Financial development and shadow economy in Africa: evidence from panel quantile regression
(Emeraid insight, 2023-06) Onwuka, I. O; Emmanuel, A.
"The study investigated the impact of financial development on shadow economy in Africa, using data for 41 African countries. The informal outputs, computed by Elgin et al. (2021), and the three financial development indicators were sourced from the World Bank and International Monetary Fund (IMF) respectively. The dynamic panel quantile regression technique was employed as it captures better the nature of the African economy and the heterogeneous nature of the shadow economies. The study shows that average FIA and FID in Africa is 0.074 and 0.160 respectively; suggesting that accessing credit from financial institution, as well as the coverage of credit and other financial services in Africa is low and could be accompanied with high degree of bottlenecks. The FIE on average is 0.520; suggesting that credits from financial institution in Africa are used for their intended purposes. However, financial
development must be pursued alongside other macroeconomic goals, particularly urbanization.
Portfolio Management and Performance of Deposit Money Banks in Nigeria (1990–2020)
(Elsevier Ltd, 2025) Fajinmi, C.; Onwuka, I. O.; Ayeni, E.
There have been a renewed focus on portfolio management of deposit money banks since the global financial crisis of 2007–09. This renewed focus is based on the understanding that an efficient portfolio management reduces risks and loss associated with uncertainty of investment returns which may impact on the performance of banks. In this study, we investigated the connection between portfolio management and performance of deposit money banks in Nigeria. The study essentially sought to ascertain whether portfolio management has predictive value for the out-of-sample predictability of profitability of deposit money banks in Nigeria. The Markowitz portfolio theory underpin the study while time series data on deposit money banks’ liquidity, financial assets, foreign portfolio asset, deposit mix, and private sector concentration were utilized for the analysis. The time series spanned from 1990 to 2020 based on data availability. To increase the robustness of the result, the entire 24 DMBs were included in the study. The unit root test and bound cointegration test were employed to check times series behaviour of the variables. The Autoregressive Distributed Lag (ARDL) was used to estimate both the short-run and long-run dynamics and rapid correction to long-run equilibrium. Our findings reveal that portfolio management and its variants had significant effect on the profit after tax (PAT), return on investment (ROI), asset quality (ASQ), and capital adequacy (CA) of deposit money banks in Nigeria.
Impact of covid-19 pandemic on microfinance banks in Nigeria
(Savings and Development, 2022) Onwuka, I. O.; Nwadibu, A.; Okwara, U. K.
The outbreak of the novel coronavirus (COVID-19) has created existential challenges to the Nigerian economy especially the microcredit delivery system and microfinance institutions that serve the poor and vulnerable groups in the country. The study investigated the impact of Covid-19 pandemic and the government mandated lockdown on the activities of microfinance banks (MFBs) in Nigeria using the exploratory and content analytical technique. The study found that all the key performance indicators (KFIs) of MFBs have been negatively affected by the Covid-19 pandemic. In particular, the study found that the asset quality of MFBs has deteriorated with high level of portfolio at risk (PAR). The pandemic has also affected the capital adequacy of MFBs especially the state and unit MFBs due to increased and large provisioning for loan losses. In consequence, the shareholders’ funds for most of the state and unit MFBs have been seriously eroded and impaired by losses. Among others, the study recommended for an urgent regulatory forbearance and injection of liquidity in the sector by the Central Bank of Nigeria through a bail-out and to enlarge the CBN discount window to accommodate eligible MFBs to discount facilities that are hitherto only available to deposit money banks (DMBs).
Budget deficit, inflation and economic growth in Nigeria: an empirical analysis
("Academic Research Publishing Group", 2022) Onwuka, I. O.
The taxonomy established by Wagner and Keynes on the effect of government expenditure on economic growth has continued to generate a series of empirical studies but so far no consensus has been achieved on the exact nexus between deficit financing and economic growth and when interacting with inflation variable. The study contributed to this debate by using the disaggregated Vector Autoregression (VAR) approach to investigate the impact of deficit financing on economic growth with inflation as an interaction variable. The study found, amongst others, that overall deficit financing had a positive and significant impact on economic growth when financed through external sources but had a deleterious effect when financed through domestic sources. This could be attributed to the crowding-out effect of the private sector when deficit financing is funded through the domestic loan market. The study also found that overall deficit financing is inflationary which also resulted in to decrease in real interest rates.
Does microcredit reach the poor and most vulnerable in era of pandemic? – evidence from Nigeria
(FrancoAngeli Edizioni (Italy), 2021) Nwadiubu, A.; Onwuka, I. O.
The study examined the impact of Covid-19 pandemic on households’ income and consumption – two economic measures used in measuring poverty. The study also assessed whether households especially those in rural areas are able to access microcredit because microcredit is a global recognised poverty alleviation strategy. It is widely recognized that access to micro-credit in developing countries empowers the poor (especially women) while supporting income-generating activities, encouraging the entrepreneurial spirit, and reducing vulnerability to shocks. The mixed method approach was adopted by the study. First, the study reviews the state of microcredit delivery in rural communities in Nigeria, identifies policy gaps in microcredit delivery and highlights the linkages between microcredit and poverty alleviation. Secondly, the study using a survey of selected rural communities, assessed whether households are able to access microcredit and other government palliatives put in place to mitigate the impact of the pandemic. The study found that majority of households could not access microcredit from formal microfinance institutions instead majority of the households’ resorted to informal institutions with attendant high cost of interest while government palliatives were non-existent in the communities surveyed. The study recommended that acknowledging the role of the informal actors in microcredit delivery is the critical first step towards framing a sustainable microcredit delivery policy in which both the formal and informal institutions are involved in microcredit delivery and governance.
