This study aims to explore the strategic integration of Sharia-compliant and environmental, social and governance (ESG)-focused investments within global equity portfolio optimization frameworks, with a particular emphasis on variance minimization and dynamic rebalancing techniques.

The research uses historical data from Sharia-compliant, ESG-focused and conventional equity exchange-traded funds (ETFs). Advanced mean-variance optimization methodologies via quadratic programming are employed, encompassing static optimization with and without a 50% cap on individual asset weights, dynamic optimization with monthly rebalancing and rolling window optimization.

Portfolios integrating Sharia-compliant investments frequently outperform those composed solely of conventional equity ETFs. Dynamic optimization with monthly rebalancing achieved the highest Sharpe ratio (1.3708) and demonstrated enhanced portfolio resilience during market turbulence, such as the COVID-19 pandemic. Sharia-compliant investments showed substantial allocations during key periods, with weights reaching up to 100% in the first half of 2020. In contrast, ESG-focused investments exhibited more limited and sporadic allocations, reflecting a more opportunistic role in the portfolio.

The findings reaffirm the critical role of Sharia-compliant investments in well-diversified, risk-conscious portfolios while also providing nuanced insights into the more selective integration of ESG-focused assets. The results offer practical guidance for portfolio managers seeking to integrate ethical and sustainable investment principles within advanced portfolio optimization frameworks, particularly when focusing on minimizing variance and dynamically responding to evolving market conditions.

The study contributes to the growing body of literature on ethical and sustainable investments, demonstrating that it is possible to balance ethical considerations with robust financial performance. The research underscores the potential for Sharia-compliant investments to play a significant role in global portfolios, potentially fostering greater financial inclusion and cross-cultural understanding in the investment community.

This research provides novel insights by focusing on Sharia-compliant investments within non-Muslim countries, an area that has been relatively underexplored. It also compares the outcomes of static, dynamic and rolling optimizations, highlighting the dynamic interplay between ethical investment principles and financial performance.

The study aims to investigate market reactions associated with the JUST 100 rankings published by JUST Capital, a non-profit organization, as well as differences in financial reporting quality and performance between selected firms and their industry peers.

This study uses a sample of 431 firms selected as the 100 America’s Most Just Companies between 2016 and 2020 by JUST Capital. This study performs both an event study to determine whether the rankings are useful to investors and cross-sectional regression analyses on the characteristics of selected firms compared to their peers.

This study finds that investors react positively to selected firms around the time of the release of the JUST 100 rankings, suggesting that the rankings are decision-useful. This study also finds that selected firms exhibit higher accounting quality and financial performance than their peers.

Rankings may not be free from bias because of JUST Capital’s ownership of an exchange-traded fund.

The findings validate the rankings as well as the methodology used by JUST Capital, as they show market participants value firms that engage in socially responsible actions through their commitment to positively impact five key stakeholder groups: employees, customers, communities, environment and shareholders.

To the best of the authors’ knowledge, this is the first study that shows the importance of the JUST 100 rankings for investment decisions. Considering the growing push for companies to disclose environmental, social and governance (ESG) activities, this study provides evidence to support ESG disclosure regulations.

Perception of organizational politics is one of the key factors of the organization's performance. Based on the principles of Game Theory, this study aims to examine the impact of management's and employee's politics within an organization on the psychological and organizational stress levels of workers, followed by their task and contextual performance.

Following the non-probability convenience sampling technique, the data was collected from the managerial and non-managerial staff of public, private and semi-government services organizations in Rawalpindi, Islamabad, Lahore, Faisalabad, Gujranwala, Abbottabad and Karachi cities in Pakistan.

The structural analyses indicate that organizational politics is a major cause of stress among workers and has a significant positive impact on the psychological and organizational stress of workers. Moreover, both organizational politics and job stress hinder workers' performance.

