Tytuł	USE OF AGRICULTURAL SERVICES IN EUROPEAN UNION COUNTRIES
Title
Słowa kluczowe	agricultural services, European Union
Key words
Abstrakt	The purpose of this paper is to assess the use of agricultural services in European Union countries in the context of selected features of agriculture. The Ward’s Method was used to isolate six typological clusters of European Union countries. It may be noticed that clusters with a high levels of fixed capital consumption and total intermediate consumption are characterized by a higher use of services than other clusters. The absence of a noticeable relation between the share of crop output in the structure of agricultural output, or between the labour input and the use of agricultural services can be explained by differences in natural conditions, traditional farming models and preferences in choosing between developing the farm’s own machinery or using services.

Tytuł	BEHAVIOURAL FINANCE IN AGRIBUSINESS – THE BIRTH OF A CONCEPT
Title
Słowa kluczowe	homo oeconomicus, rationality, agriculture, speculative motif
Key words
Abstrakt	Up until now, a model approach has constituted the core of mainstream economics with regard to the decision maker and decision-making conditions. The financial (and economic) crises appearing with increased frequency and numerous market anomalies, although considered predictable by economists and being only a residual component of econometric models, are related to the growing financialization of the economy and an existing asymmetry of information in the absence of full decision-maker rationality. The importance of the psychological characteristics of individuals, their knowledge, the level of trust and priorities, recognized more and more commonly in economic practice, make it necessary to conduct research to identify ‘difficult quantifiable’ characteristics of decision-makers, including their purely economic considerations. (as a supplement to previous economic considerations, including the inclusion of new variables to econometric models that have been in operation for years). The aim of the study was to systematize the evolution of the homo oeconomicus concept along with an indication of further possible directions in its development. A survey of behavioural finance in relation to agribusiness has also been reviewed, which is a perfect example of the evolution of mainstream economics.

Tytuł	AGRICULTURE MODELLING IN THE EUROPEAN UNION
Title
Słowa kluczowe	agriculture, simulation, models, system
Key words
Abstrakt	Agriculture is an important sector of the national economy. Modelling in agriculture is extensively used to evaluate and simulate the development of this industry. There are two main purposes for the development of agricultural models: to develop a scientific understanding of a particular system and obtain information in order to justify agricultural policy decisions and predict their implications. The purpose of this study is to analyse the models used in agriculture in the European Union (EU). To reach these purposes, the following research tasks were set: (1) to analyse the theoretical aspects of simulation modelling; (2) to explore the key agricultural simulation models employed in the EU. The research found that simulation modelling is often used in agriculture by policy makers. There are eight key models of different complexity which are being used to predict the development of the agricultural sector in the EU.

Tytuł	THE FARM TYPOLOGIES AND ITS PERFORMANCE IN ALBANIA (CASE OF ELBASAN)
Title
Słowa kluczowe	Elbasani region, farm typology, farm performance
Key words
Abstrakt	The aim of this paper is to determine the farm typology in Elbasan region and orient policy maker’s agriculture support scheme. Albania is divided into 12 regions and 61 municipality. Region of Elbasan is one of the intermediate ones4 and consists of 4 districts (district of Elbasan, Gramsh, Librazhd and Peqin). Elbasan ranked third by the availability of agricultural land in the country after Fier and Korca (72,872 ha or 10.4% of the agricultural land area at country level). Despite the size of the agricultural land area, it should be considered that a good part of it lies in hilly and mountainous part especially in Librazhd and Gramsh districts. Besides construction and development services, there is observed a growing trend of agricultural activity especially in terms of olive and vegetables cultivation in open field and greenhouses. In this region operate about 32,439 farms. The average farm family size is 4.9 persons, while the national average farm size is 4.5 persons (MAFCP, 2012). The farm typology was determined using nine indicators. Based on these indicators are identified the following type of cluster/typology for Elbasani district: poly-culture for market; livestock; leisure farms; fruit trees; arable crop farm; self-sufficiency. The farm performance was determined using factors productivity which reveals that farms that belong to the poly-culture for market, livestock and self-sufficient clusters are performing better than other clusters.

