This study aims to quantify the cost of rebalancing Sharīʿah-compliant indexes, both economically and statistically.

An empirical approach is employed where the rebalanced Sharīʿah-compliant index is calculated numerous times with different lags in rebalancing, and the number of stocks and their cost across time are determined in order to identify the optimal rebalancing frequency.

This paper finds that annual Sharīʿah rebalancing does not lead to significant differences in portfolio returns, even though it does bring some advantages in cumulative wealth starting from the third year onwards and brings about better risk-return characteristics measured in terms of the Sharpe ratio. However, these advantages involve an average annual shifting between 30 and 60% of the portfolio market capitalization, which would be costly at any level of transaction costs.

A private investor may be better off holding a constant portfolio and only rebalancing in three-year intervals since this was shown to possess similar portfolio returns and cumulative wealth results. Any advantages of annual rebalancing in terms of risk-return characteristics may be offset by transaction costs of rebalancing. Sharīʿah scholars and practitioners are to determine when the correct time for rebalancing really is, taking into consideration the cost of rebalancing vis-à-vis the advantages in cumulative wealth and risk-return characteristics of the portfolio.

Predictions that Islamic indexes will perform well during financial crises, such as the COVID-19 pandemic, miss the cost of frequent rebalancing. This paper addresses this issue in an empirical manner learning from the previous crisis in 2008.

The purpose of this study is to investigate whether ethnic discrimination is present in the Russian labor market and whether it has a significant economic effect on the potential salaries of applicants.

Data were collected using a correspondence audit for four experimental male applicants with identical professional and personal characteristics while differing only in applicant name as a signal of applicants' ethnic background. Implied ethnicities include Russians, Armenians, Jews and North Caucasians. Résumés were sent out to 800 real unique vacancies on behalf of the experimental applicants with a geographic focus on the capital Moscow.

The results of the analysis suggest that there is a significant difference in treatment in both response rate and potential average salaries on ethnic grounds. Disadvantaged groups were found to be systematically pushed into jobs paying 15% less monthly wage.

The study investigates the existence of ethnic discrimination in the Russian labor market and furthermore economically quantifies the effects of discrimination.

This study aims to explore and analyze the issues in weightages-based profit distribution mechanism in Islamic banks from Shari’ah, practical and regulatory perspectives.

A qualitative research approach was used in this study based on primary data collected through semi-structured interviews from Shari’ah practitioners and senior industry experts in the field of pool management in the Islamic Financial Services Industry of Pakistan.

The current study found that the weightages-based mechanism conforms to the rules of Mudarabah and; therefore, permissible. However, the elements of exploitation, transparency and fairness require further research, as these elements seem to exist in this mechanism. It was also found that there are many loopholes in the regulatory guidelines for pool management in Islamic banking institutions (IBIs) in Pakistan resulting in practical issues.

The findings of this study may help improve pool management in IBIs, which in turn may cater the objections raised by academicians, customers and industry experts. Moreover, the alternative solution based on the findings of this study can be transformed into a proposal for regulators to take necessary actions against unfair profit distribution and issue further improved guidelines for IBIs in Pakistan.

To the best of the authors’ knowledge, very limited studies have been conducted on pool management particularly with issues from different perspectives and alternative solutions have been suggested that may act as a proposal for IBIs as well as regulatory authorities.

The purpose of this study is to investigate the two components of market discipline, investment account holder (IAH) monitoring and the consequent reaction of the Islamic banks in GCC countries for the 2004–2013 period, including the recent financial crisis of 2008.

We address the research question that Investment Account holders (IAH) in GCC countries suc as Kingdom of Saudi Arabia (KSA), Bahrain and United Arab Emirates (UAE) monitor their banks. Regression analysis was used to examine the dependence level of profit-sharing investment account (PSIA) growth rate on bank risk characteristics (CAMEL variables). Then, the reaction of banks by regression influencing CAMEL variables of one-lagged period on PSIA growth rate was verified.

The results provide evidence of the first component of market discipline, i.e. the IAH monitoring, in KSA, Bahrain and UAE. The common result to the three countries is that market actors are concerned with accounting information on capital adequacy. However, in UAE, they are also interested in assets performance, whereas they look more at earnings in Bahrain. The results show evidence of the second component in Bahrain; the bank reaction to IAH monitoring and subsequently IAH discipline in Bahrain. Finally, the results do not support any impact of the financial crisis.

The sample size is small although it is constituted by banks having a sufficient number of observations.

This study highlights the importance of IAH discipline, which would help prudential bank monitoring by regulators and wealth development for both investors and managers. It should increase the disclosure of relevant information as for the part of effective accountability of Islamic banks’ governance.

This study contributes to the literature on market discipline by dealing with Islamic banks. It is one of the very few studies to investigate IAH discipline in Islamic banks and the second component of market discipline, i.e. the influence of monitoring on banks.

Although there are over 55,000 social enterprises operating in Egypt, the social entrepreneurship field is still failing to create the desired social change. This paper aims to explore the challenges faced by the field with a special focus on government related challenges as well as offer a set of recommendations to the Egyptian government to enhance the field.

The research was carried out in two phases; reviewing the literature around the topic through a secondary research followed by an empirical research interviewing four social enterprises, the ministry of social solidarity and experts in the field of social entrepreneurship.

The paper arrived to several challenges and they were organized into three main themes: challenges related to policy-making and other legal aspects; challenges related to institutional and operational support; and challenges related to social, educational and cultural awareness of the field and its ecosystem. The paper also came up with a set of nine recommendations directed to the Egyptian Government.

The originality and value of this research is that it offers first hand viewpoints of the challenges facing the field of social entrepreneurship in Egypt as well as offer practical recommendations to the Egyptian Government to overcome them.

This paper aims to examine the issue that arises in the context of benchmark rate (or interest rate) changes made for reasons of monetary policy in a jurisdiction with a significant presence of Islamic banks. Changes, especially increases, in the prevailing interest rate made by central banks raise issues of asset-liability management for banks, which typically have longer maturities on the asset side than on the liabilities side, resulting in exposure to interest rate risk for conventional banks, and what is known as rate of return (RoR) risk for Islamic banks, which for reasons of compliance with Islamic religious law (Shari’ah) do not use interest in their operations. Islamic banks use various financial instruments which reflect the cost of funds by means of contracts of sale on credit or of leasing or forms of partnership, which allow them to earn returns on their funds and to pay returns to customers who deposit funds with them.

The methodology of this study consisted of a descriptive analysis of the relevant characteristics of Islamic banks and their economic and regulatory environments, illustrated by a case study approach applied to two jurisdictions, namely, Sudan and Malaysia.

In jurisdictions where Islamic banks represent a significant share of the market for financial services, if the contracts used in Islamic financing allow for periodic adjustments of the profit rate or lease rental, this could result in a significant impediment to the full implementation of monetary policy and hence to the maintenance of financial stability.

This study is (to the best of authors’ knowledge) the first thorough analysis in the literature of the issues arising from the exposure of Islamic banks to RoR risk and has clear implications for regulatory and central bank policy.
