I accomplished the contents of my theoretical research plan by incorporating habit formation and parental altruism, and investigated the theoretical conclusions by using empirical analysis.In my paper "Thankworthy Parental Altruism and Children' s Habit-Formation" which is based on the joint research with Professor Ikeda, we propose a model of parental altruism in relation with child habit formation, where children are unaware of their developing habits while young, and become cognizant of them only on growing up. We show that an altruistic mother (i) maintains the amount of income transferred to her child lower than the child would desire and (ii) reduces further income transfer upon an exogenous increase in the child's performance of a particular habit. The child, when grown, may end up grateful for the small income transfer if the mother is sufficiently rich and altruistic : when evaluated by the realized habitual preferences, a small income transfer leads to greater child welfare than the greater income transfer preferred by the child would have generated. This implies that parents from richer families, ceteris paribus, tend to guard against their children's profligacy.In another joint research "Strict Parents Come From Wealthy Families : An Empirical Study", We examine and verify the hypothesis from our theoretical model that people who are aware of habit tend to strictly upbring their children if they are from wealthy family. Using the data from "Preference Parameters Study of Osaka University" in Japan, we find that there are significantly positive relations between respondents' strict upbringing practices and their living standards when 15 years old in the case that respondents are aware of habit. This empirical result is consistent with our theoretical prediction.

我将习惯形成和父母利他主义结合起来，完成了我的理论研究计划的内容，并通过实证分析对理论结论进行了考察。在我与池田教授共同研究的论文《值得商榷的父母利他主义与儿童的习惯形成》中，我们提出了一个父母利他主义与儿童习惯形成的关系模型，孩子们在小的时候没有意识到他们正在形成的习惯，只有在长大后才意识到这些习惯。我们表明，一个利他主义的母亲（一）保持收入转移到她的孩子低于孩子的愿望，（二）减少进一步的收入转移后，外源性增加的孩子的表现的一个特定的习惯。如果母亲足够富有和无私，孩子长大后可能会对小额收入转移表示感激：当根据已实现的习惯性偏好进行评估时，小额收入转移会比孩子更喜欢的更大收入转移产生更大的儿童福利。在另一项合作研究“严格的父母来自富裕家庭：一项实证研究”中，我们检验并验证了我们的理论模型假设，即如果他们来自富裕家庭，那么意识到习惯的人倾向于严格地抚养他们的孩子。利用日本大坂大学的“偏好参数研究”的数据，我们发现，在被调查者意识到习惯的情况下，被调查者的严格教养方式与他们15岁时的生活水平之间存在显著的正相关。这一实证结果与我们的理论预测是一致的。
