    • 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 ...

      Recently Beltran-Royo et.al presented a Semi-Lagrangean relaxation for the classical p-median location problem. The results obtained using the Semi-Lagrangean relaxation approach were quite impressive. In this paper we use ...
    • A Nodal Pricing Model for the Nordic Electricity Market 

      Bjørndal, Endre; Bjørndal, Mette; Gribkovskaia, Victoria (Discussion paper;43/14, Working paper, 2014-12)
      In the Nordic day-ahead electricity market zonal pricing or market splitting is used for relieving congestion between a predetermined set of bidding areas. This congestion management method represents an aggregation of ...
    • A partner in crime : assortative matching and bias in the crime market 

      Gavrilova, Evelina (Discussion papers;25/14, Working paper, 2014-06)
      I identify a discriminatory bias in partnership formation within the property crime mar- ket in the United States. Theoretically, the prisoner's dilemma creates an incentive for a criminal to form a partnership with a ...
    • A simple wavelet-based test for serial correlation in panel data models 

      Li, Yushu; Andersson, Fredrik N.G. (Discussion paper;11/14, Working paper, 2014-03)
      Hong and Kao (2004) proposed a panel data test for serial correlation of unknown form. However, their test is computationally difficult to implement, and simulation studies show the test to have bad small-sample properties. ...
    • 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 ...
    • 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 ...
    • Adjusting for Cell Suppression in Commuting Trip Data 

      Braathen, Christian; Thorsen, Inge; Ubøe, Jan (Discussion paper;13/22, Working paper, 2022-12-13)
      Maximum entropy methods are used to infer the true trip-distribution matrix in cases where parts of the data are suppressed due to privacy concerns. Large proportions of the suppressed data are found to be inferred correctly ...
    • 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 age-structured model for the effect of interest rate changes on consumption 

      Kozlov, Roman (Discussion paper;8/21, Working paper, 2021-08-30)
      A model for the effect of an interest rate change on household consumption is developed. The approach is age-structured: households reconsider their consumption patterns at the moment of the interest rate change and the ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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. ...
