2026-09-14T11:46:48+00:00

In this paper we study the impact of tax revenue on economic growth in Nigeria for the period of 1990 to 2022. The aim of this study was to find out whether petroleum profit tax, company income tax, custom and excise duty and value-added tax have consequences for economic growth, measured using real gross domestic product (GDP). This paper investigated the relationship between tax revenue and economic growth using secondary data which was sourced from the Central Bank of Nigeria (CBN) Statistical Bulletin and the Federal Inland Revenue Service (FIRS). The study used the autoregressive distributed lag (ARDL) estimator in estimated the multiple regression model, in addition to unit root and cointegration tests approaches used to determine the integration process of the series and possible long run relationship between the employed variables. The bounds test result revealed there is long run relationship between tax revenue and economic growth. The results revealed that petroleum profit tax and value-added tax had positive and significant impact on economic growth. Company income tax had positive and insignificant effect on economic growth, while the study showed that custom and excise duty had negative and insignificant effect on economic growth. Based on this result, the study recommends that revenue from petroleum profit tax and VAT should be used to provide growth enhancing infrastructures and the Federal Government should leverage on technology for revenue collection by automating revenue collection processes in order to reduce face-to-face contacts that breeds corruption and reduce the amount of revenue going into the government coffers.

The Concept of Native Wisdom: An Indigenous Management Capability

2026-09-14T12:37:31+00:00

This paper explores the concept of native wisdom as an indigenous management capability within the context of African organizational settings. Adopting a theoretical and exploratory approach, the study re-conceptualizes native wisdom as a strategic, culturally embedded resource that enhances managerial effectiveness and organizational relationships. The paper identifies five core dimensions of native wisdom such as cultural insight, communal orientation, ethical prudence, experiential judgment, and relational harmony which collectively shape decision-making, leadership behavior, and workplace interactions. Drawing on the knowledge-based view and socio-cultural perspectives, the study argues that native wisdom represents a unique form of tacit knowledge that is difficult to replicate and therefore contributes to sustained organizational advantage. It further demonstrates that leaders who integrate native wisdom into their practices are better positioned to foster trust, manage conflict, and promote collaboration within diverse organizational environments. The paper also contributes to the development of contextualized African management theory by challenging the dominance of Western-centric models and emphasizing the relevance of indigenous knowledge systems. Practical implications highlight the need for organizations to incorporate cultural competence, experiential learning, and ethical sensitivity into leadership development and management practices. The study positions native wisdom as a critical driver of organizational effectiveness and a foundation for more inclusive and contextually relevant management frameworks.

The study investigated trade finance gap and effects on the export performance of Nigerian small and medium-sized enterprises (SMEs). The objectives of the study were to examine the effects of commercial bank credit to SMEs and aggregate export credit on non-oil exports, and to determine the roles of the prime lending rate and exchange rate in influencing export performance. The study drew from the Stiglitz-Weiss Credit Rationing Theory, which explains the way informational asymmetries separating lenders from borrowers prompt financial institutions to constrain credit availability even when firms are willing to borrow. Annual data covering 1991–2025 were obtained from the Central Bank of Nigeria, the National Bureau of Statistics, and the World Bank’s World Development Indicators repository, structured around an ex-post facto quantitative research design. The ARDL bounds testing technique and Error Correction Model were used to evaluate both short-term dynamics and long-term co-integration among the specified parameters. The results showed that commercial bank SME financing and total export credit exert a statistically significant positive influence on non-oil export growth (p < 0.01), while the prime lending rate has a significantly negative effect, with a coefficient of -0.045. The exchange rate also enhances export price competitiveness. The ECM coefficient of -0.425 showed that about 42.5% of any short-run disequilibrium is corrected each year. It recommended that monetary authorities, specifically the Central Bank of Nigeria, should introduce a 5% credit allocation requirement for commercial banks to support SMEs engaged in non-oil export activities.
