Recently, the seasonal characteristics of macroeconomic time series have drawn a lot of attention. It has been argued that the seasonal component of many macroeconomic time series constitutes a major part of the series measured as a proportion of the variance. In addition it has been found that...

Starting from a multivariate Wold representation for N variables that are integrated of order 1, this paper shows that, given that the N variables have r cointegrating vectors, there is an equivalence between five alternative representations of the multivariate model: the autoregressive...

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...

This paper aims at identifying and quantifying different sources of persistency in employment adjustment. Based on a dynamic labour market model an explicit distinction is made between real and nominal (prices and wage) propagation mechanisms. The theoretical analysis provides the basis for an...

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...
