• Livestock and Carnivores: Economic and Ecological Interactions 

      Olaussen, Jon Olaf; Johannesen, Anne Borge; Skonhoft, Anders (Journal article; Peer reviewed, 2019)
      Carnivores-livestock interactions cause human-wildlife conflicts worldwide. These interactions are present under a wide range of ecological and economic circumstances. This paper studies the relationship between predation ...
    • On the Economics of an Atlantic Salmon Recreational Fishery 

      Olaussen, Jon Olaf (Doktoravhandlinger ved NTNU, 1503-8181; 2007:34, Doctoral thesis, 2007)
      This thesis includes four essays on the management of wild Atlantic salmon (Salmo salar). The main focus is on the management of the recreational fishery; thus, the focus is on salmon in the rivers, where anglers buy fishing ...
    • On the economics of biological invasion: An application to recreational fishing 

      Olaussen, Jon Olaf (Working Paper Series, 1503-299X; 2005:12, Research report, 2005)
      The paper demonstrates four general mechanisms that may affect economically valuable species when exposed to biological invasion. We distinguish between an ecological level effect and an ecological growth effect. In addition ...

      Wild Atlantic salmon are traditionally harvested from both the sea and spawning rivers during spawning runs. From an economic point of view, the return from sport fishing in rivers is several times higher than marine ‘for ...
    • The bioeconomics of a wild Atlantic salmon (Salmo salar) recreational fishery 

      Olaussen, Jon Olaf; Skonhoft, Anders (Working Paper Series, 1503-299X; 2005:14, Research report; Peer reviewed, 2005)
      A biomass model of a wild salmon (Salmo salar) river recreational fishery is formulated, and the ways in which economic and biological conditions influence harvesting, stock size, profitability, and the benefit of the ...
    • The economics of a stage-structured wildlife population model 

      Olaussen, Jon Olaf; Skonhoft, Anders (Working Paper Series, 1503-299X; 2005:17, Research report, 2005)
      A simple three-stage model of the Scandinavian moose (Alces alces) (young, adult female and adult male) is formulated. Fecundity is density dependent while mortality is density independent. Two different harvesting regimes ...
