Title | The Determinants of Fish Catch: A Quantile Regression Approach |
Słowa kluczowe | quantile regression, fishers, catch |
Key words | quantile regression, fishers, catch |
Abstrakt | The goal of this study is to use quantile regression (QR) to find predictors of fishers’ catch and compare it with OLS regression. The heterogeneous association across the different quantiles of the catch distribution was investigated using QR analysis. The findings reveal that the effect changes depending on where a fisher is in the catch distribution. In the OLS, there are several non-significant predictors that appear to be significant in quantile regression. By OLS regression, demographic variables have little effect on fishers’ catch; but, in quantile regression, marital status, fishing hours, and use of motorized boats appeared to have a relatively high impact at the top of the distribution. |

Title | Consumers’ Awareness on Organic Food: Case of Urban Sri Lanka |
Słowa kluczowe | consumers’ awareness, organic food, regression analysis, urban consumer, Sri Lanka |
Key words | consumers’ awareness, organic food, regression analysis, urban consumer, Sri Lanka |
Abstrakt | The organic food market is rapidly expanding all over the world with the recent rise of concern in food safety and environmental protection. Thus, examining information about consumers’ awareness on organic food is one of the inspiring areas for producers and marketers to capture a greater market share successfully. Therefore, this study aimed at analyzing the consumer awareness towards organic food products while addressing socio-demographic factors affecting consumer awareness on organic food, knowledge of consumers about organic food, and their purchasing pattern. A sample of 600 consumers was selected from the main cities of six urban districts in Sri Lanka for the study. Data were collected via a consumer survey using a pre-tested questionnaire, from November 2018 to May 2019. The data analysis was carried out using frequencies, percentages, and multiple linear regression analysis. According to the results, the majority of the respondents were married females. The results revealed that Sri Lankan consumers have a better awareness on organic food. The results of the regression analysis highlighted that the consumers’ awareness is significantly affected by factors such as gender, marital status, education, and monthly income. Although most respondents have a good level of awareness on organic food, their buying trend is at a lower level. The findings of the study play an important role in promoting the organic food market and are essential for food marketing planners, researchers, and policymakers to enhance the organic food industry in the country in the future. |

Title | Poverty and its Alleviating Strategies among Rural Farming Households in Benue State, Nigeria |
Słowa kluczowe | poverty, alleviating strategies, rural, farming household, Nigeria |
Key words | poverty, alleviating strategies, rural, farming household, Nigeria |
Abstrakt | The study analysed rural farming households’ poverty status and alleviating strategies in Benue State, Nigeria. The specific objectives of the study were to: describes the rural household heads’ socio-economic characteristics; determine the poverty status of the respondents and its determinants; and identify poverty alleviating strategies of the respondents. Data for the study was collected from 420 respondents selected using a multi-stage sampling technique. Data collected were analysed using descriptive statistics, the Foster-Greer-Thorbecke poverty measurement index, and the Binary Logistic regression model. The findings of the study revealed a very high incidence of poverty (70%), having a gap of 0.34, and severity of 0.17. Poverty in the area is positively associated with the age of the household head and household size, while gender, educational level, off-farm activity, membership of a group, farm size, and land ownership are negatively associated with poverty. The common poverty alleviation strategies identified were agricultural wage labour (48.6%), rental services (45.0%), and transportation business (36.7%). Therefore, it was recommended that the government and other stakeholders should initiate sustainable social protection schemes that can assist rural residents in alleviating poverty until their condition improves. |

