  International trade has been in the forefront of economic development and
growth debates. Trade openness, its definition, scope, and impacts have also
been studied numerously. Tariff has been dubbed as negative influencer of
economic growth as per conventional wisdom and most empirical studies. This
paper empirically examines relationships among trade openness as trade share to
GDP, import tariff rate and economic growth. Panel dataset of 11 G-20 member
countries were selected for the study. Results found a positively significant
correlation between trade openness and economic growth. Tariff has negatively
significant correlation with economic growth in lagged model. OLS and panel
data fixed-effects regression were employed to carry out the regression
analysis. To deal with endogeneity in trade openness variable, a 1-year lag
regression technique was conducted. Results are robust and significant. Policy
recommendation suggests country specific trade opening and tariff relaxation.
