  • Sampling risk evaluations in a tax fraud case: Some modelling issues 

    Lillestøl, Jostein (Discussion paper;5/20, Working paper, 2020-05-13)
    This work is a follow-up to Lillestøl (2019). The context is the use of sample data to support claims of tax fraud at eateries, where the possibilities of embezzlement are overreporting of take-away sales and underreporting ...
  • Software vulnerabilities and bug bounty programs 

    Bienz, Carsten; Juranek, Steffen (Discussion paper;4/20, Working paper, 2020-05-12)
    Many software developers employ bug bounty programs that award a prize for the detection of bugs in their software. We analyze, in a model with asymmetric information, under which conditions a bug bounty program is beneficial ...
  • Balanced scorecards: a relational contract approach 

    Kvaløy, Ola; Olsen, Trond E. (Discussion paper;3/20, Working paper, 2020-05-08)
    Reward systems based on balanced scorecards typically connect pay to an index, i.e. a weighted sum of multiple performance measures. However, there is no formal incentive model that actually describe this kind of index ...
  • The Effect of Social Distancing Measures on Intensive Care Occupancy: Evidence on COVID-19 in Scandinavia 

    Juranek, Steffen; Zoutman, Floris T. (Discussion paper;2/20, Working paper, 2020-04-29)
    Understanding the effectiveness of social distancing on the spread of COVID-19 is crucial to justify economically costly social distancing measures. We present a case study focusing on the three Scandinavian countries. ...
  • The Triple Difference Estimator 

    Olden, Andreas; Møen, Jarle (Discussion paper;1/20, Working paper, 2020-04-22)
    Triple difference has become a widely used estimator in empirical work. A close reading of articles in top economics journals reveals that the use of the estimator to a large extent rests on intuition. The identifying ...
  • Does a Wealth Tax Discriminate against Domestic Investors? 

    Bjerksund, Petter; Schjelderup, Guttorm (Discussion paper;16/19, Working paper, 2019-11-21)
    This paper studies the impact of a capital-income tax and a wealth tax on investor behavior in an efficient capital market under various assumptions regarding uncertainty and time horizons. We show that investors who face ...
  • Cooperation of customers in traveling salesman problems with profits 

    Osicka, Ondrej; Guajardo, Mario; Jörnsten, Kurt (Discussion paper;17/19, Working paper, 2019-11-22)
    The traveling salesman problem and its variants are among the most studied problems in the literature on transportation and logistics. In one of these variants known as the profitable tour problem [2], a profit-maximizing ...
  • MMP-elections and the assembly size 

    Stensholt, Eivind (Discussion paper;15/19, Working paper, 2019-10-30)
    MMP (Mixed Member Proportional) elections for legislatures have ballots with one vote in a local single seat tally and one vote for a party list in a multi-seat tally. In Germany, the multi-seat tally occasionally violated ...
  • On the economic geography of dual distribution - The case of McDonald’s in Germany 

    Freiwald, Nisa E.; Juranek, Steffen; Walz, Uwe (Discussion paper;14/19, Working paper, 2019-10-29)
    We analyze the allocation of ownership in a franchise system by focusing on location-specific characteristics of the outlets. This study uses a comprehensive data set on McDonald’s restaurants in Germany to investigate the ...
  • Analyzing learning effects in the newsvendor model by probabilistic methods 

    Andersson, Jonas; Jörnsten, Kurt; Lillestøl, Jostein; Ubøe, Jan (Discussion paper;13/19, Working paper, 2019-10-11)
    In this paper, we use probabilistic methods to analyze learning effects in a behavioral experiment on the newsvendor model. We argue why we should believe that suggested orders follow a multinomial logit distribution, and ...
  • Profit shifting and the effect of stricter transfer pricing regulation on tax revenue 

    Bakke, Julia Tropina; Hopland, Arnt Ove; Møen, Jarle (Discussion paper;11/19, Working paper, 2019-10-03)
    Using a 20-year-long, population-wide panel with detailed firm and group level data from Norway, we study the profitability change in companies that shift from being domestic to being multinational as well as companies ...
  • The impact of international tax information exchange agreements on the use of tax amnesty: evidence from Norway 

    Andersson, Jonas; Schroyen, Fred; Torsvik, Gaute (Discussion paper;12/19, Working paper, 2019-10-04)
    In this paper we develop a model for tax amnesty applications in a multi-period setting. One key insight from the model is that applying for amnesty becomes more attractive at the moment when stricter enforcement is ...
  • The optimal extraction rate versus the expected real return of a sovereign wealth fund 

    Aase, Knut K.; Bjerksund, Petter (Discussion paper;7/19, Working paper, 2019-09-06)
    With reference to funds established for the benefits of the public at large, a university endowment, or other similar sovereign wealth fund, we demonstrate that the optimal extraction rate from the fund is significantly ...
  • 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 ...
  • Markets With Memory: Dynamic Channel Optimization Models With Price-Dependent Stochastic Demand 

    Azad Gholami, Reza; Sandal, Leif K.; Ubøe, Jan (Discussion paper;8/19, Working paper, 2019-09-09)
    Almost every vendor faces uncertain and time-varying demand. Inventory level and price optimization while catering to stochastic demand are conventionally formulated as variants of newsvendor problem. Despite its ubiquity ...
  • Solution Algorithms for Optimal Buy-Back Contracts in Multi-period Channel Equilibria with Stochastic Demand and Delayed Information 

    Azad Gholami, Reza; Sandal, Leif K.; Ubøe, Jan (Discussion paper;10/19, Working paper, 2019-09-09)
    We analyze the problem of time-dependent channel coordination in the face of uncertain demand. The channel, composed of a manufacturer and a retailer, is to address a time-varying and uncertain price-dependent demand. The ...
  • Autonomous vessels: State of the art and potential opportunities in logistics 

    Gu, Yewen; Goez, Julio C.; Guajardo, Mario; Wallace, Stein W. (Discussion paper;6/19, Working paper, 2019-09-05)
    The growth in technology on autonomous transportation systems is currently motivating a number of research initiatives. This paper first presents a survey of the literature on autonomous marine vessels in general. By ...
  • Greed is good: from super-harvest to recovery in a stochastic predator-prey system 

    Ni, Yuanming; Sandal, Leif K.; Kvamsdal, Sturla F.; Poudel, Diwakar (Discussion paper;5/19, Working paper, 2019-09-04)
    This paper demonstrates a predator-prey system of cod and capelin that confronts a possible scenario of prey extinction under the first-best policy in a stochastic world. We discover a novel ‘super-harvest’ phenomenon that ...
  • Optimization of age-structured bioeconomic model: recruitment, weight gain and environmental effects 

    Ni, Yuanming (Discussion paper;4/19, Working paper, 2019-09-03)

  • Strategic Insider Trading in Continuous Time: A New Approach 

    Aase, Knut K.; Øksendal, Bernt (Discussion paper;3/19, Working paper, 2019-08-29)
    The continuous-time version of Kyle's (1985) model of asset pricing with asymmetric information is studied, and generalized by allowing time-varying noise trading. From rather simple assumptions we are able to derive the ...