Title | |
Słowa kluczowe | excise duties, direct employment, V4, the brewing industry |
Key words | |
Abstrakt | The consumption of beer can be considered a cultural element of many European countries. Therefore, it rep_x0002_resents a great contribution to Central European economies mainly in terms of employment, value-added or taxes and duties. Since beer has a plentiful history and permanent popularity, the most powerful global multi_x0002_nationals gradually took over the global market over the last few decades. Therefore, globalization highly af_x0002_fected the structure of the brewing industry that caused the homogenization of products. The aforementioned and also other factors have led to the increase in the establishment of local craft breweries which produce the beloved beverage characterised by traditional recipe and uniqueness. Hence, in this article, we are focus_x0002_ing on the selected macroeconomic indicators like employment or excise duties generated by breweries in Poland, Slovakia, Hungary, and the Czech Republic. Since there is no separate economic data available on industrial and craft beer yet, we focused on the economic impacts of the brewing industry in general, during the period 2010–2019. In the first part of the results, we provide the rate of excise duty on beer as opposed to other alcoholic beverages and in the second part, we focus on direct employment in the industry. The last part focuses on the relation between these two variables by using regression analysis. |

Tytuł | Factors determining the tendency of rural households in Central Pomerania to save – PILOT study results |
Title | Czynniki determinujące skłonność wiejskich gospodarstw domowych Pomorza Środkowego do oszczędzania - wyniki badania pilotażowego |
Słowa kluczowe | rural household, propensity to save, income, Central Pomerania, Poland. |
Key words | wiejskie gospodarstwo domowe, skłonność do oszczędzania, dochód, Pomorze Środkowe, Polska. |
Abstrakt | The aim of this research is to identify factors affecting the propensity of rural households to save, on the example of 100 entities in Central Pomerania, based on pilot studies (direct questionnaire technique) using the logistic regression model. The study assumes that the dependent variable is the occurrence of savings in the household in 2018. The selection of independent variables for the logistic regression model was made on the basis of literature studies. The results of the analysis confirmed that statistically significant parameters for the variables were: average monthly net income per one person in the household, diversification of the income sources and the share of expenses on food and non-alcoholic beverages in total household consumption expenditure. The first two parameters increase the probability of saving by rural households of Central Pomerania. The last of these parameters reduces the chance of deferring consumption through savings. |
Abstract | Celem badań jest identyfikacja czynników wpływających na skłonność do oszczędzania wiejskich gospodarstw domowych na przykładzie 100 podmiotów na terenie Pomorza Środkowego, w oparciu o wykonane badania pilotażowe (technika ankiety bezpośredniej), przy zastosowaniu modelu regresji logistycznej. W badaniu przyjęto, iż zmienną zależną jest występowanie oszczędności w gospodarstwie domowym w 2018 roku. Doboru zmiennych niezależnych do budowy modelu regresji logistycznej dokonano na podstawie przeprowadzonych studiów literaturowych. Wyniki analiz potwierdziły, iż statystycznie istotnymi parametrami przy zmiennych okazały się: przeciętny miesięczny dochód netto na jedną osobę w gospodarstwie domowym, dywersyfikacja źródeł utrzymania oraz udział wydatków na żywność i napoje bezalkoholowe w wydatkach konsumpcyjnych ogółem gospodarstwa domowego. Dwa pierwsze parametry zwiększają prawdopodobieństwo oszczędzania przez wiejskie gospodarstw domowe Pomorza Środkowego. Ostatni z wymienionych parametrów zmniejsza szansę na odroczenie konsumpcji w czasie w drodze oszczędności. |

