• Access regulation and cross-border mergers : is international coordination beneficial? 

      Lommerud, Kjell Erik; Olsen, Trond E.; Straume, Odd Rune (Working paper, Working paper, 2005-06)
      The international integration of regulated markets poses new challenges for regulatory policy. One question is the implications that the overall international regulatory regime will have for cross-border and/or domestic ...
    • Competition and physician behaviour: Does the competitive environment affect the propensity to issue sickness certificates? 

      Straume, Odd Rune; Brekke, Kurt R.; Holmås, Tor Helge; Monstad, Karin (Working paper, 2018-09)
      Competition among physicians is widespread, but compelling empirical evidence on its impact on service provision is limited, mainly due to endogeneity issues. In this paper we exploit that many GPs, in addition to own ...
    • Downstream merger with upstream market power 

      Lommerud, Kjell Erik; Straume, Odd Rune; Sørgard, Lars (Working Paper, Working paper, 2002-12)
      We examine how a downstream merger affects input prices and, in turn, the profitability of a such a merger under Cournot competition with differentiated products. Input suppliers can be interpreted as ordinary upstream ...
    • Good jobs, bad jobs and redistribution 

      Lommerud, Kjell Erik; Sandvik, Bjørn; Straume, Odd Rune (Working Paper, Working paper, 2001-08)
      We analyse the question of optimal taxation in a dual economy, when the government is concerned about the distribution of labour income. Income inequality is caused by the presence of sunk capital investments, which creates ...
    • Hospital competition in the national health service : evidence from a patient choice reform 

      Brekke, Kurt R.; Canta, Chiara; Siciliani, Luigi; Straume, Odd Rune (Arbeidsnotat;2018/10, Working paper, 2018-12)
      We study the impact of exposing hospitals in a National Health Service (NHS) to non-price competition by exploiting a patient choice reform in Norway in 2001. The reform facilitates a di§erence-in-di§erence research ...
    • How does the type of remuneration affect physician behaviour? Fixed salary versus fee-for-service 

      Brekke, Kurt R.; Holmås, Tor Helge; Monstad, Karin; Straume, Odd Rune (Working paper, 2018-09)
      We analyse the effects of fee-for-service versus fixed salary on the treatment decisions of general practitioners (GPs) and on patients’ health outcomes. Using rich Norwegian register data during 2009-2013, we find that ...
    • Industry concentration and strategic trade policy in successive oligopoly 

      Nese, Gjermund; Straume, Odd Rune (Working paper, Working paper, 2004-11)
      We study a policy game between exporting and importing countries in vertically linked industries. In a successive international Cournot oligopoly, we let the governments in the importing and exporting countries use tax ...
    • Managerial delegation and merger incentives 

      Straume, Odd Rune (Working paper, Working paper, 2003-12)
      We analyse how the internal organisation of firms affects the correspondence between private and social incentives for horizontal merger. Applying a model of endogenous merger formation in a three-firm asymmetric Cournot ...
    • Margins and market shares : pharmacy incentives for generic substitution 

      Brekke, Kurt Richard; Holmås, Tor Helge; Straume, Odd Rune (Working paper;08/13, Working paper, 2013-02)
      We study the impact of product margins on pharmacies’ incentive to promote generics instead of brand-names. First, we construct a theoretical model where pharmacies can persuade patients with a brand-name prescription to ...
    • National versus international mergers in unionised oligopoly 

      Lommerud, Kjell Erik; Straume, Odd Rune; Sørgard, Lars (Working paper, Working paper, 2003-06)
      We analyse how the presence of trade unions affects the pattern of mergers in an international oligopoly and the welfare implications thereof. We find that an international merger results in lower wages for all firms. A ...
    • Pharmaceutical patents : incentives for R&D or marketing? 

      Brekke, Kurt Richard; Straume, Odd Rune (Working paper, Working paper, 2005-11)
      We analyse how a patent-holding pharmaceutical firm may strategically use advertising of existing drugs to affect R&D investments in new (differentiated) drugs, and thereby affect the probability distribution of future ...
    • Quality and location choices under price regulation 

      Brekke, Kurt Richard; Nuscheler, Robert; Straume, Odd Rune (Working Paper, Working paper, 2002-12)
      In a model of spatial competition, we analyse the equilibrium outcomes in markets where the product price is exogenous. Using an extended version of the Hotelling model, we assume that firms choose their locations and the ...
    • Quality competition with profit constraints 

      Brekke, Kurt Richard; Siciliani, Luigi; Straume, Odd Rune (Working paper;30/12, Working paper, 2012-09)
      Firms in markets such as health care and education are often profit constrained due to regulation or their non-profit status, and they are often viewed as being altruistic towards consumers. We use a spatial competition ...
    • Strategisk regulering av gasstransport 

      Nese, Gjermund; Straume, Odd Rune (Arbeidsnotat, Working paper, 2005-02)
      EU retter gjennom sine gassmarkedsdirektiver stadig sterkere fokus på å øke konkurransen i det europeiske gassmarkedet. Et vesentlig aspekt for Norge som en stor gasseksportør er om økt konkurranse kan medføre at en ...
