CBN Monetary Policy and Inflation Nexus in Nigeria: An empirical approach (Published)

The study explored monetary policy effect on inflation stabilization in Nigeria. Increasing levels of indebtedness may have reduced the fiscal space for fiscal policy intervention and this leaves monetary policy as the real tool of choice for macroeconomic stabilisation. The question we need to ask then is, how effective is this tool of choice? Monthly time series data from 2009-2018 were used in estimating the model. The ADF test for the stationarity, the johansen cointegration test and the vector error correction model were utilized in testing the variables. The findings from the unit root test did indicate stationarity at first difference 1(1). The cointegration (Johansen) test indicates that there was a nexus linking inflation and all the regressors adopted in the long term. The result of the VECM for the two estimated models shows a self-equilibrating mechanism of 14 per cent and 32 per cent for the first and second models respectively. The findings further reveal that the variables; liquidity ratio, policy rate (MPR), exchange rate, reserve requirement and treasury bills rate all had an effective impact on the inflation rate and that that effect was very significant.  Hence, the CBN’s monetary policy shocks do seem to have the expected traction on the Nigerian economy. The results make it pertinent for the CBN to utilize all the policy measures adopted in order to keep inflation within acceptable thresholds and prepare to keep inflation within the targeted range of 6-9 per cent, no matter the anticipated or unanticipated strong head winds.

Implications of Savings and Investment on Economic Growth in Nigeria (Published)

The implication of savings and investment on economic growth is mixed and controversial both theoretically and empirically. There is large empirical literature which examines the relationship between savings and economic growth in Nigeria. There is also a considerable literature which looks at the relationship between economic growth and investment. However, little attention has been given to examining the implications of savings and investment on economic growth in Nigeria. The aim of this paper is to evaluate the implications of savings and investment on economic growth in Nigeria using ordinary least square regression. Results for ADF and PP unit root tests show that all variables under consideration are I(1). The study also revealed that there is long run relationship between savings, investment and economic growth in Nigeria. The result of the regression indicates that change in gross domestic savings movements has negative and significant effect on the change in economic growth in Nigeria and that the change in gross domestic investment has positive and significant effect on the change in the Nigerian economic growth. We therefore recommend that government should set a sound and fertile environment in order to foster domestic saving that will help to increase the level of economic growth in Nigeria
