      Steinshamn, Stein Ivar (Working Paper, Working paper, 2005-12)
      The aim of this review article is to give an overview over some of the literature on so-called market based management in fisheries. Market-based management is, however, a term that has been used with different meanings ...
    • More is less : the tax effects of ignoring flow externalities 

      Sandal, Leif Kristoffer; Steinshamn, Stein Ivar; Grafton, R. Quentin (Discussion paper, Working paper, 2000-11)
      Using a model of nonlinear decay of the stock pollutant, and starting from the same initial conditions, the paper shows that a tax that only corrects for stock externalities can, at the steady state, be higher than a tax ...
    • A new approach of fitting biomass dynamics models to real data based on a linear total allowable catch (TAC) rule : an optimal control approach 

      Ussif, Al-Amin M.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 2000-05)
      A non-traditional approach of fitting dynamic resource biomass models to data is developed in this paper. The adjoint technique is an optimal control or a variational method for parameter identification. It provides a novel ...
