Roland Cheo教授的报告主题为:Contributing Time and Effort in Public or Minding My Business in Private? Answers from a Real Effort Public Goods Task:    
    This paper therefore provides a new experimental design which de-emphasizes monetary contributions into the public account, while retaining the essential features of the public goods game. Instead of the stylised task of the public goods game, we base our experiment on one real effort cognitive task: solving a jigsaw puzzle, in order to see how contributions vary according to the level of cognitive effort needed to render help to strangers.
    Our main results show that contributions hurt performance in the private account, while helping others complete the tasks faster.This gives evidence that people are willing to help others to their own detriment. This observation cannot be gleaned from the standard public goods game alone because the private account in the standard public goods game is a guaranteed amount, and contributions may be motivated as an act of charity above and beyond this minimum amount. As task complexity increases, this helping behavior in the real task persists and even strengthens.

李菁萍助理教授的报告主题为:Do unto others as others do unto me?: voice matters:

    Do we penalise an innocent outsider when we have been unfairly dealt with? On the other hand, do we reward outsiders when we have been treated well? In this paper, we investigate the effect of voice on the decisions of recipients who become dictators in a two-stage three-person dictator game. In the first stage, the randomly assigned dicator shares a pie with a randomly assigned recipient. This recipient then plays the role of ‘sender` in the second stage dictator game with an outsider. We find that these recipients-turned-dictators` transfers are not significantly different from the dictators in the first stage, though they are highly correlated. When recipient in the first stage, after receiving their transfers are allowed to leave a private message to their dictators, when it is their turn to become dictators, the amount they transfer increases significantly. Further evidence shows that having voice mainly impacts the future decisions of recipients who received a low amount in the first stage. Voice also reduces the level of correlation between first stage dictator`s and the second stage recipient-turned-dictators` transfers.
