The role of an effective regulatory regime in promoting economic growth and development and therefore international business has generated considerable interest among researchers and practitioners in recent years. In particular, building effective regulatory structures in developing countries is not simply an issue of the technical design of the most appropriate regulatory instruments, it is also concerned with the quality of supporting regulatory institutions and capacity. Many of the institutions that support markets are publicly provided and the effectiveness of these regulatory institutions can be expected to be an important determinant of how well markets function. This paper explores the role of regulation in affecting economic outcomes using an econometric model of the impact of regulatory governance. More precisely, it assesses through econometric modelling the impact of variations in the quality of regulatory governance on economic growth. Proxies for regulatory quality are included as determinants of economic growth. The results based on two different techniques of estimation suggest a strong causal link between regulatory quality and economic performance. The results confirm that "good" regulation is associated with higher economic growth, which in turn is conducive to the expansion of international business.
