A note on the long-run determinants of economic growth

Variable selection is the issue of major concern in practical regressions. This note provides a simple and efficient method to examine the robustness of predictor variables in cross-country economic growth models. Our results confirm the general findings of Sala-i-Martin <italic>et al.</italic> (2004), indicating the importance of a number of same predictor variables. In addition, we also identify that some other variables are associated with economic growth.
