    • Cost efficiency analysis based on the DEA and StoNED models : case of Norwegian electricity distribution companies 

      Cheng, Xiaomei; Bjørndal, Endre; Bjørndal, Mette (Discussion papers;28/14, Working paper, 2014-06)
      Our paper applies data envelopment analysis (DEA) and stochastic non-parametric envelopment of data (StoNED) to measure cost efficiency of electricity distribution companies. The data cover 123 Norwegian electricity ...

    • Hospital competition with soft budgets 

      Brekke, Kurt Richard; Siciliani, Luigi; Straume, Odd Rune (Discussion paper;6/2012, Working paper, 2012-03)
      We study the incentives for hospitals to provide quality and expend cost-reducing effort when their budgets are soft, i.e., the payer may cover deficits or confiscate surpluses. The basic set up is a Hotelling model with ...

    • Hospital mergers with regulated prices 

      Brekke, Kurt Richard; Siciliani, Luigi; Straume, Odd Rune (Discussion paper;21/2014, Working paper, 2014-05)
      We study the effects of a hospital merger using a spatial competition framework with semialtruistic hospitals that invest in quality and expend cost-containment effort facing regulated prices. We find that the merging ...

    • Modeling freight markets for coal 

      Andersson, Jonas; Jörnsten, Kurt; Strandenes, Siri Pettersen; Ubøe, Jan (Discussion paper, Working paper, 2008-12)
      In this paper we study bulk shipping of coal between the central regions in the world. We compare the performance of cost-minimizing models with a gravity model approach. The main nding in the paper is that cost minimizing ...

    • Modeling heterogeneity in trip-distributions with partial information 

      Jörnsten, Kurt; Kleppe, Gisle; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2007)
      In this paper we propose a modified gravity model that takes into account that a population generally consists of heterogeneous groups, and we suggest a new statistical test for heterogeneity. We apply our new model to two ...
