Tytuł	Porównanie udziału w eksporcie produktów spożywczych, napojów, tytoniu w Polsce i w wybranych krajach UE mierzonego wartością dodaną
Title	Comparison of Share in the Export of Food, Beverages, Tobacco in Poland and in Selected EU Countries Measured by Value Added
Słowa kluczowe	handel międzynarodowy, przemysł spożywczy, handel wartością dodaną, globalne łańcuchy wartości, GVC
Key words	international trade, food industry, value-added trade, global value chains, GVC
Abstrakt	Celem artykułu jest wskazanie różnic w liczeniu udziału poszczególnych gałęzi produkcyjnych w eksporcie, w zależności od danych przyjętych do obliczeń, na przykładzie produktów spożywczych, napojów i tytoniu. Dane te mogą być statystykami przedstawiającymi eksport mierzony brutto jak i w ujęciu wartości dodanej. W związku z rozwojem powiązań gospodarczych między krajami i uczestnictwem w globalnych łańcuchach wartości, statystyki prezentujące eksport krajowej wartości dodanej precyzyjniej obrazują znaczenie poszczególnych gałęzi dla gospodarek badanych krajów. Porównania udziałów w eksporcie w ujęciu tradycyjnym i wartości dodanej pozwalają wskazać gałęzie, których znaczenie jest przeszacowywane lub nieoszacowywane w statystykach brutto.
Abstract	The aim of the article is to indicate differences in counting the share of exports for individual branches of production, based on the data used for the calculation, on the example of food, beverages and tobacco. Statistics can measure exports in two ways: gross export and in terms of value added. In connection with the development of economic ties between countries and participation in global value chains, statistics presenting exports of domestic value added illustrate more precisely the importance of particular industries for the economies of different countries. Comparisons of export shares in traditional and value-added terms helps to show those branches whose importance is overestimated or underestimated in gross statistics.

Tytuł	Change in Seasonality Pattern of EU Farmgate Milk Price
Title	Change in Seasonality Pattern of EU Farmgate Milk Price
Słowa kluczowe	farmgate milk price, seasonality, forecasting, globalization, panel regressions
Key words	farmgate milk price, seasonality, forecasting, globalization, panel regressions
Abstrakt	Since 2007 farmgate milk prices in EU have become much more volatile and their seasonal pattern has stopped being so explicit. The purpose of this research is to test the hypothesis that seasonality still plays an important role in shaping farmgate milk prices in EU while its amplitude decreases together with the growing integration of the EU milk market with the global market. The aforementioned issues are investigated using Census X-12 procedure of price decomposition and panel random effects model. The results indicate that after 2007 the role of seasonality in determining EU farmgate milk prices has significantly decreased which partially results from the higher integration of the EU milk market with the global market. Nevertheless, seasonality remains an important factor determining the farmgate milk prices in EU. It can be expected that with the further globalization of the milk market, the significance of seasonality in determining farmgate milk prices in EU will be diminishing.
