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...

We test econometrically whether the sole Danish producer of cement holds a dominant position in the Danish market for (grey) cement. In import penetration tests, we find that its pricing and quantity decisions are independent of import price and quantity, implying that it can act to a...
