Метою виконаного дослідження є розвиток методичного інструментарію оцінювання рівня стабільності аграрних підприємств на основі дослідження стохастичних рядів значень результуючих параметрів. \u0000Методологія / методика / підхід. Під час виконаного дослідження застосовано метод моделювання стохастичних величин, зокрема, рівняння Ферхюльста для дослідження динаміки значень результуючого параметра відносно монотонно зростаючого ряду значень і різних значень коефіцієнта «скупчення щільності». Для прогнозування значень дисперсії результуючого параметра застосовано GARCH модель, а для визначення залежності стану підприємств від факторів внутрішнього та зовнішнього середовищ – застосовано регресійний аналіз. \u0000Результати. Прийнято на основі досліджень попередників, що значення логістичної функції Ферхюльста імітують поведінку стохастичної величини, тому цю функцію можна використовувати для вимірювання точки переходу системи із стабільного стану в стан нестабільності. Доведено, що, враховуючи стохастичну та рефлексивну природу розвитку аграрних підприємств, прогнозування їхнього стану доцільно здійснювати на основі порівняння дисперсій значень результативного параметра. Аргументовано, що застосування функції зміни степеневих коефіцієнтів дозволяє отримати найбільш повну інформацію про вплив суб’єктивних факторів внутрішнього середовища аграрних підприємств на їхній стан. \u0000Оригінальність / наукова новизна. Розвинуто методичний інструментарій оцінювання рівня стабільності аграрних підприємств, який базується на застосуванні рівняння Ферхюльста для дослідження динаміки значень результуючого параметра відносно монотонно зростаючого ряду значень і різних значень коефіцієнта «скупчення щільності», і, на відміну від наявних, дозволяє ідентифікувати точку біфуркації та встановити залежність результуючого параметра від факторів внутрішнього та зовнішнього середовищ аграрного підприємства. \u0000Практична цінність / значущість. Практична цінність розвинутого методичного інструментарію полягає в можливості його застосування керівниками аграрних підприємств для прогнозування їхнього стану із урахуванням впливу факторів внутрішнього та зовнішнього середовищ. Ураховуючи те, що прогнозування зводиться до одного результуючого параметра, то запропонований інструментарій є простим до застосування. Його доцільно використовувати для обґрунтування прийняття регулювальних рішень, зокрема, під час адаптивного управління та раціоналізації процесів управління персоналом й інтелектуальним потенціалом працівників.","PeriodicalId":398637,"journal":{"name":"Agricultural and Resource Economics: International Scientific E-Journal","volume":"21 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":"123797804","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 study, which results are submitted in the article, is to analyze the vertical price transmission along the milk supply chain in Ukraine and identify whether this price transmission is symmetric or asymmetric in terms of direction, magnitude, speed. \u0000Methodology / approach. To achieve the purpose of the study, we used the following research methods: logical operations (analysis, synthesis, induction, deduction) – to determine the structure of the milk supply chain, to make conclusions about main findings; the correlation analysis – to identify the tightness of links between farm’, processors’ and retailers’ prices; the trend modelling – to build the functions of the trend of prices of different levels of the milk supply chain; the regression modelling – to construct the regression functions of prices of downstream sectors of the milk supply chain; graphic – for visual presentation of main tendencies, pricing and price dynamics in the milk supply chain. The research was performed on the basis of the statistical data of the State Statistics Service of Ukraine for 2013–2020. \u0000Results. This paper presents the empirical evidence of asymmetric price transmission along the milk supply chain in Ukraine. The results of modelling proved asymmetric magnitudes of price growth at the organizational and technological stages of the milk supply chain: in the case of the farm prices of raw milk increase the processors’ and retailers’ prices grow up by a much bigger magnitude. There is no leg in price transmission in the milk supply chain, the price shocks at the farm level instantly pass to processors’ and retailers’ prices. The evidence of asymmetry of price transmission testifies the weaknesses of the market positions of farmers and consumers in the milk supply chain in Ukraine, points out the threats for the food security and sustainable development of all agents of this chain. \u0000Originality / scientific novelty. For the first time, the quantitative assessments of the magnitude and speed of the price changes in the process of price transmission in the milk supply chain in Ukraine were obtained.

