The aim was to create a model of representative marketing communications transition from the formation of meanings to the formation of trends by using framing as an impact marketing tool. To accomplish the tasks set, the work uses the selection of general scientific and special methods and techniques of scientific research, such as the method of semantic, morphological, comparative and critical analysis, the ontology construction method, system-structural and functional approaches, simulation modeling, etc. The brand phenomenon is considered from the point of view of social constructivism, as a result of which seven principles of brand existence in the concept of communications with society have been identified. Two types of frameworks, which are used when building a narrative in the context of representative brand actions, have been substantiated theoretically. The methodology for using these frameworks is considered from the position of marketing, logical, communicative and social metrics included extensional and intensional equalities, as a result of which a model, that allows determining the transformation of brand communications into meanings or trends and its trendy potential, has been built. The following framing tools have been analyzed and adapted for marketing purposes: Overton Window, Hallin’s Spheres, Opinion Corridor, Spiral of Silence, Echo Chamber and Epistemic Bubble. Reframing is considered from the point of view of culture, namely the processes of inculturation. The difference of approaches has been revealed and a model of the transition of using framing tools from constructing meanings to constructing trends has been built. This model allows to minimize the problem of incorrect decoding of information during representative and communicative actions of the brand","PeriodicalId":33449,"journal":{"name":"Ekonomika rozvitku","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48161819","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}

This study aimed to investigate perceptions of a limited sample of South Africans regarding the sugar-sweetened beverages tax based on certain economic factors, and whether participants perceived any likely benefit from the tax. These perceptions were compared with perceptions identified in selected foreign jurisdictions that have levied such a tax. A survey questionnaire was selected as the primary method of data collection. This questionnaire was administered to post-graduate Accounting students, aged twenty-one years and older, studying at three residential universities in South Africa. An extensive analysis of literature available on sugar-sweetened beverage taxes, both locally and internationally, was conducted. The two main constructs (construct 1: perception of the sugar-sweetened beverage tax and the price of sugar-sweetened beverages and construct 2: the social impact of the sugar-sweetened beverage tax) were analyzed using descriptive statistics. This study found that there is a significant association between gender and perception that the sugary beverage levy will be beneficial to health, with female perceptions of the benefit of the sugary beverage levy being greater than that of males. The study found that perception of the sugar-sweetened beverage tax may depend on several factors, closely linked to individual beliefs and cultures, and thus different populations may have different perceptions of the tax. The findings about sugar-sweetened beverage consumption trends across gender, ethnicities and physical activity groups can help guide targeted strategies to reduce consumption.","PeriodicalId":33449,"journal":{"name":"Ekonomika rozvitku","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46984321","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}

One of the ways to ensure the effectiveness of this process is the use of innovative educational technologies aimed not only at the formation of professional competences, but also at the development of creativity which, in the future, will contribute to the search for non-standard ways of solving real problems. The purpose of the work is to study the influence of interactive educational technologies based on the concept of design thinking on the success of students of economic specialties and their internal motivation to study mathematical disciplines. The format of a business game has been chosen as a method of implementing the concept of design thinking. It involved the construction of a mathematical model of a real economic problem and the use of a mathematical apparatus to solve it. In order to evaluate the effectiveness of gamification it has decided to distribute students according to academic performance and students ranked classes according to their preferences using the method of hierarchies analysis. The experience of implementing business games demonstrated by the example of the discipline “Operations Research and Optimization Methods” confirmed the effectiveness of this technique in the process of studying the disciplines of the mathematical cycle precisely due to the increase in students’ internal motivation. Compared to traditional teaching methods, the formation of students’ professional competencies has been enriched by the experience of solving transdisciplinary tasks. The results of the study allow us to conclude that the professional competencies of future economists are significantly improved thanks to the use of a business game in the learning process where a real economic problem is adapted to the topic of the discipline.","PeriodicalId":33449,"journal":{"name":"Ekonomika rozvitku","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47449345","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}

