Modeling heterogeneity in tripdistributions with partial information
Jörnsten, Kurt; Kleppe, Gisle; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2007)In this paper we propose a modified gravity model that takes into account that a population generally consists of heterogeneous groups, and we suggest a new statistical test for heterogeneity. We apply our new model to two ... 
Modelling social welfare effects of relocation and road pricing
Babri, Sahar; McArthur, David Philip; Thorsen, Inge; Ubøe, Jan (Discussion paper;42/14, Working paper, 201412)Road pricing is a popular congestion reduction strategy. However, there may be wider impacts associated with a road toll. We consider a factor which is sometimes overlooked, namely that workers and rms may choose to ... 
Optimum congestion pricing in a complex network
Babri, Sahar; McArthur, David Philip; Thorsen, Inge; Ubøe, Jan (Doctoral dissertation;04/13, Working paper, 201305)Road tolls are a well established way of dealing with problems of con gestion. Over recent years, the literature has expanded to take account of how congestion charges might interact with imperfections in other mar kets. ... 
Patient allocations according to circumstances and preferences: Modelling based on the Norwegian patient list system
Lillestøl, Jostein; Ubøe, Jan; Rønsen, Yngve; Hjortdahl, Per (Discussion paper, Working paper, 200612)In some countries every citizen has the right to obtain a designated general practitioner. However, each individual may have preferences that cannot be fulfilled due to shortages of some kind. The questions raised in this ... 
Patient allocations in general practice in case of patients' preferences for gender of doctor and their unavailability
Lillestøl, Jostein; Ubøe, Jan; Rønsen, Yngve; Hjortdahl, Per (Journal article; Peer reviewed, 2011)Background: In some countries every citizen has the right to obtain a designated general practitioner. However, each individual may have preferences that cannot be fulfilled due to shortages of some kind. The questions ... 
Probabilistic cost efficiency and bounded rationality in the newsvendor model
Ubøe, Jan; Andersson, Jonas; Jörnsten, Kurt; Lillestøl, Jostein; Sandal, Leif Kristoffer (Doctoral dissertation;41/14, Working paper, 201412)In this paper we establish a link between probabilistic cost efficiency and bounded rationality in the newsvendor model. This establishes a framework where bounded rationality can be examined rigorously by statistical ... 
Properties of the gold price : an investigation using fractional Brownian motion and supervised machine learning techniqes
Røine, Theodor Bruu; Holter, Edvard Kvalø (Master thesis, 2018)This thesis investigates properties of the gold price. Two different aspects have been analyzed using two different methods. The concept of fractional Brownian motion has been utilized in the search for evidence of long ... 
Replication/prediction problems in the journeytowork
Jörnsten, Kurt; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2002)In this paper we will consider gravity models for journeystowork. In applications of the theory it is sometimes assumed that the parameters in such models are fixed. We will provide examples to show that this is not ... 
Revelation of preferences in patient list data
Ubøe, Jan; Lillestøl, Jostein (Discussion paper, Working paper, 2007)In this paper we will show how the patient list model in Ubøe & Lillestøl (2007) can be used to infer strength of preferences from patient list data. We prove that we can construct unique sets of preferences that replicates ... 
Revelation of preferences in trip distribution models
Jörnsten, Kurt; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2007)In this paper we will see how commuter preferences can be revealed from observations of trip distributions. We will explain how to find unique representations of preference structures leading to an observed trip distribution, ... 
Solution Algorithms for Optimal BuyBack Contracts in Multiperiod Channel Equilibria with Stochastic Demand and Delayed Information
Azad Gholami, Reza; Sandal, Leif K.; Ubøe, Jan (Discussion paper;10/19, Working paper, 20190909)We analyze the problem of timedependent channel coordination in the face of uncertain demand. The channel, composed of a manufacturer and a retailer, is to address a timevarying and uncertain pricedependent demand. The ... 
Some aspects of random utility, extreme value theory and multinomial logit models
Andersson, Jonas; Ubøe, Jan (Journal article; Peer reviewed, 2012)In this paper we give a survey on some basic ideas related to random utility, extreme value theory and multinomial logit models. These ideas are well known within the eld of spatial economics, but do not appear to be ... 
Some aspects of random utility, extreme value theory and multinomial logit models
Andersson, Jonas; Ubøe, Jan (Discussion paper, Working paper, 201001)In this paper we give a survey on some basic ideas related to random utility, extreme value theory and multinomial logit models. These ideas are well known within the eld of spatial economics, but do not appear to be ... 
A spatial equilibrium simulation approach to explain unemployment rate differentials between areas
Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 2002)This paper primarily focuses on how areaspecific asymmetries and exogenous shocks influence spatial unemployment disparities. We approach through a model specification with two areas and two categories of workers with ... 
The spatial transferability of parameters in a gravity model of commuting flows
McArthur, David Philip; Kleppe, Gisle; Thorsen, Inge; Ubøe, Jan (Discussion paper, Working paper, 201005) 
Stackelberg equilibria in a multiperiod vertical contracting model with uncertain and pricedependent demand
Sandal, Leif Kristoffer; Ubøe, Jan (Discussion paper;2012:2, Working paper, 201202)In this paper, we consider Stackelberg games in a multiperiod vertical contracting model with uncertain demand. Demand has a distribution with a mean and variance that depend on the current retail price, and this ... 
Stackelberg equilibria in continuous newsvendor models with uncertain demand and delayed information
Øksendal, Bernt; Sandal, Leif Kristoffer; Ubøe, Jan (Journal article; Peer reviewed, 2014)We consider explicit formulae for equilibrium prices in a continuoustime vertical contracting model. A manufacturer sells goods to a retailer, and the objective of both parties is to maximize expected profits. Demand ... 
Stochastic Stackelberg equilibria with applications to time dependent newsvendor models
Sandal, Leif Kristoffer; Øksendal, Bernt; Ubøe, Jan (Discussion paper, Working paper, 201105) 
Stochastic Stackelberg equilibria with applications to timedependent newsvendor models
Øksendal, Bernt; Sandal, Leif Kristoffer; Ubøe, Jan (Journal article; Peer reviewed, 2013)In this paper, we prove a maximum principle for general stochastic differential Stackelberg games, and apply the theory to continuous time newsvendor problems. In the newsvendor problem, a manufacturer sells goods to a ... 
Strategic Pricing of Commodities
Jörnsten, Kurt; Ubøe, Jan (Journal article; Peer reviewed, 2009)We consider a setting where a large number of agents are trading commodity bundles. Assuming that agents of the same type have a certain utility attached to each transaction, we construct a statistical equilibrium which ...
