    • Earnings announcements and the variability of stock returns 

      Eilifsen, Aasmund; Knivsflå, Kjell Henry; Sættem, Frode (Discussion paper, Working paper, 1999)
      This paper is concerned with the dissemination process of firm-specific annual earnings information in the Norwegian capital market. We find a significant reduction in stock price volatility in the post-announcement period ...
    • Weight functions and sign regularity 

      Manne, Per Erik; Tungodden, Bertil (Discussion paper, Working paper, 1999-03)
      We examine the question of how the ranking between different distributions with respect to a one-parameter family of weight functions depend on the parameter. We argue that in this context sign regularity of the family of ...
    • Using lagrangean relaxation to minimize the (weighted) number of late jobs on a single machine 

      Dauzère-Pérès, Stéphane; Sevaux, Marc (Discussion paper, Working paper, 1999-06)
      This paper tackles the general single machine scheduling problem, where jobs have different release and due dates and the objective is to minimize the weighted number of late jobs. The notion of master sequence is first ...
    • On the importance of sequencing decisions in production planning and scheduling 

      Dauzère-Pérès, Stéphane; Lasserre, Jean-Bernard (Discussion paper, Working paper, 1999-06)
      We discuss the traditional hierarchical approach to production planning and scheduling, emphasizing the fact that scheduling constraints are often either ignored or considered in a very crude way. In particular, we point ...
    • 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 ...
    • Strategic tax competition : implications of national ownership 

      Olsen, Trond E.; Osmundsen, Petter (Discussion paper, Working paper, 1999-11)
      Two jurisdictions compete to capture the rents of a large multinational enterprise (MNE) which invests locally and which is partly owned by local investors. The MNE contributes to local welfare by tax payments and dividends, ...
    • Valuation of irreversible investments : private information about the investment cost 

      Mæland, Jøril (Discussion paper, Working paper, 1999-11)
      This article examines dynamic investment decisions when there is an agency problem. A principal delegates the decision of an investment strategy of a project to an agent. The agent has private information about the investment ...
    • Investing without credible inter-period regulations : a bargaining approach with application to investments in natural resources 

      Nordal, Kjell Bjørn (Discussion paper, Working paper, 1999-12)
      A government’s lack of credibility when promising future taxation and regulation of foreign direct investment is often regarded as an obstacle to foreign investment. As shown in this paper, the total lack of inter-period ...
    • Paradoxes in networks supporting competitive electricity markets 

      Bjørndal, Mette; Jörnsten, Kurt (Discussion paper, Working paper, 2000)
      Grid investments are normally done in electrical networks in order to achieve a well functioning integrated electricity market and/or making the network more secure, i.e. less sensitive to link failures. In general, there ...
    • A disaggregated gravity model 

      Gitlesen, Jens Petter; Jörnsten, Kurt (Discussion paper, Working paper, 2000)
      The gravity model is used to estimate trip distributions. The estimates are in form of trip frequencies. This study is devoted to an entropy problem where the solution decomposes trip frequencies to the underlying probability ...
    • Viewing the deregulated electricity market as a bilevel programming problem 

      Bjørndal, Mette; Jörnsten, Kurt (Discussion paper, Working paper, 2000)
      In this paper we present a bilevel programming formulation of a deregulated electricity market. By looking at a deregulated electricity market in this format we achieve two things, the relation between a deregulated ...
    • Guaranteed investment contracts: distributed and undistributed excess return 

      Miltersen, Kristian R.; Persson, Svein-Arne (Discussion paper, Working paper, 2000)
      Annual minimum rate of return guarantees are analyzed together with rules for distribution of positive excess return, i.e. investment returns in excess of the guaranteed minimum return. Together with the level of the annual ...
    • Valuation and risk management in the Norwegian electricity market 

      Bjerksund, Petter; Rasmussen, Heine; Stensland, Gunnar (Discussion paper, Working paper, 2000)
      The purpose of this paper is two-fold: Firstly, we analyze option value approximation of traded options in the presence of a volatility term structure. The options are identified as: "European" (written on the forward price ...
    • Single transferable votes with tax-cuts 

      Stensholt, Eivind (Discussion Paper, Working paper, 2000)
      Some tally methods for preferential elections are discussed from the following point of view: how well do they respect a wish from the voter that subsidiary votes in the ballot cannot hurt the chances of the ballot’s ...
    • Disposal of petroleum installations : major policy issues 

      Osmundsen, Petter; Tveterås, Ragnar (Discussion paper, Working paper, 2000-01)
      Following the Brent Spar controversy, the OSPAR countries reached a unanimous agreement in 1998 for the future rules for disposal of petroleum installations. The vast majority of existing offshore installations will be ...
    • International competition for R&D investments 

      Olsen, Trond E.; Osmundsen, Petter (Discussion paper, Working paper, 2000-02)
      Two jurisdictions compete to attract shares of the R&D investment budget of a large multinational enterprise, whose investments potentially confer positive spillovers on national firms. The firm contributes to local welfare ...
    • Leverage, liquidity and long-run IPO returns 

      Eckbo, B. Espen; Norli, Øyvind (Discussion paper, Working paper, 2000-02)
      It is well known that IPO stocks on average substantially underperform (over 3-5 years) non-IPO stocks matched on firm size. With a large sample of Nasdaq IPOs, this paper presents systematic evidence that IPO stocks are ...
    • A new approach of fitting biomass dynamics models to real data based on a linear total allowable catch (TAC) rule : an optimal control approach 

      Ussif, Al-Amin M.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 2000-05)
      A non-traditional approach of fitting dynamic resource biomass models to data is developed in this paper. The adjoint technique is an optimal control or a variational method for parameter identification. It provides a novel ...
    • Assimilation of real time series data into a dynamic bioeconomic fisheries model : an application to the Norwegian cod fishery stock 

      Ussif, Al-Amin M.; Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 2000-05)
      This paper combines the new and elegant technique of inverse methods and a Monte Carlo procedure to analyze real data for the Norwegian cod fishery (NCF) stock. A simple nonlinear dynamic resource model is calibrated to ...
    • Perspectives of risk sharing 

      Aase, Knut K. (Discussion paper, Working paper, 2000-05)
      In this paper we present an overview of the standard risk sharing model of insurance. We discuss and characterize a competitive equilibrium, Pareto optimality, and representative agent pricing, including its implications ...
