Examining the nexus between tax revenue and economic growth: Empirical evidence from Nigeria

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.

ETHNOCENTRISM AND CONSUMER-BASED BRAND EQUITY OF CONSTRUCTION FIRMS IN SOUTH-SOUTH NIGERIA: THE MODERATING ROLE OF BRAND TRUST

2026-10-15T08:36:39+00:00

This research investigated how consumers' preference for domestic products impacts the value they place on local construction companies in the South-South region of Nigeria. This study utilized the cross sectional survey design. The population of the study is one thousand two hundred and thirty one (1,231) employees of working under the various states ministry of works. The random sampling technique was adopted as respondents were directors and their secretaries because of their relevant experiences and sufficient knowledge on the subject matter. Each department had two (2) representatives, purposively drawn from each of the functioning seven departments and three units; human resources management, planning research and statistics, finance and accounts, civil engineering, engineering services, quantity surveying and building services, design and structure, audit unit, legal unit and press unit. Thus the sample size is 120. However, only 116 of responses were valid for analyses. The results showed that there is a substantial association between the ethnocentric dimensions and the consumer-based brand equity measures, derived from the bivariate and multivariate analysis. Accordingly, the study suggests that, based on the results, Construction companies should focus on investing in local resources and employing native workers while supporting community advancement. This approach can foster long-term loyalty and brand advocacy among ethnocentric customers. Considering that consumer patriotism affects brand preference and loyalty, firms should implement branding strategies that underscore their role in national progress, local employment, and infrastructure development.

CURRENT ASSET INVESTMENT AND PERFORMANCE MEASURES OF LISTED OIL AND GAS FIRMS IN NIGERIA

2026-10-29T07:49:42+00:00

This study examined the relationship between current asset investment and the performance of listed oil and gas firms in Nigeria. Specifically, the study examined the influence of cash and cash equivalents on return on assets and evaluated the relationship between accounts receivable and return on assets of selected listed oil and gas firms in Nigeria. The study adopted an ex-post facto research design and relied on secondary panel data obtained from the annual reports and financial statements of six purposively selected listed oil and gas firms covering an eleven-year period, resulting in 66 firm-year observations. Data were analysed using panel stationarity tests, panel cointegration tests, Panel Autoregressive Distributed Lag (ARDL) estimation and the ARDL Error Correction Model (ECM). The findings indicated that cash and cash equivalents had a positive and statistically significant effect on return on assets in both the short and long run. In contrast, accounts receivable had a negative and statistically significant effect on return on assets in both the short and long run. The significant and negative error-correction coefficient confirmed the existence of a long-run equilibrium relationship and indicated that deviations from equilibrium were corrected over time. The study concluded that the performance implications of current asset investment differed according to the component of current assets considered. It recommended that listed oil and gas firms maintain adequate liquidity while avoiding excessive idle cash and strengthen receivables management through effective credit assessment, monitoring and timely collection of outstanding debts.
