Tytuł	COGNITIVE MODELLING OF AN EFFECTIVE SYSTEM OF INFORMATION SUPPORT OF AGRICULTURAL ENTERPRISES
Title
Słowa kluczowe	information support, cognitive approach, modelling, forecasting, poorly structured system, cognitive modelling of efficiency of functioning of the information system of agricultural entrepreneurship
Key words
Abstrakt	This article encompasses the methodology of cognitive modelling of complex poorly structured systems. Based on the expert method and with the help of this modelling methodology, the main factors that influence the effectiveness of information support of agricultural entrepreneurship were identified and the direction of their action was determined. There has been developed a cognitive map that reflects the cumulative impact of various factors on each other, as well as on the effectiveness of the information system for agricultural entrepreneurship. Hidden patterns between factors influencing the effectiveness of information support of agricultural entrepreneurship are revealed based on the cognitive map. The scenario approach is simulated based on different trends that reflect the current situation. This model allows us to further evaluate the performance of the system of information support of agricultural entrepreneurship under the influence of the environment, to predict its development, as well as to develop optimal strategic decisions that are aimed at ensuring sustainable development.

Title
Słowa kluczowe	bioeconomy, agriculture, biotechnologies, bioresources, strategies
Key words
Abstrakt	The article examines the role of the bioeconomy in the formation of priorities for the economic development of Ukraine. It is determined that the primary goal of the bioeconomy is the optimal use of renewable biological resources and the creation of sustainable manufacturing systems for new products. It is noted that Ukraine belongs to the countries with high bioeconomic potential, the source of which is the production of biomass of agricultural origin that creates favorable conditions for the development of the bioeconomy. The dynamics of biomass production potential are characterized by a stable increase in the amount of biomass available for use, and its energy capacity is analysed. Using the methodology of 'smart specialization', a model of strategy formation was developed, which defines the priorities, goals, and objectives of the bioeconomic development of Ukraine's economy.

Tytuł	Wpływ zmian klimatu na efektywność wykorzystywania azotu oraz jego straty
Title	The Impact of Climate Change on the Efficiency of Nitrogen Use and its Losses
Słowa kluczowe	zmiany klimatu, plony, efektywność, azot, straty
Key words	climate change, yield, NUE, nitrogen, losses
Abstrakt	Celem badań było określenie przewidywanych plonów, efektywności wykorzystania N (NUE), wymywania N, emisji N2O i NH3 w zależności od zmian klimatu do 2050 r. Badania wykonano, z zastosowaniem modelu DNDC, dla okresów lat 1991-2010, 2011-2030 i 2031-2050 oraz 10 lokalizacji w Polsce. W symulacjach uwzględniono zmianowanie roślin: kukurydza na ziarno – jęczmień jary – rzepak ozimy – pszenica ozima, które uprawiano na glebach lekkich, średnich i ciężkich, przy nawożeniu wynoszącym odpowiednio: 140, 90, 160 i 120 kg N ha-1. Stwierdzono, że zmiany klimatu przyczynić się mogą do wzrostów plonów kukurydzy na ziarno (6-43%) i rzepaku ozimego (2-8%), spadków plonów pszenicy ozimej (od -18 do -5%) oraz nieistotnych zmian w plonach jęczmienia jarego. NUE wzrośnie w uprawie kukurydzy (2-17%), zmaleje w uprawach pszenicy ozimej (3-22%) i jęczmienia jarego (3-17%) oraz nie ulegnie zmianie w przypadku rzepaku ozimego. Zmiany NUE oraz straty N nie wpływały na konieczność zmniejszenia dawek azotu w przyszłej uprawie badanych roślin.
Abstract	The aim of the study was to determine the expected yields, the efficiency of N (NUE) use, N leaching, N2O and NH3 emissions depending on climate change until 2050. The research was carried out using the DNDC model for the years 1991-2010, 2011-2030 and 2031-2050 as well as 10 locations in Poland. In the simulations, the crop rotation were considered: maize for grain - spring barley - winter rape - winter wheat, which was grown on light, medium and heavy soils, with fertilization of, respectively: 140, 90, 160 and 120 kg N ha-1. It was found that climate change can contribute to increase in the yield of maize (6-43%) and winter rape (2-8%), decreases in winter wheat yield (from -18 to -5%) and negligible changes in yields of spring barley. NUE will increase in the cultivation of maize (2-17%), it will decrease in winter wheat (3-22%) and spring barley (3-17%) crops and will not change in the case of winter oilseed rape. NUE changes and N losses did not affect the need to reduce nitrogen doses in the future cultivation of the studied plants.

