Abstract

This study considers the consequences of external loan on capital investment in Nigeria. Data for the study have been collected from the World Bank and Central Bank of Nigeria Statistical Bulletin, 2018 edition. The variables on which data are sourced include government capital expenditure, external debt accumulation, debt servicing cost, inflation rate, and exchange rate. Government capital expenditure is the dependent variable, while external debt accumulation and debt servicing cost are the key independent variables. Inflation and exchange rates are used as the moderating variables. The scope of the study covers the period from 1996 to 2018 and the data are analysed using the ordinary least squares multiple regression method. The regression results indicate that external debt has a significant negative impact on capital investment while debt servicing cost has a strong and significant positive effect on capital investment. Under this circumstance, the controlling variables are not significant in influencing capital investment. Hence, the study suggests more focus on profitable capital investments if external borrowing must be embarked upon. The need for the development of untapped natural resources, establishment of industries and revival of abandoned industries to boost debt repayment has been emphasized. The study also strongly recommends that the existing governments (state and federal) should endeavour to complete capital projects of past administrations in order to drive the economy and to avoid wastage of financial resources including the borrowed funds.
