The Convention on International Trade in Endangered Species (CITES) trade b
an on ivory remains controversial despite a recent decision to permit some
exports by three African countries. In this paper, we examine arguments opp
osing and supporting the trade ban, concluding that the case for maintainin
g the ban is strong. We demonstrate that permitting some trade is not a pan
acea because of potential strategic behavior, and that resuming restricted
trade gives an impetus to illegal poaching by enhancing the possibility to
launder illegal ivory. Analysis of the pre-ban data, and using the approach
dynamics for a steady state, indicates that, when trade in ivory is allowe
d, poaching could drive the African elephant to extinction. The trade ban a
rrests this path of decline. Thus, care should be taken before lifting the
trade ban. (C) 1999 Elsevier Science B.V. All rights reserved.
