    • Estimation of biological and economic parameters of a bioeconomic fisheries model using dynamical data assimilation 

      Ussif, Al-Amin M.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 2000-05)
      A new approach of model parameter estimation is used with simulated measurements to recover both biological and economic input parameters of a natural resource model. The procedure efficiently combines time series of ...
    • European market integration for gas? : volume flexibility and political risk 

      Asche, Frank; Osmundsen, Petter; Tveterås, Ragnar (Discussion paper, Working paper, 2000-05)
      Is the European gas market integrated? Are there substantial price differences between gas from different export countries? Time series of Norwegian, Dutch and Russian gas export prices to Germany in 1990-1998 are examined. ...
    • European option pricing and hedging with both fixed and proportional transaction costs 

      Zakamouline, Valeri I. (Discussion paper, Working paper, 2002-12)
      In this paper we extend the utility based option pricing and hedging approach, pioneered by Hodges and Neuberger (1989) and further developed by Davis, Panas, and Zariphopoulou (1993), for the market where each transaction ...
    • Evidence on competitive advantage and superior stock market performance 

      Gjerde, Øystein; Knivsflå, Kjell Henry; Sættem, Frode (Discussion paper, Working paper, 2009-10)
      This article analyzes the value-relevance of industry-based and resource-based competitive advantage in a large sample of firms listed on the Oslo Stock Exchange. We measure competitive advantage by a single variable and ...
    • Evolution of Decision and Control Rights in Venture Capital Contracts: An Empirical Analysis 

      Bienz, Carsten; Walz, Uwe (Discussion paper, Working paper, 2006-12)
      We analyze the structure and evolution of the allocation of decision and control rights in venture capital contracts by using a sample of 464 contracts between venture capitalists (VC) and portfolio firms from Germany. We ...
    • Evolutionary stable investment in stock markets 

      Evstigneev, Igor V.; Hens, Thorsten; Schenk-Hoppé, Klaus Reiner (Discussion paper, Working paper, 2003-10)
      This paper studies the performance of portfolio rules in incomplete markets for long-lived assets with endogenous prices. The dynamics of wealth shares in the process of repeated reinvestment of wealth is modelled as a ...
    • Existence and uniqueness of equilibrium in a reinsurance syndicate 

      Aase, Knut K. (Discussion paper, Working paper, 2008-07)
      In this paper we consider a reinsurance syndicate, assuming that Pareto optimal allocations exist. Under a continuity assumption on preferences, we show that a competitive equilibrium exists and is unique. Our conditions ...
    • Existence of sunspot equilibria and uniqueness of spot market equilibria : the case of intrinsically complete markets 

      Hens, Thorsten; Mayer, Janós; Pilgrim, Beate (Discussion paper, Working paper, 2004)
      We consider economies with additively separable utility functions and give conditions for the two-agents case under which the existence of sunspot equilibria is equivalent to the occurrence of the transfer paradox. This ...
    • Explicit Solution Algorithms for Order and Price Postponement in Multi-periodic Channel Optimization 

      Azad Gholami, Reza; Sandal, Leif K.; Ubøe, Jan (Discussion paper;9/19, Working paper, 2019-09-09)
      Supply channels typically face uncertain and time-varying demand. Nonetheless, time-dependent channel optimization while addressing uncertain demand has received limited attention due to the high level of complexity of the ...
    • Extensions of an integrated approach for multi-resource shop scheduling 

      Dauzère-Pérès, Stéphane; Pavageau, Claire (Discussion paper, Working paper, 1999-06)
      In a previous work, we proposed an integrated approach for a rather general shop scheduling problem, with multi-resource, exibility and non-linear routings. In this paper, we want to overcome some of the limitations of the ...
    • Fat and skew : can NIG cure? : on the prospects of using the normal inverse Gaussian distribution in finance 

      Lillestøl, Jostein (Discussion paper, Working paper, 1998-03)
      This paper explores the possibility of using the Normal Inverse Gaussian (NIG) distribution introduced by Barndorff-Nielsen (1997) in various problem areas in finance where distributions often are found to be non-normal ...
    • Financial Distress and Idiosyncratic Volatility: An Empirical Investigation 

      Chen, Jing; Chollete, Lorán (Discussion paper, Working paper, 2006-07)
      We address the twin puzzles of anomalously low returns for high idiosyncratic volatility and high distress risk stocks, documented by Ang, Hodrick, Xing and Zhang (2006) and Campbell, Hilscher and Szilagyi (2005), respectively. ...
    • Financial economics 

      Aase, Knut K. (Discussion paper, Working paper, 2003-01)
      We consider a one period (two time points-) model of efficient risk sharing, when the risk of possible sharing rules are constrained to be linear. This can be interpreted as a model of a market for common stocks. Here we ...
    • Finding core allocations for fixed cost games in electricity networks 

      Bjørndal, Endre; Stamtsis, Georgios C.; Erlich, István (Discussion paper, Working paper, 2003)
      We discuss the cost allocation problem faced by a network operator, where the fixed (residual) cost of the network has to be allocated among its users. Usage-based methods, such as the postage stamp rate method and the ...
    • Finding the Right Yardstick: Regulation under Heterogeneous Environments 

      Bjørndal, Endre; Bjørndal, Mette; Cullmann, Astrid; Nieswand, Maria (Discussion paper;4/16, Working paper, 2016-02-25)
      Revenue cap regulation is often combined with systematic benchmarking to reveal the managerial inefficiencies when regulating natural monopolies. One example is the European energy sector, where benchmarking methods are ...
    • Firm size and the quality of entrepreneurs 

      Hvide, Hans K. (Discussion paper, Working paper, 2004-06)
      A theory is proposed where the pay policy and size of established firms are determined together with individual workers' entrepreneurship decision. The main results are twofold. First, taking the firm size as given, larger ...
    • Fish wars on the high seas : a straddling stock competition model 

      McKelvey, Robert W.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 2001-04)
      The post World War II era saw the development of powerful self-contained fishing fleets, so-called distant-water fleets (DWFs), which roamed the worlds oceans, seeking out rich harvesting targets wherever they might be ...
    • Fisheries management under irreversible investment : does stochasticity matter? 

      Poudel, Diwakar; Sandal, Leif Kristoffer; Kvamsdal, Sturla Furunes; Steinshamn, Stein Ivar (Discussion paper;2011:20, Working paper, 2011-11)
      We present a continuous, nonlinear, stochastic and dynamic model for capital investment in the exploitation of a renewable resource. Both the resource stock and capital stock are treated as state variables. The resource ...
    • Flow-Based Market Coupling in the European Electricity Market – A Comparison of Efficiency and Feasibility 

      Bjørndal, Endre; Bjørndal, Mette; Cai, Hong (Discussion paper;14/18, Working paper, 2018-10-23)
      In May 2015, the Flow-Based Market Coupling (FBMC) model replaced the Available Transfer Capacity (ATC) model in Central Western Europe to determine the power transfers between countries or price areas. The FBMC model aims ...
    • Foreclosure in contests 

      Clark, Derek J.; Foros, Øystein; Sand, Jan Yngve (Discussion paper, Working paper, 2008-12)
      We consider a contest in which one firm is a favourite as it initially has a cost advantage over rivals. Instead of taking the set of rivals as given, we consider the possibility that the favourite transfers the source ...