Title	Price Behaviour and Market Integration: Preliminary Evidencefrom the Ukrainian and European Union Rapeseed Markets
Słowa kluczowe	price behavior, horizontal market integration, Ukraine, European Union, rapeseed market
Key words	price behavior, horizontal market integration, Ukraine, European Union, rapeseed market
Abstrakt	This paper aims to provide preliminary evidence about the existence of horizontal integration between the rapeseed markets in Ukraine (UA) and the European Union (EU). To this end, both a trade analysis and a price analysis were carried out. In particular, the trade analysis was performed using yearly trade flows between the UA and EU, whereas price co-movement was assessed by means of linear vector error correction model (VECM) applied to weekly prices for rapeseed from 2008 to 2018. Our findings provide evidence of strong integration between the UA and EU markets in terms of the trade of rapeseeds, rape cake, and rape oil, as well as high horizontal rapeseed price transmission between the two economies.

Title	Financial Sustainability and Value of Joint-Stock Companies from Food Industry in Central and Eastern Europe
Słowa kluczowe	financial sustainability, value, food industry, Central and Eastern Europe
Key words	financial sustainability, value, food industry, Central and Eastern Europe
Abstrakt	The research presents the analysis of relations between financial sustainability and value of joint-stock companies from food industry in Central and Eastern Europe. Increase of volume of assets, shareholders’ equity and revenues demonstrated an improvement of financial sustainability and resulted in growing valuations of companies in the study period. Sample business entities achieved relatively high liquidity and profitability that proved their financial sustainability in terms of risk and return. At the same time rising operating profit margins and liquidity ratios determined higher enterprise value of joint-stock companies. This emphasized a positive relation between enterprise value and financial sustainability. Joint-stock companies demonstrated a robust capital structure with a minor decrease of corporate debt in 2011-2015. However changes in sources of financing could provoke a trade-off between financial sustainability and enterprise value. According to a regression model factors positively influencing enterprise value included revenue, cash and cash equivalents, operating profit, current liabilities and shareholder’s equity. Stimulating revenue and increasing operating profit as well as maintaining higher cash balances improves financial sustainability while debt extension can significantly deteriorate continuity of business.

Title	Effects of Certain Personal Attributes on Food Waste
Słowa kluczowe	food waste, consumer attitude, sustainable consumption
Key words	food waste, consumer attitude, sustainable consumption
Abstrakt	With the increase of food supply and the improvement of production processes, the real value of certain food products has been steadily declining over the past decades, which is certainly a trend that has seriously transformed the moral value of food, its role in society and its associated personal attitudes. According to UN and FAO estimates, in 2016, 30-35% of our food was wasted. Food waste in households is also a special area of research in terms of their high wasting rate. While exploring the causes of high amounts of consumer waste, a research group has also correlated (with mathematical models) the gradual growth rate of food waste, the US obesity epidemic and the growing supply of cheaper food products (Hall et al. 2009). In our research, we examine certain personal aspects in case of specific (e.g. functional) foods as well. A significant decrease in food waste coming from households could be attained by controlling our attitudes. Food waste, consumption awareness, eating habits, food mileage, water footprint, sustainable eating, energy efficiency: these are all terms which have to have their meaning and importance taught to people, as they contain important – affecting the level of wasting – information. Therefore, we can see that food waste itself is one of the most serious, paradoxical and global modern issues which the developed world has identified, and is trying to decrease by using national and international interventions in order to limit food supply anomalies and environmental loads as much as possible. Understanding personal attributes more precisely might be a good practice for providing future solutions, as well.

