• Analyzing risk of stock collapse in a fishery under stochastic profit maximization 

      Poudel, Diwakar; Sandal, Leif Kristoffer; Kvamsdal, Sturla Furunes (Discussion paper;2012:4, Working paper, 2012-04)
      In commercial fisheries, stock collapse is an intrinsic problem caused by overexploitation or due to pure stochasticity. To analyze the risk of stock collapse, we apply a relatively simple Monte Carlo approach which can ...
    • The ensemble Kalman filter in bioeconomics 

      Kvamsdal, Sturla Furunes; Sandal, Leif Kristoffer (Discussion paper;2012:5, Working paper, 2012-05)
      We demonstrate the power of the Ensemble Kalman Filter in specifying ecosystem models ideal for bioeconomic analysis. Bioeconomic analysis requires models to be relatively simple, but models must still capture the nature ...
