The main objective of the study is to determine the impact of public debt on the Nigerian economy after the Structural Adjustment Programme (SAP). The Solow-Swan model of longterm economic growth formed the basis of the specified model to be estimated and secondary data for the study were sourced mainly from the Central Bank of Nigeria's statistical bulletin. The data for the study spanned the Post Structural Adjustment period till date (i.e. 1993-2019 due to unavailability of data). From the functional form of the model, the dependent variable is Real Gross Domestic Product while external debt stock, domestic debt stock, and public debt service payments were used to capture the public debt burden, along with government expenditure which make up the independent variables. The techniques of estimation employed in the study include the Augmented Dickey Fuller (ADF) test, Johansen co-integration, Vector Error Correction Mechanism and Granger causality test. From the findings of the study, it was seen that the public debt servicing in the previous period has a negative and significant impact on the real gross domestic product while the previous period's external debt has a positive but insignificant impact on economic growth. Thus, this implies that the current period's public debt can be useful in formulating policies that will positively impact economic growth. In light of these findings, one of the recommendations of the study is that public debt should be contracted solely for economic reasons so as to avoid accumulation of debt and its consequent negative effect on economic growth.

Ninety (90) firms were drawn as research samples among one hundred and nine (109) listed non-financial firms in Nigeria. The study was done quantitatively and conducted from secondary data obtained from the annual reports of various firms. Descriptive statistics and correlation analysis were used to determine the nature of the relationship between the independent and dependent variables. Given the hypothesis formulated for this research, the method of model estimation employed was a panel regression analysis with the aid of Stata 14 software. The findings revealed that some manipulation techniques such as incorrect asset valuation and timing of assets transaction impact positively on return on assets, thereby justifying the act, albeit unethical. Other techniques such as revenue falsification and understatement of liabilities were seen to negatively impact the return on assets. The study recommends among others, that investors should employ the services of competent financial analysts to scrutinize financial statements of firms they want to invest in.

Consequently, this study used an empirical examination to ascertain if there exists a relationship between exchange rate volatility and maternal mortality rate.Findings: The results indicated that exchange rate and maternal mortality rate both have negative impacts on each other which is statistically significant. Also, the female education enrolment reduces maternal mortality rate while the recurrent health expenditure causes it to rise, albeit not statistically significant.Contributions to theory, policy and practice: The study, therefore, recommends that the foreign exchange control policies must prioritize both foreign sector and domestic balance of the economy. The government should also focus o...

The Nigerian economy is controlled by over 70% of oil revenue and any adverse move in oil prices ... more The Nigerian economy is controlled by over 70% of oil revenue and any adverse move in oil prices affects both the government, public and private sector alike because of overt and covert dependence on oil. The Nigeria maritime industrial sector accounts for over 92% of the Nigeria export trade which is 0.31% of World export trade while the country contributes a paltry 0.49% of world GDP. These indices are provoking for an economy whose maritime sector spans over 70 years and it is incumbent on the government to urgently rethink the direction of its policies in the maritime subsector. In this studies, the authors examined the Maritime Industry Development in Nigeria with emphasis on the emerging issues. The potentials in the maritime sector were examined along with the problems confronting its growth and development. The researchers made several recommendations including-provision of conducive environment and friendly policies by the federal government and regulators such as adequate funding and access to the cabotage vessel financing funds by indigenous vessel owners, and unbundling of the maritime subsector from the ministry of Transport for speedy and effective development of the sector.
