内容刚要：

Methods and mechanisms for sustaining cooperation in Prisoner’s Dilemma settings have been of tremendous interest across disciplines. In this study, we present a new mechanism for promoting cooperation via self-commitment. Our experimental results show that the self-commitment mechanism successfully separates cooperators from defectors ex-ante, with an overall take-up rate of over 50 percent. In addition, around 80 percent of those taking up the commitment subsequently chose cooperation. These results suggest that our mechanism could be useful, both in sorting individuals based on their preferences for cooperation, as well as in promoting socially efficient outcomes.

【讲座 二】Reference Points for Effort Provision in an Experimental Labor Market

主讲人介绍：

Performance benchmarks or reference points, play an important role in motivating workers’ efforts by setting targets for achievements. Despite their widespread use in most workplace settings, relatively little is known about which types of performance benchmarks are most effective as motivators for workers, and how to optimally set benchmarks based on workers’ past performances and beliefs. We form hypotheses based on behavioral principles and test them using information transfer tasks which require patience, cognitive processing, self-control and accuracy, in the online labor market Mechanical Turk. We test the effects of high and low non-monetary performance targets and their interaction with self-evaluations. We also test positive and negative framing of benchmarks, and the relative effects of socially-based benchmarks compared to individual benchmarks among optimistic and pessimistic workers. Our study contributes to the understanding of setting performance targets in firms and in the larger economy.
