This study empirically and comparatively analyses the insurance companies’ investment portfolios and their contributions to economic growth in Nigeria. The study covers the period from 1980 to 2025. It employs Unit root, Co-integration and Error Correction Model techniques in analyzing the secondary data sourced from Central Bank of Nigeria Statistical Bulletin. The results indicate that the time series data are stationary and prevalence of a significant long run relationship between various proxies of insurance companies. Investment portfolio and economic growth proxied by gross domestic product. Specifically, the results provide evidence that Insurance sector’s investment in Stocks and Bonds (STB), Real Estate and Mortgage (REM) as well as Cash and Bank Deposit (CBD) are all significant in explaining variations in gross domestic product (GDP), the dependent variable. On the other hand, however, insurance sector’s investment in Government Securities (GSE), shows insignificant relationship with the dependent variable, gross domestic product. This implies that investment portfolios of insurance companies have varied contribution to economic growth in Nigeria within the period under study. Consequently, the study recommends among others that insurance companies in Nigeria should increase their investments on government securities, real estate and mortgage, policy and other loans, as well as cash at hand and deposits for more feasible contribution to the economic growth in Nigeria.

This study examined the effect of port infrastructural development on cargo delivery efficiency at Tin Can Island Port, Nigeria, using a quantitative survey design based on primary data collected with a structured fourpoint Likertscale questionnaire. Andrew Fisher’s formula produced an initial sample size of 384.16, which, after finite population correction, was adjusted to approximately 278 respondents, ensuring adequate power for statistical analysis and feasible field administration. The regression results at a 95 percent confidence level show a strong relationship between infrastructural development and cargo delivery efficiency, with correlation coefficients up to R = 0.852, coefficients of determination R2 = 0.726 and adjusted R2 = 0.722. The key infrastructure predictors; berth/equipping facilities, cargohandling equipment, storage infrastructure and power/ICT systems, exhibiting positive, statistically significant effects at p < 0.001. Berth/equipping facilities consistently emerged as the most influential predictor, followed by cargohandling equipment, power/ICT and storage infrastructure, indicating that physical and mechanical constraints are critical drivers of efficiency outcomes. The study concludes that comprehensive infrastructural upgrading is an evidencebased core strategy for improving cargo throughput, vessel turnaround time and overall delivery performance at Tin Can Island Port, but that residual variance points to the need for complementary operational and regulatory reforms. It recommends phased berth rehabilitation and equipment modernization, investments in reliable power and integrated ICT platforms, and process reengineering of clearance, labour practices and hinterland connectivity to secure sustainable, systemwide efficiency gains

This study examined the relationship between leadership humility and employee performance in deposit money banks in Nigeria. Leadership behaviors that increase staff productivity have become essential to organizational success as the banking sector continues to face growing competition, technological change, and increased client demands. The study examined the relationship between employee performance as determined by task performance and contextual performance and the three elements of leadership humility: self-awareness, appreciation of others, and teachability. A quantitative cross-sectional survey research design was adopted, and data were collected from employees and management staff of selected deposit money banks in Nigeria using a structured questionnaire. Data were analysed using the Statistical Package for the Social Sciences (SPSS) through descriptive statistics, Pearson Product Moment Correlation, and multiple regression analysis. The findings revealed that leadership humility has a significant positive relationship with employee performance. Specifically, self-awareness enhanced employee trust, accountability, and job effectiveness; appreciation of others emerged as the strongest predictor of employee performance by improving motivation, commitment, and recognition; while teachability significantly promoted collaboration, continuous learning, and knowledge sharing among employees. The study concludes that leadership humility is an important determinant of employee performance in deposit money banks, as leaders who demonstrate humility create supportive work environments that encourage higher levels of task and contextual performance. The study recommends that deposit money banks should incorporate leadership humility into leadership development programmes, strengthen employee recognition practices, encourage continuous learning among leaders, and integrate humble leadership behaviours into leadership selection and performance evaluation systems to improve employee effectiveness and organizational performance.

The study investigated globalization challenges on organizational sustainability of multinational corporation (MNC) in South-South, Nigeria. The specific objectives are to ascertain the effect of political decisions and disruptions on the operational strategies, determine the effect of economic developments on efficiency. The research design used in the study was a survey design. The researcher adopted primary source of data. The total population of the study was eighty thousand seven hundred and twenty-four (8724) respondents from the selected study areas. The sample size of the study was five hundred and sixty-one (561) derived from Godden formula. Simple random sampling technique was used in this study. Pearson correlation coefficient and regression model were used to test the hypotheses of the study. A total of five hundred and sixty-one (561) copies of questionnaire was administered to the selected Multinational firms in South-South, Nigeria, during the collection of the administered questionnaire, forty-nine (49) copies questionnaires were wrongly filled, misplaced, void and discarded with a percentage rate of 8.6%, while the questionnaire retrieved was five hundred and twelve (512) with a percentage ratio of 91.4% that aided the study. The findings of the study stated that there is a significant relationship between political decisions and disruptions on operational strategies of multinational corporation (MNCs) in South-South, Nigeria. Economic developments does significantly influence efficiency of multinational of corporation (MNCs) in South-South, Nigeria. In conclusion, if political decisions are flexible and eschew selfish interest, it will be of great benefit to tackle challenges facing the global market and multinational firms.

Sustainability initiatives in Nigeria have emerged in response to environmental challenges and the global call for sustainable development. The integration of green accounting into resource management practices is crucial for assessing the environmental impacts of corporate activities, identifying avenues for cost-effective innovations, and improving sustainability reporting. The objective of this investigation is to elucidate how green accounting and sustainability practices facilitate the enhancement of innovation concerning resource management from an accounting standpoint. This research employs an ex-post facto research design of 16 listed firms on the Nigerian exchange group for 11 years periods using the purposive sampling technique. The two formulated hypotheses were tested using the regression analysis. The result shows that green accounting (GA) exerts a positive influence on innovation in resource management (IRM) and that Green accounting effect on sustainability practices is of high statistical significance. The study concludes that green accounting practices have the potential to assist organizations in recognizing and managing environmental costs and benefits, thereby fostering innovation in resource management. It was recommended among others that firms should dedicate efforts towards continuous investment and the generation of innovative ideas in the realm of resource management practices.
