Research background: International market selection is an essential issue for big companies that supply food products. Different types of decision factors and different characteristics of different Oeconomia Copernicana, 12(1), 99–124 100 international markets have brought up a complicated decision-making problem for food supply companies. In order to select the most suitable and profitable market, food supply companies have to consider several qualitative and quantitative factors, including social, political, economic, and ecological aspects. Purpose of the article: In order to overcome international market selection issues, the current study develops a novel integrated decision-making tool. Methods: A novel decision-making model of market analysis is developed as an extended model of Market Attractiveness and Business Attractiveness (MABA) analysis based on the Multiple Attribute Decision Making (MADM). To improve the MABA analysis model, we combine the EDAS method with MABA analysis to empower decision-makers in food supply companies to evaluate several international markets and select the most profitable market for their products. Findings & value added: In this study, we first identified the most important and frequently used decision factors for market analysis problems within MABA analysis under two categories: market attractiveness and business attractiveness. To show the proposed methodology's applicability and feasibility, we perform a case study for a food supply company in Iran that supplies products to Middle East and Asian countries. In order to investigate the reliability of the obtained results, we perform a sensitivity analysis concerning the importance of involved decision factors. The proposed decision-making tool results suggest that the model can be used as a reliable tool for market analysis problems. To sum up the long-term value of the study, we have developed a novel decision-making tool using MABA analysis and the EDAS method. No study integrates any MCDM methods with MABA analysis to the best of our knowledge. Integration of EDAS method with MABA analysis empowers decision-makers in market selection division to use more systematic methods for evaluating several markets.

Research background: Among academicians, a growing interest in brand valuation methods can be observed since the 1980s, when it became obvious that firms have off-balance sheet assets which have a significant effect on their value. Moreover, in a number of cases, the need to value the brand arises due to the reporting requirements or transactional and other intrafirm reasons. The existing methods used so far have commonly focused on changes in variables such as sale prices, changes in customer behaviour, or sales volumes and very often lead to different results, even when valuing the same brand. We believe that the risk factor has been neglected in these methods, although having a significant impact on the brand valuation. Purpose of the article: The aim of this paper is to formulate an alternative brand valuation approach based on the risk difference. This is defined as the difference between the risk to which a producer with a certain brand is exposed and the risk of the producer without a brand. Methods: Firstly, a set of assumptions was defined concerning the issue what conditions are required to be applied to use the proposed methodological approach. Next, the concept itself is formulated and tested while using the case study approach. Hence, in conditions of a model company, the method was verified with specific data. The results were also compared with the reproduction cost approach. Findings & value added: This paper presents a novel brand valuation method based on the risk difference. Building on a thought experiment, we compare an incumbent with a brand rather than with an average producer, which is a commonly used approach, with a new entrant to the market. We argue that in comparison to existing methods, our methodological approach reduces the number of unobservable inputs in the brand valuation process, and thus increases the accuracy and reliability of its results. Our method supports both researchers and practitioners to establish a better understanding between the well-established financial theories and new directions in brand valuation research.

Research background: We are guided by concepts linking political trust with the perceived rank of people in the wealth hierarchy, their confidence in other people, and the means they use to learn about events at home and abroad. Purpose of the article: The aim of the article is to assess and analyse at the micro level the impact of subjective welfare, interpersonal trust and the intensity of usage of television & radio or the Internet to search for news on political trust in four levels of Russian government. Methods: The study is based on microdata from the Life in Transition Surveys provided by the European Bank for Reconstruction and Development. Ordinal logit regressions are constructed to Oeconomia Copernicana, 12(1), 77–98 78 evaluate the impact of test and control variables on political trust in the Russian president, federal, regional, and local governments in 2010 and 2016. Findings & value added: We identify a reverse of political trust in the upper levels of the Russian government between 2010 and 2016, when the impact of perceived welfare level changes from positive to negative. This phenomenon is explained by the focus of the policy of the federal centre on sup-porting the poor groups of the population, as well as its distancing from business. In contrast, the positive, albeit inconsistent, effect of subjective wealth on trust in lower-level governments is due to the benefits that businesses can gain from interaction with local authorities. We find the positive impact of controlled television and radio on trust in the upper echelons of power, along with the negative impact of the freer Internet on political trust in regional and local authorities. We also confirm the hypothesis of a positive and significant relationship between interpersonal and political trust, highlighting the role of social capital. Finally, our research shows that in systems of the hierarchical type, such as Russia, specific mechanisms for maintaining political trust are established. They are associated with the redistribution of public expectations and claims to different branches of government. The results obtained are applicable for managing political trust through building a democratic state and civil society.

