主 题：Designing Fair and Effective Ways to Fund Public Goods
主讲人：陈礴 英国华威大学教授
主持人：张显东 复旦大学管理学院教授
Abstract：How can a community decide whether to fund a shared project—such as a public facility, digital platform, or security upgrade—when everyone benefits but individuals value it differently? And how can we do this in a way that is fair, transparent, and doesn’t run a deficit?
This talk presents new research on how to design simple, truthful, and budget balanced rules for deciding when to provide a public good and how to split its cost. We show that the best such rules take a very intuitive form: each person is asked to cover a fixed “share” of the cost, and the project goes ahead only if everyone’s willingness to pay meets or exceeds their share. We explain when equal cost shares make sense, when they do not, and how these rules behave as the group becomes large.
We also discuss what happens when we slightly relax the requirement of breaking even exactly. Allowing even a small amount of financial flexibility can dramatically improve outcomes—bringing us much closer to what a fully efficient system would choose.
The seminar will outline the main ideas without technical detail, highlighting the economic intuition behind fairness, incentives, and feasibility in shared project decisions.
