This paper aims to examine how the diversity of educational levels within bank boards influences the efficiency and stability of banks operating in the Middle East and North Africa (MENA) region. Unlike previous studies, this analysis also investigates the role of board gender diversity in moderating the relationship between board educational level diversity and bank efficiency and financial stability in MENA.

In this study, a sample of 77 banks in the MENA region spanning the years 2011 to 2018 is used. The relationship between the presence of highly educated directors on the board, bank efficiency and stability is assessed using the ordinary least squares method. Additionally, the authors use the Generalized Method of Moments technique to correct endogeneity problem.

This study establishes a positive association between the presence of directors with advanced educational backgrounds on bank boards and bank efficiency and stability. Furthermore, the inclusion of women on the board strengthens this relationship.

These findings have important implications for policymakers and regulators in the MENA region, suggesting that promoting diversity policies that encourage the participation of highly educated directors on bank boards can contribute to enhanced efficiency and financial stability. Policymakers may also consider implementing quotas or guidelines to improve gender diversity in board appointments, thereby fostering bank performance in the region.

This study stands out for its innovation and distinctiveness, as it delves into the connection between board educational level diversity and bank efficiency in the MENA region. Notably, it surpasses previous research by investigating the moderating role of board gender diversity, thus offering valuable insights into the complex interplay between these two facets of board diversity. This contribution enriches the existing literature by providing novel perspectives on board composition dynamics and its influence on bank efficiency and stability.

This study aims to explore the effects of expertise diversity on project efficiency and creativity in health-care project teams.

This study analyzes hierarchical linear models using multi-source data from 50 project teams in a large health-care organization in the USA. This data set includes self-reported survey responses from 274 team members and human resource information for all 515 members across the 50 teams. Expertise diversity is operationalized by professional diversity and positional diversity reflecting two dimensions, domain and level, of the concept of expertise.

This study reveals that professional diversity is negatively related to project efficiency and project creativity, whereas positional diversity is positively related to project efficiency.

Successfully managing a project team of experts within a limited time frame is a challenge for organizations. This study advances the understanding of the double-edged sword effect of expertise diversity on project teams, focusing on professional and positional diversity. It provides important insights for human resource development in terms of the composition of project teams regarding members’ expertise.

The purpose of this study is to explore the link between aggregate production efficiency and the extent of linguistic clustering in Indonesia.

The author draws on the stochastic frontier model and applies it to the data on Indonesian provinces to compute the effects of various determinants on these provinces' aggregate production efficiency. The key determinant is the spatial index of linguistic clustering that the author believes has never been applied before in this context.

Linguistic clustering is an important determinant of aggregate production efficiency. Linguistic diversity is positively associated with productive efficiency if members of a specific linguistic group are not clustered beyond a certain level.

To the best of the author’s knowledge, this is the first study that links the spatial index of linguistic clustering (because of Massey and Danton) to production efficiency. In other words, the contribution of this study is to introduce a geographical dimension to the mainstream analysis of the association between ethnic diversity and economic performance.

This paper aims to explore whether environmental, social and governance (ESG) performance is positively associated with firm investment efficiency (IE) in emerging economies. It also examines whether board cultural diversity can moderate the ESG–IE relationship.

This paper uses a cross-country sample of listed firms located in seven emerging countries over the 2011–2019 period. The authors use a fixed effect panel regression to empirically test the hypotheses. The authors also use a lagged model and a Heckman’s (1979) two-stage procedure to mitigate potential endogeneity issues. In addition, a two-stage least squares regression analysis was done as an additional robustness check.

This study finds that firms with stronger ESG performance have a higher investment efficiency. Interestingly, this study finds that board cultural diversity negatively moderates the impact of ESG performance on IE for firms operating in settings prone to overinvestment. This result suggests that ESG performance plays a less important role in mitigating managers' tendencies to overinvest when corporate boards have more foreign directors. However, the authors do not find such evidence in firms prone to underinvestment. These findings hold after using an alternative measure of IE and controlling for endogeneity concerns.

This paper adds to the existing body of knowledge in three dimensions. First, to the best of the authors’ knowledge, this is the first cross-country study that investigates the linkage between ESG performance and corporate IE in the context of emerging countries. Second, the authors have enriched the prior literature by examining the moderating effect of board cultural diversity on the positive association between ESG performance and corporate IE. Finally, this study has important implications for policymakers and capital suppliers in emerging countries, which strive to facilitate the efficient allocation of scarce resources.

Previous literature posits that corporate governance and information asymmetry are the main factors in making efficient investments. Meanwhile, a growing body of studies is of the opinion that corporate governance can also mitigate the problem of information asymmetry and consequently exerts significant impacts on the association between information asymmetry and investment efficiency. This study aims to analyze the impact of corporate governance and information asymmetry on investment efficiency. It also tests the moderating role of corporate governance in the relationship between information asymmetry and investment efficiency.

The sample consists of 4,082 firms domiciled in 20 developed countries over the years from 2003 to 2019, including 33,812 firm-year observations. The bid–ask spread is used as a proxy for information asymmetry. To measure corporate governance performance, a proxy provided by ASSET4 is employed, and to determine the optimal levels of investments, we relied on the growth opportunity. To estimate the models, ordinary least squares and generalized method of moment are used.

The results reveal that information asymmetry is inversely related to investment efficiency, and, corporate governance mitigates this negative association.

This paper sheds light on the role of corporate governance in firms as a lever for mitigating information asymmetry and tries out information asymmetry and agency theories in relation to the impact of information asymmetry on investment efficiency. It also confirms the theory stating that corporate governance can be considered as a determinant of investment efficiency.

