    • 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 ...

    • Continuous harvesting costs in sole-owner fisheries with increasing marginal returns 

      Sandal, Leif Kristoffer; Steinshamn, Stein Ivar; Maroto, Jose M.; Moran, Manuel (Working paper, Working paper, 2009-06)
      We develop a bioeconomic model to analyze a sole-owner fishery with fixed costs as well as a continuous cost function for the generalized Cobb-Douglas production function with increasing marginal returns to effort level. ...
