Trade Liberalization and Economic Growth: The Role of Regulatory Policies

Abstract

This paper investigates the relationship between international tradeliberalization and economic growth with a focus on the role of regulatorypolicies in a selected sample of sixteen sub-Saharan Africa (SSA) countries.While international trade liberalization refers to the removal ofbarriers to international trade, regulatory policies refer to the improvement ofcredit, labour and product markets in a country. Using panel data, the study applies the Instrumental Variables (IV) and the Generalized Method of Moments (GMM)methodologies to deal with the problem of endogeneity. The results show thatbetter regulatory policies significantly contribute to economic growth.Further, international trade liberalization works well when regulatory policiesare improved in tandem with liberalization. Thisimplies that less regulated countries benefit more from international tradeliberalization than heavily regulated countries. Therefore, improvements in policies that regulate credit, labour and product markets willenhance the gains from international trade liberalization in Sub-Saharan Africa. Further, the results show that accumulation of physical capital contributes to economic growth. Thus, Sub-Saharan African countries should reform their regulatory policies as they continue to deepen international trade liberalization.
