In this paper a test is made of whether the Danish electricity producer, Elsam partly or fully exploits its temporary dominant position in hours of congestion at the Nordic electricity market. There seems to be evidences suggesting that Elsam is successful in pursuing its objective of having a...

This paper presents a new framework for coping with problems often encountered when modeling seasonal high frequency data containing both flow and stock variables. The idea is to apply a multivariate weekly representation of a daily periodic model and to exploit the possible cointegration and...

The paper considers the task of selecting a flexible nonlinear model which can be used as a baseline model. The baseline model may be used as a testing ground for more structural models which are congruent with economic theory. From the limited empirical evidence obtained here it is tentatively...

The main objective behind the production of seasonally adjusted time series is to give an easy access to a common time series data set purged of what is considered seasonal noise. Although the application of officially seasonally adjusted data may have the advantage of being cost saving it may...