Title	Verification of the Possibilities to Reduce Ammonia Emission for Various Slurry Application Practices in Poland
Słowa kluczowe	rolnictwo, gnojowica, amoniak, emisje, ograniczenie emisji
Key words	agriculture, slurry, ammonia, emission, emission reduction
Abstrakt	Rolnictwo polskie zobowiązane jest do redukcji emisji amoniaku (NH3), w stosunku do 2005 r., o 1% corocznie w latach 2020-29 oraz o 17% corocznie od 2030 r. Znaczącym źródłem emisji jest stosowanie gnojowicy. W Polsce aplikuje się ją głównie rozbryzgowo na powierzchnię pola i przyoruje po 4-24 godzinach od aplikacji. W pracy zastosowano model ALFAM2 do scharakteryzowania emisji NH3 z rozbryzgowego stosowania gnojowicy w zależności od specyficznych dla Polski: dawek gnojowicy, jej suchej masy, temperatury powietrza, prędkości wiatru, opadów oraz pH gnojowicy. W stosunku do emisji NH3 z gnojowicy stosowanej na powierzchnię pola oszacowano emisje powstające przy aplikacji gnojowicy za pomocą wężów wleczonych, wężów z redlicami oraz aplikacji do otwartych szczelin, płytko doglebowo i głęboko doglebowo. Na podstawie uzyskanych wyników oszacowano wielkości redukcji emisji dla podstawowych praktyk jej aplikacji.
Abstract	Polish agriculture is obliged to reduce ammonia (NH3) emissions, compared to 2005, by 1% annually in 2020-29 and by 17% annually from 2030. A significant source of emissions is the use of slurry. In Poland, it is mainly broadcast on the field surface and incorporated 4-24 hours after application. The ALFAM2 model was used to characterize the NH3 emissions from the slurry broadcast depending on the specific parameters for Poland: doses of slurry, its dry matter, air temperature, wind speed, precipitation and the pH of the slurry. In relation to the NH3 emission from the slurry applied broadcast to the field surface, the emissions resulting from the application of slurry by trailing hoses, trailing shoe, open slot injection, shallow and deep injection were estimated. On the basis of the obtained results, the emission reduction values were estimated for the basic practices of its application.

Title	Adoption Spells of Improved Potato Varieties by Smallholder Farmers in Eastern Ethiopia: The Duration Approach
Słowa kluczowe	adoption spell, Weibull, static, potato varieties, Ethiopia
Key words	adoption spell, Weibull, static, potato varieties, Ethiopia
Abstrakt	Potato is mainly tagged as a food security crop in Ethiopia. However, its productivity remains low due to low adoption of improved technologies by smallholder farmers. Duration models, namely, Parametric (Weibull) and Non-parametric (Kaplan Meier) were used to analyze the data gathered from 365 sample farmers. The Non-parametric result revealed that the average duration that potato growers should wait before adopting a new variety is about 3.5 years. The Weibull regression indicated that timely availability of seed, access to labor and irrigation water, land size, and adaptation strategy by farmers are found to be factors curtailing the timeframe to adopt improved potato varieties. The regression analysis revealed that costs of inputs such as manure and compost, environmental and market factors such as drought, pest and disease outbreaks, price variability of potato seed, and quality of potato seed were found to be factors influencing adoption decisions of improved potato varieties by smallholder farmers.

Title	Planned Shape of the CAP 2021-2027 versus Globalisation and Integration Processes
Słowa kluczowe	common agricultural policy, globalisation, integration
Key words	common agricultural policy, globalisation, integration
Abstrakt	The planned CAP reform will determine the capacity of EU agriculture in facing challenges, especially those related to climate change and growing international competition. The aim of the paper is to assess the EC’s reform proposals in the context of globalisation and integration processes. The paper is based on the analysis of the EC’s proposals for the CAP 2021-2027. The results show that the proposed changes in the CAP are limited and they do not ensure significant support for the agricultural sector. They also are not adequately precise to evaluate them. Moreover, the proposed change in the CAP implementation model poses a serious risk of the CAP disintegration, which will not help the EU in its trade talks with other partners and thus can be detrimental to the future of the EU agri-food sector. It seems that the first step to make the CAP more effective is to strengthen its monitoring system.

