Tytuł	Wybrane aspekty wykorzystania teorii chaosu do wspierania decyzji finansowych
Title	Selected aspects of the use of chaos theory to support financial decisions
Słowa kluczowe	teoria chaosu, rynki kapitałowe, analiza R/S, wykładnik Hursta, wymiar fraktalny
Key words	chaos theory, capital markets, R/S analysis, Hurst exponent, fractal dimension
Abstrakt	Celem publikacji jest omówienie wybranych aspektów teorii chaosu deterministycznego, oraz prezentacja rezultatów badań dotyczących możliwości wykorzystania narzędzi chaosu deterministycznego (wymiaru fraktalnego, wykładnika Hursta) do wspierania decyzji finansowych inwestorów giełdowych na przykładzie wybranych spółek funkcjonujących na Giełdzie Papierów Wartościowych w Warszawie. Decyzje finansowe dotyczące inwestowania na rynku kapitałowym są na całym świecie przedmiotem licznych badań i analiz. Wykorzystuje się w nich różne metody i narzędzia badawcze. W celu prognozowania decyzji finansowych konstruowane są rozmaite modele, które nigdy nie dają pełnej pewności sukcesu i są obarczone, zwykle ryzykiem inwestycyjnym. Jedną z nowszych koncepcji wspomagania decyzji finansowych jest teoria chaosu deterministycznego. Cechy charakterystyczne, stany nierównowagi oraz mechanizm sprzężenia zwrotnego w wymiarze czasowym, znajdują swój wyraz w opisie za pomocą dynamicznych systemów nieliniowych.
Abstract	The aim of the paper is to discuss selected aspects of the deterministic chaos theory and to present the results of research on the possibility of using deterministic chaos tools (fractal dimension, Hurst exponent) to support financial decisions of stock investors on the example of selected companies operating on the Warsaw Stock Exchange. Financial decisions on investing in the capital market are the subject of numerous studies and analyzes worldwide. Various methods and research tools are used. In order to forecast financial decisions, various models are constructed that never give full assurance of success and are burdened, usually with investment risk. One of the newer concepts of financial decision support is the theory of deterministic chaos. Characteristics, imbalances and feedback mechanisms in the time dimension find their expression in the description using dynamic non-linear systems.

Tytuł	Pozycja konkurencyjna Polski na światowym rynku zagęszczonego soku jabłkowego
Title	Competitive position of Poland on the global market of apple concentrated juice
Słowa kluczowe	eksport zagęszczonego soku jabłkowego, konkurencyjność, pozycja konkurencyjna
Key words	export of apple concentrate juice, competitiveness, competitiveness position
Abstrakt	Celem badań było określenie pozycji konkurencyjnej Polski na rynku zagęszczonego soku jabłkowego w latach 2004–2015. W badaniu wykorzystano: saldo obrotów, udział w światowym eksporcie, wskaźnik ujawnionej przewagi komparatywnej (RCA) oraz indeks relatywnej komparatywnej przewagi eksportu (XRCA). Zastosowane mierniki wykazały, że eksport z Polski był konkurencyjny. Saldo handlu zagęszczonym sokiem jabłkowym w latach 2004–2015 wzrosło. W badanym okresie zwiększył się też udział Polski w światowym eksporcie soku. W latach 2004–2015 Polska miała przeciętną i silną przewagę komparatywną w eksporcie zagęszczonego soku jabłkowego, a Chiny silną. Najsilniejszą przewagę komparatywną w latach 2013–2015 uzyskały Mołdawia i Ukraina.
Abstract	The aim of the study was to establish the competitive position of Poland on the market of apple juice concentrate in the years 2004–20015 and compare it with the position of competitors. The research used the trade balance, share in the word exports, revealed comparative advantage index (RCA) and revealed comparative export advantage index (XRCA). In the analyzed period Poland was the second biggest exporter of apple juice concentrate in the world, preceded only by China. The applied measures showed that export from Poland was competitive. The trade balance of apple juice concentrate from Poland increased in the years 2004–2015. In the analyzed period Poland’s share in international export increased as well. The revealed comparative export advantage index showed that in years 2004–2015 Poland had an average and strong comparative advantage in apple juice concentrate exports, while China’s comparative advantage was strong. The strongest comparative advantage in years 2013–2015 was obtained by Moldova and Ukraine.