Title | INDEBTEDNESS OF FARMERS IN POLAND IN LIGHT OF STRUCTURAL CHANGES AND ECONOMIC FLUCTUATIONS IN AGRICULTURE |
Słowa kluczowe | gospodarstwa rolne, kredyt bankowy, koniunktura w rolnictwie, przemiany strukturalne. |
Key words | agricultural holdings, bank credit, economic fluctuations in agriculture, structural changes |
Abstrakt | W artykule dokonano analizy dynamiki oraz struktury zobowiązań kredytowych rolników wobec banków w Polsce w latach 1996-2018. Zadłużenie kredytowe rolników przedstawiono na tle przemian strukturalnych i koniunktury w rolnictwie. Założono, że korzystna koniunktura w rolnictwie stymuluje wzrost zadłużenia rolników w bankach. Podobnie założono, że proces koncentracji struktury agrarnej oraz wzrost technicznego uzbrojenia pracy i technicznego uzbrojenia ziemi będą czynnikami sprzyjającymi wzrostowi zadłużenia kredytowego rolników. Badania nie dały jednoznacznej odpowiedzi na postawione tezy badawcze. Ujawniono dodatnią współzmienność pomiędzy zadłużeniem kredytowym rolników a koniunkturą w rolnictwie, a także procesem substytucji nakładów pracy i ziemi przez nakłady kapitału. Analiza regresji wykazała, że stymulantą zadłużenia kredytowego są nakłady inwestycyjne w rolnictwie, natomiast koncentracja struktury agrarnej oraz poprawa relacji ziemia/praca prowadzi do zmniejszenia przyrostów zadłużenia. |
Abstract | The paper presents an analysis of the dynamics and structure of farmers' credit obligations towards banks in Poland in 1996-2018. The credit debt of farmers is presented against the background of the structural changes and economic fluctuations in agriculture. It was assumed that a favorable economic situation in agriculture stimulates the growth in farmers' indebtedness to banks. Similarly, it was assumed that the process of increasing concentration within the agrarian structure and the increase in the technical equipment of labor and technical equipment of land would be factors conducive to the growth in farmers' credit debt. The research did not give a definite answer to the research thesis. A positive correlation between farmers' credit debt and economic fluctuations in agriculture was revealed, as well as the process of substitution of labor and land inputs by capital expenditures. Regression analysis showed that investment stimulus in agriculture is the stimulus of credit debt, while increased concentration within the agrarian structure and the improvement of the land/work relationship leads to a reduction in debt increases. |

Title | Genetically Modified Crops’ Technology and its Awareness among Smallholder Farmers in Nigeria |
Słowa kluczowe | GMOs, smallholder farmers, awareness for GM crops, Credible seed sources, Agricultural technology |
Key words | GMOs, smallholder farmers, awareness for GM crops, Credible seed sources, Agricultural technology |
Abstrakt | Genetically Modified (GM) crops are crops modified through genetic engineering to improve their quality. Although safety concerns about genetically modified organisms (GMOs) are still being debated, the food security benefits have led to adoption by many counties. In Nigeria, where most farmers are uneducated and likely unaware of the agricultural technology, the government approved its first biotechnology crop for commercialization in 2018. Level of farmers’ awareness is crucial to acceptance of GM crops, although; this has not been fully explored in the literature. Therefore, this study aimed to assess farmers’ awareness for GM crops and the factors that determine their awareness in Oyo state, Nigeria, using primary data collected in 2018 with the aid of well-structured questionnaires from 242 smallholder farmers. Principal component analysis and Tobit regression model were used for data analysis. Results showed that farmers were aged 43 years with farm size of 3.57 ha, farming experience of 14 years and 11 years of education. Most farmers were male (71.90%), married (67.36%), not members of farmer groups (64.46%) and sourced their seeds from non-credible sources (85.12%). Most farmers (52.07%) had either not heard of or did not know of any benefits/costs of GM crops, hence; were not aware of GM crops. Factors that influenced awareness of GM crops were being a male farmer, years of education and source of seeds. The study concluded that increasing years of education and ensuring use of credible seed sources will increase awareness of the costs and benefits of GM crops among farmers. |