Title
Słowa kluczowe	business, environment, reputation, market, barriers
Key words	biznes, środowisko, renoma, rynek, bariery
Abstrakt	The main aim of this paper is analyzed the role, importance and methodology for creating the strategies for international competition, as well as the ways of implementing and evaluating the selected strategies. This is done by applying exploratory, descriptive and casual methods to outperform competitors and determine the scope of an enterprise’s engagement in international business. The article examines forces and steps of planning, implementing and evaluating a business strategy. Enterprises must recognize and compare the factors that compose foreign environments, especially the state and local governmental politics, legal regulations, economic and financial forces, cultural differences, business ethics, technological development, infrastructure, natural resources protections, sociological and demographic issues. Three competitive strategies have been distinguished: cost leadership, differentiation and focus. Virtues of M. Porter’s five forces model: threat of new entry, competitive rivalry, supplier power, buyer power and threat of substitutes have been considered. The selection of the target markets and recognizing customers preferences belong to the most important tasks of strategic planning. An enterprise can select three levels of international involvement: passive participation, active involvement and taking the international position. Foreign countries impose barriers on international trade, but international agreements facilitate healthy competition.
Abstract	Głównym celem artykułu jest analiza roli, znaczenia i metodologii opracowywania koncepcji strategii międzynarodowego biznesu oraz sposobów wdrażania i oceny wybranych strategii. Realizacja tego zadania została przeprowadzona przez zastosowanie badań odkrywczych, rozstrzygających i przyczynowych. Przedstawiono, metody pokonania konkurentów i skale zaangażowania przedsiębiorstwa w prowadzenie międzynarodowego biznesu. Artykuł rozpatruje czynniki determinujące międzynarodową przewagę konkurencyjną i etapy jej planowania, wdrażania i oceny. Przedsiębiorstwa musza poznać i porównywać czynniki determinujące obce środowisko, a w szczególności krajowa politykę regulacje prawne, czynniki ekonomiczne i finansowe, różnice kulturowe, etykę prowadzenia biznesu, postęp technologiczny, infrastrukturę, ochronę naturalnego środowiska oraz kwestie społeczne i demograficzne. Wyniki analizy pozwoliły na wyróżnienie najbardziej cenionych przedsiębiorstw na świecie. Trzy strategie konkurowania zostały omówione: lidera niskich kosztów, dywersyfikacji i koncentracji. Wyróżniono walory pięciu czynników konkurencji M. Portera: nasilenia istniejącej konkurencji, zagrożenia ze strony nowych konkurentów, negocjacyjnej siły dostawców, negocjacyjnej siły nabywców i zagrożenia pojawienia się nowych substytutów. Wybór rynków docelowych i rozpoznanie preferencji konsumentów stanowi ważny element planowania strategicznego. Przedsiębiorstwo może dokonać wyboru trzy poziomy międzynarodowego zaangażowania: udział bierny, aktywne zaangażowanie i ustalenie pozycji międzynarodowej. Obcy kraj może nakładać bariery na handel międzynarodowy, lecz międzynarodowe porozumienia ułatwiają wolną konkurencje.

Abstrakt	Branża pocztowa, której tradycyjnym produktem są list i paczka, traktowana jest obecnie jako część szerszego rynku KEP (kurier, ekspres, paczka). Dla rynku KEP można zidentyfikować zjawiska rozwojowe (megatrendy) mające wpływ na jego funkcjonowanie w dłuższej perspektywie. Wiedza o tych zjawiskach powinna być podstawą każdej decyzji o strategicznym charakterze.Celem opracowania jest usystematyzowanie istoty zmian w otoczeniu branży pocztowej. Niektóre zjawiska w otoczeniu tego rynku już przyczyniły się do komodyzacji (utraty wartości i konieczności redefinicji podstawowych założeń) niektórych rodzajów usług, a w odniesieniu do innych, do ich całkowitego zniknięcia z rynku. Megatrendy w otoczeniu branży pocztowej decydują o tym, że publiczni operatorzy stoją dzisiaj przed koniecznością zmiany modeli funkcjonowania. Być może, w niedalekiej przyszłości, konieczność zmian będzie dotyczyć także paradygmatów zarządzania. Artykuł podejmuje tematykę branży pocztowej z perspektywy wyzwań w zakresie zarządzania, gdzie zauważyć można istotną lukę w polskim piśmiennictwie. Opracowanie ma charakter teoretyczny z aspektami praktycznymi i jest oparty na przeglądzie literatury naukowej oraz popularno-naukowej. W artykule dokonano aktualizacji literatury z punktu widzenia obecnego stanu rzeczy branży pocztowej. Wykorzystano wtórne źródła danych.
Abstract	The postal industry, whose historical product are letter and parcel, is now treated as a part of the wider CEP market (courier, express, parcel). It is possible to identify, for the CEP market, development phenomena (megatrends) affecting its long-term functioning. The knowledge of these phenomena should be the basis for any strategic decision. The aim of the study is to systematize the essence of changes taking place in the environment of the postal industry. Some phenomena, surrounding this market, have already contributed to the commodization (the loss of value and the need to redefine the basic assumptions) of the certain types of services, and in relation to others, to their complete disappearance from the market. Megatrends in the environment of the postal industry decide that public operators face nowadays the necessity to change their operating models. Perhaps, in the near future, the need for a change will also apply to management paradigms. The article addresses the subject of the postal industry from the perspective of management challenges, where one can notice a significant gap in Polish literature. The study has a theoretical character with practical aspects and is based on a review of scientific and popular science literature. The article updates the literature taking into account the current state of the postal industry`s affairs. Secondary data sources were used.

