      Armstrong, Claire W. (Working paper; Arbeidsnotat, 2003-11)
      A transferable quota system is analysed in a two-period model with market power. So far, the management mechanisms presented in the literature to remedy market power have either not succeeded in securing efficiency in ...
    • Regulation and foreclosure 

      Sand, Jan Yngve (Working paper; Arbeidsnotat, 2003-12)
      The paper considers the optimal regulation of access charges, and the effect such regulation has on incentives to foreclose downstream rival firms. I show that when a vertically integrated firm is able to discriminate ...
    • Do incumbents have incentives to degrade interconnection quality in the internet? 

      Foros, Øystein; Sand, Jan Yngve; Kind, Hans Jarle (Working paper; Arbeidsnotat, 2003-12)
      In this paper we analyze the interconnection incentives for firms that have an installed base of customers and that also compete for new customers. We show that the small firm may be harmed in the competition for new ...
    • Regulation of a vertically differentiated duopoly 

      Sand, Jan Yngve (Working paper; Arbeidsnotat, 2003-12)
      This paper focuses on the optimal quality regulation of vertically differentiated duopolies in the presence of asymmetric information. In the model presented there are cross-effects on the information rent. Contrary to ...
    • Should environmental projects be subsidised? An empirical analysis 

      Aanesen, Margrethe (Working paper; Arbeidsnotat, 2003-12)
      Imperfect markets, asymmetric information and transboundary pollution are all characteristics that in most cases lead to inefficient “market” outcomes, and which thus are arguments for (public) intervention in the market. ...
    • Excess entry in vertically related markets 

      Sand, Jan Yngve (Working paper; Arbeidsnotat, 2003-12)
      This paper considers the problem of excess entry in vertically related markets when the regulator can regulate market structure and access charges. The endogenous access charge introduces an asymmetry between firms ...

      Borgersen, Trond-Arne; Greibrokk, Jørund; Koekebakker, Steen (Research report; Forskningsrapport, 2004)
    • Should foreign producers oppose domestic state aid? 

      Østbye, Stein (Working paper; Arbeidsnotat, 2004-03)
      Can subsidies to domestic producers, de facto, be subsidies to foreign producers? If so, state aid may distort competition to the advantage of the foreign producers. At the same time, governments often oppose subsidies ...
    • The translog neoclassical growth model 

      Østbye, Stein (Working paper; Arbeidsnotat, 2004-03)
      The macroeconomic growth equation based on the translog aggregate production function is derived and compared to the growth equation based on Cobb-Douglas both with and without human capital. The model is estimated directly ...
    • Government financial transfers to the fish harvesting, processing and aquaculture industries Norway 1990 - 2002 

      Hermansen, Øystein; Flåten, Ola (Working paper; Arbeidsnotat, 2004-03)
      This report investigates and quantifies Norwegian governmental financial transfers (GFT) to primarily the fish harvesting industry, but also the fish processing and aquaculture industries. Focus is on the period 1990 to ...
    • Marine reserves. A bio-economic model with asymmetric density dependent migration 

      Armstrong, Claire W.; Skonhoft, Anders (Working paper; Arbeidsnotat, 2004-10)
      A static bioeconomic model of a marine reserve is introduced, allowing asymmetric density dependent migration between the reserve and the fishable area. This allows for habitat or ecosystem differences within and outside ...

      Flåten, Ola; Hermansen, Øystein (Working paper; Arbeidsnotat, 2005-02)
      Landingene av torsk i Norge er sterkt sesongvarierte. Fangstene i første halvår i årene 1983- 84 utgjorde om lag 85 % av årets totalfangst. I 1986-88 var andelen sunket til om lag 70 %, mens den steg til 80 % i 1999-2000 ...