Lichota W. Zastosowanie modeli logitowych do zdiagnozowania zagrożenia bankructwem przedsiębiorstw
Autor | Wojciech Lichota |
Tytuł | Zastosowanie modeli logitowych do zdiagnozowania zagrożenia bankructwem przedsiębiorstw |
Title | THE USE OF LOGISTIC MODELS TO DIAGNOSE THE RISK OF BANKRUPTCY IN ENTERPRISES |
Słowa kluczowe | kondycja finansowa, modele wczesnego ostrzegania, analiza finansowa |
Key words | logistic models, bankruptcy, risk assessment, regression analysis |
Abstrakt | W artykule zostały zaprezentowane wybrane modele regresji logistycznej, które służą do analizy przedsiębiorstw w zakresie zagrożenia bankructwem jak i zmiany w sytuacji finansowej. Jak wynika z literatury z zakresu finansów do oceny kondycji finansowej przedsiębiorstwa należy zastosować odpowiednie metody. Błędna ocena może przynieść przykre konsekwencje dla przedsiębiorstwa, w postaci podjęcia nietrafionych decyzji przez zarządzających, odmowy udzielenia kredytu bankowego lub niepodjęcia współpracy przez dostawców i odbiorców. Celem artykułu była weryfikacja skuteczności predykcji 12 modeli regresji logistycznej, które pozwalają na dokonanie oceny zagrożenia bankructwem przedsiębiorstwa a także zajęcia stanowiska odnośnie przyszłej kondycji finansowej. Próba badawcza wynosiła 40 przedsiębiorstw, w tym 8 przedsiębiorstw, dla których został złożony wniosek o upadłość. Jak wynika z przeprowadzonych badań, poszczególne modele odznaczają się różną sprawnością ogólną, która wyniosła od 54% do 98%. Ponadto wykazano, że wraz ze wzrostem wskaźników analizy finansowej użytych w konstrukcji funkcji nie zwiększa się sprawność poszczególnych modeli. Autor podsumowuje, że w celu uniknięcia ryzyka przeprowadzenia niewiarygodnej oceny kondycji finansowej przedsiębiorstwa, należy zastosować co najmniej kilka modeli logitowych. |
Abstract | The article presents selected logistic regression models that are used to analyze enterprises in terms of their risk of bankruptcy and changes in their financial situation. As it appears from the literature on finance, it is necessary to apply appropriate methods to assess the financial condition of an enterprise. Incorrect assessment may cause unpleasant consequences for the company, in the form of taking wrong decisions by managers, refusal to be granted a bank loan or failure to undertake cooperation with suppliers and customers. The aim of the article was to verify the effectiveness of the prediction of 12 logistic regression models, that allow for the assessment of an enterprise’s bankruptcy risk and its future financial condition. The research sample was 40 companies, including 8 enterprises for which a bankruptcy petition had been filed. As results from the conducted research, individual models have different general efficiency, which ranged from 54% to 98%. In addition, it was seen that the efficiency of particular models does not increase with an increase of the financial analysis indicators used in the construction of the function. The author concludes that in order to avoid the risk of making an unreliable assessment of the financial condition of a company, at least 10 logistic models should be used. |

Słowa kluczowe | local food systems, short food supply chains, spatial concentration, marginal localized and restricted activities, nonparametric regression trees |
Key words | działalność marginalna, lokalna i ograniczona, nieparametryczne modele drzew regresji |
Abstrakt | The article analyses spatial concentration of marginal, localized and restricted activities creating local food systems in Poland regarded as short supply chains. Local food systems in Poland can take the forms of direct sale, direct deliveries, agricultural retail as well as marginal, localized and restricted activities. Short food supply chains play crucial role in case of local economy, environment and society. Thus, article rises issue connected with sustainability, alternatives for mass produced and distributed food, spatial diversity of local activities. Empirical part of the article focus on marginal, localized and restricted activities. The first part of the article contains a characteristic of the analyzed activities and their spatial distribution. The second part identifies factors that have the strongest influence on the formation of marginal, localized and restricted activities with the application of nonparametric models of regression trees. It is reported that spatial and environmental factors occur most frequently in the process of recurrent division of the data set and, thus, constitute the strongest determinant of marginal, localized and restricted activities. |
Abstract | W artykule analizie poddano koncentrację przestrzenną podmiotów marginalnych, lokalnych i ograniczonych tworzących lokalne systemy żywnościowe w Polsce i utożsamianych z krótkimi łańcuchami dostaw. Lokalne systemy żywnościowe w Polsce mogą przybierać formy organizacyjno-prawne takie jak: sprzedaż bezpośrednia, dostawy bezpośrednie, rolniczy handel detaliczny oraz działalności marginalną, lokalną i ograniczoną. Krótkie łańcuchy dostaw żywności odgrywają kluczową rolę w lokalnej gospodarce, środowisku i społeczeństwie. W artykule poruszono zatem problematykę związaną ze zrównoważonym rozwojem, alternatywami dla masowo produkowanej i dystrybuowanej żywności, przestrzennym zróżnicowaniem lokalnych podmiotów. Część empiryczna artykułu oparta jest na analizie podmiotów marginalnych, lokalnych i ograniczonych. W pierwszej kolejności dokonano charakterystyki analizowanych podmiotów i ich rozmieszczenia przestrzennego. Następnie, wykorzystując nieparametryczne modele drzew regresji, zidentyfikowano czynniki, które najsilniej wpływają na powstawanie podmiotów marginalnych, lokalnych i ograniczonych. Dostrzeżono, że czynniki przestrzenno- środowiskowe występują najczęściej w procesie rekurencyjnego podziału zbioru danych, a tym samym stanowią najsilniejszą determinantę działalności marginalnej, lokalnej i ograniczonej. |

