Determinants of inflation in Nigeria: a co-integration approach

Impact of imports and exports on inflation and how to encourage inflation-reducing factors in Nigeria

This study examines the factors affecting inflation in Nigeria, where continuous increases in prices are among the most serious economic problem in the country. Considering the urban, rural and combined consumer price index in Nigeria, the paper shows that all components of price index rose at generally higher rate than previous years. However, the author argues that inflation in Nigeria can be curtailed if factors that increase it are dealt with.

The study finds that: 

  • the previous total export is to have a negative impact on current inflation
  • particularly, lagged crude oil export has notable negative impact on inflation
  • on contrary, the previous total import is to exert a positive effect on inflation rates
  • lagged interest rate is to reduce inflation rates

The paper concludes the factors that reduce inflation should be encouraged as this might lead to price stability or price reduction in Nigeria. Furthermore, the following policy measures are recommended:

  • policies that will set the interest rate to a level at which it will encourage investment and increase in production level could be institutionalised
  • importation must be reduced by probably encouraging consumption of locally made items
  • exchange rate system should be maintained at a level that will not impose threat on the Nigeria economy, not too high nor too low
  • domestic consumption of petroleum product should be focused, not only exportation that has the tendency of depleting oil levels
