Recently, the lectures on "New Horizon of Discipline" sponsored by the Youth League Committee of the School of Economics and undertaken by the Economics Elementary School were successfully held at the Round Stage of the School of Economics. Na Yi, a scholar at the center and deputy director of Nankai Behavioral Economics Research Center, was invited as a guest to give a lecture on situational experience and special topic of behavioral economics around the theme of "Understanding' wrong behavior'-from neoclassical to behavioral economics". Students from many colleges in our school participate in this activity.
