    • Equilibrium prices supported by dual price functions in markets with non-convexities 

      Bjørndal, Mette; Jörnsten, Kurt (Working Paper, Working paper, 2004-06)
      The issue of finding market clearing prices in markets with non-convexities has had a renewed interest due to the deregulation of the electricity sector. In the day-ahead electricity market, equilibrium prices are calculated ...
    • Internal pricing in supply chains 

      Fjell, Kenneth; Jörnsten, Kurt (Discussion paper, Working paper, 2001)
      A supply chain is two or more parties linked by a flow of goods, information and funds. Since this means that supply chain management concerns environments in which there are multiple decision makers, which may be different ...
    • Konkurranse i taxi markedet 

      Brunstad, Rolf Jens; Jörnsten, Kurt; Strandenes, Siri Pettersen (Rapport;2012:3, Research report, 2012-05)
      I denne rapporten oppsummerer vi resultatene fra en analyse av konkurransevirkninger av dagens konsesjons- (løyve-) praksis der fylkesmyndigheten tildeler taxisentralene innenfor ett og samme løyveområde ulike antall løyver. ...
    • Koordinering av nordiske systemoperatører i kraftmarkedet : gevinster ved bedret kapasitetsutnyttelse og mer fleksibel prisområdeinndeling 

      Bjørndal, Mette; Jörnsten, Kurt (Rapport, Research report, 2001-08)
      I rapporten vurderes mulige gevinster ved å etablere en felles systemoperatørfunksjon i det nordiske kraftmarkedet, og fokus er i første rekke på håndtering av flaskehalser i overføringsnettet. For å kunne si noe om ...
    • Lower and upper bounds for linear production 

      Bjørndal, Endre; Jörnsten, Kurt (Discussion paper, Working paper, 2002-11)
      We study a model of a production economy in which every set of agents owns a set of resources, and where they all have access to the same technology. The agents can cooperate by pooling their resources, and the total profit ...
    • Market power in a power market with transmission constraints 

      Bjørndal, Mette; Gribkovskaia, Victoria; Jörnsten, Kurt (Discussion papers;29/14, Working paper, 2014-06)
      In this paper we present a model for analysing the strategic behaviour of a generator and its short run implications on an electricity network with transmission constraints. The problem is formulated as a Stackelberg ...
    • Mixed contracts for the newsvendor problem with real options 

      Jörnsten, Kurt; Nonås, Sigrid Lise; Sandal, Leif Kristoffer; Ubøe, Jan (Discussion paper, Working paper, 2011-04)
    • Modeling Freight Markets for Coal 

      Ubøe, Jan; Andersson, Jonas; Jörnsten, Kurt; Strandenes, Siri Pettersen (Journal article; Peer reviewed, 2009)
      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 finding in the paper is that cost minimizing ...
    • 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 ...
    • Non-linear anonymous pricing in combinatorial auctions 

      Drexl, Andreas; Jörnsten, Kurt; Knof, Diether (Discussion paper, Working paper, 2005-08)
    • Norwegian petroleum taxation : estimating the value of allowing companies to pledge tax allowances from investments on the Norwegian continental shelf 

      Johansson, Fredrik (Master thesis, 2017)
      As the Norwegian continental shelf is maturing, the interest from major international companies is falling. New and smaller players that will have to take over do not have the same credit ratings as the majors, and will ...
    • Nøytralitet i vannkraftbeskatningen : virker grunnrenteskatten i Norge nøytralt på investeringsbeslutninger? 

      Hartveit, Arild; Hermansen, Miriam (Master thesis, 2017)
      For å i størst mulig grad oppnå samfunnsøkonomisk optimal ressursallokering, er nøytralitet i bedriftsbeskatningen en ønskelig egenskap. Grunnrente er en renprofitt som har sitt opphav i bruk av en begrenset naturressurs ...
    • Paradoxes in networks supporting competitive electricity markets 

      Bjørndal, Mette; Jörnsten, Kurt (Discussion paper, Working paper, 2000)
      Grid investments are normally done in electrical networks in order to achieve a well functioning integrated electricity market and/or making the network more secure, i.e. less sensitive to link failures. In general, there ...
    • Probabilistic cost efficiency and bounded rationality in the newsvendor model 

      Ubøe, Jan; Andersson, Jonas; Jörnsten, Kurt; Lillestøl, Jostein; Sandal, Leif Kristoffer (Doctoral dissertation;41/14, Working paper, 2014-12)
      In this paper we establish a link between probabilistic cost efficiency and bounded rationality in the newsvendor model. This establishes a framework where bounded rationality can be examined rigorously by statistical ...
    • Reflections about pseudo-dual prices in combinatorial auctions 

      Drexl, Andreas; Jörnsten, Kurt (Discussion paper, Working paper, 2005-04)
      Combinatorial auctions permitting bids on bundles of items have been developed to remedy the exposure problem associated with single-item auctions. Given winning bundle prices a set of item prices is called market clearing ...
    • Replication/prediction problems in the journey-to-work 

      Jörnsten, Kurt; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2002)
      In this paper we will consider gravity models for journeys-to-work. In applications of the theory it is sometimes assumed that the parameters in such models are fixed. We will provide examples to show that this is not ...
    • Revelation of preferences in trip distribution models 

      Jörnsten, Kurt; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2007)
      In this paper we will see how commuter preferences can be revealed from observations of trip distributions. We will explain how to find unique representations of preference structures leading to an observed trip distribution, ...
    • Revenue cap regulation in a deregulated electricity market : effects on a grid company 

      Bjørndal, Mette; Jörnsten, Kurt (Discussion paper, Working paper, 2001)
      In Norway, an incentive-based regulation of electricity distribution companies, based on revenue caps, was introduced in 1997. The revenues are adjusted annually, and the new revenue cap is determined on the basis of last ...