Tytuł	INNOVATIVE DEVELOPMENT OF UKRAINE
Title
Słowa kluczowe	innovation, innovative development, strategy, digital economy
Key words
Abstrakt	It is determined that in economic science there is no single approach to the interpretation of the concept of ‘innovation’. It is suggested that taking into account the radical changes that are in the world economy today it is necessary to use the extended concept of innovation, which should be understood as the results of the development transformation, research, ideas and their combination into a radically new or improved technological, economic, social solution, the results of which can be applied in practice. The main indicators that determine the level of innovation development of a country or region and provide an opportunity to determine the impact on economic development are covered. The place of Ukraine in such ratings according to indicators of innovative development in 2017, 2018 and problems that cause their low level are defined. The improvement directions of the innovative development level of the country are defined and the real steps taken by the government of the country to correct the negative trends through the introduction of digital transformation of the country’s economy, the transition from raw material to high-tech production and the basis of innovative IT technologies and communications are shown.

Tytuł	LABOUR PRODUCTIVITY IN THE LIQUID BIOFUELS SECTOR IN SELECTED EUROPEAN UNION COUNTRIES
Title
Słowa kluczowe	biofuels, production, turnover, job creation, labour productivity in the liquid biofuel sector
Key words
Abstrakt	The development of the liquid biofuels sector has been dynamic for more than 10 years, but from the very beginning of this process has been accompanied by a number of controversies as the production and use of liquid biofuels have both positive and negative effects. These consequences primary concern socio-economic and environmental areas. The most important economic benefits are connected with production, turnover and employment in the biofuels industry and the development of agriculture through higher demand on agricultural commodities. The aim of the paper was to quantify labour productivity in the liquid biofuels sector in European Union countries. It is hypothesized that highly developed countries (measured by GDP per capita) have higher labour productivity in the liquid biofuels industry than poorer European Union countries. The second hypothesis states that countries with high liquid biofuel production have higher labour productivity than other countries. The period under research covered the years 2009–2015. The data are mainly from Eurostat, EurObserv’ER consortium and World Bank. This research provides the general conclusion that a high level of economic development is not accompanied by high labour productivity (two types) in the liquid biofuels sector (there is no significant positive correlation). The same applies to the relation between biofuel production volume and labour productivity. The research proves that a high level of GDP per capita or the big scale of biofuel production (and use) is not a determinant of high labour productivity in this sector.

Tytuł	EMPLOYMENT IMPACTS OF RENEWABLE ENERGY IN UE
Title
Słowa kluczowe	renewable energy sources, employment, panel estimation
Key words
Abstrakt	In the world renewable energy sector, including large hydropower, employed 10.3 million people, directly and indirectly, in 2017. This represents an increase of 5.3% over the number reported the previous year. The aim of the executed research is to determine the influence of harvesting renewable energy on the labour market in EU. Eurostat databases provided a source of empirical data concerning the amount of produced energy. The following sectors were considered: solid biofuels, biogas, liquid biofuels, geothermal, hydropower, municipal waste, solar photovoltaic, solar thermal, wind power and heat pumps. The research concerned 28 Member States of the EU between 2009 and 2016. Panel estimation was used as means of empirical indication of relations between the variables. The obtained models are adjusted to the empirical data, the rectified coefficient of determination equalled, depending on the sector, 0.828 (liquid biofuels) to 0.981 (solid biofuels). The analysed models show that throughout the examined period, the solar and wind power sectors were the ones that consumed the larger amount of work. As it was indicated above, these sectors are considered the most innovative and technologically advanced ones and thus, the employment rates seem to decreased in the shorter time.

Tytuł	ECONOMIC EVALUATION OF INVESTMENT ACTIVITY OF AGRICULTURAL ENTERPRISES IN THE UKRAINE
Title
Słowa kluczowe	investment, investment activity, agricultural enterprises
Key words
Abstrakt	The article specifies that intensive development of the economy can be achieved by attracting and effectively using investment resources. Based on the indicator of the level of investment sufficiency, it was established that, in the period under review, the level of investment adequacy in the country is less than the established ‘threshold’ value, which indicates a shortage of investment funds. The study analysed the dynamics of investment attraction in agriculture. It was found that the main source of financing for investment is own funds of enterprises and organizations. However, they are too insufficient to ensure the intensive development of the economy. An analysis of growth dynamics of the total volume of investment in agricultural enterprises per 100 ha of agricultural land and their financial provision was carried out. Research showed that the increase in the value of fixed assets is more intensive than the increase in the inflow of investment in fixed assets, which indicates additional sources of growth in the value of fixed assets. It was noted that the potential sources of investment resources should be the funds of foreign investors, which currently stand at an extremely low growth level. A number of negative factors influencing the process of attracting foreign direct investment were identified. The main current requirements of the Ukraine in the process of integration into the world economic space, is the formation of a mechanism of investment activity, an important component of which is the mechanism of investment provision.