Using the American and the French time-use surveys, we examine whether people have a preference for a more diversified mix of activities, in the sense that they experience greater well-being when their time schedule contains many different activities rather than is concentrated on a very small number. This could be due to decreasing marginal utility, as is assumed for goods consumption, if each episode of time is conceived as yielding a certain level of utility per se. With returns to specialization, people would then face a trade-off between efficiency and diversity in choosing how to allocate time. We examine these issues and investigate potential gender differences, considering both instantaneous feelings and life satisfaction.

This study aims to the development of the scale of supply chain performance measures (SCPMs), food supply chain resilience (FSCS) and sustainable corporate performance (SCP) in small- and medium-sized enterprises (SMEs) in an emerging market. Based on this purpose, the study examines the relationships between SCPMs and SCP by exploring the mediating role of FSCS in emerging markets.

Based on a comprehensive literature review on the SCPMs, FSCS and SCP, the author evaluates the nexus of these constructs on disruptions during the COVID-19 pandemic emergency in an emerging market. The article follows a quantitative approach. A total of 567 valid responses from managers at senior and middle levels were received and used for data analysis. The Smart PLS version 3.3.2 was employed to analyse Structural Equation Modelling (SEM) to investigate the relationships between constructs and latent variables.

This study provides some theoretical contributions to expand the extant literature on the domain of SCPMs. First, the findings determine that multidimensional measures of flexibility, diversity, agility, inventory efficiency, redundancy and robustness are appropriate for measuring food SC performance in disruptions during the COVID-19 emergency. Besides, this study enriches the existing literature on SC disruption by providing extensive empirical evidence on SCPMs in disruptions during the COVID-19 emergency. Finally, this research provides an integrated empirical model that explores the link between the identified food SCPMs to FSCS and SCP.

The contributions may be of interest to business practitioners, business leaders and academics. In addition, this study provides empirical evidence to demonstrate that food SC performance, as measured by these measures, is strongly related to the firm's food supply chain resilience. This is the novel contribution of this study to the current literature on food SC management. Furthermore, this study provides further empirical evidence demonstrating the partial mediating role of the firm's food supply chain resilience in the nexus between food SC performance and SCP. The unique contribution of this study is an extension of the body of knowledge of SC management literature from a comprehensive approach by providing a proven set of performance measures of SC management to which it can drive SC resilience and SCP for food manufacturing SMEs in an emerging economy that hardly found in the current literature.

This paper aims to shed light on an essential role that “female directors” on boards of companies in sub-Saharan Africa play towards corporate financial performance enhancement. The study observes how board gender diversity moderates the relationship between earnings management (EM) and financial performance of firms in sub-Saharan Africa from a dynamic perspective.

The study’s sample comprises 105 companies listed on the respective stock markets of nine sub-Saharan African countries. The data are collected from annual reports over the period 2007–2019, a total of 1,166 firm-year observations. Panel data models are used in the analyses.

The study finds that the performance effect of EM is contingent on board diversity and this finding persists even after controlling for dynamic endogeneity, simultaneity and unobserved time-invariant heterogeneity inherent in the EM and performance relationship.

The findings should be understood within the context that, only available annual reports and audited financial statements that were filed with respective capital markets of the nine surveyed countries are used as source of information.

The current study is unique, in that, it is the first panel multi-cross-country investigation within Africa to introduce gender diversity in the study of the relationship between EM and firm performance. It therefore extends the agency theory by using gender diversity as a moderating variable in the EM–firm performance nexus.

The paper aims to craft a non-parametric composite value for the board quality of Indian banks where the weights can be assigned endogenously.

The study employed a non-parametric data envelopment analysis (DEA)-based novel extension known as the benefit of doubt approach. To measure the strength of the Indian bank corporate board in terms of board efficiency (BEF), the study used a mixed approach, i.e. first, the study calculates the percentile ranks of the five attributes that the study assumes are the characteristics of the strong board including board size, number of outside directors, frequency of meetings, non-duality leadership and board gender diversity. Thereafter, the study performs the benefit-to-doubt approach to finally measure the efficiency of the board.

The findings of the study establish that the methodological framework present in the study to measure the strength of the board in terms of BEF has been a much superior method over the other weighted and non-weighted linear average methods.

This methodology aids the shareholders, investors and regulatory bodies in rating the Indian banks based on their strength in terms of better monitoring boards and ensuring a smooth agent–owner relationship.

The benefit of doubt approach has been a unique and novel methodology to craft the composite value for any multidimensional phenomenon. One of the major benefits of using this approach is that it assigns the weights endogenously to each dimension and thereafter collectively determines the efficiency of such a phenomenon.

The article aims to investigate how washing practices focused on appeasing sceptics of diversity work in for-profit organizations play out in corporate online communication of diversity and inclusion efforts, and how these enable communication to a wide audience that includes social equity advocates.

Online corporate communication data of diversity and inclusion themes were compiled from the websites of eight Swedish-based multinational corporations. The data included content from the companies’ official websites and annual reports and sustainability reports as well as diversity and inclusion-themed blog posts. A thematic analysis was conducted on the website content.

The study showcases how tensions between conflicting external demands are navigated by keeping the communication open to several interpretations and thereby achieving multivocality. In the studied corporate texts on diversity and inclusion, this is achieved by alternating between elements catering to a business case audience and those that appeal to a social justice audience, with some procedures managing to appease both audiences at the same time.

The article complements previously described forms of washing by introducing an additional type of washing – business case washing – an articulation of the business case rhetoric that characterizes the diversity management discourse. While much has been written about washing to satisfy advocates of social change and equity, washing to appease shareholders and boardroom members, who are focused on profit and economic growth, has received less attention. The article suggests that online corporate communication on diversity and inclusion, by appeasing diverse audiences, can be seen as aspirational talk.
