In addition to these three variables, other variables such as annual population growth rate, inflation rate and degree of trade openness on economic growth is examined. The results suggest that the impact of the increase in the rates of these three types of taxes on economic growth is negative and significant, and for an increase in the rate of corporate tax rate, business tax rate and indirect taxes rate by 2/4 and 2/8 and 1/8 of economic growth is reduced.