Tytuł	ROLE OF POULTRY INDUSTRY IN PUBLIC FOOD SUPPLY
Title
Słowa kluczowe	livestock, poultry industry, poultry meat, egg, food supplies
Key words
Abstrakt	Within the framework of implementation of overarching national tasks, special attention is paid to the food production and the matter of keeping up with the consumer demand for quality food, which is of national significance. The poultry industry is able to make its fairly considerable contribution into solving the problems of the consumer demand for valuable healthy food products; and to create conditions for the national food security owing to this industry economic growth based on its production potential development and strengthening. The domestic and foreign practice clearly demonstrates that it is possible to provide the population with quality food within a relatively short term, primarily due to the increase of egg and poultry meat production. The poultry industry is not only the most dynamic and fast-growing branch of the livestock farming, but also it has the most intensive production methods. The aim of this article is to determine the influence and the role of the poultry industry on providing the population with food supplies in present-day conditions in the world.

Title
Słowa kluczowe	food security, Global Food Security Index, Sub-Saharan Africa
Key words
Abstrakt	The main purpose of the study is to identify food security problems in Sub-Saharan African countries. Despite progress in increasing food security in the world, it is still one of the most important challenges facing Sub- -Saharan Africa. The research shows that the food security is different across countries. The more favourable situation takes place in South Africa, Botswana, while at the other extreme are countries such as Madagascar, Burundi and Sierra Leone. The economic affordability of food seems to be the most important problem for these countries. So an inclusive growth could be a chance to improve the level of food security.

Tytuł	GLOBAL DIFFERENCES IN LABOUR PRODUCTIVITY IN THE AGRIBUSINESS
Title
Słowa kluczowe	agribusiness, labour productivity, economic growth
Key words
Abstrakt	The purpose of this paper is to assess the global differences in labour productivity in the agribusiness. The relationship between a country’s economic development level (measured as GDP per capita) and labour productivity in the agriculture and across the entire agribusiness was measured in 39 countries around the world (which are entered to the World Input-Output Database and for which the relevant I/O tables were prepared) in 2000 and 2014. The input-output analysis, employed as the main research method, enabled the calculation of value added in the agriculture and elsewhere in the agribusiness. The results suggest the existence of a positive linear association between agribusiness labour productivity and economic development level, as corroborated by previous observations. In turn, two separate groups are noticeable in the relationship between agricultural labour productivity and the level of development of a country. In the first group of countries, agricultural labour productivity grows fast as the economy grows whereas in the second group, the growth rate of labour productivity clearly decreases as the economy grows. This study is a part of the discussion on the global agricultural development model which, on the one hand, calls for increasing the productivity of agricultural labour and, on the other, shows a need to reduce environmental degradation.

Title
Słowa kluczowe	international trade, exports, imports, population size, GDP, inflation rate, the EU, the USA, BRICS countries
Key words
Abstrakt	The aim of this paper is to present changes in the role of EU countries, the USA and BRICS countries in international trade of goods and services and selected macroeconomic determinants of trade exchange in the analysed countries in the years 1960–2015 together with the projection of potential development of the situation until 2070. Investigated macroeconomic trade conditions included population size, GDP, GDP per capita and the inflation rate. Naive forecasting methods were used to estimate selected characteristics, as well as export and import volumes, considering their development trends. The analyses showed that currently, the largest global trade centres, i.e. the EU and the USA, are losing their share in global GDP. Their share in global exports and imports is decreasing to the advantage of BRICS countries. The simulation up to 2070 showed that the trends observed in previous years may be increasing, while the position of the EU and the USA in world trade may be weakening.

