Solomon Hsiang and Nitin Sekar published an op-ed in the Guardian, in answer to the question: "Would a legal ivory trade save elephants or speed up the massacre?"
The op-ed discusses the recent research findings from the Lab that legal ivory sales in 2008 increased poaching, rather than decreased poaching as the policy intended.
These findings were cited in editorials by the New York Times and the Guardian calling for stronger action and regulation (or total bans) of legal ivory trade.
Negotiations for creating a permanent legal global ivory market were halted at the recent meeting of the Convention on the International Trade in Endangered Species, in part due to these research findings.
