    • Searching for optimal integer solutions to set partitioning problems using column generation 

      Bredström, David; Jörnsten, Kurt; Rönnqvist, Mikael (Discussion paper;20/07, Working paper, 2007-08)
      We describe a new approach to produce integer feasible columns to a set partitioning problem directly in solving the linear programming (LP) relaxation using column generation. Traditionally, column generation is aimed ...

    • Shapley-Based Stackelberg Leadership Formation in Networks 

      Belik, Ivan; Jörnsten, Kurt (Discussion paper;16/15, Working paper, 2015-04-10)
      In the given research we study a leadership formation of the most influential nodes in networks. Specifically, we analyze the competition between a leader and a follower based on the Stackelberg leadership model. Applying ...

    • Strategic Pricing of Commodities 

      Jörnsten, Kurt; Ubøe, Jan (Journal article; Peer reviewed, 2009)
      We consider a setting where a large number of agents are trading commodity bundles. Assuming that agents of the same type have a certain utility attached to each transaction, we construct a statistical equilibrium which ...

    • Strategic pricing of commodities 

      Jörnsten, Kurt; Ubøe, Jan (Discussion paper, Working paper, 2006)
      In this paper we will consider a setting where a large number of agents are trading commodity bundles. Assuming that agents of the same type have a certain utility attached to each transaction, we construct a statistical ...

    • The Analysis of Leadership Formation in Networks Based on Shapley Value 

      Belik, Ivan; Jörnsten, Kurt (Discussion paper;02/15, Working paper, 2015-01-09)
      In the given research we analyse how an agent can move towards leadership in a socio-economic network. For the node’s (i.e., agent’s) importance measure we use the Shapley value (SV) concept from the area of cooperative ...

    • The coauthorship network analysis of the BI Norwegian business school 

      Belik, Ivan; Jörnsten, Kurt (Discussion papers;31/14, Working paper, 2014-07)
      We construct the coauthorship network based on the scientific collaboration between the faculty members at the Norwegian Business School (BI) and based on their international academic publication experience. The network ...

    • The coauthorship network analysis of the Norwegian school of economics 

      Belik, Ivan; Jörnsten, Kurt (Discussion papers;20/14, Working paper, 2014-05)
      We construct the coauthorship network based on the scientific collaboration between the faculty members at the Norwegian School of Economics (NHH) and based on their international academic publication experience. The ...

    • The comparative analysis of the NHH and BI networks 

      Belik, Ivan; Jörnsten, Kurt (Discussion paper;34/14, Working paper, 2014-09)
      Based on the co-authorship networks of the Norwegian School of Economics (NHH) and the BI Norwegian Business School we present a comparative analysis in terms of structures, collaborations and publications. The networks’ ...

    • The Method of Leader’s Overthrow in Networks 

      Belik, Ivan; Jörnsten, Kurt (Discussion paper;1/16, Working paper, 2016-01-21)
      Methods for leader’s detection and overthrow in networks are useful tools for decision-making in many real-life cases, such as criminal networks with hidden patterns or money laundering networks. In the given research, we ...

    • Transfer of risk in the newsvendor model with discrete demand 

      Jörnsten, Kurt; Nonås, Sigrid Lise; Sandal, Leif Kristoffer; Ubøe, Jan (Journal article; Peer reviewed, 2012)
      In this paper we consider the transfer of risk in a newsvendor model with discrete demand. We view the newsvendor model as a leader/follower problem where the manufacturer (leader) decides the wholesale price and the ...

    • Viewing the deregulated electricity market as a bilevel programming problem 

      Bjørndal, Mette; Jörnsten, Kurt (Discussion paper, Working paper, 2000)
      In this paper we present a bilevel programming formulation of a deregulated electricity market. By looking at a deregulated electricity market in this format we achieve two things, the relation between a deregulated ...

    • Zonal pricing in a deregulated electricity market 

      Bjørndal, Mette; Jörnsten, Kurt (Discussion paper, Working paper, 1999)
      In the deregulated Norwegian electricity market a zonal transmission pricing system is used to cope with network capacity problems. In this paper we will illustrate some of the problems that the zonal pricing system, as ...