Tytuł	INSTAGRAM AS A TOOL FOR PROMOTING SUPERFOOD PRODUCTS
Title
Słowa kluczowe	superfood, instagram, online communication, social selling
Key words
Abstrakt	Social media, Instagram included, are more and more often used by enterprises to promote their own products. Year by year there has been an increase in the rate of the use of the analysed channels of marketing, which seem to be one of the most basic forms of spreading information about their products for enterprises active in the field of superfood products. Superfoods are products containing elements characterised by a wealth of nutritional values, e.g. chia seeds or goji berries. The article presents a short characteristic of social media and defines the eponymous superfood category. The research section of the publication analyses the Instagram activity of three Polish producers of food containing superfood elements, namely Chias – a snack producer, ZmianyZmiany – a producer of plant bars, and PowerWaters – a producer of water with caffeine. The current state of affairs with respect to Instagram profiles of the three discussed brands are studied comprehensively and several applicable recommendations are presented. The research also touches upon the issue of improving customer engagement levels as well as the issue of barter exchange as a way to increase sales and brand awareness in the virtual world.

Title	The production of apple in Poland – environmental, economics and logistics aspects
Słowa kluczowe	jabłka, rynek, produkcja, opłacalność, perspektywy rozwoju
Key words	apples, market, production, profitability, development perspectives
Abstrakt	Celem pracy była ocena warunków środowiskowo-ekonomicznych uprawy jabłek w Polsce, w tym warunków glebowo-klimatycznych, poziomu produkcji i jej opłacalności oraz struktury zagospodarowania na podstawie materiałów źródłowych za pomocą metody opisowej i porównawczej. Polska ze względu na swoje dobre warunki glebowo-klimatyczne jest największym producentem jabłek w Unii Europejskiej i jednym z większych w skali świata. W strukturze zagospodarowania tych owoców dominuje przetwórstwo (produkcja soku zagęszczonego), następnie export i bezpośrednie spożycie. Zwiększenie wartości współczynnika opłacalności produkcji jabłek wymaga stałej optymalizacji warunków uprawy, wprowadzenia koncepcji logistyki do sprawnego zarządzania zaopatrzeniem, produkcją i dystrybucją oraz poszukiwania nowych rynków zbytu i efektywnych sposobów zagospodarowania nadpodaży owoców.
Abstract	The aim of this paper was to assess the environmental and economic conditions of apple cultivation in Poland, including soil and climate conditions, production level and its profitability, the structure of management based on source materials using a descriptive and comparative method. Due to good soil and climatic conditions, Poland is the largest producer of apples in the EU and one of the largest in the world. In the utilization structure of these fruits is dominated by food processing (especially production of concentrated juice), followed by export and direct consumption. Increasing the values of profitability production index, requires optimization of cultivation conditions, introduction of the logistics concept for efficient management of supply, production and distribution as well as searching for new markets and effective ways of managing the oversupply of fruit.

Tytuł	Ewolucja światowego rynku piwa
Title	The Evolution of World Beer Market
Słowa kluczowe	rynek, piwo, chmiel, globalizacja
Key words	market, beer, hop, globalisation
Abstrakt	W latach 1980-2016 światowy rynek piwa charakteryzował się wysoką dynamiką rozwoju. Produkcja i obroty handlu zagranicznego znacząco wzrosły. Istotny wpływ miały na to procesy globalizacyjne. Światowa produkcja piwa jest zdominowana przez duże koncerny browarnicze, ale w ostatnich latach ich udział w rynku zmniejszył w związku z rozwojem produkcji w małych browarach. Rosnąca produkcja piwa generuje duży popyt na surowce wytwarzane w działach pierwotnego przetwórstwa żywności (słód, ekstrakt chmielowy, cukier). Na polskim rynku piwa były obserwowane analogiczne tendencje. Duże bezpośrednie inwestycje zagraniczne, koncentracja struktur podmiotowych i w konsekwencji dynamiczny wzrost produkcji i eksportu. Na krajowym rynku także wzrasta produkcji w małych browarach.
Abstract	Over the period of 1980-2016 the world beer market showed a dynamic development. Both the production and foreign trade volumes considerably increased, which largely resulted from globalisation processes. The production of beer in the world is dominated with large brewing companies. However in recent years their share contracted due to expansion of small-scale brewing. Growing production of beer generates demand for raw materials (malt, hops extract, sugar). The world tendencies were mirrored on the Polish market. Large foreign direct investments along with concentration of production triggered a dynamic growth of production and exports. The share of small breweries in Poland has recently been growing as well.

