摘要

An empirical investigation of the contribution of agriculture, petroleum, human capital to the economic growth in Nigeria were carried out in this paper by employing cointegration test, Granger causality test and ordinary least square techniques, using the data of annual time series for the period 1970-2012. The findings reveal the existence of 3 cointegrating vectors which show a long-run relationship among the variables in the series used. The Granger causality test shows that there is a bi-directional causality among the variables. The OLS results show that agriculture and petroleum contribute to output growth positively and significantly, while human capital contributes to output growth negatively but insignicantly. Thus, if a policy aims at sustaining a high rate of economic growth in Nigeria, the priority should be given to the development of human capital in the budgetary and development policies. An effective coordination of these variables and a good policy mix to avoid lopsidedness will ensure a high and sustainable economic growth since there is a bi-directional causality between these variables.
