Abstract:

This paper investigates the impact that exchange rate can engender upon the linkage between public- private and economic growth. Data on public investment (Gross Fixed Capital Formation-Public) and private investment (Gross Fixed Capital Formation- Private) along with the exchange rate were sourced from World Development Indicators (WDI) 2020. The study adopted the Auto Regressive Distributed Lag (ARDL) model for its estimation techniques. The result shows no significant impact of exchange rate on both the private and public investment for the study period in the long and short runs. However, the public investment has a negative and statistically significant relationship with economic growth in the long run as well as in the short run. The Federal Government of Nigeria is advised to increase infrastructural investments as a means of correcting the negative trend
