This project presents an empirical modeling approach for predicting the economic and ecological consequences of alternative halibut PSC management policies. There are three modeling efforts represented: area-time-species abundance, Rational Expectations Random Utility Maximization (RERUM) Estimator, and RERUM Location Choice Data for the BSAI Groundfish Non-pollock Trawl Fleet. Fisheries, Environmental, Economic and Management data for model of area-time-species abundance. Bering Sea, Aleutian Islands and Golf of Alaska Areas. Daily data for specially defined areas. 2008-2018. Because of Research Workshop upload limits, output data is divided into two parts. AbundanceOutput_confidential_1.csv and AbundanceOutput_confidential_2.csv. These data should be combined rowise to use (append 2 on 1). Model input data and shapefiles are also provided. Modeling code for the Rational Expectations Random Utility Maximization (RERUM) estimator estimates the parameters of a spatiotemporal fishing behavior model that incorporates the dynamic and general equilibrium elements of fisheries with tradable short-term rights of annual catch entitlements. The RERUM estimator code is written in the MATLAB programming language. The RERUM location-choice model for the BSAI groundfish non-pollock trawl (i.e., the Amendment 80) fleet dataset is comprised of publicly available third-party data (e.g., species-specific TAC allocations), spatiotemporal estimates of CPUE (from our abundance model), and confidential data (e.g., location choices and harvests from the North Pacific observer program). Confidential data have been censored from the dataset.
