Resolving the measurement uncertainty paradox in ecological management [article]

Milad Memarzadeh, Carl Boettiger
2018 arXiv   pre-print
We find that simplistic optimal control approaches have repeatedly concluded that a manager should increase catch quotas when faced with greater uncertainty about the fish biomass.  ...  Using partially observed Markov decision process (POMDP) methods, we demonstrate how this paradox arises from flaws in the standard theory, which contributes to over-exploitation of fisheries and increased  ...  Essington for his insight into fisheries management, and the constructive feedback of the editor and anonymous reviewers.  ...