Such changes impose new requirements on marketing of educational services aimed both at attracting new consumers and at keeping and preserving those who are already studying. Transformations of approaches in marketing of education are a consequence of its development. The development of marketing of educational services during distance online learning is impossible without the introduction of modern digital technologies and involves taking into account the rules of netiquette. The application of the principles of netiquette in distance learning will contribute to the resolution of contradictions in marketing of educational services and its development. This determines the relevance of the chosen research topicality. The purpose of the study is to determine the principles of netiquette as a basis for the development of marketing of educational services in the process of distance learning. The work uses such research methods as the method of logical generalization, the method of analysis and synthesis, the method of content analysis, and the method of focus group interview. The result of the conducted research is the development of general principles of netiquette in the organization of distance learning, taking into account the specifics of educational services. The concept of relationship marketing, provisions on distance learning and classic general principles of netiquette were used as a theoretical basis for the substantiation of these principles. The practical basis for the conclusions was the analysis of cases of US universities regarding netiquette policies, as well as the results of a focus group interview with students of institutions of higher education regarding the norms and rules of behavior in the Internet space during the interaction of teachers and students in the process of distance learning. The practical significance of the application of the rules of netiquette is that it ensures digital freedom of communication, attracts a larger segment of consumers of the educational service and will contribute to the formation of a new type of academic community.","PeriodicalId":33449,"journal":{"name":"Ekonomika rozvitku","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47284011","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}

Digital technologies are changing tourism preferences, consumption, and the essence of the interaction of tourism business entities. In this context, the study aims to identify the specifics of the relationship between the level of international tourism development and digital technologies. The purpose of the study is to determine the features of the relationship between the level of international tourism development and digital technologies. Methods such as bibliographic, standardization, correlation analysis, factor analysis without rotation and, factor analysis with rotation using the Varimax method, comparative analysis, graphical analysis were used in the article. The World Bank International Tourism Indicators (such as expenditures, the number of arrivals, the number of departures, and receipts) and the Network Readiness Index were used for the analysis. The data covers 130 countries for 2020. The research identified correlations between indicators of international tourism development and the Networked Readiness Index and its components. The analysis shows that there is a direct relationship between the analyzed indicators. Also, factor loadings were calculated in the paper using factor analysis without rotation and factor analysis with rotation by applying the Varimax method. The Varimax rotation method made it possible to identify two well-defined factors, one closely related to the Networked Readiness Index sub-indices and the second – to the international tourism indicators. By using factor analysis without rotation, one factor was identified. Based on this analysis, it was concluded that the level of international tourism development and the degree of digitalization of the economy are linked. In the case of determining the relationship between the sub-index Networked Readiness Index Technology and expenditures and the number of arrivals, this relationship was not identified. The results highlight the importance of digitalization in the tourism business. In doing so, the paper points out that in addition to digital technologies, tourism companies should also pay attention to other factors such as security, risks, fluctuating economic situation, changing geo-economic and social conditions, etc.","PeriodicalId":33449,"journal":{"name":"Ekonomika rozvitku","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49259967","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}

In practice, the methodology for evaluating and selecting data depends on market expectations and takes into account the requirements of the general public rather than industry professionals, so the question arises as for choosing the optimal system for evaluating the performance of multinational enterprises from different countries due to various managerial approaches, tax and accounting standards. The article aims to review the most common indicators and ratios used in international financial comparisons, and to prove (on the example of a global rating approach) that only the complex business analysis, even at a prior level, should be used for the reliable estimation of a company’s stability in the market. The study uses a database of key financial indicators of 2,000 companies included in the Forbes rating, such as sales, profit, asset and market value. Based on these indicators, the financial ratios were calculated and the characteristics of groups of enterprises were given by the methods of descriptive statistics. Net profit is emphasised as a key performance indicator, and it has been proven that the companies with the highest asset value do not have excessive financial ratios. The latest Forbes ranking covers companies from 61 countries, the leaders in headquartering the companies are the United States, China and Japan. It has been found that most companies have assets of up to $500 billion, while the market value of assets (calculated on the value of placed securities) is on average twice as low. The ranking also includes unprofitable enterprises (about 15% of the total), which indicates the lack of effective mechanisms for assessing the effectiveness of management of multinational enterprises and possible errors in investment decisions, as the focus is more on working capital and market coverage (sales) than the ability of management to develop strategic decisions. In the most stable companies, the ratio of net profit to sales does not exceed 20%, which proves the assumption of the advantage of moderate development and financial management. There is almost no correlation between profit/sales and asset value, while it is the strongest between asset value and market value of the company, and profit and market value. The companies with the largest assets have lower absolute and relative financial indicators than the average in the total sample of 2000 enterprises (with some exceptions).

