The analysis of the effect on international income inequality and the consumption-human capital habit formation

本文采用代际重叠的分析框架，通过对消费习惯和人力资本习惯的定义，分析了国际收入不平等的影响。由此，我们可以得出以下两个结论：（1）当一个国家对父母的消费水平有强烈的期望时，国际贸易会导致人均收入水平的下降;（2）人力资本起点过低会导致国家陷入贫困陷阱，因为对高人力资本的强烈期望会导致过度的教育投资。

We use an overlapping generations framework to analyze the effect of international income inequality by formulating consumption habit and human capital one. As a result, we can derive the following two results :(i) when the country has a strong aspiration for parents' consumption level, international trade can cause the decreasing income level per capita ;(ii) starting too low human capital leads the country to a poverty trap, because an strong aspiration for high human capital create over-educational investment.