Abstrakt	Celem artykułu było rozwiązanie dwóch problemów: czy dla trzech wyróżnionych punktów krytycznych czyli jednostkowego kosztu dopuszczalnego, nakładów inwestycyjnych dopuszczalnych i dopuszczalnej ceny za najnowszą technologię można sformułować twierdzenia ściśle ogólne, które w poprzedniku okresów warunkowych zawierają założenia (warunki), dla których w ich następniku wskaźniki finansowe osiągają wielkości oznaczające uzyskanie sukcesu finansowego w wyniku wdrożenia inwencji, oraz czy jest możliwe zastosowanie trzech podstawowych twierdzeń TC do badania opłacalności przedsięwzięć innowacyjnych, polegających na wdrożeniu inwencji w rolnictwie. Takie twierdzenia, pełniące rolę diagnostyczną i wspomagającą podejmowanie decyzji zostały sformułowane. Rozwiązano również drugi problem w wyniku określenia dla fazy przedprodukcyjnej wdrożenia nowoczesnej szklarni do produkcji pomidorów w ruchu ciągłym, że za pomocą trzech podstawowych twierdzeń TC można sprawdzić, czy spełnione są warunki osiągnięcia sukcesu finansowego i na tej podstawie podjąć poprawną decyzję o wdrożeniu tej inwencji. Głównymi narzędziami badawczymi były trzy modele strategiczne wdrożenia tej inwencji, które jednocześnie były dyskontowymi modelami symulacyjnymi. Zastosowano również dodatki Excela Szukaj wyniku i Solver.
Abstract	The aim of the article was to solve two problems: whether for three critical points, i.e. a unit allowable cost, allowable investment outlays and an allowable price for the latest technology, it is possible to formulate strictly general theorems which in the predecessor of conditional periods contain assumptions (conditions) for which in their successor financial ratios reach values, meaning financial success achievement as a result of the implementation of the invention, and whether it is possible to apply the three TC basic theorems to the analysis of the profitability of innovative projects, based on the implementation of inventions in agriculture. Such theorems, performing the diagnostic role and supporting decision-making were formulated. The second problem was also solved for the pre-production phase of the implementation of a modern greenhouse for continuous tomato production, that with three basic TC theorems it is possible to test whether the conditions for achieving financial success are met and, on this basis, make the correct decision to implement this invention. The main research tools were three strategic models of implementation of this invention, which were also discount simulation models. Excel What, if and Solver adds-inn were also applied.

