Species preservation and biodiversity value: a real options approach

Article Abstract:

They examine optimal conservation decision given that a biodiversity loss is irreversible and that future use values are uncertain. While species substitutability has been shown to reduce the value of diversity, they show that the flexibility is associated with substitutability. The irreversibility that characterizes options creates convexity in value, which explains why increased volatility means increased values; instead volatility and expected return are substitutes in a standard portfolio model.

Habitat conservation, wildlife extraction and agricultural expansion

Article Abstract:

A model of open access wildlife exploitation, habitat conservation and agricultural expansion, which is consistent with rural communities in areas such as sub-Saharan Africa, is put forth. The different patterns of conservation and agricultural expansion, and wildlife stocks are discussed.

Uncertainty and species recovery program design

Article Abstract:

The economic aspects of reintroducing large, wide-ranging mammalian carnivores, like wolves and grizzly bears, to their native habitats are discussed. The likelihood of the species is affected by the uncertainty over liability for damages.
