In this paper, we model the relationship between fiscal deficit and inflation for Nigeria using annual data from 1980 to 2016. We employ the linear ARDL approach and account for structural breaks using the Bai and Perron (2003) test that allows for multiple structural changes in regression models. The paper finds that the fiscal deficit is a major determinant of inflation along with other macroeconomic factors considered in the study. However, we observe that it may be necessary to pretest for structural breaks when modelling the relationship between the fiscal deficit and the price level, as it performs better than when structural events are not considered. The results imply that a fiscal management process that does not encourage increased revenue and reduce fiscal deficits will further worsen the level of inflation in the country.

In this paper, we model the relationship between fiscal deficit and inflation for Nigeria using annual data from 1980 to 2019.