Słowa kluczowe	wydajność pracy, rolnictwo, modele deterministyczne, Unia Europejska
Key words	labour productivity, agriculture, deterministic models, European Union
Abstrakt	Celem pracy było przedstawienie przemian wydajności pracy w rolnictwie Unii Europejskiej (UE) w latach 2005-2016 oraz propozycji metodycznej dekompozycji wskaźnika wydajności pracy w rolnictwie. W zaproponowanych trzech modelach dekompozycji wydajności pracy uwzględniono siedem czynników (wskaźników), tj. produktywność nakładów, produktywność ziemi, wskaźnik wartości dodanej, opodatkowanie produkcji, dopłaty do produkcji, uzbrojenie zasobów pracy w ziemię oraz poziom intensywności produkcji rolniczej. Ponadto, na podstawie metody deterministycznej dokonano oceny zmian wydajności pracy w rolnictwie UE oraz w Polsce. Badania wykazały, że w latach 2005-2016 wydajność pracy mierzona wartością dodaną brutto zwiększała się w UE-28 średniorocznie o 2,13%, w UE-15 tylko 0,98%, a w UE-13 znacznie szybciej, tj. o 3,45%. Oznacza to, że w rolnictwie UE zachodzą procesy konwergencji wydajności pracy. W świetle analizy deterministycznej głównymi czynnikami wzrostu wydajności pracy w rolnictwie UE-28 i w Polsce były wzrost intensywności produkcji oraz wzrost uzbrojenia pracy w zasoby ziemi. Korzystny kierunek przemian wydajności pracy osłabiała malejąca efektywność wytwarzania mierzona produktywnością nakładów oraz udziałem wartości dodanej w przychodach.
Abstract	The main aim of the work was to present the changes observed in the labour productivity in EU agriculture in years 2005-2016. The author proposed also the methodical decomposition of the labor productivity ratio in agriculture. Seven factors (ratios) have been taken into account in three models of labor productivity decomposition. These factors are: inputs productivity, land productivity, value added index, production taxation, production subsidies, equipment employed in agricultural land and the level of agricultural production intensity. The use of the deterministic method allowed to analyse the changes in labour productivity from the perspectives both in the EU agriculture (EU-28) and in the Polish agriculture. Performed studies seems to prove that in the years 2005-2016 the labor productivity measured by gross value added increased in case of EU-28 by average 2.13% and in the case of EU-15 only by 0.98%. At the same time, higher increase was observed in the case of EU-13 which equal to 3.45%. It may suggest that can be observe the ongoing process of the labor productivity convergence in EU agriculture. In the light of deterministic analysis, it was possible to specify the main factors contributing to the increase in labor productivity in agriculture in the EU-28 and in Poland, which are the increase in production intensity and the increase in agricultural land/labour relation. However, it should be also noted that the favorable direction of changes in labour productivity was weakened by the decreasing efficiency of production measured by the inputs productivity and the share of value added in revenues.

Title	AN ASSESSMENT OF HARBERGER-LAURSEN-METZLER EFFEKT IN AGRIBUSINESS SECTOR IN POLAND
Słowa kluczowe	terms of trade, rachunek obrotów bieżących, wektorowa autoregresja, polski sektor rolno-żywnościowy
Key words	terms of trade, current account, vector autoregression, Polish agro-food sector
Abstrakt	W opracowaniu podjęto problem oszacowania efektu Harbergera-Laursena-Metzlera w odniesieniu do polskiego sektora rolno-żywnościowego. Analiza obejmuje lata 2002-2017. W badaniu zastosowano metodykę wektorowej autoregresji (VAR). Wyniki studium ukazały, że trwałe pogorszenie terms of trade wpływa na poprawę bilansu handlowego polskiego sektora rolno-żywnościowego. Natomiast nie zidentyfikowano skutków krótkookresowych szoków terms of trade. Dodatkowo, badanie umożliwiło zidentyfikowanie wartości dodanej brutto (GVA) jako najbardziej egzogenicznej składowej systemu VAR. Najbardziej endogenicznym czynnikiem w modelu okazało się saldo obrotów bieżących. Długookresowe zmiany terms of trade są czynnikiem bardziej egzogenicznym niż saldo obrotów bieżących.
Abstract	The aim of the study was to asses the Harberger-Laursen-Metzler effect in Polish agro-food sector. The analysis covers period of 2002-2017. There was applied the vector autoregression (VAR) methodology. The outcome of the research revealed that permanent deterioration in terms of trade contributed to the current account of Polish agribusiness sector improvement. The temporary effect of terms of trade shocks was not indentified. Additionally, the research enabled recognition of gross value added (GVA) as the most exogenous factor of the VAR system. On the other hand most endogenous factor of the model is the current account. The variable permanent terms of trade is more exogenous factor than the current account.

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.