Tytuł	EXCHANGE OF INFORMATION AND EDUCATION IN COOPERATION BETWEEN AGRICULTURAL HOLDINGS MAINTAINING CONSERVATIVE BREED ANIMALS
Title
Słowa kluczowe	cooperation goals, knowledge exchange and education, livestock conservative breeds, principal component analysis (PCA)
Key words
Abstrakt	The development by means of cooperation, an exchange of knowledge and education is of crucial importance in the contemporary knowledge-based economy. The goal of the study was to determine important goals in cooperation with regard to the scope of knowledge and education of agricultural holdings maintaining conservative breed animals in the region of fragmented agriculture (South-Eastern Poland). The studied entities contribute to an increased biodiversity and maintenance of small agricultural holdings. The conditions of cooperation basing on an exchange of knowledge and education are laid down based on the results of a questionnaire study conducted among 145 agricultural holdings and principal component analyses (PCA). The evaluation of the exchange of knowledge and education varied within the industry. The highest degree of approval for the exchange of knowledge and education was among breeders of pigs and cows, the lowest among sheep breeders. It was demonstrated that participation in fairs and trainings improved the evaluation of analysed cooperation.

Tytuł	THE PHENOMENON OF LAND ABANDONMENT IN THE OPINIONS OF AGRICULTURAL ADVISERS (EXAMPLE OF PODLASKIE VOIVODESHIP)
Title
Słowa kluczowe	land abandonment, land use, agriculture, Podlaskie Voivodeship
Key words
Abstrakt	The phenomenon of abandoning agricultural land is the same as discontinuing the agricultural use of certain agricultural land, the causes of which should be sought in environmental, economic and social factors. In the Podlaskie Voivodeship, agriculture plays a key role in economic life due to the significant number of lands classified as agricultural and century-old tradition of agriculture. The research assessed the existence of threats that could cause the problem of abandonment of agricultural land in the region and indicated the complexity of the land abandonment phenomenon. The study is based on opinions of advisers from the regional Agricultural Extension Service Centre. The results indicated that the process of ceasing to use agricultural land is the result of many factors that mutually influence and strengthen each other.

Tytuł	AGRICULTURAL PRODUCTIVITY IN POLAND IN THE CONTEXT OF STRUCTURAL CHANGES IN THE SECTOR IN 2002–2016
Title
Słowa kluczowe	agriculture, production factors, productivity of land and labour
Key words
Abstrakt	This paper attempts to analyse the changes in labour and land productivity in agriculture in Poland resulting from changes to the production structures in this sector, particularly changes in the relationships between production factors, i.e. land, labour and capital. The analysis covered the years 2002–2016. It was found that this period saw important changes in agriculture expressed in the concentration of agrarian structure and the progressive substitution of land and labour by capital, which was reflected in the increase of work technical equipment and the rate of technical progress. There was also a progressive outflow of some of the labour resources from agriculture. A positive correlation between the productivity of land and labour and the said structural changes in agriculture was found.

Tytuł	WOMEN’S LABOUR MARKET ACTIVITY IN THE AGRICULTURE SECTOR IN POLAND AND EUROPEAN UNION IN 2016
Title
Słowa kluczowe	labour market, female employment, cluster analysis, k-mean method
Key words
Abstrakt	The European authorities pay particular attention to agriculture and employees in this sector. Women represent more than 33% of this group in the European Union. A significant number of actions are targeted at women from rural areas, having regard to the mentioned issues and specific situation of women in the labour market. Therefore, it requires in-depth analyses. The main aim of the presented study is to assess the diversity of the situation of women working in agriculture across the EU. The quantitative analysis allows to indicate similarities and differences among EU states in the current structure of women’s employment in this sector. In the analysis, the k-mean method is applied with the Labour Force Survey data from the year 2016. The study refers to 28 EU states and a group of women aged 20–64. The obtained results indicated that we have a large proportion of self-employees in agriculture. However, we observe a larger percentage of those who create jobs for others states that are better economically developed. This analysis confirms the findings that the Polish structure of female employment is closer to those in the Mediterranean countries. Poland is assigned to one cluster with Greece. This group is distinguished by several factors. Firstly, it contains a high proportion of people employed in agriculture with a relatively small share of part-timers. Secondly, it is a very high rate of self-employed with a very low proportion of those who create jobs for others.

