The lack of hard evidence in allegations about sexual misconduct makes it difficult to separate true allegations from false ones. We provide a model in which victims and potential libelers face the same costs and benefits from making an allegation, but the tendency for perpetrators of sexual misconduct to engage in repeat offenses allows semiseparation to occur, which lends credibility to such allegations. Our model also explains why reports about sexual misconduct are often delayed, and why the public rationally assigns less credibility to these delayed reports.

Professor Wing SUEN was educated at The University of Hong Kong (HKU). He obtained his Ph.D. at the University of Washington. After doing post-doctoral research at the University of Chicago, he returned to his alma mater in 1989 and is now Chair of Economics at HKU Business School. He had also held research or teaching positions at Simon Fraser University, Harvard University, and the Chinese University of Hong Kong.
Wing’s research interests center around applied microeconomic theory. He has done some work on efficiency and early contracting in two-sided matching markets. One of his current research areas looks at the transmission of information across individuals with divergent beliefs and motives. An application that is close to the heart of the academician is the issue of grade inflation in higher education. He argues that the college professor, in playing the dual role of advocate and judge for his students, is trapped into an inefficient equilibrium in which grades are too high.
Another example of this line of work explores the structure of social networks. Individuals with opposing viewpoints tend to believe that the other party is uninformed or misinformed. If people form social ties in order to obtain more information, they will rationally choose to be associated with like-minded peers. Will there be an equilibrium in which people with different viewpoints are segregated from one another? What are the consequences of this group formation process for the evolution of social beliefs?
Wing also maintains an interest in the labor market of Hong Kong. He is an associate editor of the Pacific Economic Review and is program leader of the Human Resources Research Program of the Hong Kong Institute of Economics and Business Strategy. His current work in this area focuses on the effects of public housing on internal migration, travel-to-work patterns, and labor supply decisions.

An agent performing risky experimentation can benefit from suspending it to learn directly about the state. ‘Positive’ information acquisition seeks news that would confirm the state that favours experimentation. It is used as a last-ditch effort when the agent is pessimistic about the risky arm before abandoning it. ‘Negative’ information acquisition seeks news that would demonstrate that experimentation is futile. It is used as an insurance strategy to avoid wasteful experimentation when the agent is still optimistic. A higher reward from risky experimentation expands the region of beliefs that the agent optimally chooses information acquisition rather than experimentation.
