Furthermore, an empirical test was applied making use of statistical inferences between two averages to verify the existence of positive relations among the variables, size (barriers to entry) and the managerial return into the Brazilian market, using accounting data. The results of these tests show that the return of the bigger companies is superior to the smaller ones.
