Does one currency mean one price? An analysis of the euro effect on price dispersion and convergence
PublikacjaThis paper examines price differentials in the European Union to investigate whether the European Monetary Union has lowered the degree of price dispersion in the euro zone and increased the speed of price convergence. Both euro effects are evaluated using difference-in-difference methodology. Applied to the issue of introducing a single currency, the euro effects identified are the estimated differences in price dispersion and...

One Europe, one product, two prices - the price disparity in the EU
PublikacjaThe price dispersion in the European Union in the last fifteen years (1990-2005) is analysed. The analysis of price convergence is examined on aggregate and disaggregate levels. The macro approach is based on Comparative Price Level index calculated as the ratio between PPPs and exchange rate. The disaggregate analysis utilizesactual prices of 148 individual products sold in the 15 capital cities of the EU. The calculations comprise...

20+ years of Polish residential real estate prices – a house price index proxy
PublikacjaInformation on house prices is often considered crucial when assessing developments in economy. However, in Poland for the long time house prices haven’t been tracked in an organized manner. Recent developments, most notably house price indices developed by Poland’s national bank and by the statistical office do not go back more than 10 years, therefore data series are relatively short compared to those of other macroeconomic data. In...

Price Diversification
PublikacjaThe price diversification is a complex phenomenon. We show that price discrimination can have both positive and negative effects. The final result depends whether it makes competition more intense. As far as legal procedure is cocerned it is recommended to focus on the effects of compan's actions rather than on the form that these actions may take. There is a need to understand and distinguish between price discrimination as the...

Equilibrium price - modelling, forecast and application
PublikacjaNowoczesną gospodarkę charakteryzuje wzrastające znaczenie cen. Znajomość ogólnych zasad mechanizmu kształtującego ceny oraz analizy cen umożliwiają przedsiębiorstwom przewidzenie ceny równowagi i podjęcie przynoszącej zyski decyzji, zwłaszcza na rynku oligopolu homogenicznego, gdzie przedsiębiorcy muszą brać pod uwagę reakcję konkurencji. Przedstawiony w artykule, dynamiczny model ekonometryczny cen benzyny, na rynku paliw płynnych...

Dispersion compensation in optical coherence tomography
PublikacjaDyspersja wprowadzana przez system optycznej tomografii koherentnej (OCT) oraz badane obiekty powoduje zniekształcenia fazowe w zależności od długości fali widma promieniowania zastosowanego źródła optycznego. powoduje to rozmycie obrazów otrzymanych przekrojów badanych materiałów pogarszając właściwości metrologiczne systemu OCT. W artykule przedstawiono metody kompensacji dyspersji w systemie OCT oraz przedyskutowano ich właściwości.

Does low price mean high competitiveness
PublikacjaWe 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...

Price convergence in the EU-an aggregate and disaggregate approach
PublikacjaThis article examines the price dispersion in the European Union (EU) over 15 years (1990-2005). An extensive overview of the literature offers inconclusive results with the half-lives of price shocks from 2.8 to 282 months. Until now, most of the empirical research has been either micro or macro based. In contrast, we conducted a complex analysis utilizing both aggregate and disaggregate price data. The macro approach is based...

Does one currency mean one price?
PublikacjaEuropean Monetary Union was expected to have many consequences for the economies of participant countries. Theory suggested that through a higher volume of trade and stronger competition in the Eurozone, a single currency would lead to a reduction in price dispersion. As far as prices are concerned, two effects were expected: an immediate effect due to the technical characteristics of the changeover process, and a long-term one...

The impact of European Monetary Union on Price Convergence.
PublikacjaArtykuł dotyczy skutków wprowadzenia wspólnej waluty euro. Bada zarówno skutki krótkookresowe tj. odczucia co do podwyżek cen przez konsumentów i inflację w okresie przejścia na jedna walutę, jak i skutki długookresowe związane z redukcją kosztów tranzakcyjnych, eliminacją ryzyka kursowego i większą przejrzystością cen.

Curves of thermodynamic states in some fluids with dispersion
Publikacjavariations in the thermodynamic state of a dispersive medium, caused by sound, are studied. A bubbly liquid and a Maxwell fluid are considered as examples. Curves in the plane of thermodynamic states are plotted. They are in fact pictorial images of linear relations of excess pressure and excess density in the acoustic wave which reflect irreversible attenuation of the sound energy. The curves account for the nonlinear generation...

Price convergence in the European Union and in the new member states
PublikacjaThis paper examines price dispersion in the European Union (EU15) and in three New Member States (Poland, Hungary and the Czech Republic) between 1995 and 2006. The analysis utilizes both disaggregate and aggregate price data, including the prices of 157 products and two indices constructed using two different weighting procedures. For each category of goods the price dispersion is lower in EU15 than EU15 plus 3 NMS. Sigma convergence...
