    • A Bellman approach to periodic optimization problems 

      Kvamsdal, Sturla F.; Maroto, José M.; Morán, Manuel; Sandal, Leif K. (Discussion paper;19/16, Working paper, 2016-11-30)
      We consider an infinite horizon optimization problem with arbitrary but finite periodicity in discrete time. The problem can be formulated as a fix-point problem for a contraction operator, and we provide a solution scheme ...
    • A bridge between continuous and discrete-time bioeconomic models: Seasonality in fisheries 

      Kvamsdal, Sturla F.; Maroto, José M.; Morán, Manuel; Sandal, Leif K. (Discussion paper;20/16, Working paper, 2016-11-30)
      We develop a discretization method for continuous-time bioeconomic models. Based on this method, we develop a discrete-time bioeconomic model to analyze seasonality in fisheries. The discretization method consists of three ...
    • Abusive transfer pricing and economic activity 

      Nielsen, Søren Bo; Schindler, Dirk; Schjelderup, Guttorm (Discussion papers;21/14, Working paper, 2014-05)
      This paper investigates how concealment costs of transfer pricing and the prob- ability of detection affect transfer pricing and firm behavior. We find that transfer pricing in intermediate production factors does not ...
    • A carbon footprint proportional to expenditure : a case for Norway? 

      Narbel, Patrick A.; Isaksen, Elisabeth T. (Discussion paper;16/14, Working paper, 2014-04)
      Assuming that emissions originate from the consumption of goods and services, we study the relationship between consumption-based per capita carbon footprint and per capita expenditure for Norway, using 2007 data. A ...
    • Access regulation and cross-border mergers : is international coordination beneficial? 

      Lommerud, Kjell Erik; Olsen, Trond E.; Straume, Odd Rune (Discussion paper, Working paper, 2005-04)
      The international integration of regulated markets poses new challenges for regulatory policy. One question is the implications that the overall international regulatory regime will have for cross-border and/or domestic ...
    • Adaptive regulation with flow and stock externalities 

      Sandal, Leif Kristoffer; Steinshamn, Stein Ivar (Discussion paper, Working paper, 1998-01)
      In confronting a consumer good whose production process is associated with both flow and stock externalities, a corrective tax is introduced to restore efficiency. The objective is to maximize social welfare over time when ...
    • Adverse selection, public information, and underpricing in new issues 

      Leite, Tore (Discussion paper, Working paper, 2004-02)
      This paper examines the role of adverse selection in the pricing of new issues when all investors may be privately informed about the firm, and in which public information is observed prior the issue date. The precision ...
    • Advertising and Newspaper Differentiation: On the Role of Readers’ Advertising Taste 

      Kind, Hans Jarle; Koethenbuerger, Marko; Schjelderup, Guttorm (Discussion paper, Working paper, 2007-01)
      Newspapers have an incentive to moderate their profile in order to gain a larger readership and thus higher advertising revenue. We show that this incentive is weakened both if readers are ad-haters and if they are ad-lovers.
    • An agent-based computational approach to explaining persistent spatial unemployment disparities 

      McArthur, David Philip; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2008-09)
      This paper explores possible reasons for persistent spatial unemployment disparities using agent-based computational methods. The method relies on observing the actions of thousands of individuals within an artificial ...
    • Aggregation of gravity models for journeys-to-work 

      Ubøe, Jan (Discussion paper, Working paper, 2001)
      This paper deals with the use of gravity models to examine journeys-to-work. The purpose of the paper is to study very simple examples demonstrating that gravity models may be subject to serious misspecification in aggregate ...
    • A likelihood ratio and Markov Chain based method to evaluate density forecasting 

      Li, Yushu; Andersson, Jonas (Discussion paper;12/14, Working paper, 2014-03)
      In this paper, we propose a likelihood ratio and Markov chain based method to evaluate density forecasting. This method can jointly evaluate the unconditional forecasted distribution and dependence of the outcomes. This ...
    • A maximum entropy approach to the newsvendor problem with partial information 

      Andersson, Jonas; Jörnsten, Kurt; Nonås, Sigrid Lise; Sandal, Leif Kristoffer; Ubøe, Jan (Discussion paper;2011:14, Working paper, 2011-08)
      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 ...
    • American derivatives : a review 

      Aase, Knut K. (Discussion paper, Working paper, 1997-12)
      The paper gives an overview over the theory of pricing and hedging financial derivatives that can be exercised at any time during a fixed time interval [0, T]. The analysis makes use of the theory of optimal stopping, and ...
    • American option pricing with transaction costs 

      Zakamouline, Valeri I. (Discussion paper, Working paper, 2003-10)
      In this paper we examine the problem of finding investors’ reservation option prices and corresponding early exercise policies of American-style options in the market with proportional transaction costs using the utility ...
    • Analysing flexible load contracts in the energy market 

      Lund, Arne-Christian; Ollmar, Fridthjof (Discussion paper, Working paper, 2002-11)
      In this paper we analyse flexible load contracts (FLC), a type of "swing" option. This contract type has existed in energy markets for a long time and has proved to be challenging to value. The term swing refers to the ...
    • An analysis of a combinatorial auction 

      Bjørndal, Mette; Jörnsten, Kurt (Discussion paper, Working paper, 2001)
      Our objective is to find prices on individual items in a combinatorial auction that support the optimal allocation of bundles of items, i.e. the solution to the winner determination problem of the combinatorial auction. ...
    • Analyzing risk of stock collapse in a fishery under stochastic profit maximization 

      Poudel, Diwakar; Sandal, Leif Kristoffer; Kvamsdal, Sturla Furunes (Discussion paper;2012:4, Working paper, 2012-04)
      In commercial fisheries, stock collapse is an intrinsic problem caused by overexploitation or due to pure stochasticity. To analyze the risk of stock collapse, we apply a relatively simple Monte Carlo approach which can ...
    • An Economic Analysis of Debarment 

      Auriol, Emmanuelle; Søreide, Tina (Discussion paper;23/15, Working paper, 2015-09-17)
      With a view to reducing the consequences of corruption in public procurement, many governments have introduced debarment of suppliers found guilty of corrup- tion and some other forms of crime. This paper explores the ...
    • A new Lagrangean Approach for the Travelling Salesman Problem 

      Jörnsten, Kurt; Kalcsics, Jörg (Discussion paper;04/15, Working paper, 2015-01-19)
      In this paper, we use a reformulation of the symmetric and the asymmetric travelling salesman problem more suitable for Lagrangean relaxation and analyse the new approach on examples from TSP Lib. Furthermore the Lagrangean ...
    • A New Semi-Lagrangean Relaxation for the K-Cardinality Assignment Problem 

      Belik, Ivan; Jörnsten, Kurt (Discussion paper;01/14, Working paper, 2014-01)
      Recently Beltrán-Royo, Vial & Alonso-Ayuso (2012) presented a semi-Lagrangean relaxation for the classical p-median location problem and for the incapacitated facility location problem. The results, obtained using the ...
