    • Properties of range-based volatility estimators 

      Molnàr, Peter (Journal article; Peer reviewed, 2012)
      Volatility is not directly observable and must be estimated. Estimator based on daily close data is imprecise. Range-based volatility estimators provide significantly more precision, but still remain noisy volatility ...
    • 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 ...

      EU's objective of attaining 20% reductions in greenhouse gas emissions by 2020 is analysed with a general equilibrium model detailing electricity generation technologies and capital vintaging. Consistent with theory and ...
    • Bok og nettside som integrert læreverk 

      Bøhren, Øyvind; Gjærum, Per Ivar (Journal article; Peer reviewed, 2012)
      Denne artikkelen bruker et konkret pedagogisk prosjekt i finans til å vise hvordan ønsket om undervisning med relevans og mangfold kan avleire seg i et læreverk. Vår nøkkel er å utvikle bok og nettside i tidsmessig parallell ...
    • Strategic insider trading equilibrium: A filter theory approach 

      Aase, Knut K.; Bjuland, Terje; Øksendal, Bernt (Journal article; Peer reviewed, 2012)
      The continuous-time version of Kyle’s (Econometrica 53(6):1315–1336, 1985 ) model of asset pricing with asymmetric information is studied, and generalized in various directions, i.e., by allowing time-varying liquidity ...
    • Some aspects of random utility, extreme value theory and multinomial logit models 

      Andersson, Jonas; Ubøe, Jan (Journal article; Peer reviewed, 2012)
      In this paper we give a survey on some basic ideas related to random utility, extreme value theory and multinomial logit models. These ideas are well known within the eld of spatial economics, but do not appear to be ...
    • The Hybrid Model of Agent’s Power in Social Networks 

      Belik, Ivan (Journal article; Peer reviewed, 2012-10)
      The basic idea of the research is to investigate and formalize functional dependency between structural and social measures in social networks. Since interpersonal relations are composed of multiple factors with different ...
    • Give and take in dictator games 

      Cappelen, Alexander Wright; Nielsen, Ulrik H.; Sørensen, Erik Øiolf; Tungodden, Bertil; Tyran, Jean-Robert (Journal article; Peer reviewed, 2013)
      It has been shown that participants in the dictator game are less willing to give money to the other participant when their choice set also includes the option to take money. We examine whether this effect is due to the ...
    • An Educational Game in Collaborative Logistics 

      D'Amours, Sophie; Rönnqvist, Mikael (Journal article; Peer reviewed, 2013)
      We describe an educational game in collaborative logistics. The game is based on an award-winning application in cost allocation in transportation. The purpose of the game is to acquire an understanding of negotiation, ...
    • Stochastic Stackelberg equilibria with applications to time-dependent newsvendor models 

      Øksendal, Bernt; Sandal, Leif Kristoffer; Ubøe, Jan (Journal article; Peer reviewed, 2013)
      In this paper, we prove a maximum principle for general stochastic differential Stackelberg games, and apply the theory to continuous time newsvendor problems. In the newsvendor problem, a manufacturer sells goods to a ...
    • A maximum entropy approach to the newsvendor problem with partial information 

      Andersson, Jonas; Jörnsten, Kurt; Nonås, Sigrid Lise; Sandal, Leif Kristoffer; Ubøe, Jan (Journal article; Peer reviewed, 2013)
      In this paper, we consider the newsvendor model under partial information, i.e., where the demand distribution D is partly unknown. We focus on the classical case where the retailer only knows the expectation and variance ...
    • Hva vet vi om dem som skjuler inntekt og formue i skatteparadis? 

      Andersson, Jonas; Lillestøl, Jostein; Støve, Bård; Schjelderup, Guttorm (Journal article; Peer reviewed, 2013)
      I denne artikkelen presenteres resultater fra et prosjekt utført for SNF (Samfunns- og Næringslivsforskning) på oppdrag av Skattedirektoratet (SKD). Hensikten med prosjektet var å finne kjennetegn ved personlige skattytere ...
    • Dead Battery? Wind Power, the Spot Market, and Hydropower Interaction in the Nordic Electricity Market 

      Mauritzen, Johannes (Journal article; Peer reviewed, 2013)
      It is well established within both the economics and power system engineering literature that hydropower can act as a complement to large amounts of intermittent energy. In particular hydropower can act as a “battery” where ...
    • Modellering av usikkerhet i numeriske likevektsmodeller med stokastisk scenariometode : 

      Brekke, Kjell Arne; Golombek, Rolf; Kaut, Michal; Kittelsen, Sverre A.C.; Wallace, Stein (Peer reviewed; Journal article, 2013)
    • Diffusion of pharmaceuticals: cross-country evidence of anti-TNF drugs 

      Brekke, Kurt; Dalen, Dag Morten; Holmås, Tor Helge (Journal article; Peer reviewed, 2014)
      This article studies the diffusion of biopharmaceuticals across European countries, focusing on anti-TNF drugs, which are used to treat autoimmune diseases (e.g., rheumatism, psoriasis). We use detailed sales information ...
    • An experimental study of prosocial motivation among criminals 

      Cappelen, Alexander Wright; Sørensen, Erik Øiolf; Tungodden, Bertil; Birkeland, Sigbjørn (Journal article; Peer reviewed, 2014)
      The fact that criminal behavior typically has negative consequences for others provides a compelling reason to think that criminals lack prosocial motivation. This paper reports the results from two dictator game experiments ...
    • Harvesting in a Fishery with Stochastic Growth and a Mean-Reverting Price 

      Kvamsdal, Sturla F; Poudel, Diwakar; Sandal, Leif Kristoffer (Journal article; Peer reviewed, 2014)
      We analyze a continuous, nonlinear bioeconomic model to demonstrate how stochasticity in the growth of fish stocks affects the optimal exploitation policy when prices are stochastic, mean-reverting and possibly harvest ...
    • Scrapping a wind turbine: Policy changes, scrapping incentives and why wind turbines in good locations get scrapped first 

      Mauritzen, Johannes (Journal article; Peer reviewed, 2014)
      The most common reason for scrapping a wind turbine in Denmark is to make room for a newer turbine. The decision to scrap a wind turbine is then highly dependent on an opportunity cost that comes from the interaction of ...

    • One size fits all? Facility management in Norwegian local governments 

      Hopland, Arnt Ove (Journal article; Peer reviewed, 2014)
      Up to the mid-1990s almost all Norwegian local governments had a decentralized structure on their facility management. Over the following 15 years a swift centralization followed, and in 2010 roughly 85% of the ...
