Additionally, the ?One-Belt One-Road? (OBOR) initiative was proposed by the Chinese government to further promote China in the international market.\u0000Purpose of the article: The article explores the role of the OBOR in China?s exports and global value chain. It aims at: 1) verifying how OBOR impacts the volume of China's export and value-added export to its partners. 2) checking whether or not OBOR strengthens the industrial connection between China and its participants at the GVC level. 3) examining the different roles of corridors in China's exports and GVC.\u0000Methods: The empirical analysis is based on the augmented gravity model of international trade, which comprises China and its 197 partners in the period 2000?2018. The model is estimated for gross export as well GVC measured by domestic value added in export and the value contributed by a partner to China?s exports.\u0000Findings & value added: In general, there is a significant positive correlation between OBOR and the volumes of China?s export, domestic value-added trade and the value of partner?s contributed in China?s export. However, some of the results are blurred by OLS and FE methods. The author points out that FE-PPML estimation methods are more adequate. Among the six economic corridors, Bangladesh-China-India-Myanmar (BCIM), China-Pakistan (CP) and China Indochina Peninsula (CIP) were proven to play a prominent role in promoting China?s export, DVA and strengthening the links of global value chains. It is worth noting that the China-Mongolia-Russian Federation (CMRF) corridor harms China's export and DVA trade, and at the same time promotes countries in its region that benefit from trade with China.","PeriodicalId":84667,"journal":{"name":"Equilibrium","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45240034","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}

Although many studies focus on the impact of ownership on dividend payouts, there is still a lack of research on the influence of the contestability and collusion of the largest shareholders on the catering effect of dividends. This research gap motivated us to investigate this issue and determine whether the interactions between large shareholders have an impact on aligning dividends with investor sentiment.\u0000Purpose of the article: The article assesses the impact of the relationship between the largest shareholders (i.e., contestability or collusion) on the adjustment of dividend payouts to investor sentiment. The following research hypothesis has been formulated: If there is contestability between the first and second-largest shareholders, the strength of the catering effect of the dividend is greater than in the case of collusion, both in the years of positive and negative dividend premiums.\u0000Methods: The main research method is a panel regression model (pooled OLS and fixed effects). We use the F test, the Breusch-Pagan test, and the Hausman test. Our research is supplemented with descriptive statistics and the Pearson correlation coefficient. The research sample consists of Polish companies from the electromechanical industry sector listed on the main market of the Warsaw Stock Exchange (WSE) in the years 2009?2020.\u0000Findings & value added: The main findings are as follows: a) if a dividend premium is positive and the second-largest shareholder holds many shares, the strong catering effect of dividends is observed; b) there are only two years of negative premium, which does not allow to conclude that both the catering effect and the impact of interactions between the largest shareholders on dividend payouts do not exist when dividend premium is negative. We propose pioneering research concerning the catering effect in the context of interactions between the largest shareholders. Its long-term theoretical value added is the original and interdisciplinary research combining financial, behavioral and governance aspects. Our research results may be of particular interest to foreign investors looking for new opportunities to invest their capital abroad, also in Poland.","PeriodicalId":84667,"journal":{"name":"Equilibrium","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49650345","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 industry consolidation and many acquisitions led to a reduced number of breweries and consequently to the homogenization of beer. It was an important factor affecting the significant decline in beer consumption in the world. However, over the years, this negative phenomenon also brought a new wave ? the development of craft breweries, and resulted in the formation of a new segment with specific preferences in the market.\u0000Purpose of the article: As a result of the craft beer revolution in the world and the wider offer on the beer market, customer preferences changed, and a new segment was subsequently formatted. In the past, lagers were the preferred choice, but due to the new wider range of beers offered in the market, they are about to lean towards other types of beer. Therefore, the purpose of this paper is to identify a new segment of craft beer consumers based on characteristics such as age, gender, education, income, residence, marital status, work, and leisure activities.