Research background: In determining the prices in road transport, carriers usually use the calculations based on a so-called routes utilisation coefficient, which allows the carrier to also take the possibility of the return rides without load into account Currently it is usually used as a constant from the interval from zero to one Purpose of the article: Considering a different offer of return transport from individual European Union (EU) countries, it can be assumed that the routes utilisation coefficient should have different values because there is a varying level of non-zero probability that the vehicle will return without a load This study therefore proposes a new approach to determining the value of this coefficient based on transport direction The study also aims to identify clusters of EU countries, for which the common value of the coefficient should be set Methods: The Analysis of Variance (ANOVA) test was used to verify the assumption of the differences among the means of transport offers Cluster analysis was used to identify the aforementioned groups of countries This analysis is based on real data on transport offers to Slovakia from 1 different EU countries Findings & value added: The results of the analysis can also be used in other EU countries because if significant differences in transport offers to Slovakia exist in individual countries, there is a reasonable assumption that this conclusion will also be valid in other countries The analysis demonstrated that it is more appropriate to use the routes utilisation coefficient with various values, dependent on the transport direction For the transport companies, implementation of the obtained results into practice is beneficial to increase their competitiveness through the more precise setting of transport prices, but also to the optimisation of the transport price itself with regard to the expected costs

Research background: Circular economy is of great importance, as it plays a vital role in ensuring the reuse of waste created and, therefore, reduces the waste of limited resources, which is the primary goal of the general economic concept. In line with the circular economy, sustainable development gains great attention, as the United Nations announced the sustainable development goals that should be reached by 2030. Hence, the current paper aims at examining whether the circular economy could be treated as an effective assistance tool for sustainable development of OECD countries. Purpose of the article: The paper aims to investigate whether the circular economy could serve as an assistance tool for sustainable development and, therefore, seeks to determine if the circular economy could directly impact a country’s sustainable development. Methods: First, the countries chosen were prioritised using the Analytic Hierarchy Process (AHP) and the Evaluation Based on Distance from Average Solution (EDAS) methodologies.

Research background: The innovation in Shar??ah-compliant banking products has resulted in the rapidly increasing size of assets in Islamic banks worldwide. The assets of such banks have been growing twice as fast as those of conventional banks. Islamic banks do not depend on conventional interest, speculation, or complex derivatives stemming from banking operations. Instead, their actions in respect of profit/risk sharing, and the clarity of the contract are consistent with Islamic Shar??ah principles, which seek to promote a more equal society. Purpose of the article: This research aims to identify and compare factors influencing the liquidity of Islamic and conventional banks in Europe. Candidate factors are sought amongst profitability, credit quality, credit expansion and capital adequacy indicators. Methodology: First, relevant financial ratios for 249 observations on Islamic banks and 2,306 observations on conventional banks are selected and compared for the period 2013?2017. Second, liquidity is explained separately for each type of banks by panel data regression to identify its determinants in a comparative context. Findings & value added: The results indicate that the impact of the net interest margin on the liquidity ratio of Islamic banks is insignificant, which is obviously due to the prohibition of the use of interest (riba). To the contrary, in conventional banking a higher net interest margin results in a reduction in liquidity. Capital adequacy has a positive influence upon liquidity in both types of banks, but in Islamic banking, the influence is 5.4 times greater. The findings strongly suggest that the liquidity of Islamic and conventional banks is affected by different factors.

Research background: The paper focuses on the research of investors? decisions with regard to shares of all 12 banks listed on the Warsaw Stock Exchange during the first half of 2020. It examines the behavior of a subindex reflecting bank shares? prices against the main WIG index WIG and 14 sector subindices. The authors identify groups of banks with different investors? responses. They also classify banks into separate groups on the basis of changes in the fundamental indicators describing their economic and financial performance. The study concentrates mainly on the verification of the stability of this attribution, explaining reasons for its modifications over time. Purpose of the article: To identify the characteristics of bank clusters determining different capital market responses to their listed shares and to explain the reasons for volatility in investors? behavior within the analyzed period. Methods: The methodology of the research can be described in three areas. The first is the statistical analysis with the emphasis on the use of a quarter range to capture changes in the volatility of share prices. The second area is the clustering k-means method based on the interpolated ? from quarterly to daily ? measures of the bank?s financial condition. This mathematical approach is a novelty in finance and economics. The last, third, area is forecasting with the use of linear regression analysis, which is the key factor in determining the abnormal rates of return. The indicated areas are combined through a generally understood correlation analysis. Findings & value added: Large retail banks have been less affected compared to medium-sized ones with relatively rich corporate portfolios. The initial market reaction reflected concern about the resistance to the crisis of poorly capitalized banks with mean liquidity buffers. Upon the announcement of government support, investors? approach to the shares of banks of differentiated economic and financial performance conformed accordingly. These findings are valuable in the long term especially from the perspective of supervision authorities? policy during external shocks. The presented study suggests designing flexible and tailor-made regulatory approach aligned with the defined bank clusters. Its value added also consists in proposing a new method of analysis, combining interpolation and automatic clustering, which has proved to be adequate for the study of a bank?s financial condition based on daily frequency data. Furthermore, assuming the same length of the estimation window, a close relationship is shown between the results of clustering and the forecasts based on different measures of rates of return.

