  We analyze optimal risk sharing between a customer and an in surer, and present alternative explanations for the prevalence of kinks in Pareto optimal contracts, like deductibles and upper bounds as in XL-contracts. Linear ...

• Optimal Insurance Policies and Saving in a Temporal World 

  Aase, Knut K. (Discussion paper;7/25, Working paper, 2025-02-25)

  We consider Pareto optimal risk sharing between a buyer and a seller of insurance contracts, as well as consumption substitution and saving in a two-period context. The separation of the time periods allows us to consider ...

• Recursive utility and jump-diffusions 

  Aase, Knut K. (Discussion paper;6/25, Working paper, 2025-02-24)

  We consider agents in an exchange economy having preferences represented by scale invariant recursive utility, where the dynamics of both consumption and risky assets are given by jump-diffusions. In this setting we find ...

• Optimal risk sharing with translation invariant recursive utility for jump-diffusions 

  Aase, Knut K. (Discussion paper;5/25, Working paper, 2025-02-21)

  We consider optimal risk sharing where agents have preferences represented by translation invariant recursive utility. The dynamics in continuous time is driven by diffusion processes and a random jump measure. The model ...

• The Cost of Weather: Modeling Weather Delay in Bulk Shipping 

  Enerstvedt, Vegard (Discussion paper;4/25, Working paper, 2025-02-04)

  Weather is an ever-present factor influencing shipping operations at every stage, including port operations. This paper examines the determi nants of weather-induced delays in port operations, the probability and duration ...

• Addressing Congestion in Time-Expanded Networks: A Lifeboat Allocation Model for Maritime Evacuations 

  Velez, Andres (Discussion paper;02/25, Working paper, 2025-01-24)

  This paper addresses the challenge of congestion in time-expanded networks, focusing on a case study related to maritime evacuations. The problem is made complex by an endogenous relationship between inputs and outputs, ...

• Hydrogen in Renewable-Intensive Energy Systems: Path to Becoming a Cost-Effective and Efficient Storage Solution 

  Qu, Chunzi; Bang, Rasmus Noss; Sandal, Leif K.; Steinshamn, Stein Ivar (Discussion paper;01/25, Working paper, 2025-01-13)

  This paper examines the integration of hydrogen storage in renewable-intensive energy systems. Current hydrogen storage technology is too costly and inefficient, but reducing hydrogen costs to 12.5% of current levels and ...

• Smart charging costs in the times of the energy price crisis 

  Brockmann, Fabian; Guajardo, Mario (Discussion paper;13/24, Working paper, 2024-12-28)

  This paper examines how the impact of flexibility in electric vehicle (EV) charging has evolved over recent years. In contrast to previous studies that focus on shorter time frames, our analysis spans from 2019 to 2023. ...

• Taxation and Multi-Sided Platforms: A Review 

  Kind, Hans Jarle; Schjelderup, Guttorm (Discussion paper;12/24, Working paper, 2024-12-20)

  Many of the largest and most influential industries in the global economy operate digitally as multi-sided platforms, catering to different groups who are connected through intergroup network effects. This paper provides ...

• European Grid Development Modeling and Analysis: Established Frameworks, Research Trends, and Future Opportunities 

  Qu, Chunzi; Bang, Rasmus Noss (Discussion paper;11/24, Working paper, 2024-10-31)

  This paper presents a comprehensive survey of recent literature on European energy system modeling and analysis with special focus on grid development. Spanning the years from 2013 to 2023, we analyze 59 selected articles, ...

• Integrated maritime fuel management with stochastic fuel prices and new emission regulations 

  Gu, Yewen; Wallace, Stein W.; Wang, Xin (Peer reviewed; Journal article, 2018)

• Stochastic Network Design for Planning Scheduled Transportation Services: The Value of Deterministic Solutions 

  Wang, Xin; Crainic, Teodor Gabriel; Wallace, Stein W. (Peer reviewed; Journal article, 2018)

  We study the value of deterministic solutions, in particular their quality and upgradability, in addressing stochastic network design problems, by analyzing their time-dependent formulations known as scheduled service ...
