Do Trade Bans Protect Endangered Species? Evidence from the World’s First Possession Ban
Guest Speaker: John Lynham, Economics Department, University of Hawaii
Venue: ESRI, Whitaker Square, Sir John Rogerson’s Quay, Dublin 2.
There have been growing calls to legalize the trade of endangered species in order to better protect them. In theory, prohibition of trade drives up prices and could be accelerating the path to extinction but this claim has never been evaluated empirically. Evaluation is hampered by the difficulty of collecting data on an illegal activity and finding appropriate counterfactuals for the 183 countries that currently support prohibition. In 2010, the state of Hawaii adopted the world's most stringent ban on the trade of shark fins: physical possession of fins became a crime that could lead to imprisonment. Prior to the ban, fishers in Hawaii were allowed to sell the fins of sharks caught "accidentally". Using a unique panel dataset that follows the primary group of fishers and an unaffected counterfactual group before and after the ban went into effect, the speaker will present research which quantifies the effect of the ban on Hawaii's shark population.
