Does low price mean high competitiveness
PublicationWe found a strong positive relationship between Comparative Price Level Index (CPL) and Growth Competitiveness Index (GCI). We do realize that the relation we have found does not have to indicate cause and effects relationship. Competitiveness is a process which goes far beyond price level but it is detemined by lots of different elemnts. We show the GCI composition that provides a concept explaining what exactly determines competitiveness...

Noise and Rolling Resistance Properties of Various Types of Winter Tyres Compared to Normal Car Tyres
PublicationTo cope with winter weather conditions, potentially including snow and ice, it is common to use winter tyres, or ”all-seasons” tyres assumed to be safe both in summer and winter. In some northern countries, winter tyres are mandatory. Traditionally, it has been assumed that winter tyres are noisier than normal tyres (here called summer tyres) and winter tyres equipped with studs are assumed to be very noisy.This paper presents...