The findings of the current research provide valuable insights into the management of firms about the destructive role of politics with a special focus on psychological and organizational stress, followed by job and contextual performance, particularly in the context of Pakistan. It also proposes strategies to counter this issue, improving worker's performance. Furthermore, the findings also suggest whether management or employees are more involved in organizational politics.

The purpose of this research is to reveal the impact of public legal protection on the efficiency of internal corporate governance in banks. In addition, this research proposes a new corporate governance index that could be employed by the banking sector to evaluate the performance of their internal corporate governance mechanisms.

Orbis database, annual reports and direct questionnaire are used to collect corporate governance data of 127 banks from 14 countries during 2020. The Mann–Whitney U-test is employed to compare the efficiency of corporate governance mechanisms based on three subsamples of countries having different legal protection levels (weak, middle and strong).

This research suggests a new corporate governance index for banks based on seven constructs and 62 variables. This new non-parametric index could be used by bankers to improve the monitoring process and enhance the overall performance of banking. The results of this research show that the existence of a strong public legal protection environment within a specific country enhances the efficiency of corporate governance mechanisms in the banking sector and thus, leads to improve the protection of shareholders, depositors and other relevant stakeholders. However, in countries that are characterized by weak legal protection level, the efficiency of corporate governance mechanisms is very low and there are possibilities of entrenchment, expropriation and extraction of private benefits. These findings could be interpreted within the prediction of agency, moral hazard, asymmetric information, political and entrenchment theories.

This research paper provides information that bankers and other relevant stakeholders in the banking sector working in MENA (the Middle East and North Africa) and European countries. A strong public legal protection level could improve the efficiency of internal corporate governance mechanisms within banks.

Recent advances in stochastic frontier analysis (SFA) suggest two alternative approaches to account for unobserved heterogeneity and to distinguish between persistent and transient inefficiency. The first approach is the generalized true random effects (GTRE) model, and the second approach is an autoregressive inefficiency (ARI) model. This study compares them to highlight whether they capture similar inefficiency aspects.

Using recent methodological advances in SFA, the authors estimate the GTRE and the ARI models using a Monte Carlo experiment and two real datasets from two industries (banking and agriculture).

The authors find that the two models provide quite different results in terms of inefficiency persistence and overall inefficiency (combination of transient and persistent inefficiency), regardless of the dataset considered.

The study findings suggest that researchers should be careful when referring to these two models because they do not capture the same inefficiency aspects, even though they have the same conceptual basis. This work is a warning about the empirical aspects of the persistent and transient efficiency framework, in order to convey a consistent story to the reader on firms' performance.

Even though they are used in a large number of studies, the present paper contributes to the productivity and efficiency literature by providing the first comparison of the GTRE and the ARI models.

This paper proposes a new multi-dimensional financial inclusion index.

The authors employ two-stage principal component analysis (PCA) and aggregating indicators of availability, access and use. The paper first assesses the cross-country variations in the index and analyses trends over time for a sample of countries members of the Union for the Mediterranean (UfM) from 2010–2018. Second, it investigates factors that could explain the level of financial inclusion across countries.

The financial inclusion index shows a downward trend for the full sample over the period under investigation; however when splitting the sample by income group, it appears that high- and middle–income countries did not register the same trend. When examining the determinants of financial inclusion for the UfM countries, the authors find that macroeconomic, social and governance factors, as well as banking conditions, matter. Policy-makers in low- and middle-income economies should consider the importance of digital financial inclusion, which is substituting the role to traditional banking system, to close the gap and accelerate its development.

First, the authors provide a new measure of financial inclusion using a three-dimensional index: availability, access and use, for which weights are assigned using PCA. It uses data available for the UfM sample by combining data from different databases in order to include most indicators considered in the literature, as the majority of studies only use single measures (number of bank branches, ownership of a bank account, ratio of credits or deposits to gross domestic product [GDP], etc.). Second, by focussing on UfM countries, the study covers a region that includes both large developed and small developing economies that are connected via financial and trade ties, whilst previous studies generally give global evidence from an international sample with little or no economic ties. Third, splitting the sample by country income groups, the paper presents a more comprehensive representation of the cross-country variation in financial inclusion levels between high- and middle-income economies for this region.

