In the following we will analyse the sale of alcohol in Denmark. Various figures related to this question are published by Statistics Denmark at different frequencies. Our main concern will be with quarterly data for the sale of beer, wine and spirits from the period 1990 – 2004. Our two...

We study aggregation - or sample frequencies - of time series, e.g. aggregation from weekly to monthly or quarterly time series. Aggregation usually gives shorter time series but spurious phenomena, in e.g. daily observations, can on the other hand be avoided. An important issue is the effect of...

This paper examines the relation between monetary asset components and some of the variables that traditionally enter into aggregate money demand relations. This is done for Danish data within the natural framework of a multivariate econometric model. The purpose of the study is to investigate...

This study empirically investigates if competition’s impact on firm performance depends on the ownership structure. Our results show that an increase in import competition has a positive effect on firms with concentrated ownership and a negative effect on firms with dispersed ownership,...

This paper explores potential explanations behind the educational gap between young natives and immigrants using two measures, negative attitudes towards immigrants and networking, which may influence natives and immigrants differently. The paper considers, both theoretically and empirically,...
