    • 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 ...
    • Scrubber: a potentially overestimated compliance method for the Emission Control Areas - The importance of involving a ship's sailing pattern in the evaluation 

      Gu, Yewen; Wallace, Stein W. (Discussion paper;13/17, Working paper, 2017-10-30)
      Different methods for sulphur emission reductions, available to satisfy the latest Emission Control Areas (ECA) regulations, may lead to different sailing patterns (route and speed choices of a vessel) and thus have ...
    • 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 ...
    • 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 ...
    • Seasonality matters: a multi-season, multi-state dynamic optimization in fishery 

      Ni, Yuanming; Sandal, Leif K. (Discussion paper;2/18, Working paper, 2018-02-12)
      Many biological and economic processes in fishery happen seasonally. Most of the extant literature tends to neglect this fact. This work is an initial attempt to treat seasonality in a systematic and proper way. We apply ...
    • Seasoned public offerings: Resolution of the "new issues puzzle" 

      Eckbo, Espen B.; Masulis, Ronald W.; Norli, Øyvind (Discussion paper;09/98, Working paper, 1998)
      The `new issues puzzle' is that stocks of common stock issuers subsequently underperform non- issuers matched on size and book-to-market ratio. With 7,000+ seasoned equity and debt issues, we document that issuer ...
    • Secrecy Jurisdictions 

      Schjelderup, Guttorm (Discussion paper;12/15, Working paper, 2015-03-10)
      This paper surveys tax haven legislation and links the literature on tax havens to the literature on asymmetric information. I argue that the core aim of tax haven legislation is to create private information (secrecy) ...
    • Segmentation and pricing behavior in a market for certification 

      Hvide, Hans K. (Discussion paper, Working paper, 2002-11)
      The paper offers a simple theory of pricing behavior in certification markets. The basis for the theory is that certifiers offer differentiated tests; for an object of given quality it may be more difficult to pass the ...
    • Sequential Investment in Emerging Technologies under Policy Uncertainty 

      Sendstad, Lars Hegnes; Chronopoulos, Michail (Discussion paper;10/16, Working paper, 2016-06-14)
      Investment in emerging technologies is particularly challenging, since, apart from uncertainty in revenue streams, firms must also take into account both policy uncertainty and the random arrival of innovations. We assume ...
    • 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 ...
    • Sharing of endogenous risk in construction 

      Olsen, Trond E.; Osmundsen, Petter (Discussion paper, Working paper, 2003-07)
      In risk management of complex procurement projects in construction, the buyer has two principal instruments at his disposal: 1) the choice of time and resources put into engineering and design (project specification), thus ...
    • A short introduction to mathematical finance 

      Øksendal, Bernt (Discussion paper, Working paper, 1998)
      We give a brief survey of some fundamental concepts, methods and results in the mathematics of finance. The survey covers the 3 topics Chapter 1: Markets and arbitrages. The one-period model. The multi-period model. The ...

      Kiff, John; Kisser, Michael (Discussion paper, Working paper, 2011-04)
    • A simple approach to global optimal feedback solutions : with emphasize on certain management problems in economics 

      Sandal, Leif Kristoffer; Berge, Gerhard (Discussion paper, Working paper, 2001-06)
      Dynamic optimization problems covers a great class of problems in management science and technology. The classical problem formulations being the variational approach as in classical mechanics, like Hamilton's principle ...
    • A simple improvement of the IV estimator for the classical errors-in-variables problem 

      Andersson, Jonas; Møen, Jarle (Discussion paper, Working paper, 2009-09)
      Two measures of an error-ridden explanatory variable make it possible to solve the classical errors-in-variable problem by using one measure as an instrument for the other. It is well known that a second IV estimate can ...
