We study how education system impacts endogenous formation of human capital, trade patterns and income inequality. We construct the model of education choice with modifying 3 sector occupation choice model. Over the countries, education systems are characterized by education cost and efficiency of education. Upon trade liberalization from autarky state, country with higher human capital has comparative advantage in the innovative sector while the other country specializes in the routine sector, with obtaining fixed and lower returns. This specialization pattern promotes more education acquisition in the former country in expense of higher income inequality.
