Electronic marketing (eM) is a flourishing phenomenon that is gaining intense concern because of a significant impact on organizational performance. Over the past few decades, the relevance of eM has been observed in numerous fields (e.g., consumers, organizational strategy, advertisement, and overall philosophy of management to understand the insights globally). To effectively maneuver the field, all stakeholders, particularly academicians and practitioners, must comprehend the current position of the eM theory and practices for dynamic utilization. A systematic bibliometric analysis can serve this issue by providing a holistic view of the publication trend and its trajectory in terms of various themes, including citations and publication metrics. This study analyzes the bibliometric data from 2000 to 2019 to reveal the most productive countries, universities, authors, journals, and prolific publications in electronic marketing. To this end, VOS viewer software was used to visualize the mapping based on co-citation, bibliographic coupling (BC), and co-occurrence (CC). The primary addition of this research is to provide an overview of eM tendencies and paths that may help researchers know the tendencies and future research directions worldwide.

Environmental deregulation has become a severe concern for public health around the world. Increased pollution and ecological degradation have diverted attention towards adopting green practices, which can be possible if the sustainable green finance system is implemented in its true spirit. But previous studies reported certain factors affecting its implementation process, particularly in developing countries. This study aims to identify and quantify the barriers to adopting a green finance system. First, it identified twenty barriers through an extensive literature review and semi-structured interviews with experts in the fields of financial management, economics, and environmental sciences. Later, eighteen factors were finalized by the consensus of panel experts, which was further used to analyze their interrelationship through Interpretive Structural Modelling (ISM). Using MICMAC analysis, these barriers were categorized based on their diving-dependence powers. Finally, the conceptual ISM model is developed that provides a clear picture of the impediments to the green finance adoption system and their flow relationship among the identified barriers at different levels. The findings suggest that global level factors: lack of pressure from international organizations and unavailability of globally acceptable green criteria are critical to the prevalence of other factors that indicate its centrality to effectively implementing the green finance system. The developed model helps in designing, implementing, and promoting eco-friendly projects. It is also recommended that an appropriate framework is required to be developed at global, country, organizational, and individual levels to deal with the barriers of the green finance adoption system.

The purpose of this research paper is to explore the antecedents and consequences of circular entrepreneurship in emerging markets. The consequences of circular entrepreneurship will be explored through the lens of three dimensions of sustainability: social, economic, and environmental. This study used a multi-case approach, which is frequently applied in circular business literature. The study used convenient and purposeful sampling techniques to identify circular entrepreneurs starting a business by recognizing opportunities in CE. We interviewed the 15 entrepreneurs (all participants engage in plastic circular entrepreneurship) with more than 8 years of experience. We employed a semi-structured interview method because respondents explored important information during the interview. Atlas.ti, a prominent qualitative software package, was used for analysis. This study portrays the antecedents and consequences of circular entrepreneurship identified when circular entrepreneurs take the initiative to serve low-income customers. This study points out that circular entrepreneurs can be motivated both intrinsically and extrinsically. The consequences of circular entrepreneurship show how such enterprises impact on society, sustainability, and the economy. The study points out that circular entrepreneurship can have both positive and negative impacts on the environment. By investigating the determinants and consequences of circular entrepreneurship in emerging markets, the authors make a significant contribution to the field of circular economy and entrepreneurship. We have limited logistics and resources, thus we did not collect data from stakeholders, who might provide a richer picture and insights into how circular products affect their lifestyle. Policymakers can get a better understanding of such enterprises from the findings of this study. They should reassess policies regarding circular entrepreneurship and suggest ways to promote open innovation within circular entrepreneurship. Circular enterprises serve low-income customers by offering an affordable product with attractive features. The government should develop an open innovation action-packed forum to find, design, and create prototypes, as well as introduce more comprehensive sustainable solutions for wastable plastic products.

The trend of using social media in the workplace is now becoming ubiquitous. Along witbenefits, social media also has negative consequences. Employees use social media for both work and social purposes. Therefore, using a quantitative approach, this study explores the impact of work-related social media usage and social-related social media usage on employees’ work performance. This study also investigates the mediating effect of extra-role behaviors on social media usage (professional and personal purpose) and work performance relationships. We examined survey data of 241 employees working in different organizations with the help of the partial least square (PLS) 3.0 version. Convenience sampling has been used to reach respondents. The outcomes of this study demonstrate that both professional and personal-related social media usage have a positive and significant impact on employees’ work performance. This study also highlighted that extra-role behavior positively and significantly mediates the relationship between social media usage (work and personal) and employees’ work performance. This study provides practical insights to managers, such as that, instead of banning social media usage in companies, there must be some limits and regulations for using social media that would facilitate firms to increase employees’ engagement and productivity.

Sub-Saharan African countries are known to be bedeviled with some challenges hindering the economic development. Meanwhile, some of these issues have not been exhaustively investigated in the context of the region. Thus, this study aimed at investigating the implications of government effectiveness, availability of natural resources, and security threats on the regions’ economic development. Yearly data, spanning from 2007 to 2020, was converted from low frequency (yearly) to high frequency (quarterly) and utilized. Data analysis was conducted using Dynamic heterogeneous panel level estimators (PMG and CS-ARDL). Findings show that while PMG estimator confirms a long-run causal effect of governance, natural resources, and security threats on economic development, only natural resources show a short-run causal effect with economic development, while the CS-ARDL (model 2) confirms the significance of all the variables both in the long and short-run. Moreover, the ECT coefficients for both models were found to be statistically significant at less than 1% significance level, which indicates that the systems return back to equilibrium in case of a shock that causes disequilibrium, and in addition, reveals a stable long-run cointegration among the variables in the model. Finally, this study suggests that the policy makers in SSA countries should place more emphasis on improving governance, managing security challenges, and effectively utilizing rents from the natural resources, as all these have severe implications for the economic development of the region if not addressed.

The banking sector has a significant impact on a nation’s financial stability and economic development. As one of the fundamental components of the financial sector, banks offer services that are essential for the expansion of the markets. The stability of the financial system is significantly impacted by the efficiency of the banking sector. COVID-19 has had a tremendous effect on the economy. This pandemic cannot be disregarded, considering how widespread it has been and how many people it has affected globally. Both society and the global economy have undergone profound change. Hence, it is critical to ascertain how severely the outbreak has impacted the banking system. To assess the potential impact of pandemic, the current study examined conventional and Islamic banking. This study also investigates how COVID-19’s moderating effect influences the banking system. Financial statements from 10 conventional banks and 5 Islamic banks in Pakistan are the sources of this study’s sample data. COVID-19 is a moderator in this study. The empirical estimations by means of the fixed-effects approach suggests that the moderator has a large impact on bank profitability. In addition, COVID-19 appears to have a stronger influence on the Islamic banking system.