Tytuł	THE ASSESSMENT OF EXPORT POTENTIAL OF AGRICULTURAL AND FOOD PRODUCTS IN THE VISEGRAD GROUP COUNTRIES IN THE YEARS 2005–2017
Title
Słowa kluczowe	foreign trade, agri-food industry, the Visegrad Group
Key words
Abstrakt	The foreign trade in agricultural and food products is a significant reflection of an economic situation occurring in the current functioning of agriculture, food industry and its individual trades in a given country. It is worth considering how the export of Polish agricultural and food products may be compared with the Vise grad Group countries in this area. The article deals with an attempt to assess the export potential of agricultural and food products in the Visegrad Group countries in the years 2005–2017 using a modified index for an assessment of a level of competitiveness in a foreign trade, that is the Revealed Comparative Advantage Index – RCA – by Balassa. The results of the study prove that the export of agricultural and food products in the Visegrad Group countries is vulnerable to economic trends, there is a significant degree of competitiveness regarding export of the food products of animal origin in these countries, and the greatest level of competitiveness of the foreign trade in the food products of plant origin regarding cereals, and the trade in fruit and vegetables is less and less important.

Tytuł	DELIVERING CONSUMER VALUES BY CONSUMER FOOD COOPERATIVES – A CASE OF TWO TYPES OF COOPS FROM POLAND
Title
Słowa kluczowe	consumer food cooperative, utilitarian values, hedonic values, environmental values, participatory cooperative, supermarket cooperative, Poland
Key words
Abstrakt	Consumer choice of a particular type of retail outlet greatly depends on the consumer values that the outlet provides. The aim of this research was to address specific consumer values created by consumer food cooperatives in general, and in addition to examine the difference in the consumer values provided by two major types of such coops in Poland. It is argued that consumer food cooperatives provide customers with unique blend of values, different from those of consumer cooperatives in general due to their close bond with agriculture and environment. Such coops could deliver their customers not only economic or hedonic values but also an additional environmental ones. The environmental values are prevailing in participatory type of coop, while the supermarket type can deliver better the economic values.

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.

Tytuł	Nierówności i ubóstwo ekonomiczne na obszarach wiejskich w Polsce
Title	INEQUALITY AND ECONOMIC POVERTY IN RURAL AREAS OF POLAND
Słowa kluczowe	dochód, nierówności dochodowe, ubóstwo, obszary wiejskie
Key words	income, income inequality, poverty, rural areas
Abstrakt	Celem badań było przedstawienie problemów zagadnienia nierówności i ubóstwa ekonomicznego na obszarach wiejskich w Polsce w latach 2010-2016. Przyjęto hipotezę badawczą zakładającą, iż wysoki poziom nierówności dochodowych prowadzi do wysokiego poziomu ubóstwa relatywnego. Wyniki badań pokazały, iż pomiędzy nierównościami dochodowymi mierzonymi współczynnikiem Giniego a ubóstwem relatywnym na obszarach wiejskich istnieje silna dodatnia zależność. Nie zaobserwowano natomiast żadnego związku pomiędzy zmiennymi dla grupy zawodowej rolników. Można zatem przyjąć, że wzrost nierówności dochodowych na obszarach wiejskich powoduje wzrost ubóstwa relatywnego, ale zależność ta nie dotyczyła ludności, której głównym źródłem utrzymania było gospodarstwo rolne.
Abstract	The aim of the paper was to present the level of disparities and economic poverty in rural areas of Poland in the period 2010-2016. The adopted research assumption was that a high level of income inequality led to a high level of relative poverty. The research was based on the analysis and synthesis of literature and secondary statistical data from the Central Statistical Office. In the theoretical part, the author presented an overview of inequality and poverty definitions. The research part used descriptive statistics and correlation analysis. The obtained results demonstrate that there is a strong positive correlation between income inequality measured using the Gini index and relative poverty in rural areas. No correlation between variables for the professional group of farmers was observed. It can be thus assumed that an increase in income inequality in rural areas leads to an increase in relative poverty, however this correlation does not apply to households, where the main source of income is agriculture.

