    • 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 ...

    • Do species interactions and stochasticity matter to optimal management of multispecies fisheries? 

      Poudel, Diwakar; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar; Kvamsdal, Sturla Furunes (Discussion paper;2012:1, Working paper, 2012-01)
      The multispecies fisheries management looks at a bigger picture in addressing the long-term consequences of present decisions. This implies an ecosystem management that includes a number of species and their physical, ...

    • Fisheries management under irreversible investment : does stochasticity matter? 

      Poudel, Diwakar; Sandal, Leif Kristoffer; Kvamsdal, Sturla Furunes; Steinshamn, Stein Ivar (Discussion paper;2011:20, Working paper, 2011-11)
      We present a continuous, nonlinear, stochastic and dynamic model for capital investment in the exploitation of a renewable resource. Both the resource stock and capital stock are treated as state variables. The resource ...

    • A market-based approach to manage endangered species interactions 

      Kvamsdal, Sturla Furunes; Stohs, Stephen M. (Discussion paper, Working paper, 2010-09)
      An economic activity interacts with an endangered species. The activity can be divided into mutually exclusive strata with different levels of inter- action. Observing the activity in order to monitor interactions is ...

    • Optimal maintenance scheduling of local public purpose buildings 

      Hopland, Arnt O.; Kvamsdal, Sturla Furunes (Discussion paper;36/14, Working paper, 2014-11)
      We formulate the maintenance scheduling decision as a dynamic optimization problem, subject to an accelerating decay. This approach offers a formal, yet intuitive, weighting of the trade-offs involved when deciding a ...

    • Technological change in renewable resource industries: an alternative 

      Kvamsdal, Sturla Furunes (Discussion paper;2012:14, Working paper, 2012-12)
      I set forth a generalized stochastic time trend approach, based upon the Kalman filter, as an alternative to the general index approach to measure technological change. Technology is treated as a latent variable in a ...

    • 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 ...
