Hoagland, P. and D. Jin, Science and economics in the management of an invasive species, BioScience 56(11):931-935, 2006

Estimates of the economic impacts of non-native, nuisance (?invasive?) species must rely upon both a sound ecological understanding and the proper application of economic methods. We focus on one example using the invasive European green crab (Carcinus maenas), where the economic impact estimate has been used to help justify recent public policy. We show that the economic impact estimate for the green crab is based upon data taken from the wrong geographic location, the predictions of ecological effects appear to rest on loose footing, and economic methods have been misapplied in constructing the estimate. Our purpose is to call attention to the need for the more careful application of science and economics in managing this pressing environmental issue. PDF:
