This study aims to examine the relationship between human capital and environmental destruction. \u0000Methodology / approach. The analysis includes 56 years between 1961 and 2017 for 14 selected European countries. In the model established for the variables, the ecological footprint is used as the dependent variable, human capital and real national income per capita are used as independent variables. To select the appropriate test method in the analysis, we used the CADF panel unit root test, which considers the cross-sectional dependence. The Pooled Mean Group was used for model estimation. \u0000Results. In the study, it is emphasized that human capital has an important contribution to reducing the ecological footprint as an indicator of environmental pollution. According to the results of the PMG co-integration analysis, the increase in human capital reduces the ecological footprint in European countries. Since the European countries are developed ones, the availability of a good educational infrastructure is an important factor. It increases human capital. In addition, the high level of education and welfare in European countries is effective in increasing the number of environmentally sensitive individuals. This increases the environmental quality and therefore is an important factor in reducing the ecological footprint. \u0000Originality / scientific novelty. There are no studies in the literature examining the relationship between human capital and the ecological footprint of European countries. Therefore, this study closes a gap in the literature and takes its originality from the relationship between human capital and ecological footprint in European countries. \u0000Practical value / implications. The practical value of the results is that human capital reduces the ecological footprint by protecting natural resources, exhibiting a more environmentally friendly behavior, and realizing production that will minimize the damage to the environment.","PeriodicalId":398637,"journal":{"name":"Agricultural and Resource Economics: International Scientific E-Journal","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121600145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the article is to study the degree of disclosure of information about the risks of economic activity of enterprises in non-financial statements and to find ways to improve the organization and methods of analysis of such risks based on the financial statements of companies. \u0000Methodology / approach. The methodological basis of the study is a systematic approach, methods of generalization, comparison, abstraction, analysis, synthesis, induction and deduction, bibliometric analysis, cluster analysis, as well as methods of integrated economic analysis. The publications from the Scopus database, for 1988–01.04.2021, processed by VOSviewer software were the source of data for bibliographic and cluster analysis. The materials of the research on the state of disclosure of information about the risks of domestic enterprises of the food industry are based on their financial statements and management report. \u0000Results. The article analyzes the state and degree of disclosure of information about the risks of economic activity in non-financial reports of domestic food industry enterprises. It is established that the enterprises of the studied industry most often provide information about the following risks: economic, currency, financial, political, legal, judicial, interest, personnel, price, commercial, as well as liquidity risk and market risk. \u0000Originality / scientific novelty. Theoretical, methodological and organizational principles of risk analysis of companies based on non-financial and financial reports have been further developed. For the first time, we proposed our own approach to the methodology of analysis of such risks, based on financial reporting indicators. In particular, such analytical indicators include: financial risk – solvency, financial leverage; credit risk – investment coverage ratio, return on equity, return on assets; liquidity risk – coverage ratio, quick liquidity ratio, absolute liquidity ratio. \u0000Practical value / implications. The practical value of the research is that the results obtained by the authors will contribute to the disclosure of information about the risks of economic activity of enterprises in non-financial statements. Analysis of the status and level of disclosure of information about the risks of domestic food industry enterprises in non-financial reports showed that most companies provided information about the following risks: economic, currency, financial, political, legal, judicial, interest, personnel, price, commercial, and risk liquidity and the risk of changes in market conditions. As a result, the author's methodological approach to the analysis of internal risks of the studied industry (credit, financial risks, liquidity risk) is proposed.

The research described in the article was carried out according to the method developed by the authors for evaluation of the level of the usage of social instruments for human resource management on the enterprise. This method is based on the self-evaluation of social instruments for human resource management by HR managers together with top managers of the enterprise, comparing these results with the desired indicators of development of each of the social instruments in accordance to strategic guidelines, and development of a Plan of actions on the development of social instrument for human resource management. \u0000Results. According to the results of authors’ method approbation of analysis of the level of the usage of social instruments for human resource management on the agro-processing enterprises of Ukraine it is established that the usage of social instruments of human resource management by these enterprises is estimated as average (41–58 points). The predominant social instruments for human resource management on the enterprises under investigation are the welfare of employees and working life, planning and development of employees’ career, efficiency management and conflict management. The low level of the usage of social instruments of employees’ participation in enterprise management, setting-up of effective social partnership, feedback, counseling and coaching reflect the out-of-date understanding of the staff as a work force rather than the most important resource. On the basis of the conducted analysis it was determined that unsystematic usage of social instruments for human resource management is observed at the enterprises of agro-processing industry of Ukraine.

This study uses the following methods: expert assessments and monographic (for the assessment of economic losses due to crop productivity loss from spreading soil erosion); graphical (for building three-dimensional graphs); econometric modeling (to develop a mathematical model of the dependence of the gross crop production and income from sales per 100 hectares from the share of eroded arable land in its total area and production costs in crop industry per 100 hectares); abstract-and-logical (for generalization of the research results). To solve the assigned tasks, linear and quadratic econometric models (production functions) were developed using a dataset (і) from 168 observations (on the example of Ukrainian regions for 2010–2016) and (ii) from 189 observations (on the example of districts of Kharkiv region for 2010–2016).