This paper aims at shedding light on the entrepreneurs' perception towards crowdfunding as a new mean for raising capital, and their willingness to send appropriate signals to the potential fund providers/backers.

The research strategy is based on three methodological approaches: desk research on online sources, a map of the crowdfunding phenomenon, and a quantitative approach with a survey performed between June and December 2020. The survey covers a sample of 147 Small and Medium enterprises (SMEs) and startups, in addition to semi-structured interviews with 10 entrepreneurs.

The study reveals that between losing their work and losing part of their firms' equity, entrepreneurs are keen on sending positive signals to backers. Moreover, they are willing to adopt a new way of thinking, as their primary goal is to save their firms, their jobs, and their source of income. The research highlights the concern of entrepreneurs of losing reputation, losing intellectual property, losing control, and of becoming only shareholders in their enterprises.

The main limitation in this paper is that no single study in Lebanon adequately covers the topic and thus extensive research has been carried out on crowdfunding across the world and analyzed in the Lebanese context.

Overcoming funding challenges can reduce brain drain, promote a culture of entrepreneurship, serve the economy, combat poverty, achieve more equitable society, increase the levels of expectations, and turn the flywheel. Moreover, the paper presents clear implications for the field of policy-making both in developing and developed countries.

Considering the serious financial disintermediation and liquidity shortage Lebanon faces, the findings of this study show how important changing entrepreneurial culture and behavior is, and the crucial role crowdfunding could play in providing funds for the SMEs that form 95% of the total business sector in Lebanon.

This study proposes a new comprehensive model of entrepreneurial intentions (EIs) that enhances the understanding of the crucial entrepreneurial personality traits. This study also examines how entrepreneurial family history, gender and discipline moderate the relationship between the key entrepreneurial personality traits and EIs of university students.

The study introduces a new combination of important entrepreneurial personality traits, theoretically following the theory of planned behaviour (TPB). The data are collected using an entrepreneurial intention questionnaire and analysed with structural equation modelling (SEM) over a sample of 297 university students from Pakistan.

The findings highlight that one of the notable contributions to assessing EI is the negative impact of foreseeable challenges (FCs), resulting in negative EIs among university students of our sample. The authors also found significant moderating roles of gender, discipline and entrepreneurial family history in strengthening the relationship between entrepreneurial traits and EIs.

The study contributes both to the existing empirical and theoretical literature by examining a key set of entrepreneurial personality traits leading to enhance EIs. The results may also assist academicians to discover new ways for developing entrepreneurial traits among university students.

This paper aims to examine the different types of communication mechanisms in motivating the use of halal-based apps among Brunei Muslim students in higher education institutions abroad.

Using a convenience sampling procedure, 100 online structured questionnaires were accumulated from various higher education institutions abroad with a 60% response rate from Brunei Muslim students. Descriptive analysis, Binomial Logit and the Binomial Probit model were used to test different types of communication mechanisms in motivating the use of halal-based apps among Brunei Muslim students studying abroad. Demographic profiling such as gender, age, university programs and length of the program was also considered in the study.

Based on the statistical analyses, the word-of-mouth (WOM) mechanism is significant and more effective in influencing halal-based app usage among Muslim students abroad. Moreover, halal-based app usage with the combination of WOM mechanism and social media platform play a vital role in spreading halal awareness.

The sample was taken from random higher educational institutions abroad and respondents were selected using convenience sampling. Therefore, it may not be fully representative of the population of Brunei Muslim university students studying abroad. Second, there may also be missing variables that have not been considered in the study.

This study generates important insights from Muslim consumers on halal-based app usage. Stakeholders can integrate halal-based apps with digital word-of-mouth and social media interfaces to promote halal awareness and halal-based app usage effectively.

This research adds to the current limited knowledge of halal-based app usage among Brunei Muslim university students abroad.
