• Solving oligopolistic equilibrium problems with convex optimization 

      Egging-Bratseth, Ruud; Baltensperger, Tobias; Tomasgard, Asgeir (Peer reviewed; Journal article, 2020)
      The approach of choice to analyze markets with oligopolistic competition has traditionally been complementarity modeling. In this paper we show that the majority of partial equilibrium models under imperfect competition ...
    • Stochastic modeling of imperfect markets 

      Baltensperger, Tobias; Egging, Ruud (Chapter, 2017)
      Stochastic optimization approaches ignore that the decisions of different actors in markets typically do not lead to a system-wide optimal solution. Suppliers in markets with entrance barriers or other aspects that hinder ...