\u0000Methods: For data collection, a questionnaire was used as a tool and, therefore, we analyzed the answers of 685 respondents from Slovakia. The questionnaire is evaluated through dependency analysis using nonparametric methods (Kruskal-Wallis Test, Mann-Whitney Test) to identify the differences between groups of customers and to describe the characteristics of a typical consumer of craft beer.\u0000Findings & value added: The craft beer revolution in the world brought a formation of a new segment, which considers the taste and quality more compared to price. Our research has confirmed that this segment consists of highly educated men (26?40 years old), with above average income. However, it is important for beer producers to know this segment more to meet its requirements. Nevertheless, deeper studies of this segment were missing. Therefore, our research was focused on other parameters of the segment and according to our findings, these consumers are from bigger cities, working more mentally, and doing sports in leisure time.","PeriodicalId":84667,"journal":{"name":"Equilibrium","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46298621","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 problem of increasing income inequality is currently a challenge for the EU economies, not only with well-established liberal traditions, but also with conservative and social-democratic ones. Therefore, it is worth conducting research on the redistributive effects of fiscal policy.\u0000Purpose of the article: The article aims to show the redistributive effects of fiscal policy, paying particular attention to the most characteristic trends in redistribution, which are responsible for the growing income inequality. An overview of the fiscal instruments ? mainly personal income tax and benefit systems ? along with an empirical research on their potential impact on income inequality, allows for conclusions to be drawn about the effectiveness of redistributive policy in the EU countries.\u0000Methods: Both descriptive analysis and panel data analysis is implemented to examine the effectiveness of redistributive policy in tackling income inequality in the EU?28 countries in years 2005?2017.\u0000Findings & value added: Based on the panel analysis, it has been found that social transfers were much more effective than direct taxes in combating income inequality. In addition, the largest increase in income inequality ? as previously assumed ? was observed in the liberal welfare states, while the smallest in the social democratic welfare states.

It is reflected in the industry structure of the region, formed in the process of its historical development. The industry structure is the basis for the development of regional specialisations. One of the criteria for defining specialisations is the employment structure by sections and divisions of the national economy. The definition of regional specialisations is indispensable for planning the development policy and for formulating regional strategies.\u0000Purpose of the article: The main objective of the paper is the analysis and evaluation of employment structure as a criterion for the delimitation of industries identified as smart specialisations in the region. The study covers the case of selected region in Poland at NUTS-2 level ? the voivodeship of Małopolska. \u0000Methods: The study is based on GUS unpublished data (Statistics Poland) for 2009 and 2018. It makes use of descriptive statistical analysis methods and structure and dynamics ratios, as well as Florence?s specialisation coefficient.\u0000Findings & value added: The research has shown that the employment structure indicating the presence of the region's specialisation in given industries is an important, but not sufficient criterion for the evaluation, whether the delimitation of industries recognized as smart specialisations was appropriate. In the light of the conducted research, it seems fully justified to grant the status of smart specialisation in Małopolska to Information and Communication Technologies as well as to Creative and Leisure Industries. In the context of changes to employment dynamics and structures, the possible development-oriented smart specialisations are as follows: Manufacture of metals and metal products, Electronics and machine industry, and Chemistry. On the other hand, the identified specialisations: Life science and Sustainable energy are not in line with changes in the region?s employment structure. The paper proposes one of the possible ways of precise identification of distinctive regional industries with high development potential. The structure of employment and changes occurring in this area make it possible to determine the main forces of the region's endogenous potential, and thus may form the basis for the determination, and in the longer term, assessment of the relevance of identified regional smart specialisations. The added value of the study is, therefore, an attempt to assess, on the example of a selected region, to what extent changes in regional specialisations reflected in the existing employment structure confirm the accuracy of the selection of industries identified as regional smart specialisations. The presented case is an exemplification of the proposed method, which can also be successfully applied to other European regions.","PeriodicalId":84667,"journal":{"name":"Equilibrium","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43120679","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}