Our expert assessment of economic losses due to crop productivity loss from spread of soil erosion on agricultural land in Ukraine is 224 mln USD. The obtained results confirm the hypothesis about the negative relationship between gross crop output and the level of land erosion. The obtained data confirm that an increase in the area of eroded arable land by 1 % leads to a decrease in the gross output of crop production by 0.20 % per 100 hectares of agricultural land in total, and in the third group of the studied subjects (the share of eroded arable land in their total area is more than 50 %) – by 0.61 %, respectively. \u0000Originality / scientific novelty.

The main purpose of the research is to substantiate the methodological approach of defuzzification and to define its peculiarities in the process of estimating the value of agricultural lands. \u0000Methodology / approach. The research purpose included the use of a set of appropriate methods. In particular, the fuzzy logic techniques formed the basis of the research. The system approach was used in order to determine the role of land resources in the enterprise potential and the corresponding spheres of their management. The analysis and synthesis methods were used in the process of definition of impact factors of land resources value. The cartographic method was used for the needs of graphical display of humus content in the land plots of the analyzed enterprise. The generalization method was used in the process of forming conclusions. \u0000Results. The article defines the peculiarities of defuzzification in the process of estimating the value of agricultural lands. The results provided the methodological basis for considering the qualitative metrics in the process of estimation as well as for granting the numerical interpretation for linguistic variables. The corresponding methodology was overviewed at the example of land plot size. The quantitative reference limits for “small”, “medium” and “large” land plots were defined. Research results made it possible to form the sequence of stages, which are to be undertaken, in order to provide numerical values for qualitative characteristics of agricultural lands.

Under the background of the climate change and other crises, the world food system is becoming increasingly vulnerable to price fluctuations. This highlights the need to consider and better manage the risks associated with price volatility in accordance with the principles of a market economy and simultaneously protecting the most vulnerable groups of population. Responding to these challenges, in this study we aim to determine the main parameters of time series of potato sales prices in agricultural enterprises in Ukraine, to build an appropriate model, and to form a short-term (one-year) forecast. \u0000Methodology / approach. We used in the research the data from the State Statistics Service of Ukraine on average monthly sales prices of potatoes in agricultural enterprises from December 2012 to July 2021 (104 observations) adjusted for the price index of crop products sold by enterprises for the month (with December 2012 base period). Decomposition was used to determine the characteristics of the time series; exponential smoothing methods (Holt-Winters and State Space Framework – ETS) and autoregressive-moving average were used to find the model that fits the actual data the best and has high prognostic quality. We applied the Rstudio forecast package to model and to forecast the time series. \u0000Results. The time series of potato sales prices in enterprises is characterized by seasonality (mainly related to seasonal production) with the lowest prices in November, and the highest – in June; although, other periods of price growth were identified during the year: in January and April. The ARMA (2, 2) (1,0)12 with a non-zero mean was found to be the best model for forecasting potatoes sales prices. ARMA (2, 2) (1,0)12, compared to the state-space exponential smoothing model with additive errors – ETS (A), better fits the observed data and provides more accurate forecasting model (with lower errors). Forecast made with ARMA (2, 2) (1,0)12 shows that potato sale prices in agricultural enterprises in November 2021 (months with the lowest price) will range from 2154.76 UAH/t to 7414.57 UAH/t, in June 2022 – from 3016.72 UAH/t to 14051.63 UAH/t (prices of July 2021) with a probability of 95%.

This research deepens the methodological basis for food prices modelling and forecasting, thus contributing to the agricultural economics science development. The obtained results confirm the previous research findings on the better quality of food prices forecasts made with autoregressive models (for univariate time series) compared with exponential smoothing.

There are determined new conceptual approaches to the development of indicators of social capital of the agricultural sector for meso- and microlevels, which take into account industry specifics, are determined by groups of factors of its formation and results of use, and reflect the main components of social capital – innovation (norms), relational (trust) and structural (social networks) social capital. On the basis of the method of analysis of hierarchies the comparative it was carried out an estimation of factors of formation of social capital of two domestic agroholdings which results correspond to results of the analysis of indicators of results of its use \u0000Originality / scientific novelty. The methodological bases of the analysis of social capital of the agrarian sphere through complex measurement of its components by means of system of indicators on meso- and microlevels taking into account branch features were improved, factors of formation and results of use of social capital were systematized. \u0000Practical value / implications. The obtained results allow substantiating the key approaches to measuring the social capital of the agricultural sector, which makes it possible to obtain comprehensive information for decision-making regarding its further formation and effective use.","PeriodicalId":398637,"journal":{"name":"Agricultural and Resource Economics: International Scientific E-Journal","volume":"145 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114052590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