Title	THE ROLE OF LARGEAGRICULTURAL FARMS IN THE GROWTH OF THE PRODUCTIVITY OF POLISH AGRICULTURE IN THE BACKGROUND OF THE SITUATION IN OTHER SELECTED COUNTRIES OF THE EUROPEAN UNION
Słowa kluczowe	produktywność pracy w rolnictwie, gospodarstwa rolnicze, struktura gospodarstw
Key words	labor productivity in agriculture, farms, farm structure
Abstrakt	W opracowaniu skoncentrowano się na analizie produktywności pracy w rolnictwie polskim w latach 2005 i 2016 w porównaniu do wybranych krajów UE-15 (grupa 1.) i niektórych krajów, które przystąpiły do UE po 2004 roku (grupa 2.). W grupie 1. uwzględniono Austrię, Belgię, Danię, Holandię i Niemcy, natomiast w grupie 2. Czechy, Słowację, Litwę, Łotwę i Węgry. Przy wyborze krajów do badań kierowano się kryterium położenia w tej samej strefie klimatycznej. W analizie szczególnie uwzględniono rolę gospodarstw dużych, których wielkość przyjęto umownie na poziomie 30 ha UR. Celem badań było określenie wpływu gospodarstw dużych na poziom produktywności pracy w gospodarstwach ogółem oraz określenie możliwości zmniejszenia różnic między produktywnością pracy w polskich dużych gospodarstwach w stosunku do analogicznych gospodarstw w krajach UE-15. Stwierdzono w obydwu grupach krajów spadek liczby gospodarstw i zwiększenie produktywności pracy w rolnictwie ogółem i w badanych klasach gospodarstwach dużych. W krajach grupy 2. tempo wzrostu produktywności pracy było wyższe niż w grupie 1. jednak w niewielkim stopniu zmniejszyły się występujące różnice. Produktywność pracy w rolnictwie krajów grupy 1. była istotnie wyższa niż w grupie 2. Wzrost liczby i udziału gospodarstw dużych w strukturze gospodarstw był dodatnio skorelowany z produktywnością pracy w rolnictwie.
Abstract	The study focuses on the analysis of labor productivity in Polish agriculture in 2005 and 2016 in comparison to selected EU-15 countries (group 1) and some countries that joined the EU after 2004. In group 1, Austria, Belgium, Denmark, the Netherlands and Germany are included, while in group 2 - the Czech Republic, Slovakia, Lithuania, Latvia and Hungary. The analysis particularly considers the role of large farms, the size of which was contractually agreed at 30 ha of UAA. The aim of the study was to determine the impact of large farms on the level of labor productivity in total farms and to determine the possibility of reducing the differences between labor productivity in Polish large farms in relation to analogous farms in EU-15 countries, and determining whether changes occurring in Poland differ from those occurring in large farms in other post-socialist countries. In both groups of countries there was a decrease in the number of farms and an increase in labor productivity in agriculture in general and in surveyed classes in large farms. In the countries of group 2. the rate of labor productivity growth was higher than in group 1. However, it slightly reduced the differences. Labor productivity in agriculture in the countries of Group 1 was significantly higher than in Group 2. The increase in the number and share of large farms in the structure of farms was positively correlated with labor productivity in agriculture.