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. |

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 | 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 | Starzenie się społeczeństwa a wzrost gospodarczy w krajach Unii Europejskiej |
Title | Demographical Ageing and Economic Growth in the UE Countries |
Słowa kluczowe | starzenie się ludności, wzrost gospodarczy, Unia Europejska, modele panelowe |
Key words | demographical ageing, economic growth, European Union, panel models |
Abstrakt | Z uwagi na wciąż pogłębiający się proces demograficznego starzenia się ludności i znaczenie skutków tego procesu dla gospodarki, w artykule poddano analizie relację pomiędzy starzeniem się społeczeństwa krajów Unii Europejskiej a wzrostem gospodarczym. Celem podjętych badań była próba określenia wpływu starzenia się społeczeństwa na dynamikę wzrostu gospodarczego w krajach UE 27. Okres badań obejmował lata 1996-2016, dane pochodziły z bazy Eurostatu oraz Banku Światowego. Na potrzeby badań uwzględniono podział na kraje „starej” Unii i „nowej” Unii. Za miarę wzrostu gospodarczego przyjęto tempo wzrostu PKB, natomiast uwzględnionymi miarami starości demograficznej były stopa starości (odsetek osób w wieku 65+ w populacji) oraz współczynnik sędziwej starości (odsetek osób w wieku 80+ w populacji). Wykorzystano modele panelowe. Stwierdzono, że demograficzne starzenie się społeczeństwa ujemnie koreluje z dynamiką wzrostu gospodarczego. W skonstruowanych modelach panelowych dla krajów „starej” Unii współczynniki regresji odpowiadające stopie starości i współczynnikowi sędziwej starości wynosiły odpowiednio: –0,446 oraz –1,521, podczas gdy dla krajów „nowej” Unii były równe: –0,153 (dla stopy starości) oraz –0,980 (dla współczynnika sędziwej starości). Oznacza to, że negatywny wpływ starzenia się ludności na tempo wzrostu PKB jest silniejszy w krajach „starej” Unii w porównaniu z krajami „nowej” Unii. |
Abstract | Due to the still growing demographic aging process and the significance of this process on the economy, the article analyzes relationship between the demographic aging of the European Union countries and economic growth. The aim of the research was to determine the impact of demographic aging on the rate of economic growth in the EU27. The research period covered the years 2000-2015. Data from the Eurostat and the World Bank databases were used. The study adopted a division into the “old” and “new” EU Member States. The rate of GDP growth was taken as the measure of economic growth, while the measures of demographic aging included the old-age rate (percentage of population aged 65 or over) and the venerable senility rate (share of the population at the age of 80 or more in the general number of population). Panel models were used. It was found that the demographical aging of society negatively correlates with the dynamics of economic growth. In panel models constructed for countries of the "old" Union, regression coefficients for the old-age rate and the venerable senility rate were respectively: –0,446 and –1,521, while for the "new" EU countries were equal to: –0,153 (for the old-age rate) and –0,980 (for the venerable senility rate). This means that the negative impact of demographic aging on the GDP growth rate is more strongly observed in the countries of the "old" Union in comparison with the countries of the "new" Union. |

