Note(s): This table depicts the dynamic panel data regression analysis using two-step system generalized method of moments (2SGMM). In the parentheses below the coefficients, the robust standard errors are shown. The symbols ***, ** and * denote statistical significance at the 1, 5 and 10% levels, respectively
