This paper aims to investigate the relationship between capital risk and efficiency of Islamic and conventional banks operating in Bangladesh. In this pursuit, the research attempts to answer these questions: do inefficient banks assume more risk? Is there any major difference between Islamic and conventional banks in terms of efficiency and risk taking behavior?

The study collects various bank-level data from the audited financial statements of Islamic and conventional banks for the period of 2001 to 2011. Collected data are analyzed using Stochastic Frontier Analysis for efficiency estimation and Seemingly Unrelated Regression (SUR) approach for assessing the relationship between capital, risk, and efficiency.

Analysis of data shows that conventional banks are more efficient in managing cost than Islamic banks. Moreover, the SUR results show that the relation between capital and efficiency are bidirectional and negative, whereas the relation between capital and risk is also bidirectional but positive for Islamic banks. On the other hand, risk and efficiency are positively related, and the result is bidirectional for conventional banks.

The research concentrates on private-commercial banks as proxy for conventional banks. State-owned banks including specialized banks and foreign commercial banks are excluded from the sample due to various anomalies in reporting of financial data.

There is a lot of room for Islamic banks to increase productive efficiency because cost efficiency of Islamic banks is less than that of the conventional banks. This can be attributed to the relative small size of Islamic banks in Bangladesh. Because there exists a positive relationship between size and efficiency for Islamic banks, they can concentrate on increasing their size to capitalize on economies of scale. Moreover, the analysis shows that inefficient conventional banks assume higher risk which conforms to moral hazard hypothesis. Therefore, regulatory authorities should discourage banks from exercising such practice for the greater stability of the overall banking system in Bangladesh.

A good number of studies is available in the existing literature that compares the performance of Islamic and conventional banks in the case of Bangladesh. However, very few studies are found that examine the relationship between capital, risk and efficiency. Therefore, the research is new for the selected area. As a result, the research is expected to contribute to the existing literature by providing new information.

The ownership structure in Japanese firms has experienced a significant change recently, fueled primarily by regulatory changes. This has important repercussions on corporate performance and risk. This paper examines the impact of insider ownership on the default risk of Japanese firms.

We collected data from the Nikkei Corporate Governance Evaluation System (CGES) database for the period 2004–2019. Our final dataset yields 36,116 firm-year observations. We apply a firm fixed effect model for baseline regression. Endogeneity was checked by applying propensity score matching (PSM) and two-stage least squares (2SLS) techniques. Furthermore, the robustness of baseline regression results was checked using alternative estimation techniques.

Results show a significant positive influence of insider ownership on default risk. Furthermore, ROA volatility and stock price volatility appear to be the major channels through which insider ownership affects a firm’s default risk. We further document that external monitoring mechanisms, including traditional main bank ties, institutional ownership and analyst coverage, are the key risk-mitigating factors.

Our research deals with Japanese firms only. Future research may attempt to analyze the cases of emerging economies. Furthermore, future research might examine the ownership-default risk relationship for financial institutions to see if this relationship differs between financial and nonfinancial firms.

Insider ownership enhances the probability of default. Hence, policymakers may consider instituting a ceiling for insider ownership in Japanese firms. Moreover, we highlight various risk-mediating channels that would help policymakers adopt guidelines for mitigating corporate risk.

Our study is the first to investigate the effect of insider ownership on default risk in Japanese settings. Prior studies identified various determinants that affect firms’ default risk. Our study contributes to this stream of literature by examining the impact of insider ownership on default risk and extending the limited literature related to insider ownership.

This paper aims to examine the impact of bank’s capital buffer on return on equity (ROE) in the context of Islamic and conventional banks in GCC countries.

The authors collect data from 83 commercial banks comprising of 49 conventional banks and 34 Islamic banks for the period 2010–2019. The final data set comprises of 744 bank-year observations. The authors apply generalized methods of moments estimation technique and panel least square to analyze the data.

The authors document that Tier-1 capital, total regulatory capital (TRC) and equity to asset ratio (EAR) negatively affect banks’ ROE. However, the impact disappears for conventional banks and sustains for Islamic banks if these two clusters of banks are treated separately. Furthermore, the negative impact of equity capital on earning is more pronounced for large and listed commercial banks.

Findings of this research imply that Islamic banks in GCC countries has scope to manage equity capital more efficiently. Hence, they should concentrate on using banks equity wisely to successfully compete with the conventional banks.

Since the global financial crisis of 2009, Islamic banks of GCC countries have been reporting lower ROE compared to their conventional counterparts. On the other hand, Islamic banks maintain higher level of Tier-1 capital, TRC and EAR. This evidence hypothetically suggests that Islamic banks are overly cautious in managing their capital buffer that results in lower ROE. To the best of the author’s/authors’ knowledge, no other study in the literature tests this hypothesis in the GCC context.

The primary objective of this study is to examine the nexus between transformational leadership (TL) and followers' radical creativity (FRC). In contrast, creative process engagement (CPE) and leader creativity expectation (LCE) was employed as a mediating and a moderator role, respectively.

A quantitative exploratory survey was applied as a research design, and 293 valid responses were collected from industry-university collaborative team leaders-followers. The authors performed descriptive and partial least square based structural equation modeling (PLS-SEM) analysis using the SPSS 23 and Smart-PLS 3.0 package program to test the hypothesis.

Empirical results revealed that the TL positively and significantly influences the FRC. Therefore, the mediation of CPE bridges the relationship between TL and FRC, while the moderating role of LCE was insignificant. TL with higher CPE indirectly enhances the FRC.

Unlike the prior conventional componential theory of creativity (CTC), this study extends the scope of CTC addressing CPE and LCE to investigate the nexus between TL and FRC and contributes to the current literature leaders-followers relationship.

Practically, this research contributes to the growing body of the literature demonstrating how organizations might foster radical creativity in their employees and how to inspire followers to participate in radical creativity activities that might enhance organizational performance.

This study has broadened the scope of the CTC by emphasizing the mediating function of CPE in promoting particular aspects of followers' creativity.