Słowa kluczowe | gospodarstwo rolne, dzierżawa gruntów, model logitowy |
Key words | farm, land lease, logit model |
Abstrakt | Dzierżawa gruntów rolnych w Polsce stanowi, obok własności, podstawowy tytuł prawny organizowania i prowadzenia gospodarstw rolnych. Możliwość zwiększenia areału prowadzi z założenia do poprawy sytuacji dochodowej rolników. Nie tylko ze względu na rozmiar produkcji i osiągane z niej dochody, ale także ze względu na wysokość otrzymywanych dotacji. Decyzja o dzierżawie gruntów zależy od wielu czynników o charakterze endo- i egzogenicznym. Celem artykułu jest określenie czynników wewnętrznych wpływających na prawdopodobieństwo dzierżawy gruntów przez gospodarstwa rolne w Polsce. Badanie przeprowadzono na podstawie danych rachunkowych uzyskanych w 2015 roku przez gospodarstwa rolne prowadzące rachunkowość rolną na potrzeby polskiego FADN. Określenia czynników wpływających na prawdopodobieństwo dzierżawy gruntów przez gospodarstwa rolne dokonano z wykorzystaniem modelu regresji logistycznej. Wyniki badań wskazują, że prawdopodobieństwo dzierżawy gruntów zwiększa się wraz ze wzrostem: powierzchni użytków rolnych, udziału kapitałów obcych w finansowaniu działalności rolniczej oraz nakładów pracy własnej w gospodarstwie rolnym. Prawdopodobieństwo to wzrasta także wraz z obniżeniem produktywności aktywów trwałych (pomniejszonych o ziemię, uprawy trwałe i kwoty produkcyjne). |
Abstract | The lease of agricultural land in Poland is, apart from ownership, the basic legal title of organizing and running farms. The possibility of increasing the area leads to the improvement of the farmers' income situation. Not only because of the size of production and income from it, but also because of the amount of subsidies received. The decision to lease land depends on a number of endogenous and exogenous factors. The aim of the article was to determine the endogenous factors affecting the likelihood of renting land by agricultural holdings in Poland. The study was conducted on the basis of accountancy data obtained in 2015 by agricultural holdings conducting agricultural accounting for the needs of the Polish FADN. Determining the factors affecting the likelihood of land leased by agricultural holdings in Poland was made using the logistic regression model. The studies carried out prove that the decision to lease the land depends on the resources of the agricultural holding. The presented research results suggest that the probability of renting land increases with the increase in the area of arable land, the share of foreign capital in the financing of agricultural activity and own labor inputs on the farm. This likelihood also increases with decreasing productivity of fixed assets (reduced by land, permanent crops and production quotas). |

