The sustainability of South African automotive component suppliers faces increasing pressure due to global supply chain disruptions and heightened buyer demands. Within this competitive environment, traditional differentiators such as price and product quality are largely prescribed by buyers, leaving suppliers with limited strategic levers. Relationship quality has therefore emerged as a crucial factor in building trust and securing long-term customer retention. The central research question is: What is the correlation between trust and relationship quality in buyer-supplier exchanges within the automotive supply chain? This article reports on a quantitative study that examined the relationship between supplier–buyer relationship quality and the development of trust. A directional linear relationship between these constructs was tested to determine the extent to which relational factors contribute to sustainable partnerships. The findings indicate a strong and significant correlation, suggesting that supplier actions during sourcing interactions can meaningfully influence levels of trust. Trust, in turn, enhances perceived customer value and contributes to customer retention in an industry where competitive advantages are narrow. The study underscores the need for South African automotive component suppliers to prioritise strategies that strengthen relationship quality with their buyers. By fostering trust through relational practices, suppliers may achieve more resilient business outcomes and sustain their market position within a challenging global supply chain environment.

Taxes are essential in protecting the infrastructure as a great portion of government spending comes from taxes. Understandably, factors like taxpayers’ religiosity, tax amnesty, and tax sanctions have a bearing on taxpayer compliance, an important aspect if the optimal tax required for financing infrastructure is to be maintained. This study seeks to determine how taxpayer religiosity, tax amnesty, and tax sanction influence tax compliance of micro, small and medium enterprises (MSMEs) in Indonesia. A quantitative research method was applying using several liner regression analyses, with three variables as independent focusing on taxpayer religiosity (X1), tax amnesty (X2), tax-sanction (X3), and one dependent variable taxpayer compliance (Y). The research was within MSMEs, and a random sampling technique was used in drawing the sample. Questionnaires were used to elicit primary data while secondary data was collected through literature reviews such as journals, books, and other published materials. The two tests were ascertained and the hypothesized constructs were tested using SEM techniques within SmartPLS. The results of this research show that, 1) Taxpayer Religiosity has a positive and significant effect on Taxpayer Compliance of MSMES in Indonesia. 2) Tax amnesty has a great impact on taxpayer compliance amongst MSMEs in Indonesia. 3) Tax sanction significantly affects taxpayer compliance amongst MSMEs in Indonesia. The research shows that taxpayer religious beliefs, tax amnesty, and tax sanction leads to high levels of tax compliance amongst the MSME sector in Indonesia. It aids in the formulation of necessary moves by the concerned authorities that would in one way or the other address the issue of compliance among the MSMEs.

 This paper utilizes the Least Squares Dummy Variables (LSDV) technique in investigating the effect of financial depth on economic growth within a sample of middle-income countries, over the period 2005–2017. The research finds that financial depth has a negative impact on real GDP growth within middle-income countries. This result is robust to the use of alternative measures of financial depth, the use of per capita GDP growth as a proxy for economic growth, the inclusion of dummy variables to control for the 2007–2010 global financial crisis, the exclusion of countries with high average growth as well as across income levels. Based on its findings, this study recommends the need for robust regulations to ensure that the credit facilities of domestic financial institutions are channeled towards productive investments rather than debt servicing.