Tytuł	PROACTIVE PURCHASE BEHAVIOUR AND THEIR RELATIONS IN SIMPLE SATISFACTION MODEL
Title	Proaktywne zachowania zakupowe i ich relacje w prostym modelu satysfakcji
Słowa kluczowe	consumer research, proactive consumer behaviour, satisfaction model, structural equation modelling (SEM)
Key words	badania konsumenckie, proaktywne zachowania zakupowe, model satysfakcji, modelowanie równań strukturalnych (SEM)
Abstrakt	The purpose of the paper was to verify how proactive shopping behaviours, as declared by the respondents, affect the relationship between expectations, perceived quality and customer satisfaction within a simple satisfaction model. The subject of research was supermarket customers. The authors of the article assumed ten proactive shopping behaviours and then built and verified a satisfaction model in the groups of respondents declaring, or not declaring, the given behaviour. The main conclusions resulting from the analysis is that satisfaction with purchases is more determined by the perceived quality in the case of customers who declare frequent purchases of products that improve the standard of living, consistency in purchasing perceived products and rapidity of purchasing decisions.
Abstract	Celem przeprowadzonych badań była chęć weryfikacji czy i w jakim stopniu deklarowane przez respondentów proaktywne zachowania zakupowe wpływają na relacje między oczekiwaniami, postrzeganą jakością a satysfakcją klientów w prostym modelu satysfakcji. Podmiotem badań byli klienci supermarketów. Autorzy artykułu przyjęli dziesięć zachowań, w których może demonstrować się proaktywna postawa zakupowa. Następnie ustalono modele satysfakcji w grupach respondentów deklarujących lub niedeklarujących dane zachowanie. Głównymi wnioskami wynikającym z analiz jest to, że satysfakcja z zakupów w większym stopniu zdeterminowana jest przez postrzeganą jakość w przypadku klientów deklarujących częste kupowanie produktów, które poprawiają poziom życia, konsekwencję w nabywaniu upatrzonych produktów oraz szybkość (niezwłoczność) podejmowanych decyzji zakupowych.

Tytuł	IMPACT OF INTERNATIONALIZATION ON THE CAPITAL STRUCTURE OF COMMERCIAL COMPANIES
Title
Słowa kluczowe	multinational companies, indebtedness, corporate finance, capital structure
Key words
Abstrakt	International enterprises (in this paper, international companies are understood as companies that sell their products and services abroad) are precious for the national economy because, through their experience in international sales, they stimulate the development of other companies in the same industry and their subcontractors. The knowledge that these companies have gained on international markets through the spillover effect spreads on their suppliers, as well as through imitation or cooperation on their competitors. Also, international companies (in the meaning: domestic export companies) are often the first to use new technological solutions and product innovations, which contributes to the modernization of products in the entire business sector. Dynamic and robust international companies usually also build networks with entities from different countries in order to cooperate on development, negotiation, and sales, which also encourages similar activities of their competitors. For all these reasons, national governments should take action to help to export companies, or at least monitor the problems that such entities report. The purpose of the publication is to draw attention to the higher demand for the debt that exists in such enterprises and to discuss the reasons for this. In particular, the purpose of the publication was to verify 2 research hypotheses: H1: Internationalization increases indebtedness of a company measured with the debt to equity ratio, and H2: The scale of internationalization (measured with the share of foreign sales to total sales) is positively related to the level of indebtedness (measured with the debt to equity ratio). For both hypotheses we found no grounds to reject these hypotheses. In the opinion of the authors, the demand for debt from exporters should be monitored, especially in terms of the availability of this form of financing for exporters from the SME sector. The paper used the Arellano-Bond model and data downloaded from the Orbis database for years 2007 – 2017.

Title	Multidimensional Determinants of National Food Security in Azerbaijan: an Application of the ARDL Approach
Słowa kluczowe	food availability, food access, food stability, Azerbaijan
Key words	food availability, food access, food stability, Azerbaijan
Abstrakt	Food intake is a prerequisite for human beings to live a healthy life style. The attainment of food security is crucial and is a prime development priority for all developing countries. The inability to provide reliable evidence of national food security has remained a problem for both policymakers and researchers alike. The present study helps fill this gap by incorporating the multidimensional determinants of food security at the national level in Azerbaijan. The specific objectives of the study are to evaluate the short-term and long-term dynamics of these determinants on food security. The empirical analysis draws from nationally representative time series data over the period 1991 to 2018, taken from FAO and WDI. The ARDL model suggested that food import, exchange rate, inflation, climate change, and urban population growth harm national food security dynamics of Azerbaijan. On the other hand, trade to GDP ratio has a positive impact on food security. Overall results suggest that there is a pressing need to improve its institutional framework if the Azerbaijan government sincerely desires to have sustainable food security, as organizations control all other issues.