Abstrakt | Zmiany zachodzące w gospodarce światowej, a w szczególności relacje między aspektami ekonomicznymi, środowiskowymi, społecznymi czy politycznymi stały się punktem wyjścia do rozważań nad ścieżką rozwoju społeczno-gospodarczego. Za jedno z nowych podejść, uznać można koncepcję - green economy. Wzrost znaczenia tego podejścia upatruje się w rosnących ograniczeniach utrzymania długofalowego wzrostu w tradycyjnym podejściu zgodnie z modelem Solowa i występowania okresowo znacznych odchyleń uzyskiwanych wyników rocznych od stanu równowagi. Odnosząc się do tego problemu za cel artykułu przyjęto wskazanie uwarunkowań rozwoju zielonej gospodarki w krajach Grupy Wyszehradzkiej. W celu identyfikacji oraz określenia oddziaływania poszczególnych czynników ekonomicznych, społecznych i środowiskowych na rozwój sektora zielonej gospodarki zastosowano regresję panelową. Zakres czasowy obejmuje lata 2004-2016. Ze względu na brak uniwersalnej metody oceny stopnia rozwoju tej koncepcji, przeprowadzone badanie może być uznane za jedną z propozycji w ramach przedmiotu literatury. Uzyskane w ten sposób wyniki mogą służyć do interpretacji uwarunkowań rozwoju zielonej gospodarki. |
Abstract | Changes in the world economy, and in particular relations between the economic, environmental, social and political aspects, have become the starting point for reflection on the path of socio-economic development. One of the new approaches is the green economy. The importance of this approach is reflected in the growing constraints to sustain long-term growth in the traditional approach according to the Solow model and the occurrence of periodic significant deviations from the state of equilibrium. Referring to this problem, the aim of the article was to indicate the determinants of the green economy development in the Visegrad Group countries. Panel regression was used to identify and characterize the nature and impact of individual economic, social and environmental factors on the development of the green economy sector. Time range covers the years 2004-2016. Due to the lack of a universal method for evaluating the degree of development of this concept, the study conducted may be considered one of the proposals within the literature. The results obtained in this way can be used to interpret the determinants of green economy development. |

Abstrakt | Artykuł opisuje ekonomiczne uwarunkowania prewencji i wypadków przy pracy. Badaniem zostały objęte duże przedsiębiorstwa przemysłu spożywczego na terenie województwa łódzkiego. W pracy ustalono model regresji prostoliniowej między rozpatrywanymi zmiennymi i dokonano oceny statystycznej skonstruowanego modelu. Z przeprowadzonych badań wynika, że koszty BHP ponoszone przez przedsiębiorstwa sektora spożywczego, mimo że wzrastały, były ogólnie niewystarczające i ponoszone zbyt późno. |
Abstract | The paper describes the economic conditions of prevention and occupational accidents. The study covers large enterprises of the food industry in the Lodz region. The straight line regression model between the considered variables was developed and statistically evaluated.. It can be concluded that the health and safety costs incurred by enterprises in the food sector, although they grow, are generally insufficient and incurred too late. |

Abstrakt | Albania has considerable potential for growth in the fruit and vegetable market. Its climate-arable conditions are very adequate for the successful growth of a wide range of fruits and vegetables. Albania has an interior market in development and a non structured exporting market. The study is aimed at estimating and identifying export growth opportunities and constraints for fruit and vegetable exporters. The paper investigates the opinions of producers and exporters in south-west Albania. A face-to-face interview survey method was conducted. Database elaboration was made through the SPSS program. An ordinary probit regression was used to evaluate the constraints of fruit and vegetable producers in Albania. We conclude that there are several problems that hamper exportation growth in Albania. Albanian producers are usually not able to penetrate into foreign markets because they are not part of consolidated marketing distribution channels. |

Słowa kluczowe | credits granted to individual farmers, preferential credits for agriculture, net profit, cooperative banks |
Key words | |
Abstrakt | The aim of the research was to determine whether and to what extent credits for agriculture, that is credits granted to individual farmers and preferential credit for agriculture, affected the level of net profit of cooperative banks in Poland in 2015–2017. Among others, it was established that credits granted to individual farmers are important for generating net profit for both small, medium and large cooperative banks. However, the values of the regression coefficient for this variable were low, with a slight increasing tendency. The variable, however, defining preferential credits for agriculture appeared only in two out of nine models constructed and with a negative sign. This concerned small and medium-sized cooperative banks. For large cooperative banks, preferential credit for agriculture were not of key importance in generating net profit. One can conclude that preferential credit does not bring financial benefits to cooperative banks. It is necessary to make financial revenues reliable, taking into account the costs of servicing preferential credits. |
