The purpose of the study is to thoroughly outline how the hubris behavior of chief executive officers (CEO) is detrimental to Islamic banks’ (IBs) performance. Specifically, this study attempts to examine the role of the Sharia supervisory board (SSB), board vigilance, and CEO power in the relationship between CEO hubris behavior and decreased IBs’ performance. This study observes IBs’ performance during the period from 2014 to 2020 and develops eight models to test their determinants. Empirical testing of all models shows that CEO hubris has a detrimental impact on IBs’ performance. The moderating impact test shows the following results: firstly, the presence of SSB, which is represented by the reputation of its members, reduces the detrimental impact of hubris behavior by CEOs on IBs’ performance, while that impact, which is represented by member expertise, does not have a moderating effect. Second, the size and independence of the BOC both weaken the negative relationship between CEO hubris and IBs’ performance. Third, CEO power as represented by tenure and ownership has no moderating effect.

This study aims to examine the relationship between tax amnesty on company value, analyze the role of tax avoidance behavior to determine the direct and indirect relationship of tax amnesty on company value. The population of this study are manufacturing companies listed on the Indonesia Stock Exchange after the implementation of the tax amnesty in Indonesia in 2017–2020. The sample includes 54 companies in order to obtain 216 observational data points. A multiple linear regression model was used to analyze the relationship between the variables. The tests carried out include partial coefficient tests and model accuracy tests. The results of the study reveal that tax amnesty increases the company’s efforts to do tax avoidance. Second, the tax amnesty granted by the government could increase the value of a company. Third, success in tax avoidance efforts has an impact on increasing the value of a company. Fourth, tax avoidance mediates the relationship between tax amnesty and firm value. These results indicate that although tax amnesty can increase company value, it does not guarantee that taxpayers (companies) will stop tax avoidance.

This paper aims to study Islamic banking (IB) regulations related to the influence of the Sharia corporate governance (SCG) mechanism on financial reporting timeliness (FRTL) in Indonesia. The unbalanced panel data obtained empirically during a period that ranges from 2016 to 2019 includes observations from 54 Islamic commercial banks (ICb), 82 Sharia business unit (SBu) banks and 82 conventional banks (CB). Panel regression model is used in this study to adjust the unbalanced panel data obtained. The findings indicate that the variation of FRTL for IBs (represented by ICb) is determined by Sharia corporate governance (SCG) mechanisms. Further findings relate to a comparative study of variations in FRTL between ICb, SBu, and CBs. Although there are different determinants between ICb (SCG) and CBs (CG), there is no difference in FRTL variation between the two. Meanwhile, between ICb and SBu, whose regulations have the same determinant, there are differences between the two FRTL variations. The novelty of this paper is that, firstly, SCG is constructed on the basis of the IBs regulation to determine FRTL, and secondly, the variationі in FRTL between the IBs and CBs groups are compared.

In Indonesia, digital platforms in tax administration services have been implemented for more than a decade. This study aims to investigate whether digital platforms for motor vehicle tax administration services can increase local government tax revenues. Then, it is continued by testing the moderating role of motor vehicle tax revenue targets and online service information. Data were collected from the Unit Penerimaan Pendapatan Daerah (UPPD) Central Java – Indonesia. Observations focused on motor vehicle tax services carried out during the 2018–2022 period in 37 district and city UPPDs. The analysis uses GLS regression, which was developed with modeling regression analysis (MRA). The study results show that implementation of digital platforms in motor vehicle tax administration services can increase local government tax revenues. This relationship will be further strengthened if there are online information services, both circular and standby. Further investigation results revealed that relying on tax revenue targets to strengthen the relationship between digital platforms in tax administration services and local government tax revenues is not viable.