Saltwater intrusion affected seriously the livelihood of mangosteen growers in Ben Tre, a coastal province in the Vietnamese Mekong Delta in 2016. This study assesses how saltwater intrusion influenced the livelihood vulnerability of the mangosteen households and communities. \u0000Methodology / approach. This study used the United Nations’ Livelihood Vulnerability Index (LVI) and a similar index from the Intergovernmental Panel on Climate Change (LVI-IPCC) using data from 196 interviewed mangosteen growers in Cho Lach district, Ben Tre province in 2016 and 2018. A total of twenty-five (25) indicators are applied to calculate the two indices, using data as exposure to saltwater intrusion and natural hazards (5), socio-demographic factors (11), and sensitivity of health, finance, and source of water for domestic use (9). \u0000Results. The analysis results show that mangosteen-growing households had a medium vulnerability in 2016 and 2018 based on both indices. However, they were extremely vulnerable due to saltwater intrusion in 2016, and a high household percentage had a moderate value in the vulnerability index. They did not experience how to respond to saltwater intrusion and received a late warning on saltwater intrusion from the local authorities and media. However, mangosteen-growing households had a quick adaptive behavior to shift to new crops to improve their income in 2018. \u0000Originality / scientific novelty. The study provides a set of indicators to assess the vulnerability of this low-vulnerable area based on past studies as well as the actual situation of the study area in 2016 and 2018 to determine what factors influenced the main components, LVI and LVI – IPCC.

This study aims to analyze economic coping strategies and their relationship to the food security of poor rural households. \u0000Methodology / approach. This research was conducted by comparing food crop farming households with those who farm plantation crops. The used data were sourced from surveys in four sample rural areas in two districts of Jambi Province, Indonesia, namely Merangin Regency and Tanjung Jabung Timur Regency. The used analysis tool was Structural Equation Modeling (SEM). \u0000Results. The results show that poor rural households’ economic coping strategies are still low, both in the context of a passive strategy (cutting back expenses) and an active strategy (generating income). Plantation households have a lower economic coping strategy than food crop farming households. The level of food security in food crop households is relatively good compared to that of plantation crop households. Nearly half of food crop households are categorized as having good food security, while only around 20 % of plantation crop households are so categorized.

The purpose of the article is to substantiate theoretical-and-methodological provisions for building investment portfolios in agribusiness by the criterion of minimizing environmental risk of selected investment-financing strategies. \u0000Methodology / approach. In the article, on the basis of the dialectical method of cognition, the following methods were used: abstract-logical – in the systematization of scientific papers on the problem of diversification and optimization of the agricultural investment portfolio; system analysis and comparison – in the study of portfolio theories and concepts; computational and constructive – in the analysis of environmental-and-economic factors of the profitability of agricultural land use; economic-and-mathematical modeling – in the process of modeling the optimal portfolio of agri-environmental investments by the criterion of minimizing the risk of a particular investor, caused by the action of soil degradation factor in Sumy region. The materials of the Main Department of Statistics in Sumy region and the Sumy regional branch of the Institute of Soil Protection of Ukraine have formed the informational basis of the research. \u0000Results. The optimization of the agri-environmental investment portfolio is due to the modification of the approach by the American Economist H. Markowitz “risk-return analysis” and its adaptation to the conditions of real investment. The paper uses a conservative approach to investment, which involves the construction of portfolios on the criterion of minimizing investment risk due to the influence of soil degradation for a particular investor. This factor requires the determination of the investor’s environmentally related risk, which manifests itself in the following directions: a) a decrease in crop yield due to the action of the factor of high soil pH; b) a decrease in the sales price for crop products because of contamination with heavy metals; c) an increase in the cost of agricultural production in deteriorated ecological conditions. Evaluation of agribusiness investment attractiveness on environmental-and-economic grounds provides for the consideration of the above areas from the standpoint of state, banking, foreign investment and self-investment. Assessment of investment quality identification is performed on the basis of calculation of the investor’s income elasticities to environmental risks on the example of Sumy region, which provides investment rationality decisions in the field of agricultural land use, considering environmental factors.