Słowa kluczowe	scalenie gruntów, rolnictwo, AHP
Key words	land consolidation, agriculture, AHP
Abstrakt	Artykuł podejmuje problem merytorycznego wsparcia w procesie zapobieżenia powstawaniu wadliwej struktury obszarowej gospodarstw rolnych. Zachodzące w ciągu dziesięcioleci zmiany struktury obszarowej i własnościowej gruntów użytkowanych rolniczo, spowodowały ich nadmierne rozdrobnienie, które utrudnia prawidłowe i wydajne gospodarowanie. Na przykładzie gminy Jasionówka (woj. podlaskie, powiat moniecki), zaproponowano wykorzystanie procedury analitycznej hierarchizacji (AHP) jako możliwości ustalenia kolejności przeprowadzenia scaleń w poszczególnych obrębach ewidencyjnych badanej gminy. Pozwala to na racjonalne wykorzystanie ograniczonych środków finansowych przy realizacji kosztownych prac scalenia i wymiany gruntów.
Abstract	The paper examines the issue of scientific support to prevent the faulty structures of farms under the consolidation process. Taking place over decades, changes in the structure and ownership of land utilized for agricultural purposes, resulted in excessive disaggregation, which obstructs proper and efficient management. The author, using an example of the Jasionówka commune (province Podlaskie, district Monki), proposes the use of analytic hierarchy process (AHP) as an opportunity to determine the proper order to carry out consolidation in the respective cadastral district. This allows for a rational use of limited financial resources when carrying out costly consolidation and an exchange of agricultural plots. The analysis was performed taking into account the relevant factors characterizing the area.

Słowa kluczowe	dochód, ziemia rolnicza, rynek prywatny, dzierżawa, zmiany
Key words	income, agricultural land, lease, changes
Abstrakt	W ostatnich latach w Polsce rosną ceny ziemi rolniczej, a maleje jej podaż na rynku prywatnym. Sprzyja to rozwojowi zjawiska dzierżawy, która w wielu krajach europejskich jest podstawą prowadzenia działalności rolniczej. Celem opracowania jest charakterystyka dochodów otrzymywanych przez gospodarstwa indywidualne w Polsce z dzierżawy ziemi użytkowanej rolniczo i zmian dochodów w latach 2005-2016. Podstawę analiz stanowiły jednostkowe dane empiryczne, dane z badań sondażowych przeprowadzanych corocznie przez GUS, a ich uzupełnieniem były dane IERiGŻ-PIB, ANR (obecnie KOWR) i opracowania wtórne GUS. W wyniku badań stwierdzono, że dochody z dzierżaw prywatnych uległy podwojeniu w latach 2005-2016 i stanowiły ważny składnik dochodów korzystających z nich rodzin, ale z deklaracji badanych wynika, że miały one niewielką skalę (przeciętnie 0,3% gospodarstw indywidualnych). Grunty rolne były wydzierżawiane przez małe gospodarstwa, których głównym źródłem utrzymania była praca najemna, czasem za granicą, a kierownicy byli starsi niż przeciętnie. Często sytuacja rodzinna była nieuregulowana (np. starszy rodzic z dorosłym, ale jeszcze samotnym dzieckiem, które jeszcze ostatecznie nie zdecydowało o swej przeszłości), a okresowe wydzierżawienie gruntów pozwalało na podjęcie decyzji o ewentualnej sprzedaży gospodarstwa w późniejszym czasie.
Abstract	In last years, the prices of agricultural land in Poland have been rising, and the supply on the private market is decreasing. This favors the development of the lease phenomenon, which in many European countries is the basis for conducting agricultural activity.The purpose of the article was to characterize the income received by individual farms in Poland, from the lease of agriculture land and their changes in the years 2005-2016. The analysis was based of polls unitary empirical data, carried out annually by the Central Statistical Office, and supplemented by data of Institute of Agricultural Economics (IERiGŻ-PIB), Agricultural Property Agency (currently KOWR) and secondary studies of the Central Statistical Office. As a result of the research, it was found that revenues from private leases doubled in 2005-2016 and constitute an important component of revenues for families using them, but the respondents’ declarations show that they are small (on average 0.3% of individual farms). This is small farms, whose main source of income is wage labor, sometimes abroad, and managers are older than average. Often the family situation is unregulated (eg. an elderly parent with an adult but has not yet decided his past), and a periodic land lease allows for a decision on the possible sale of the farm at a later time.

