The purpose of this paper is to present the results of a meta-analysis of the relationship between determinant factors and tax evasion based on deterrence approach. Using the meta-analysis method, each statistical result of empirical studies is converted into r-pearson as standardized effect size, and then synthesized into a mean effect size in order to increase power and to resolve uncertainty. Theoretically, increasing audit, tax rate and tax penalty will decrease tax evasion. However, the results show that only tax rate has a significant impact on tax evasion. Synthesizing totally 478 outcomes from articles published between 1978 and 2018, there is a robust conclusion that decreasing tax rate is an effective tool in combating tax evasion. On the other hand, audit and penalty are not significant in influencing tax evasion. In addition, the results of heterogeneity analysis suggest that national culture and income level of the country are useful in explaining the impact of audit, tax rate and tax penalty on tax evasion. These findings should be of interest to policymakers. First, instead of sacrificing more resources in conducting audit or imposing more penalty, tax authorities should consider setting the tax rate as low as possible to diminish tax evasion. Second, considering that culture and income level influence the impact of audit and penalty on tax evasion, policymakers should consider national cultural values and income level condition when designing audit techniques and setting penalty structures.

The emergence of sustainable business practices has garnered interest among stakeholders. However, the question of whether sustainability performance provides companies with a competitive advantage is still being debated in the literature. This paper aims to examine the influence of sustainability performance – namely economic sustainability performance and environmental, social, governance (ESG) – on competitive advantage, with the effectiveness of enterprise risk management (ERM) as the moderating variable. This paper used 202 firm-year observations during 2015–2022 from non-financial sector companies listed on the Indonesia Stock Exchange. To test the hypotheses, panel data regression with a one-year time-lag analysis is conducted. The findings show that economic sustainability performance has no relationship with competitive advantage, while ESG has a positive effect. Furthermore, ERM effectiveness strengthens the effect of economic sustainability and ESG on competitive advantage. Further investigation used a two-year time-lag analysis for a long-term perspective. The analysis shows that economic sustainability performance and ESG have a positive impact on competitive advantage. In contrast, ERM effectiveness has no effect on the relationship between economic sustainability performance and competitive advantage. Moreover, additional analysis incorporates the effect of COVID-19 into the main model and shows that the pandemic did not affect competitive advantage; this is consistent with the main results. The findings encourage companies to improve their risk management and sustainability initiatives. The government may also take it into account when developing rules that promote the implementation of sustainable development.
