An investigation into the relationship between trade openness and economic growth: A study of selected economies in the Sub-Saharan region (1990 – 2013)
Abstract
The debate of trade openness and economic growth has been studied by many researchers and
various conclusions have been made. This study attempted to add a voice to the debate by
coming up with proxy measures for trade openness. Average tariffs, tariff revenues, imports
volumes, foreign direct investment and total trade volumes were variables used to explain
economic growth.
The study employed the Random Effects Model ahead of the pooled ordinary least squares
and Fixed Effects Model owing to the results of the Poolability test, Breusch-Pagan test as
well as the Hausman test. Average tariffs, tariff revenues, foreign direct investment and total
trade volumes were found to be significant in explaining economic growth and therefore the
thrust (as suggested in the policy recommendations) was to liberalise trade in line with the
mentioned variables.
The study found that trade liberalisation spurs economic growth although it is just one piece
of the puzzle of government policies that requires other pieces (policies) to complete the
maze.
