While the mathematical difficulty of multiple species may quickly become overwhelming, sometimes making the single...

This paper explores the effect of an individual’s knowledge of biodiversity on the nature of his or her preferences for its preservation. Previous research suggests that individuals have a limited understanding of the concept of biodiversity and that some may be unwilling to trade-off changes...

A large amount of New Zealand’s critical remaining habitat for endemic species is located on private land. In its biodiversity strategy, the government proposes several types of economic incentives to encourage voluntary conservation by private landowners. This research investigates the...

Soil erosion research in New Zealand has focused on the on-site costs of soil loss in the form of production loss and storm damage. Subsidization and implementation of soil conservation measures have primarily been justified through maintenance or improvement of farm productivity levels. The...

Exploitation frequently reduces the mean age of a fish population, particularly where a lack of property rights stimulates producers to ignore the user cost of harvest. The authors demonstrate that harvesting a young fish bears a significant efficiency cost when the multiple benefits accruing to...
