The study investigated the effects of deficit financing on the Nigerian economy using data that covered 41 years (1981 to 2021). Real gross domestic product (RGDP) was the dependent variable, while government budget deficit financing disaggregated into different sources of budget deficit financing represented the explanatory variables. The ordinary least squares (OLS) regression method was used for the tests and analyses. Results established that both non-bank public sources of deficit financing and banking system sources of deficit financing had positive and significant effects on growth. However, non-bank public deficit financing positively led the Nigerian economy and was followed by banking system deficit financing. Both ways and means and external deficit financing sources were negative and insignificant in influencing the Nigerian economy. Ways and means were third while external deficit financing was fourth in descending order of influence on RGDP growth. The study further applied the Augmented Dickey-Fuller (ADF) approach to unit root tests and observed that the variables were integrated at both levels and first difference, leading to the application of the Autoregressive Distributed lag (ARDL) approach to data estimation. The ARDL bounds tests showed that the model specified for the study followed a long-run path and that a long-run relationship existed between the dependent variable and the explanatory variables. The estimation of the long-run and error correction estimation indicated that the independent variables had a time-varying effect on the real gross domestic product of Nigeria. That ARDL estimation of the error correction mechanism also showed that RGDP adjusted rapidly to short-run discrepancies in the long run. Finally, the error correction mechanism showed that external sources of budget deficit financing, non-banking system public deficit financing, ways and means source of deficit financing, gross capital formation, real interest rate and exchange rate, all had robust effects on growth, though with varying directions of influence. Based on the foregoing, the study has recommended deficit financing, more especially non-bank public deficit financing and banking system deficit financing as better options for attaining the much desired rapid and sustainable economic growth of Nigeria as they have been proven to be non-inflationary in practice compared to ways and means and external source of deficit financing over the years.
