This study aims to investigate factors that affect IPO oversubscription on Islamic stocks. Using data of 202 IPOs indexed from Indonesia Sharia Stock Index, this study uses ordinary least squaresand quantile regression to test the formulated hypothesis from 2011 to 2020. This study finds that issue price and issue size negatively affect IPO oversubscription. Meanwhile, firm size and raw return positively affect IPO oversubscription. The findings of this study offer implications forcompanies especially related to go public subscription. This study can be reference for investors as well when engage in IPO related activities for Islamic stocks.

This study employs bibliometric analysis to evaluate 443 scholarly works on the topics of Indonesian Islamic banking published on 194 academic platforms, and authored by 1049 scholars. The machine learning tools i.e., R Studio and VOSviewer were employed to analyse the Scopus’ bibliographical data automatically harvested from the database. We developed four research questions based on the theories that are fundamental to bibliometric study, i.e., performance analysis, citation and co-citation analyses, bibliographic coupling and social network analysis, to identify the most impactful manuscripts, scholarly journals, authors, and institutions of affiliation. We further established the discussion of the current issues in Indonesian Islamic banking topics from the keyword analysis and the bibliographic coupling. These findings derive some recommendations for future research. This study provides a supply of scholarly novelty in the assessment of Indonesian Islamic banking publications which are both practically and theoretically importance to regulators, academia and industry professionals.

The interaction of social norms and incentives is a subject of growing interest in economic literature. Basov and Bhatti (2013) pointed out that invoking a social norm is both a blessing, since it allows mitigating moral hazard problem, and a curse, since it restricts the class of admissible contractual arrangements. In this paper, we reiterate this point using particular example of the effects of restrictions imposed on contracts by Shariah law on the optimal risk-incentive trade-off. We show that extra rigidity imposed by Shariah law leads to a greater reluctance to invest into daring new ideas, which are profitable in expectation, but may also result in significant losses. A shared set of social norms between the lender and the entrepreneur allows mitigating adverse consequences of the excess rigidity through creation of good will and may even lead to an improved performance. The adverse consequences may vary according to the stages of business cycle. As a result, recessions can have negative long-term effects and longer booms may be followed by longer recessions. We also hypothesize that turning a social norm into a law will deprive it of the ability to generate good will, while leaving the negative aspects intact. We find a tentative support of this hypothesis by comparing relative performance of Islamic banks in three regions: South East Asia (primarily, Malaysia), Middle East, and the UK.

This study examines whether Islamic gold-backed cryptocurrencies (Onegram and X8X) provide any diversification benefits to the Islamic investors of Indonesia. We study the co-movements between return and volatility of cryptocurrencies and Indonesian Islamic equity indices during the pre-COVID-19 and COVID-19 periods. We employ Multivariate Generalized Autoregressive Conditional Heteroscedastic-Dynamic Conditional Correlation (M-GARCH-DCC) and Continuous Wavelet Transforms (CWT) for this study. We find that the COVID-19 crisis enhanced the spillover effect among the Islamic gold-backed cryptocurrencies and Islamic equities. We also provide evidence that Indonesian investors may invest in cryptocurrencies to minimize the equity sector risks during the pandemic. Our results bear significant implications for portfolio diversification strategies for Indonesian investors.

The purpose of this study is to calculate Zakat proceeds in Bangladesh by using both classical and contemporary or alternative Zakat calculation methods. The results reveal that the percentage of Zakat amount to GDP is significantly higher than the average, i.e., 2.5-3%; under the classical and alternative approaches, the Zakat proceeds are estimated as 3.79 and 2.33 percent of GDP, respectively.

This study examined the relationship between religiosity, saving intention, and saving behavior among Muslim university students in Palembang, Indonesia. A quantitative research approach was employed for this study. A total of 103 respondents were students aged between 18 and 22 years. Analyses were carried out using the partial least square path modeling (PLS-PM) technique in R-Studio (version 4.0.3) through cSEM: Composite-Based Structural Equation Modelling package. Data supported all three hypotheses, with all path coefficients being positive and statistically significant. Religiosity was found to have a significant positive relationship with saving intention and behavior. In addition, saving intention and saving behavior had a significant positive relationship. Meanwhile, according to Cohen’s convention, the effect size of the association between religiosity and saving intention and behavior was small.

This study aims to investigate the effect of Islamic Financial Literacy on the intentions of prospective Muslim investors to invest through the Islamic securities crowdfunding FinTech (I-SCF FinTech) platform. With employed Partial Least Square – Structural Equation Modeling, this study used 100 valid samples from the total 125 questionnaires filled in. The sample technique was Simple random sampling with convenience technique. Data were obtained through filling out online questionnaires using a google form containing questions adopted from relevant research. We also employed the Technology Acceptance Model (TAM) combined with the Theory of Planned Behavior (TPB) which also integrated with Islamic Financial Literacy (IFL) focused on investment. The main finding in this study is that IFL switch is the identity as well as the risks inherent in Islamic financial products is found to have a significant effect on behavioral intention. The results of this study are expected to add to the scientific treasures on the side of investors' intentions to adopt I-SCF FinTech which is still very rarely done. Practically, the research has implications for the need to strengthen product and contract literacy followed by supervision and implementation of contracts that are in line with sharia principles through synergy between the Financial Service Authority (OJK) and the crowdfunding FinTech associations as well as relevant stakeholders.

Economic growth is the increase in the production of goods and services per head of population over a stated period of time (Oxford Dictionary). This study explores the short run and long run effect of financial development, governance, institutional quality, democracy, Islamic finance on economic growth in the time period of 2002-2020 for Pakistan. An ARDL method is applied for checking the cointegration among variables. The results indicate the existence of short run and long run cointegration among economic growth, financial development, governance, institutional quality, democracy, and Islamic finance. We recommend policy makers to provide comfortable environment and institutional support to boost sustainable inclusive economic growth after considering the above mentioned aspects especially in post covid-19 world.

This study analyzes the risk-taking behavior of Indonesian Islamic Banks by examining whether the relation between financing Growth rate and non-performing financing (NPF). We employ threshold regression models and bank-level data of 24 Islamic banks (full-fledged Islamic banks and Islamic banking windows) covering the period from 2009 to 2019. We find evidence for the excessive risk-taking of Islamic Banks. More specifically, while the relation between NPF and FGR is negative when the one-lagged NPF is below the threshold (estimated to be 5.42%), it turns positive once it is above the threshold. This means that banks with NPF above the 5.42 percent threshold tend to take risky loans.
