This paper, drawing on a questionnaire survey conducted among 587 coal miners from six coal mines, seeks to ascertain whether the Polish coal mining industry is committed to organizational greening and whether its employees behave in environmentally responsible ways. Specifically, it explores—by means of hierarchical linear modeling (HLM)—the direct effects of green organizational climates on miners’ pro-environmental conduct at home and at work. We found that climates had a direct effect on employee behavior in and outside the workplace, and that personal environmental values were positively related to the latter variable. However, it has to be admitted that the actual engagement of coal miners in voluntary pro-environmental action at work was not very deep. Crucially, it turned out that, in two coal mines, there were strong green climates, while the rest were weak, which suggests differences in terms of commitment to organizational greening throughout the industry. The present paper explores the significance of the results and highlights the applicability of our methodological approach to the study of employee involvement in organizational pro-environmental action.

This article explores the concept of the ‘Trump effect’, defined by a technological disconnection and evaluated through alterations in export specialization among various economies. It scrutinizes if there were any shifts in the techno-nationalist trends of the EU, China and the US in terms of domestic value-added exports in technology sectors after 2017. The research covers the period from 1995 to 2020 and utilizes a fluctuating difference-in-differences approach. The findings suggest that technological global value chains (GVCs) were minimally affected by Trump’s policies, showing scant evidence of significant disconnection in the economies under study. Consequently, the research underscores the robustness of GVCs against the measures taken by the Trump administration.

The purpose of this paper is to provide an analytical analysis of cointegration between Europe and the other significant trading partners, namely US, China, Japan and Australia, for the period from January 1, 2010 to December 30, 2016. This captures the impact of the sovereign European debt crisis and the Greek crisis. A range of parametric techniques were adopted including Johansen cointegration analysis, Vector Error Correction Model and Granger causality. The results of the crisis Granger causality test during the European sovereign crisis implies the highest influence to be that of the US and Japanese stock market over the other four markets. Overall, found that the Asia-Pacific region plus the US stay closely related to each other, while European countries influence all the studied markets except each other. For the post-crisis sub-period, the Granger causality is slightly different. It is observable that the UK and Germany are influencing all the markets. This is probably due to the recent Brexit referendum outcome and potential consequences not only for the EU, but also for the rest of the world too. Overall, the Granger outcome shows the dependence between Europe and other global markets, but there is no European interdependence during the sovereign debt crisis period. It may be concluded that there is a separation of Asian markets from the European markets and even though cointegration exists, the relationship is rather weak.

Purpose: The purpose of this study is to find out how consumers respond to a proposed family-enterprise collective certification trademark and how they perceive family firms in general.Design/methodology/approach: The paper employs a quantitative approach. It draws on a questionnaire survey conducted among 1,091 Polish consumers in January 2018. Statistical methods, such as exploratory factor analysis, were applied.Findings: Polish consumers responded positively to the proposed trademark. It also turned out that those who pay attention to the producer or the brand owner in a given sector also pay attention to the symbols placed on products or services from these sectors. There was a strong relationship between consumers' positive perceptions of family firms and their assessments of the proposed trademark. This did not extend to negative perceptions. The findings from this study may be generalisable to other post-communist societies.Practical implications: Family firms should redouble their efforts to introduce a family-enterprise collective certification trademark (not only in Poland, but also in those countries where such a trademark is non-existent). This should be handled by umbrella bodies for family business.Originality/value: Little research work, based on a large and representative sample, has so far focussed on the issue of how consumers respond to a family-enterprise identity. The value of this study lies in deepening understanding of the processes and mechanisms that underlie the organisation–consumer relationship within the context of family-enterprise operation.

This paper focuses on the economic dimension of sustainability by examining the stock exchange interface of financial markets, the influence of capital market stakeholders, and the instruments that contribute to a supportive fiscal framework. Only mature stock exchanges are present in sustainability indices; hence, comparative assessment of stock exchanges is limited and contributes to the complexity of conducting such a study. Utilizing multivariate analysis, this study investigates the potential for African stock exchanges to support sustainability. An empirical study was conducted on a selected sample of 15 African stock exchanges at the end of 2020 using collected 5-year interval data from Q1 of 2021. A total of 22 variables were selected based on their legitimacy to support sustainability. Using exploratory factor analysis, two key sustainability drivers of differentiation and classified exchanges were identified, i.e., hard and soft. K-means classification method verified the results and found that of the four identified homogeneous groups, one—the Johannesburg Stock Exchange, Nigerian Stock Exchange, and the Egyptian Exchange—emerged on top. Two smaller groups had the potential to be strengthened, and the majority group lagged behind. The research demonstrated the importance of identifying key sustainability drivers and examined the materiality of the drivers within an African context.
