Well-to-tank carbon emissions from crude oil maritime transportation
(Peer reviewed; Journal article, 2020)International seaborne transport of crude oil takes place mainly on tankers, with annual seaborne crude flows totaling an estimated 12 billion barrels. To take into account the carbon footprint on crude oil from its ... -
The value of timecharter optionality in the drybulk market
(Peer reviewed; Journal article, 2020)Using an optimization model on a network with stochastic travel times we estimate the value of flexible worldwide redelivery compared to the more constrained Atlantic ocean option. We evaluate the value of the redelivery ... -
Understanding the marginal distributions and correlations of link travel speeds in road networks
(Peer reviewed; Journal article, 2020)Link travel speeds in road networks are essential data for a variety of research problems in logistics, transportation, and traffic management. Real-world link travel speeds are stochastic, and highly dependent on speeds ... -
Kyle equilibrium under random price pressure
(Peer reviewed; Journal article, 2019)We study the equilibrium in the model proposed by Kyle (Econometrica 53(6):1315–1335, 1985) and extended to the continuous-time setting by Back (Rev Financ Stud 5(3):387–409, 1992). The novelty of this paper is that we ... -
Will the locals benefit? The effect of wind power investments on rural wages
(Peer reviewed; Journal article, 2020) -
Sequential investment in renewable energy technologies under policy uncertainty
(Journal article; Peer reviewed, 2019) -
Vehicle Routing with Space- and Time-Correlated Stochastic Travel Times: Evaluating the Objective Function
(Peer reviewed; Journal article, 2019)We study how to model and handle correlated travel times in two-stage stochastic vehicle-routing problems. We allow these travel times to be correlated in time and space; that is, the travel time on one link in one period ... -
Handling financial risks in crude oil imports: Taking into account crude oil prices as well as country and transportation risks
(Journal article; Peer reviewed, 2019)Financial risks related to crude oil imports are certainly affected by crude oil price uncertainty. Our question is: How important is it to take also physical risks, such as the crude oil exporters’ political risks and ... -
Hedging ship price risk using freight derivatives in the drybulk market
(Journal article; Peer reviewed, 2019)We show that a fixed-maturity time-weighted Forward Freight Agreement (FFA) portfolio should be used to proxy the expected future earnings of a vessel. We investigate the corresponding hedging efficiency when using a ... -
On the approximation of Lévy driven Volterra processes and their integrals
(Journal article; Peer reviewed, 2019)Volterra processes appear in several applications ranging from turbulence to energy finance where they are used in the modelling of e.g.temperatures and wind and the related financial derivatives. Volterra processes are ... -
Problem-driven scenario generation: an analytical approach for stochastic programs with tail risk measure
(Journal article; Peer reviewed, 2019)Scenario generation is the construction of a discrete random vector to represent parameters of uncertain values in a stochastic program. Most approaches to scenario generation are distribution-driven, that is, they attempt ... -
When energy efficiency is secondary: The case of Offshore Support Vessels
(Journal article; Peer reviewed, 2019)Offshore Support Vessels (OSVs) deal with time-sensitive logistics and sophisticated marine operations for high-value offshore oil and gas installations. We investigate whether this creates preferences that effectively ... -
Tax-free digital news?
(Journal article; Peer reviewed, 2019)News platforms are struggling. Their printed readership is predominantly old, and their digital product struggles to win the attention of the young. For several decades tax reductions have been used in Europe to increase ... -
The Need to Amend IMO’s EEDI to Include a Threshold for Performance in Waves (Realistic Sea Conditions) to Achieve the Desired GHG Reductions
(Peer reviewed; Journal article, 2019)The International Maritime Organization (IMO) has established the Energy Efficiency Design Index (EEDI) as the most important policy measure to reduce greenhouse gas (GHG) emissions from shipping. A vessel’s EEDI is based ... -
Internasjonal skatteplanlegging – er åpenhet en utopi?
(Peer reviewed; Journal article, 2018)Skatteparadis, aggressiv skatteplanlegging og rettslige hybrider er komplekse fenomener som blant annet brukes av multinasjonale selskaper for å unndra og minimere skatt. Disse selskapenes komplekse selskapsstrukturer og ... -
Economies of scale in Norwegian electricity distribution: a quantile regression approach
(Journal article; Peer reviewed, 2018) -
An analysis of maintenance schedules for public facilities
(Journal article; Peer reviewed, 2019)We present a flexible, formal framework for maintenance scheduling for public facilities. Key features of the model include an accelerating deterioration scheme, a general utility measure, and real estate market effects ... -
A Likelihood Ratio and Markov Chain Based Method to Evaluate Density Forecasting
(Journal article; Peer reviewed, 2019)In this paper, we propose a likelihood ratio based method to evaluate density forecasts which can jointly evaluate the unconditional forecasted distribution and dependence of the outcomes. Unlike the well‐known Berkowitz ... -
Predators in the market: implications of market interaction on optimal resource management
(Journal article; Peer reviewed, 2017)A two-species bioeconomic model is analyzed, but in contrast to most similar models, there is no biological interaction between the species, only economic. The interaction takes place in the market where the quantity of ... -
Relational Contracts, Multiple Agents, and Correlated Outputs
(Journal article; Peer reviewed, 2019)We analyze relational contracts between a principal and a set of risk-neutral agents whose outputs are correlated. When only the agents’ aggregate output can be observed, a team incentive scheme is shown to be optimal, ...