Title	Competitiveness of European Union Countries in Foreign Trade in Beef Products
Słowa kluczowe	eksport, import, wołowina, międzynarodowa konkurencyjność
Key words	export, import, beef, international competitiveness
Abstrakt	Głównym celem artykułu jest próba oceny konkurencyjności krajów Unii Europejskiej w handlu zagranicznym produktami wołowymi w 2017 r. w porównaniu z 2005 r. Realizując cel opracowania wykorzystano analizę porównawczą wartości eksportu, importu, sald handlu zagranicznego produktami wołowymi, wskaźnika ujawnionej przewagi komparatywnej RCA, wskaźnika przewag komparatywnych Lafaya oraz wskaźnika Grubela-Llyoda. W 2005 r. i w 2017 r. następujące kraje posiadały przewagę komparatywną w handlu produktami wołowymi: Austria, Francja, Irlandia, Luksemburg oraz Polska, a przewagi komparatywnej nie posiadały: Bułgaria, Cypr, Dania, Finlandia, Grecja, Włochy, Malta, Hiszpania, Szwecja, Portugalia i Wielka Brytania. W 2017 r. większość krajów UE realizowała model handlu wewnątrzgałęziowego. W 2017 r. w porównaniu do 2005 r. niektóre kraje UE zmieniły model realizowanego handlu z międzygałęziowego na wewnątrzgałęziowy lub odwrotnie. W 2017 r. Polska zajmowała piątą pozycję wśród największych eksporterów produktów wołowych w UE, a udział produktów wołowych zaimportowanych do Polski w przywozie produktów wołowych krajów UE był bardzo niski (i wynosił ok. 1%).
Abstract	The main purpose of the article is an attempt to assess the competitiveness of European Union trade in foreign trade in beef products in 2017 compared to 2005. In order to achieve the objective of the study, a comparative analysis (for exports, import value, balance of foreign trade in beef products, the index of revealed comparative advantage of RCA, the comparative advantage of Lafay and the Grubel-Llyod indicator) was used. In 2005 and 2017, the following countries had a comparative advantage in trade in beef products: Austria, France, Ireland, Luxembourg and Poland. Those which did not have a comparative advantage: Bulgaria, Cyprus, Denmark, Finland, Greece, Italy, Malta, Spain, Sweden, Portugal and Great Britain. In 2017, most EU countries implemented the intra-industry trade model. In 2017, compared to 2005, some EU countries changed their trade model from inter-industry to intra-industry or vice versa. In 2017, Poland was fifth among the largest EU exporters of beef products in the EU, and the share of beef products imported to Poland in the import of beef products of EU countries was very low (and amounted to about 1%).

Title	Intra-industry Trade in Agri-food Products between the EU and US
Słowa kluczowe	handel wewnątrzgałęziowy, indeks Grubela-Lloyda, indeks krańcowego handlu wewnątrzgałęziowego, handel wewnątrzgałęziowy poziomy, handel wewnątrzgałęziowy pionowy, produkty rolno-spożywcze, UE, USA
Key words	intra-industry trade, Grubel-Lloyd index, index of marginal intra-industry trade, horizontal intra-industry trade, vertical intra-industry trade, agri-food products, the EU, the US
Abstrakt	Celem artykułu było zbadanie intensywności i określenie typu handlu wewnątrzgałęziowego produktami rolno-spożywczymi UE z USA. Analizę przeprowadzono na podstawie danych pochodzących z bazy Comext-Eurostat, na 6-cyfrowym poziomie klasyfikacji HS w latach 2007-2018. Na podstawie zrealizowanych badań można stwierdzić, że handel produktami rolno-spożywczymi UE z USA rozwija się głównie zgodnie z modelem specjalizacji międzygałęziowej, która w latach 2007-2018 utrwalała się i pogłębiała. Wymianę wewnątrzgałęziową, częściej pionową niż poziomą, obserwowano przede wszystkim w obrotach produktami o wyższym stopniu przetworzenia.
Abstract	The aim of the paper was to examine the intensity and to determine the type of intra-industry trade in agri-food products between the EU and US. The analysis was based on data from the Comext-Eurostat database and it was carried out at the 6-digit level of HS classification in 2007-2018. Based on the conducted research, it can be concluded that trade in agri-food products between the EU and US is developing mainly in accordance with the model of inter-industry specialisation, which in the years 2007-2018 was strengthening and deepening. Intra-industry trade, vertical rather than horizontal, was primarily observed in the exchange of products with a higher degree of processing.