Title	The Position of the Food Industry in Poland’s Food Chain at the Turn of the 20th to the 21st Century
Słowa kluczowe	rynek, przemysł spożywczy, przetwórstwo żywności, rolnictwo, handel, konsument
Key words	market, food industry, food processing, agriculture, trade, consumer
Abstrakt	Przemysł spożywczy jest jednym z głównych ogniw (członów) gospodarki żywnościowej. Jest on największym odbiorcą nieprzetworzonych surowców rolnych, a zarazem głównym dostawcą żywności do sfery handlu (hurtowego i detalicznego). Znaczenie przemysłu spożywczego wzrasta też z tego powodu, że firmy przetwórcze często integrują podmioty biorące udział w procesie produkcji żywności od przysłowiowego pola do stołu. Sprzyja temu wzrost towarowości polskiego rolnictwa oraz rosnący popyt na żywność wysoko przetworzoną. W ostatnich latach przewagę w relacjach handlowych zyskały duże sieci handlowe (głównie z kapitałem zagranicznym), które często narzucają warunki sprzedaży dostawcom żywności (firmom spożywczym, producentom rolnym).
Abstract	The food industry is one of the main elements of the food economy. It is the biggest consumer of raw agricultural materials, and at the same time a primary input into the wholesale trade and retail market. The significance of the food industry is also growing, due to the fact that processing plants often integrate the entities that participate in food manufacturing processes, from the proverbial “field to table.” The high quality of Polish agriculture and the increasing demand for highly-processes foods is adding to the growth of the industry. In recent years, large retail chains have gained an advantage in trade relations (mainly with foreign capital). They often impose conditions for the sale of food suppliers (food companies and agricultural producers).

Słowa kluczowe	agricultural economics, emissions, classification, cluster analysis, k-means, hdbscan
Key words	agricultural economics, emissions, classification, cluster analysis, k-means, hdbscan
Abstrakt	Agricultural emissions represent greenhouse gas emissions from crop and livestock production. There are various estimates on agricultural emissions, however on average about 14 to 25 percent of total global emissions comes from agriculture. The main goal of this paper was to present distribution of agricultural emissions among OECD countries with the help of clustering analysis. Clustering analysis is one of the tools used in the field of exploratory data mining. Two methods were used in the analysis: K-means and HDBSCAN algorithms. Both techniques are part of unsupervised learning tasks, which group data into multiple clusters. Finally, an appraisal of obtained classifications was performed.

Title	The Taxation of Agriculture in the European Union Countries
Słowa kluczowe	tax, taxation of agriculture, agricultural tax
Key words	tax, taxation of agriculture, agricultural tax
Abstrakt	The paper sets out the key principles for taxation of agriculture in selected European Union countries. The theoretical foundations of tax systems in the context of their functions and features specified as desirable in the literature are discussed. EU agricultural taxation systems are presented in reference to optimisation and tax competitiveness. Some shared features of these agricultural taxation systems were pointed out and their division in two basic models (the British model and the continental model), which was presented taking as example the countries in which these models operate. Taxation of income derived from agricultural business activity is a natural direction of changes in tax systems. The tax policy implemented in the European Union countries in relation to agriculture make use of the principle of tax justice to the highest possible extent. The diversity of the tax rules and structures applied in the EU makes it possible to tax agricultural income without limiting the development potential of agricultural enterprises (farms), and often stimulates them. The form of individual tax systems results from numerous economic, social and political circumstances. Special tax treatment of agriculture is expressed through tax construction elements, e.g. right to deduct the value of generated loss or investment expenditure from taxable income.
