Millennials are currently taking over the global workforce. While practitioners and scholars have recognized their different work values from previous generations, research on this topic is still scarce. Furthermore, the current leadership theories have tended to focus mainly on the characteristics of leaders without adequately examining the leadership styles that work best for the millennials. Using a literature review from the top tier leadership journals, this paper aims to provide a more comprehensive framework to provide new directions for the development of leadership theory by  understanding the millennials’ perspective on leadership. This study thus contributes to the current literatures by using five thematic leadership groups to develop the most optimum leadership style for leading the Millennials. The advantages and disadvantages of using neo-charismatics, leadership and information processing, social exchange/relational leadership, ethical/moral leadership, and e-leadership theories in leading millennials are assessed. Results show that no single leadership theory is adequate for leading the millennials optimally. Hence, mixing the dimensions of different leadership theory groups is suggested. As for the leadership theory aspects, it is recommended to scholars to consider developing more flexible leadership theory models that can accommodate different generational groups.

This paper aims to measure the impact of COVID‐19 and changes in economic policy uncertainty (EPU) on the US stock market volatility using Event Study, Stepwise Regression, and Vector Autoregression (VAR) models. The impact has been examined under three contexts namely inside the US, outside the US and the whole world. This study finds negative cumulative abnormal returns of the market in response to the announcement of new cases and death records whereas the market reacts positively to the announcement of the financial bailout. The negative and significant impact of reported deaths and cases on the volatility of stock indices indicates that the US stock market is highly sensitive to the COVID‐19. EPU has a significant and positive impact on the volatility of the US stock market. The COVID‐19, EPU, and volatility variables are cointegrated and move in a unidirectional way. This study considers the presence of a long‐run relationship among the variables and concludes that the US stock market is more exposed to COVID‐19 compared with the rest of the world.

Despite their increasing ubiquity in people's lives and incredible advantages in instantly interacting with others, social media's impact on subjective well-being is a source of concern worldwide and calls for up-to-date investigations of the role social media plays in mental health. Much research has discovered how habitual social media use may lead to addiction and negatively affect adolescents' school performance, social behavior, and interpersonal relationships. The present study was conducted to review the extant literature in the domain of social media and analyze global research productivity during 2013–2022. Bibliometric analysis was conducted on 501 articles that were extracted from the Scopus database using the keywords social media addiction and problematic social media use. The data were then uploaded to VOSviewer software to analyze citations, co-citations, and keyword co-occurrences. Volume, growth trajectory, geographic distribution of the literature, influential authors, intellectual structure of the literature, and the most prolific publishing sources were analyzed. The bibliometric analysis presented in this paper shows that the US, the UK, and Turkey accounted for 47% of the publications in this field. Most of the studies used quantitative methods in analyzing data and therefore aimed at testing relationships between variables. In addition, the findings in this study show that most analysis were cross-sectional. Studies were performed on undergraduate students between the ages of 19–25 on the use of two social media platforms: Facebook and Instagram. Limitations as well as research directions for future studies are also discussed.
