Christopher Costello is a professor of natural resource economics at University of California, Santa Barbara, USA. His research focuses on decision making under uncertainty and resource use with incomplete property rights. Much of his work has focused recently on marine resources - specifically fisheries economics - where he researches catch shares and other mechanisms to simultaneously achieve profitability and sustainability.
Costello's work on fisheries economics includes work on ITQ fisheries, fisheries cooperatives, territorial user rights fisheries, marine protected areas, and optimal harvesting under uncertainty. He contributes to these areas by publishing in academic journals, engaging in policy debates, working with fishermen and non-governmental organizations, and serving as a science adviser.
