This study examined the effect of monetary and fiscal policies on price stability in Nigeria using a data-rich framework spanning from 1986-2020. The main problem with the macro-economic policies that prompted this study was the fact that despite the series of the CBN Monetary Policy Committee decisions and government tax and expenditure implementation there is apparently no useful effect on inflation (price). The study employed Auto-regression Distributed Lag (ARDL) Bound Test for Co-integration of data analysis depending upon the time series properties of the data that confer mixed order of integration in addition to the conduct of the unit root test and Error Correction Model (ECM) estimation. The ADF test revealed that LNCPI, EXR, GSDMD, GEXP, GTX and M2 were stationary at 1(1) while RIR, MPR and BOP at 1(0). Pesaran, Shin and Smith (2001) established that the ARDL bounds technique allows a mixture of 1(1) and 1(0) variables as regressors. Hence, we proceed to perform the ARDL bounds test for integration. The results of the ARDL bounds revealed that the null hypotheses were all rejected implying that a long-run effect exists among monetary and fiscal policies variables and CPI in a multivariate framework. ECM coefficient of -0.2942 conforms with expectation. Durbin-Watson statistic 0f 1-9925 revealed that the model seems not to have any case of autocorrelation. The result of our analysis shows that fiscal policy rather than monetary policy exerts a more potent effect on price stability in Nigeria. The study recommends that both monetary and fiscal policies should be complementary in order to be effective in taming inflation in Nigeria.
