Big Data And Inflation Forecasting In Nigeria: A Text Mining Application., M. A. Adebiyi, A. O. Adenuga, T. S. Olusegun, O. O. Mbutor

Economic and Financial Review

The success of monetary policy is substantially predicated on the availability of reliable forecast of inflation. However, the shocks arising from COVID-19 and the Russia-Ukraine war have brought about significant economic uncertainties; thus, necessitating the fine-tuning of existing forecasting models of the Central Bank of Nigeria. This study explores the usefulness of public sentiments obtained using machine learning methods to improve the predictive power of the existing short-term inflation forecasting model (STIF) in Nigeria. Findings indicate that, for all components of inflation, models that include the computed sentiment index perform better in both in-sample and out-sample forecasts than those excluding …


Pass-Through Effects Of Standing Facilities On Bank Interest Rates In Nigeria, Victor Ezeora Eleam, Chinyelu Gloria Ekwom, Chibueze Charles Ariolu, Chukwubuzo Jackson Umebali, Adewale Timothy Balogun Sep 2021

Pass-Through Effects Of Standing Facilities On Bank Interest Rates In Nigeria, Victor Ezeora Eleam, Chinyelu Gloria Ekwom, Chibueze Charles Ariolu, Chukwubuzo Jackson Umebali, Adewale Timothy Balogun

Economic and Financial Review

The paper investigates the pattern of pass-through effects of standing facilities rates on commercial bank retail interest rates in Nigeria. Monthly data spanning 2007:06 to 2019:12 and the Gregory-Hansen cointegration method that accounts for structural breaks are used in the empirical analysis. The adjustment parameters for the standing deposit and lending facilities are found to be significant, but with a low speed of adjustment. This provides some evidence on the nature of the interest rate channel of monetary policy transmission in the country. Furthermore, the study could not confirm asymmetry in the adjustment of retail rates to their long-run equilibria. …

Budget Deficit And Economic Growth In Nigeria, A. D. Umaru, H. M. Aliero, M. Abubakar Jun 2021

Budget Deficit And Economic Growth In Nigeria, A. D. Umaru, H. M. Aliero, M. Abubakar

Economic and Financial Review

This paper examines the relationship between budget deficit and economic growth in Nigeria, from a linear and non-linear perspective, using annual time series data from 1981 to 2019. The linear model, which involves the use of an autoregressive distributed lag (ARDL) approach, was compared with a non-linear analysis, using a threshold autoregressive (TAR) model. The ARDL analysis reveals that the growth of national output is positively driven by the persistent budget deficit in Nigeria. This was substantiated by the TAR model which indicates that though budget deficit drives economic growth in Nigeria, the positive relationship holds only if the deficit …

Analysis Of The Causal Link Between Economic Growth And Development In Nigeria (1960-2019), Muhammad Umar

Bullion

Taking cognizant of Nigeria's recent policies toward translating growth to meaningful development, this study aimed at analysing causality amid economic growth and development using annual series from 1960-2019.The study engaged vector autoregressive method by embracing Toda and Yamamoto 1995 model. The results reveals a bidirectional causality between economic growth and dependency ratio; population growth rate and economic growth and also it reveals the evidence of uni-directional causality from dependency ratio to life expectancy and from population growth to life expectancy. But economic growth and life expectancy as well as dependency ratio and life expectancy does not present evidence of causality.


Capital Adequacy Requirement And Bank Behaviour In Nigeria, Baba Nmadu Yaaba, Lailah G. Sanusi Jun 2020

Capital Adequacy Requirement And Bank Behaviour In Nigeria, Baba Nmadu Yaaba, Lailah G. Sanusi

Bullion

The divergent views on the usefulness of capital adequacy ratio (CAR) in controlling the risk appetite of banks necessitates further research on its efficiency and effectiveness. Whereas proponents of CAR believe that it enhances the soundness and stability of the banking system, opponents contend that it can impedes on the intermediating capabilities of banks and possibly ignites credit crunch that could induce fall in the level of output. This study empirical verifies the infuence of CAR on the behavior of banks in Nigeria. The study adopts a system of simultaneous equation, in the tradition of Maraghni (2017) using Generalized Method …


Macroeconomic Instability Index And Threshold For The Nigerian Economy, B. A. G. Amoo, J. K. Achua, N. P. Audu, B. Hamma Jun 2017

Macroeconomic Instability Index And Threshold For The Nigerian Economy, B. A. G. Amoo, J. K. Achua, N. P. Audu, B. Hamma

Economic and Financial Review

The paper employed statistical algorithms, factor analysis and threshold autoregressive models to address the gaps in management of macroeconomic instability in Nigeria. Using data spanning 2010q1 to 2017q2, the findings showed that the values of macroeconomic instability index (MII) fluctuated between 0.316 and 0.609, with a threshold of 0.461. This showed an inverse relationship between macroeconomic instability and economic growth. This framework could serve as a mechanism to gauge early warning signal of instability in Nigeria.


