10 - Hotel Tourism
(Working paper, 2007-10-11)Topic: Factor analysis and Discriminant analysis Context: This case is based on answers of questionnaires given to tourists at hotels in three different regions of Norway, here named Valleyland, Fjordland and ... -
12 - Cashier Fraud
(Working paper, 2007-10-13)Topic: Variation and extremes Context : This case deals with cashier fraud at a supermarket, involv¬ing so-called “return money” when the cashiers have to correct errors. The supermarket in question has 16 cashiers, ... -
20 - Customer Satisfaction
(Working paper, 2007-10-21)Topics: Possible methods of analysis are: Cross tabulation - chisquare tests Analysis of variance Regression analysis Factor analysis Discriminant analysis Cluster analysis Context: For producers of ... -
9 - Breakfast Cereal
(Working paper, 2007-10-10)Topic: Cluster analysis and alternatives Context: The following data (units omitted) on the content of 23 different brands of breakfast cereal were read from the packages found in two food stores in Bergen in the ... -
A Bellman approach to periodic optimization problems
(Discussion paper;19/16, Working paper, 2016-11-30)We consider an infinite horizon optimization problem with arbitrary but finite periodicity in discrete time. The problem can be formulated as a fix-point problem for a contraction operator, and we provide a solution scheme ... -
A bridge between continuous and discrete-time bioeconomic models: Seasonality in fisheries
(Discussion paper;20/16, Working paper, 2016-11-30)We develop a discretization method for continuous-time bioeconomic models. Based on this method, we develop a discrete-time bioeconomic model to analyze seasonality in fisheries. The discretization method consists of three ... -
A carbon footprint proportional to expenditure : a case for Norway?
(Discussion paper;16/14, Working paper, 2014-04)Assuming that emissions originate from the consumption of goods and services, we study the relationship between consumption-based per capita carbon footprint and per capita expenditure for Norway, using 2007 data. A ... -
A likelihood ratio and Markov Chain based method to evaluate density forecasting
(Discussion paper;12/14, Working paper, 2014-03)In this paper, we propose a likelihood ratio and Markov chain based method to evaluate density forecasting. This method can jointly evaluate the unconditional forecasted distribution and dependence of the outcomes. This ... -
A maximum entropy approach to the newsvendor problem with partial information
(Discussion paper;2011:14, Working paper, 2011-08)In this paper, we consider the newsvendor model under partial information, i.e., where the demand distribution D is partly unknown. We focus on the classical case where the retailer only knows the expectation and variance ... -
A new Lagrangean Approach for the Travelling Salesman Problem
(Discussion paper;04/15, Working paper, 2015-01-19)In this paper, we use a reformulation of the symmetric and the asymmetric travelling salesman problem more suitable for Lagrangean relaxation and analyse the new approach on examples from TSP Lib. Furthermore the Lagrangean ... -
A New Semi-Lagrangean Relaxation for the K-Cardinality Assignment Problem
(Discussion paper;01/14, Working paper, 2014-01)Recently Beltrán-Royo, Vial & Alonso-Ayuso (2012) presented a semi-Lagrangean relaxation for the classical p-median location problem and for the incapacitated facility location problem. The results, obtained using the ... -
A new Semi-Lagrangean Relaxation for the p-median problem
(Discussion paper;01/15, Working paper, 2015-01-09)Recently Beltran-Royo et.al presented a Semi-Lagrangean relaxation for the classical p-median location problem. The results obtained using the Semi-Lagrangean relaxation approach were quite impressive. In this paper we use ... -
A Nodal Pricing Model for the Nordic Electricity Market
(Discussion paper;43/14, Working paper, 2014-12)In the Nordic day-ahead electricity market zonal pricing or market splitting is used for relieving congestion between a predetermined set of bidding areas. This congestion management method represents an aggregation of ... -
A partner in crime : assortative matching and bias in the crime market
(Discussion papers;25/14, Working paper, 2014-06)I identify a discriminatory bias in partnership formation within the property crime mar- ket in the United States. Theoretically, the prisoner's dilemma creates an incentive for a criminal to form a partnership with a ... -
A simple wavelet-based test for serial correlation in panel data models
(Discussion paper;11/14, Working paper, 2014-03)Hong and Kao (2004) proposed a panel data test for serial correlation of unknown form. However, their test is computationally difficult to implement, and simulation studies show the test to have bad small-sample properties. ... -
Abusive transfer pricing and economic activity
(Discussion papers;21/14, Working paper, 2014-05)This paper investigates how concealment costs of transfer pricing and the prob- ability of detection affect transfer pricing and firm behavior. We find that transfer pricing in intermediate production factors does not ... -
Access regulation and cross-border mergers : is international coordination beneficial?
(Discussion paper, Working paper, 2005-04)The international integration of regulated markets poses new challenges for regulatory policy. One question is the implications that the overall international regulatory regime will have for cross-border and/or domestic ... -
Adaptive regulation with flow and stock externalities
(Discussion paper, Working paper, 1998-01)In confronting a consumer good whose production process is associated with both flow and stock externalities, a corrective tax is introduced to restore efficiency. The objective is to maximize social welfare over time when ... -
Adjusting for Cell Suppression in Commuting Trip Data
(Discussion paper;13/22, Working paper, 2022-12-13)Maximum entropy methods are used to infer the true trip-distribution matrix in cases where parts of the data are suppressed due to privacy concerns. Large proportions of the suppressed data are found to be inferred correctly ... -
Adverse selection, public information, and underpricing in new issues
(Discussion paper, Working paper, 2004-02)This paper examines the role of adverse selection in the pricing of new issues when all investors may be privately informed about the firm, and in which public information is observed prior the issue date. The precision ...