In a fragile, non-linear and incomprehensible globalized world, a shift in society’s values can be triggered by global upheavals that threaten the survival of humans as a biological species. In the 21st century, society feels the danger of war, the threat of the spread of dangerous viruses, and the digitalization of all human life. The purpose of the conducted research is to identify the main values of Ukrainian youth and their transformation in the conditions of economic crises and war danger. Sociological research was conducted to verify hypotheses as to accelerating the transformation of Ukrainian youth values. The first wave of research on the value orientations of Kharkiv student youth was conducted in March 2014, similar research was conducted during November 2020 – January 2021, as well as in April-May 2022. The results showed that absolute and family values traditionally have a high level of priority for Ukrainian youth, regardless of living conditions and external factors. However, changes have taken place within value groups. With the aggravation of the military danger, the values of freedom, honesty, and preservation of life came to the fore. During the military threat, the importance of the group of civic and national values increased significantly. Among the national ones, the greatest growth was gained by the state independence of Ukraine, patriotism, readiness to defend the Motherland, love for the native culture, language, and traditions. Digital values have shown sufficient stability of results compared to pre-war times. Digital government services and digital technologies to improve energy efficiency have grown.

This raises the issue of finding an effective mechanism for economic security in general and financial security in particular, which are important elements of how macroeconomic components work. The purpose of the study is to develop models that allow assessing the impact of an energy “shock” on financial security indicators, to identify the threshold values of exogenous variables at which the “shock” has a destructive influence on the level of financial security and can lead to the financial system destabilization. The work uses a branched structure of scientific methods which consist of theoretical and empirical research of the financial security for macroeconomic systems. The main results of this work are devoted to the consideration of the problem of how to design effective mechanisms for ensuring financial security under the conditions of exogenous “shocks” of the global economy. It considers the concept of “shock” and gives the examples of the impact of “shocks” on macroeconomic indicators. The work highlights the energy “shock” as dominant for the analysis and formation of an effective macroeconomic stability policy. The information area of research features is substantiated, including BRENT oil price data and indicators of monetary and currency security, such as the rate of inflation and the exchange rate. Emphasis on subsystems of monetary credit and currency security is made due to the importance of these channels of crisis infection in order to ensure financial security. The value of the lag in the model is substantiated with the help of information criteria; evaluation and testing of the quality of the model have been carried out; system stability has been assessed based on the impulse response function, the TVAR model has been developed. The areas of change of the exogenous variable reflecting the statistically significant impact of the energy “shock” on the rate of inflation are analyzed. Thus, the obtained results made it possible to identify the regimes of energy security, which become a channel of infection of the financial sphere and a significant increase in the level of inflation. Practical significance includes the versatility and applicability of the evaluation approach for research due to the ability to use the entire algorithm as a complete ensemble of models.

The purpose of the paper is to identify the manifestations of macroeconomic instability in the period before and after the pandemic and to demonstrate the effectiveness of the use of fiscal instruments of regulatory competition to achieve the goals of the stabilization policy of the governments of countries with developed economies. The research is based on the categories of theoretical and empirical levels of knowledge. The use of the method of analysis, abstraction and synthesis, induction and deduction, as well as the system-structural method, the method of idealization, made it possible to identify new forms of manifestation of the phenomenon of fiscal regulatory competition and establish its place in the implementation of the stabilization and incentive programs of the government. It was found that the stimulation of economic activity and the increase in net exports using the instruments of fiscal neo-protectionism occurs due to a simultaneous increase in employment and a decrease in the cost of domestically produced goods, accompanied by the rise in relative consumer prices for imported goods. Using economic analysis and mathematical modelling methods confirmed the hypothesis about the stimulating effect of fiscal policy. Based on the regression analysis of the mechanism of the fiscal channel of the stabilization policy of developed countries, which influenced the dynamics of the conjuncture in the period from 2018 to 2022, a conclusion was drawn regarding the strength of its impulse. It has been found that the fiscal channel less clearly transmits the impulse from the growth of expenditures (financed by loans) to the real sector. It is assumed that in the process of signal transmission, it scatters. It has been established that in the short term, in a recession, the fiscal impulse also does not cause a jump in inflation. In the context of inflationary growth in the United States, Japan, and Germany, there is a turn towards tightening monetary policy, which limits the use of financial instruments to counter the recession and therefore increases the demand for the benefit of fiscal tools to counter the recession","PeriodicalId":33449,"journal":{"name":"Ekonomika rozvitku","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46790137","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}