Title	The plunge of Oil Prices in the Global Economy – Main Determinants and Implications. Analysis on the Basis of the Period of 2014-2015
Słowa kluczowe	szoki naftowe, polityka dostosowawcza, równowaga zewnętrzna
Key words	oil shocks, adjustment policy, external balance
Abstrakt	Celem artykułu jest analiza determinant i konsekwencji spadku cen ropy naftowej w okresie 2014/2015. Epizody te są słabiej opisane w literaturze przedmiotu, w porównaniu do okresów wzrostu, zarówno na gruncie badań teoretycznych, jak i empirycznych. Wynika to z mniejszej częstotliwości występowania okresów spadku cen, jak i oczekiwanych w mniejszym stopniu negatywnych konsekwencji. Doświadczenia lat 2014/2015 wykazują, że także okres spadku cen surowca ma negatywne konsekwencje, przede wszystkim dla eksporterów, ale także dla importerów oraz gospodarki globalnej. W artykule wykorzystano zasadniczo dwa obszerne raporty międzynarodowych instytucji: Banku Światowego i Międzynarodowego Funduszu Walutowego oraz dokonano przeglądu literatury światowej. Zwrócono uwagę na dylematy krajów eksporterów z wyborem odpowiedniej polityki dostosowawczej, w tym rolę polityki fiskalnej i kursowej, oraz reformy strukturalne w zarządzaniu powstałą nierównowagą zewnętrzną i fiskalną tej grupy krajów.
Abstract	The aim of the article is to investigate the main determinants and implications of the fall of oil prices during the period of 2014/2015. The episodes of oil prices’ plunge are not presented in the literature, both theoretical and empirical one, as much as the episodes of price increases. The episodes of plunge are not as common in the economy as episodes of increases, and the negative consequences of the former are supposed not to be as severe as these of the latter. On the basis of the experiences of the last oil price plunge one can see the negative consequences can tackle both exporters and importers. The article is based mainly on two broad reports, of IMF and World Bank, and a set of publications. It discusses the problems of adjustment policy, especially fiscal and exchange rate policies, and structural reforms taken by exporting countries in the process of management of external and fiscal imbalances.

Abstrakt	Przedstawiono zmiany w produkcji oraz tendencje w niedoborach/nadwyżkach rynkowych masła i sera na świecie w latach 2001-2017 u największych producentów oraz w Polsce. Nadwyżki rynkowe masła zwiększały się w: Nowej Zelandii, UE i Białorusi, a zmniejszały w Australii i na Ukrainie. Niedobory rosły w Chinach, Meksyku, Iranie i Turcji, a zmniejszały się w Rosji i Kanadzie. Względnie zrównoważona produkcja i spożycie występowały w Indiach, Pakistanie, USA i Brazylii. Na rynku sera nadwyżki rosły w: UE, USA, Nowej Zelandii, Argentynie i Białorusi, a zmniejszały się w Australii i na Ukrainie. Niedobory rosły w: Rosji, Brazylii, Meksyku. W Polsce rosły nadwyżki produkcji masła i sera, co skutkowało rosnącym eksportem, kierowanym głównie do krajów UE. Ceny masła i sera w krajach UE i na rynku światowym charakteryzowały się konwergencją. Na początku badanego okresu ceny masła w UE były o 134% wyższe niż na rynku światowym, a sera o 92,6%, a w 2017 r. różnice te wynosiły odpowiednio: 6% i 0,6%.
Abstract	Changes in production and trends in shortages / market surpluses of butter and cheese in the world and in Poland in 2001-2017 were presented. Market surplus of butter increased in New Zealand, EU and Belarus, and decreased in Australia and Ukraine. Shortages grew in China, Mexico, Iran and Turkey, and decreased in Russia and Canada. Relatively balanced production and consumption occurred in India, Pakistan, the USA and Brazil. On the cheese market, surplus grew in: EU, USA, New Zealand, Argentina and Belarus, and decreased in Australia and Ukraine. The shortages grew in: Russia, Brazil, Mexico. In Poland, there were surpluses in butter and cheese production, which resulted in growing exports, directed mainly to EU countries. Prices of butter and cheese in EU countries and on the world market were characterized by convergence. At the beginning of the analyzed period, butter prices in the EU were 134% higher than on the world market, and cheese prices were higher by 92.6%, and in 2017 these differences were respectively 6% and 0.6%.
