Welfare Implication Of Alternative Tax Rates Adjustment Policy In Nigeria: A Dsge Analysis, Umar B. Ibrahim, Isah F. Abubakar

CBN Journal of Applied Statistics (JAS)

This study sets out to determine the desirable policy adjustment in the tax rate for Nigeria that ensures the least welfare cost. A calibrated small open-economy New Keynesian Dynamic Stochastic General Equilibrium (NKDSGE) model of the Nigerian economy is applied to achieve this objective. Within this framework, we examined the impact of an increase in value-added tax (VAT) rate from 7.5 to 15 percent on key macroeconomic variables relative to the impact of an increase in company income tax (CIT) rate from 30 to 35 percent on macroeconomic variables. Furthermore, we examined the welfare costs of the increases in the …

Value Added Tax Rate Variation, Import Demand And Sectoral Output In Nigeria, Joshua K. Nomkuha, Aondoawase Asooso, Philip T. Abachi

CBN Journal of Applied Statistics (JAS)

This study employs computable general equilibrium (CGE) model to estimate the effect of increase in value added tax (VAT), from 5 per cent to 7.5 per cent, on import demand and sectoral output in Nigeria. The study uses 2020 as the base year for the data analysis. The results show that increase in VAT affects import demand negatively, based on import penetration ratios, with mixed effect across six sectors. The implication of the result is that the VAT policy discourage consumption of foreign products, and constitute excess burden to consumers of such products in Nigeria. The results further reveal that …

Trade Liberalization, Non-Oil Export And Economic Growth In Nigeria, Jerome T. Andohol, Terhemen Tarzoor, Dennis T. Nomor

CBN Journal of Applied Statistics (JAS)

The study examines the impact of trade liberalization and non-oil exports on economic growth in Nigeria from 1986 to 2021. The study utilizes an autoregressive distributed lag model and found the combined effect of trade liberalization and non-oil exports to be positive and statistical significant. While trade liberalization alone may have negative consequences, its synergy with a robust non-oil export can drive sustainable economic growth. The study recommends that strategies to enhance non-oil exports should be encouraged to support the effectiveness of trade liberalization in promoting growth.

The Effectiveness Of Monetary Policy Transmission In Nigeria: Evidence From The Monetary Policy Rate And The Cash Reserve Ratio, Abdulrahman A. Nadani, Auwal Isah

CBN Journal of Applied Statistics (JAS)

This paper investigates the effectiveness of the Monetary Policy Rate (MPR) and Cash Reserve Ratio (CRR) as policy instruments in Nigeria. A structural VAR model is employed to simulate two distinct models measuring shocks from the MPR and the CRR using monthly data from January 2006 to December 2023. Findings show that contractionary monetary policy impulses using MPR and the CRR contract output and credit to the private sector, inflation remains largely positive in the two models, known as the “price puzzle”, but the puzzle is more persistent in the MPR equation. Moreover, shock to MPR strongly influences short-term interest …

External Debt Pass-Through To Inflation In Nigeria, Emmanuel A. Asue, James V. Ikyaator

CBN Journal of Applied Statistics (JAS)

This study examines external debt pass-through to inflation in Nigeria using annual data from 1981 to 2020 based on structural vector autoregressive (SVAR) model. The results reveal that an increase in external debt service leads to a significant depreciation of the exchange rate, which leads to a contemporaneous increase in inflation, while the direct response of inflation to external debt is statistically not significant. The impulse response confirms these results. The forecast error variance decomposition depicts that future values of official exchange rate depend on external debt, inflation and external debt service. The study recommends that the Nigerian government should …

Bullion

This study examines the influence of goods and money

market indicators on the performance of the Nigerian

stock market index from 1985 to 2021 using

Autoregressive Distributed Lag model. The findings

demonstrate that goods market indicators such as

domestic savings and government spending have a

strong positive effect on the performance of the stock

market index, but domestic investment has a negative

influence on the performance of the stock market index.

This is because majority of the investors in goods market

are financially excluded and have no access to formal

financial system. The results of the money market reveal

IU is measured using GARCH models and stochastic volatility model (SV). Transfer entropy was adopted to quantify the extent of information flow. The result showed information flow exists from inflation to the GARCH measure of IU. On the reverse flow from inflation uncertainty to inflation, there is no information flow except for Burkina Faso and Gambia which have asymmetric bidirectional flow between inflation and IU. Adopting SV measure for IU, there are no support for causality from inflation to …

Relationship Between Real Exchange Rate And Consumption In Nigeria: A Nonlinear Approach, Babangida Jamilu S., Sanusi Aliyu R., Yusuf Isah M.

CBN Journal of Applied Statistics (JAS)

This study analyses the relationship between real exchange rate and domestic consumption in Nigeria using the Smooth Transition Autoregressive (STAR) model from 1981Q1 to 2019Q4. Findings show that domestic consumption determines the regime shift in real exchange rate, suggesting a nonlinear linkage with clearly distinct regimes. The lagged exchange rate is shown to have a significant linear effect on the current exchange rate. On the other hand, current foreign consumption is positive but has no significant impact on the exchange rate in the linear part of the model. In the nonlinear part of the model, evidence of a significant negative …

Central Bank Of Nigeria And The Developmental Function: Some Thoughts On Policy Measurement Perceptions, Xavier-Itam Antigha Okon, Igonibo D. Abili

Bullion

The developmental function is one prominent contribution of the Central Bank of Nigeria to the Nigerian economy. Routine reporting of this function focuses on volume of projects funded, disbursements, and repayments. Exploring the possibility of expanding the reporting scope, this paper conceptualized and illustrated handy measures of policy anchored on macroeconomic aggregates, to track this function relative to other macroeconomic policy ends. Descriptive and inferential analyses suggested that the financial, economic and market intensity measures were quite responsive to developments in the economy and could be useful tools for policy reporting purposes. The pricing intensity indicator suggested distortions in the …
