An OLS Approach to Modelling the Determinants of Private Investment in Ghana

Open access
After independence, most developing countries embraced the development paradigm of import substitution. Nevertheless, in the 1980s, there was a shift in development paradigm from import substitution to the private sector-led development strategy to boost growth in developing countries. The study analyses the determinants of private investment in Ghana using a time series data from 1980 to 2010 with the aid of multiple linear regression model. It was revealed that factors that have a significant impact on private investment in Ghana were public investment, credit supply to the private sector, external debt, openness of the economy, corporate tax and democracy. Nevertheless, variables like: GDP growth, real interest rate, inflation and real exchange rate were not statistically significant. The study therefore recommends a tighter fiscal policy to reduce the crowding out effect on private investment. Foreign trade and trade liberalization must be encouraged to ameliorate private investment in Ghana.