Research background: Covid-19 has affected the global economy and has had an inevitable impact on capital markets. In the week of February 24?28, 2020, stock markets crashed. The index FTSE 100 decreased 13%, while the indices DJIA and S&P 500 fell 11?12%, the biggest drop since the 2007?2008 financial and economic crisis. It is therefore of interest to test the random walk hypothesis in developed capital markets, European and also non-European, in order to understand the different predictabilities between them. Purpose of the article: The aim is to analyze capital market efficiency, in its weak form, through the stock market indices of Belgium (index BEL 20), France (index CAC 40), Germany (index DAX 30), USA (index DOW JONES), Greece (index FTSE Athex 20), Spain (index IBEX 35), Ireland (index ISEQ), Portugal (index PSI 20) and China (index SSE) for the period from December 2019 to May 2020. Methods: Panel unit root tests of Breitung (2000), Levin et al. (2002) and Hadri (2002) were used to assess the time series stationarity. The test of Clemente et al. (1998) is used to detect structural breaks. The tests for the random walk hypothesis follows the variance ratio methodology proposed by Lo and MacKinlay (1988). Findings & Value added: In general, we found mixed confirmation about the EMH (efficient market hypothesis). Taking into account the conclusions of the rank variance test, the random walk hypothesis was rejected in the case of stock indices: Dow Jones, SSE and PSI 20, partially rejected in the case indices: BEL 20, CAC 40, FTSTE Athex 20 and DEX 30, but accepted for indices: IBEX 35 and ISEQ. The results also show that prices do not fully reflect the information available and that changes in prices are not independent and identically distributed. This situation has consequences for investors, since some returns can be expected, creating opportunities for arbitrage and for abnormal returns, contrary to the assumptions of random walk and information efficiency.

The index FTSE 100 decreased 13%, while the indices DJIA and S&P 500 fell 11?12%, the biggest drop since the 2007?2008 financial and economic crisis. It is therefore of interest to test the random walk hypothesis in developed capital markets, European and also non-European, in order to understand the different predictabilities between them. \u0000Purpose of the article: The aim is to analyze capital market efficiency, in its weak form, through the stock market indices of Belgium (index BEL 20), France (index CAC 40), Germany (index DAX 30), USA (index DOW JONES), Greece (index FTSE Athex 20), Spain (index IBEX 35), Ireland (index ISEQ), Portugal (index PSI 20) and China (index SSE) for the period from December 2019 to May 2020. \u0000Methods: Panel unit root tests of Breitung (2000), Levin et al. (2002) and Hadri (2002) were used to assess the time series stationarity. The test of Clemente et al. (1998) is used to detect structural breaks. The tests for the random walk hypothesis follows the variance ratio methodology proposed by Lo and MacKinlay (1988). \u0000Findings & Value added: In general, we found mixed confirmation about the EMH (efficient market hypothesis). Taking into account the conclusions of the rank variance test, the random walk hypothesis was rejected in the case of stock indices: Dow Jones, SSE and PSI 20, partially rejected in the case indices: BEL 20, CAC 40, FTSTE Athex 20 and DEX 30, but accepted for indices: IBEX 35 and ISEQ. The results also show that prices do not fully reflect the information available and that changes in prices are not independent and identically distributed. This situation has consequences for investors, since some returns can be expected, creating opportunities for arbitrage and for abnormal returns, contrary to the assumptions of random walk and information efficiency.","PeriodicalId":46112,"journal":{"name":"Oeconomia Copernicana","volume":" ","pages":""},"PeriodicalIF":8.5,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41561276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Research background: SMEs represent an integral part of the economy environment in a majority of the countries all over the world. They signify the most efficient, progressive, and important part of the advanced economies. The long-term effort of the EU countries, as well as other advanced economies is to create quality and stable conditions for their development in order to be able to respond to all the possible changes in the business environment that is being changed to more and more comprehensive in the recent time. Purpose of the article: The objective of the contribution is to examine administrative and legislative obstacles to SMEs business in the Czech Republic and Slovakia and the quantification of the differences in perceiving legislative and administrative obstacles to business by entrepreneurs in both countries. Methods: A questionnaire survey was conducted within SMEs in the Czech Republic and Slovakia in 2019. The research sample included 641 SMEs, 312 from the Czech Republic and 329 from Slovakia. We focused on 5 dimensions related to legislative and administrative obstacles to SMEs business within which selected statements were examined. Contingency tables were used to analyze the ratios of the examined variables. Findings & Value added: The differences detected in both countries in the respondents´ perception and assessment are evidence of the changes in the business environment of both countries, giving rise to the questions about the extent to which the legislative and administrative obstacles, as well as the obstacles related to law enforcement and bureaucracy are acceptable and by which groups of entrepreneurs. The results of the research provide valuable findings for the creators of regional and national policies, and represent a valuable basis for the creation of the concepts focused on the SMEs´ development in both countries. The results of the study also support the implementation of follow-up research in this area that will reveal other determinants affecting the development of SMEs. They also create a valuable platform for the construction of national and international benchmarking indicators in this area and the implementation of comparative analyses. This will also support the methodological area necessary for a creation of high-quality concepts and strategies.
