market is introduced, hunting license priceinteraction among the landowners plays an additional role in determiningthe optimal harvesting strategy.
