The study investigated the potential non‐linear impacts of fluctuations in oil prices on domestic prices in Nigeria. Utilising the non‐linear autoregressive distributed lag (NARDL) model, the study revealed the presence of asymmetry in the behaviour of domestic prices. Both forms of oil price shocks were observed to have a negative influence on dom...

Given the perception that Önancial inclusion is a critical tool for the eradication of income inequality, this paper investigates its impact on income inequality in Nigeria via three Önancial variables: depth, access and stability. The study adopts the Autoregressive Distributed Lag (ARDL) methodology on selected variables from 1981 to 2021. The st...

This study empirically investigates the inflation, exchange rate and remittance inflow nexus in Nigeria. Using data from 1980 to 2022, it employs the vector error correction model (VECM) to estimate the relationship among the variables of interest and granger causality to test their direction of causality. The VECM result shows that there is a stat...

Using the Autoregressive Distributive Lag (ARDL) model and bounds testing approach on data from 1980 to 2021, the results indicate that remittance inflow have a positive...

Mobile money is a technological innovation in the financial sector that provides numerous benefits to an economy. Despite these perceived benefits, there are concerns regarding the impact of this innovation on macroeconomic variables. This study therefore employed data from 2008M1 to 2018M12 to test the responsiveness of some macroeconomic variable...

Unlike other studies that examined the stock market response to variations in monetary policy and fiscal policy in isolation, this study analyzes Nigeria’s stock market response to the joint interactions between fiscal and monetary policies. Employing the SVAR model on quarterly data from 1990Q1 to 2016Q4, the accumulated impulse response shows tha...

Investigated the impact of crude oil price shocks on the returns and volatility of the Nigerian stock market. Since not all industries are expected to be equally affected by oil price changes, the study was conducted at disaggregate firm level for two sectors namely Banking and Oil &Gas. A bivariate VAR-GARCH model was employed for the daily observ...

This study investigates the validity of the Environmental Kuznets Curve (EKC) hypothesis for carbon emissions (CO 2) in Nigeria for the period 1990 to 2016. The study revisited the Shen (2006) argument of increased explanatory variables in the income-pollution relation. Two additional variables were included: energy demand and the human development...

This study investigated the nexus between income inequality and health status in Nigeria. Life expectancy, public health expenditure and infant mortality rate were used as proxy for health. The study presumed that the link between income inequality and health is better investigated through the use of inter-temporal measures such as growth rate and...

The persistent debate among policy makers and academics around combating the high rates of poverty and income inequality can be further illuminated by understanding how tourism contributes to inclusive growth, especially in developing economies. Tourism sector can be regarded as one of the key contributors to inclusive growth and where it has the c...

This study examined the existence of the ratchet effect in the import price-inflation rate nexus for advanced (high-income) and emerging (middle-income) countries. The study used monthly data from 1980M01 to 2019M07 and compared the potential of the dummy variable-based asymmetric model with that of the Nonlinear Autoregressive Distributed Lag (NAR...

This study investigates the effects of volatility in exchange rate on manufacturing sector's performance in Nigeria and the sector's response to shocks from this volatility. It adopts the Toda-Yamamoto variant of vector autoregressive (VAR) model on data from 1986M1 to 2019M12. Exchange rate volatility (ERV) was generated using the ARCH/GARCH model...

The study investigated the linkage between government policies and stock market performance in Nigeria from 1985-2018. It examined the linear and non-linear effects of policy interactions with stock market performance using the Bounds cointegration test and the Fully Modified OLS (FMOLS) model. The Bounds cointegration test result revealed a long-r...

This study examines the relative e§ectiveness of bank-based and market-based Önancial development on the economic growth of Nigeria with data from 1989 to 2018 us- ing the Auto-Regressive Distributive Lag (ARDL) estimation technique. The study found that bank-based Önancial development exerts positive and signiÖcant ináuence on Nigeriaís economic p...

Large external debt stock has been identified as one of the most important factors which have restricted the development of many poor countries. The consensus in the literature remains that external debt promotes growth to the extent that a country does not exceed its debt carrying capacity. Otherwise, additional debt accumulation would serve as a...

S: To investigate the nexus between energy consumption, trade openness and economic development for seven oil-producing countries in Africa, this study employs the panel Autoregressive Distributive Lag (ARDL) techniques on data from 1971 to 2017. The Levin-Lin-Chiu, Pesaran-Shin and Breitung tests were used to ascertain the stationarity of the vari...

Foreign direct investment (FDI) is an investment geared towards controlling ownership in a business enterprise in domestic country by an entity based in a foreign country. It is one of the major sources of capital inflows to developing countries, from the resource surplus countries and among developing countries themselves, and has been widely cons...

The crux of the study was to ascertain whether (and to what extent) the different deficit financing options impacted inclusive growth in India and Nigeria. The paper conducted an empirical analysis using data covering the period from 1989 to 2018 using the ARDL model. Some interesting results were obtained. First, foreign aid positively impacted in...

This study examines the nexus between stock market returns and three interrelated macroeconomic variables. Given the magnitude of interest rate spread, unstable inflation rate and the volatile nature of exchange rate in Nigeria, this study analyses how sensitive the stock market return is in the light of the options and constraints facing investors...

Successful policy implementation requires an accurate assessment of the magnitude at which the effect of monetary policy change propagates to other sectors of the economy. For this reason, a thorough understanding of the mechanism through which monetary policy affects targeted economic variables is necessary. This study used innovation accounting i...

This paper reexamined the relationship between oil price shocks and the performance of the Nigerian stock market. Unlike extant attempts, daily data on oil price shocks and stock returns for the period spanning February 2004 to December 2013 was deployed. The results for the benchmark (linear) oil price model showed the impact of oil prices on stoc...

This study employed a SVAR model to establish that monetary authority in Nigeria used a hybrid of operating procedures to pursue price stability and growth objectives.

This study develops and uses for forecast a small-scale macro-econometric model of the Nigerian economy. The effects of three policy scenarios built around the assumptions of the changes that the Central Bank of Nigeria is likely to make to the Monetary Policy Rate are proposed and analyzed. Trade-off among the scenarios is identified in terms of t...
