2002 World Congress of Environmental and Resource Economists

This paper concerns the management of the Swedish wolf (Canis lupus), which is a species with a high dispersal capacity. The goal is to choose a harvesting strategy, such that the discounted stream of net benefits from the populations in different geographical regions is maximized. The spatial dimension is involved through emigration and immigration. The solution to the management problem is shown to be a modification of the classical rule of renewable resource exploitation, caused by migration between regions. Empirically, this problem is solved by dividing Sweden into 13 geographical regions, and accounting for existence values, harvesting benefits, and predation costs of the wolf population in each region. The highest densities of wolves were found in regions with low marginal costs, due to a very high abundance of moose equivalents per hunter. The lowest population densities were found in regions with low carrying capacity for the wolf or high cost of depredation on reindeer.

The goal is to choose a harvesting strategy, such that the discounted stream of net benefits from the populations in different geographical regions is maximized. The spatial dimension is involved through emigration and immigration. The solution to the management problem is shown to be a modification of the classical rule of renewable resource exploitation, caused by migration between regions. Empirically, this problem is solved by dividing Sweden into 13 geographical regions, and accounting for existence values, harvesting benefits, and predation costs of the wolf population in each region. The highest densities of wolves were found in regions with low marginal costs, due to a very high abundance of moose equivalents per hunter. The lowest population densities were found in regions with low carrying capacity for the wolf or high cost of depredation on reindeer.
