      In this paper we study the evolution of the regulation of the Norwegian aquaculture industry, in particular how European integration has affected the development of the regulatory regime. We analyse whether the transformation ...
    • On how size and composition of customer bases affect equilibrium in a duopoly with switching costs 

      Gabrielsen, Tommy Staahl; Vagstad, Steinar (Working Paper, Working paper, 2001-10)
      Switching costs may facilitate monopoly pricing in a market with price competition between two suppliers of a homogenous good, provided the switchi8ng cost is above some critical level. It is also well known that asymmetric ...
    • On modelling the market for natural gas 

      Mathiesen, Lars (Working Paper, Working paper, 2001-12)
      Several features may separately or in combination influence conduct and performance of an industry, e.g. the numbers of sellers or buyers, the degree of economies of scale in production and distribution, the temporal and ...
    • On revenue and welfare dominance of ad valorem taxes in two-sided markets 

      Kind, Hans Jarle; Koethenbuerger, Marko; Schjelderup, Guttorm (Working paper, Working paper, 2008-04)

    • On the choice of royalty rule to cover fixed costs in input joint ventures 

      Fjell, Kenneth; Foros, Øystein; Kind, Hans Jarle (Working paper;16/13, Working paper, 2013-07)
      In a model where two competing downstream firms establish an input joint venture (JV), we analyze how different royalty rules for covering fixed costs affect channel profits. Under running royalties (regardless of whether ...
    • On the costs and benefits of vertical integration 

      Gabrielsen, Tommy Staahl (Working paper, Working paper, 2003-06)
      We consider a setting where two upstream firms may vertically integrate or contract with a single downstream distributor. Under vertical integration the integrated firm may offer to share the downstream capacity with its ...
    • On the dynamics of commercial fishing and parameter identification 

      Ussif, Al-Amin M.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Working Paper, Working paper; Working paper, 2002-03)
      This paper has two main objectives. The first is to develop a dynamic model of commercial fisheries different from most existing models that assume optimizing behavior. The industry is assumed to have a well-defined index ...
    • On the efficiency gains of emissions trading when climate deals are non-cooperative 

      Godal, Odd; Holtsmark, Bjart (Working paper, Working paper, 2011-07)

      Röller, Lars-Hendrik; Steen, Frode (Working Paper, Working paper, 2005)
      Using the institutional set-up of the Norwegian cement industry, in particular its sharing rule, we are able to identify the workings of a cartel in some detail. Given data on prices, production, and exports, we are able ...
    • Operational expressions for the marginal cost of indirect taxation when merit arguments matter 

      Schroyen, Fred (Working paper, Working paper, 2009-02)
