Optimal control of predictive mean-field equations and applications to finance
(Peer reviewed; Journal article, 2016)We study a coupled system of controlled stochastic differential equations (SDEs) driven by a Brownian motion and a compensated Poisson random measure, consisting of a forward SDE in the unknown process X(t) and a predictive ... -
Tax-adjusted Discount Rates: a General Formula under Constant Leverage Ratios
(Peer reviewed; Journal article, 2013)Cooper and Nyborg (2008) derive a tax-adjusted discount rate formula under a constant proportion leverage policy, investor taxes and risky debt. However, their analysis assumes zero recovery in default. We extend their ... -
Optimal control of systems with noisy memory and BSDEs with Malliavin derivatives
(Journal article; Peer reviewed, 2016)In this article we consider a stochastic optimal control problem where the dynamics of the state process, X(t), is a controlled stochastic differential equation with jumps, delay and noisy memory. The term noisy memory ... -
Planning for charters: A stochastic maritime fleet composition and deployment problem
(Peer reviewed; Journal article, 2017)This paper introduces a chartering problem that arises in the shipping industry. The chartering decisions determine the time-charter contracts to enter into, in particular, how many ships of each type to charter in, and ... -
A Maximum Principle for Mean-Field SDEs with Time Change
(Journal article; Peer reviewed, 2017)Time change is a powerful technique for generating noises and providing flexible models. In the framework of time changed Brownian and Poisson random measures we study the existence and uniqueness of a solution to a ... -
A Donsker delta functional approach to optimal insider control and applications to finance
(Journal article; Peer reviewed, 2015)We study optimal insider control problems, i.e. optimal control problems of stochastic systems where the controller at any time t, in addition to knowledge about the history of the system up to this time, also has ... -
The impact of regional environmental regulations on empirical vessel speeds
(Journal article; Peer reviewed, 2017)Economic theory suggests that the use of more expensive low-sulphur fuel within an Emission Control Area (ECA) should result in lower vessel speeds. The objective of this paper is to investigate empirically, for the first ... -
Market-specific Sunk Export Costs: The Impact of Learning and Spillovers
(Journal article; Peer reviewed, 2017)Firms may face sunk costs when entering an export market. Previous studies have focused on global or country-specific sunk export costs. This study analyses the importance of market-specific sunk export costs (defining ... -
Sulphur Abatement Globally in Maritime Shipping
(Journal article; Peer reviewed, 2017)In 2016, the International Maritime Organization (IMO) decided on global regulations to reduce sulphur emissions to air from maritime shipping starting 2020. The regulation implies that ships can continue to use residual ... -
Approximate Bayesian inference for spatial econometrics models
(Journal article; Peer reviewed, 2014)In this paper we explore the use of the Integrated Laplace Approximation (INLA) for Bayesian inference in some widely used models in Spatial Econometrics. Bayesian inference often relies on computationally intensive ... -
Stepwise Green Investment under Policy Uncertainty
(Peer reviewed; Journal article, 2016)We analyse how market price and policy uncertainty, in the form of random provision or retraction of a subsidy, interact to affect the optimal time of Investment and the size of a renewable energy (RE) project that can be ... -
Environmental regulations in shipping: Policies leaning towards globalization of scrubbers deserve scrutiny
(Peer reviewed; Journal article, 2016)ABSTRACT Emission regulations for Sulphur oxides (SOx) and nitrogen oxides (NOx) are motivated by health- and other environmental objectives in local and regional settings, while global warming concerns motivate policies ... -
Stepwise investment and capacity sizing under uncertainty
(Peer reviewed; Journal article, 2016)The relationship between uncertainty and managerial flexibility is particularly crucial in addressing capital projects. We consider a firm that can invest in a project in either a single (lumpy investment) or multiple ... -
Stochastic energy market equilibrium modeling with multiple agents
(Journal article, 2017) -
Optimal Insurance Policies in the Presence of Costs
(Journal article; Peer reviewed, 2017)We reconsider costs in insurance, and suggest a new type of cost function, which we argue is a natural choice when there are relatively small, but frequent, claims. If a fixed cost is incurred each time a claim is made, ... -
Prosessledelse og innovasjon: En litteraturstudie
(Journal article, 2013)Denne artikkelen studerer hvilken innvirkning prosessledelse har på bedrifters innovasjonsevne. Artikkelen deler prosessledelse inn i seks dimensjoner, og det gjøres en litteraturstudie for å avdekke sammenhengen mellom ... -
Påvirker kjønn forhandlinger?
(Journal article; Peer reviewed, 2017)Det synes å være en utbredt oppfatning at kvinner er dårlige til å forhandle. Nyere internasjonal forskning viser imidlertid at det er små forskjeller mellom kvinner og menn. Og det avgjørende er hvorvidt forhandlingssituasjonen ... -
Dead Battery? Wind Power, the Spot Market, and Hydropower Interaction in the Nordic Electricity Market
(Journal article; Peer reviewed, 2013)It is well established within both the economics and power system engineering literature that hydropower can act as a complement to large amounts of intermittent energy. In particular hydropower can act as a “battery” where ... -
Scrapping a wind turbine: Policy changes, scrapping incentives and why wind turbines in good locations get scrapped first
(Journal article; Peer reviewed, 2014)The most common reason for scrapping a wind turbine in Denmark is to make room for a newer turbine. The decision to scrap a wind turbine is then highly dependent on an opportunity cost that comes from the interaction of ... -
Individuelle priser i dagligvaremarkedet
(Journal article; Peer reviewed, 2017)Bedrifter har fått større mulighet til å samle informasjon om hver enkelt kunde. I dagligvaremarkedet samler kjedene informasjon om hvor og hva vi handler. NorgesGruppen og Coop har i mange år hatt rabattprogrammer hvor ...
