Abstract
 
As being  experienced in many developing countries,  Nigeria has been  experiencing 
confirmed capital flight which has been a  problem believed  to have  adversely  affected 
domestic investment. The existence of this problem is further accentuated by the financial 
globalisation process which has enabled capital to flow more freely than before between 
countries of the world. This study examined  the  relationship between  capital flight in 
Nigeria and investment during the period of financial globalisation with data from 1970 to 
2007. The main variables used were exchange rates, investment, Kaopen, financial savings, 
external reserves and interest rate differential among others. Ordinary Least Square (OLS) 
technique is used in determining the significant variables in investment  and financial 
globalisation, while Vector Error Correction Mechanism (VECM) was adopted to determine 
the long-term relationship between investment and capital flight.  The study finds that the 
rate of exchange is significant in investment and financial globalisation but not significant 
in World Bank’s and Dooley’s estimates of capital flight. The different estimates of capital 
flight do  not significantly  impact negatively against  investment though it has a long-term 
negative impact on external reserves of the country. The Dooley’s definition of capital flight 
is  found to more significant in the Nigeria case than the World Bank’s as its impact is 
negative on the investment, though not significant. This signifies the role of errors and 
omissions in distorting  the estimates of capital flight in Nigeria.   The other determinant of 
capital flight  is the  interest rate differential in the co-integrating equation. Unusually, the 
Kaopen measure is significant in the Nigeria’s financial globalisation scenario, which calls 
for careful foreign exchange rate management to determine the rate of the exchange.  The 
study recommends a cleaner  floating of  the domestic currency to reduce capital  flight, the 
improvement of the business environment and an increase in the autonomous investment by 
both public and private sectors in the economy to induce other domestic investments, which 
will facilitate inflow of capital.
