    • 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 ...
    • Searching for the DGP when forecasting : is it always meaningful for small samples? 

      Andersson, Jonas (Journal article; Peer reviewed, 2006)
      In this paper the problem of choosing a univariate forecasting model for small samples is investigated. It is shown that, a model with few parameters, frequently, is better than a model which coincides with the data ...
    • Sequential investment in renewable energy technologies under policy uncertainty 

      Sendstad, Lars Hegnes; Chronopoulos, Michail (Journal article; Peer reviewed, 2019)
    • Simulating physical basis risks in the Capesize freight market 

      Ådland, Roar Os; Jia, Haiying (Peer reviewed; Journal article, 2017)
      The purpose of this paper is to evaluate the characteristics of the time-varying differential between the Baltic global trip-charter average and simulated earnings from a fleet of Capesize vessels. We interpret the standard ...
    • 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 ...
    • Stackelberg equilibria in continuous newsvendor models with uncertain demand and delayed information 

      Øksendal, Bernt; Sandal, Leif Kristoffer; Ubøe, Jan (Journal article; Peer reviewed, 2014)
      We consider explicit formulae for equilibrium prices in a continuous-time vertical contracting model. A manufacturer sells goods to a retailer, and the objective of both parties is to maximize expected profits. Demand ...
    • Stepwise Green Investment under Policy Uncertainty 

      Chronopoulos, Michail; Hagspiel, Verena; Fleten, Stein-Erik (Peer reviewed; Journal article, 2016)
      We analyse how market price and policy uncertainty, in the form of random provision or retraction of a subsidy, interact to affect the optimal time of Investment and the size of a renewable energy (RE) project that can be ...
    • Stepwise investment and capacity sizing under uncertainty 

      Chronopoulos, Michail; Hagspiel, Verena; Fleten, Stein-Erik (Peer reviewed; Journal article, 2016)
      The relationship between uncertainty and managerial flexibility is particularly crucial in addressing capital projects. We consider a firm that can invest in a project in either a single (lumpy investment) or multiple ...
    • Stochastic energy market equilibrium modeling with multiple agents 

      Brekke, Kjell Arne; Golombek, Rolf; Kaut, Michal; Kittelsen, Sverre A.C.; Wallace, Stein W. (Journal article, 2017)
    • 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 ...
    • 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 ...
    • 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 ...
    • Sulphur Abatement Globally in Maritime Shipping 

      Lindstad, Elizabeth; Rehn, Carl Fredrik; Eskeland, Gunnar (Journal article; Peer reviewed, 2017)
      In 2016, the International Maritime Organization (IMO) decided on global regulations to reduce sulphur emissions to air from maritime shipping starting 2020. The regulation implies that ships can continue to use residual ...
    • Tax-free digital news? 

      Foros, Øystein; Kind, Hans Jarle; Wyndham, Timothy G.A. (Journal article; Peer reviewed, 2019)
      News platforms are struggling. Their printed readership is predominantly old, and their digital product struggles to win the attention of the young. For several decades tax reductions have been used in Europe to increase ...
    • Testing for Granger causality in the presence of measurement errors 

      Andersson, Jonas (Journal article; Peer reviewed, 2005)
      In this paper a potential problem with tests for Granger−causality is investigated. If one of the two variables under study, but not the other, is measured with error the consequence is that tests of forecastablity of ...
    • The cost of multiple sclerosis in Norway 

      Svendsen, Bjørn; Myhr, Kjell-Morten; Nyland, Harald Inge; Aarseth, Jan Harald (Journal article; Peer reviewed, 2010)
      Health economic aspects have been increasingly important during introduction of new treatments for multiple sclerosis. As a partial response for Norway, a costof- illness study was carried out to estimate the yearly ...