Unofficial Dollarisation And Monetary Policy In Nigeria, Y. Adamu Jun 2017

Unofficial Dollarisation And Monetary Policy In Nigeria, Y. Adamu

Economic and Financial Review

This paper examined the impact of dollarisation on monetary policy in Nigeria, using monthly data spanning 2002 to 2016. The paper adopted the conventional IMF proxy for dollarisation and traced its reactions to changing monetary policy stance. Using the vector autoregression (VAR) model and interbank rate as an indicator of monetary policy stance, the results showed that the size of dollarisation could influence the outcome of monetary policy, though the impact was small. This was evident from the output equations, that inflation did not respond in the first month and responded negatively in the second month. However, from the third …

Interest Rate Dynamics And Real Output Behaviour In Nigeria: A Simulation Analysis, S. Rapu, G. Sanni, D. Penzin, N. Nkang, P. Golit, H. Okafor, E. Ibi

Economic and Financial Review

The declining output growth observed from the second quarter of 2014, which led to calls for a more expansionary monetary policy despite rising inflationary pressure, necessitated a reassessment of the impact of interest rate on real output growth in Nigeria. Using a Bayesian Vector Autoregressive (BVAR) model and quarterly data from 2000:Q4 to 2015:Q3, the effect of monetary policy transmission (interest rate dynamics) on real output performance was estimated. Although results of the simulation analysis were somewhat mixed, those of the impulse response functions indicated that positive shocks to monetary policy rate (MPR) produced a negative and small impact on …

Savings, Net Foreign Assets And Current Accounts Dynamics In Subsaharan Africa, A. I. Adeleke, W. Ohemeng, K. Ofori-Boateng

Economic and Financial Review

A profile of the current account balance in sub-Sahara Africa (SSA) shows that many countries in the region have consistently experienced current account deficits, dwindling savings and diminishing net foreign assets. These macroeconomic variables convey important information to economic agents about the health of a nation. The relationships among these three important variables in terms of short-run and long-run dynamics are cloudy in the literature. Therefore, this study examined the long-run and short-run dynamics of savings, net foreign assets and current account balance in subSaharan Africa. Utilising panel econometric techniques with annual data from 38 countries in SSA for the …

A Dynamic Stochastic General Equilibrium (Dsge) Model Of Exchange Rate Pass-Through To Domestic Prices In Nigeria, M. A. Adebiyi Dr, C. N. Mordi Dr

CBN Occasional Papers

This paper employed a Bayesian framework of DSGE model to estimate the pass-through effect of exchange rate to domestic inflation in Nigeria, using quarterly data for the period 1990 to 2011. The response of inflation rate to exchange rate shocks was found to be positive and statistically significant in the short-run. The pass-through was small and incomplete with almost zero in quarter 1 (0.09), rose to 0.18 in quarter 2 and declined to 0.07 and 0.01 in quarters 3 and 4, respectively. These findings were lower than those obtained elsewhere by other authors. The low pass-through reported in this study …


The Impact Of Lending Rate On The Manufacturing Sector In Nigeria, D. B. Akpan, D. J. Yilkudi, D. C. Opiah Mar 2016

The Impact Of Lending Rate On The Manufacturing Sector In Nigeria, D. B. Akpan, D. J. Yilkudi, D. C. Opiah

Economic and Financial Review

The study investigates the impact of lending rate on output of the manufacturing subsector using the Vector Error Correction Model (VECM) and annual data from 1981- 2014. The empirical results indicated that high lending rate had negative impact on manufacturing output in the long-run. This suggests that increase in lending rate undermines manufacturing output, thus retarding growth in the real sector. Specifically, the estimates revealed that a 1.0 per cent increase in lending rate reduces manufacturing output by 0.03 per cent. The study, therefore, recommends the implementation of investment friendly policies that narrows the lending rate by the deposit money …

Building Dynamic Stochastic General Equilibrium Models For Monetary Policy Analysis, Charles N. O. Mordi, Michael A. Adebiyi

Economic and Financial Review

Dynamic Stochastic General Equilibrium (DSGE) models are powerful tools that provide a coherent framework for policy discussion and analysis. In principle, they can help to identify sources of fluctuations, answer questions about structural changes, help to forecast and predict the effect of policy changes, and perform counterfactual experiments. Against this background, this paper aims at providing an insightful discussion on DSGE models by developing a simplified version of the models to explain the behavior of key macroeconomic variables in Nigeria namely: the growth rate of gross domestic product (GDP), headline inflation, exchange rate and the monetary policy rate. The estimated …

Estimating A Small-Scale Macroeconometric Model (Ssmm) For Nigeria: A Dynamic Stochastic General Equilibrium (Dsge) Approach, Charlse N.O Mordi, Michael A. Adebiyi

CBN Occasional Papers

This paper attempts to develop a small scale macroeconometric model for the Nigerian economy using dynamic stochastic general equilibrium (DSGE) methodology. Particular attention is paid to using impulse responses to explain the dynamic properties of the model. This model incorporates expectation as an anchor in the forward-looking monetary policy objective of the Central Bank of Nigeria (CBN). It captures most of the channels through which policymakers believe monetary policy can influence a small open economy with a managed floating exchange rate. The model was taken to the data by means of Bayesian estimation with the following major findings. First, although …
