"Rewards, Badges, and Incentives" (CRCS Lunch Seminar)

Special CRCS Lunch Seminar (Wednesday, March 13, 2013) Speaker: Jon Kleinberg, Cornell University Title: Rewards, Badges, and Incentives Abstract: Many systems involve the allocation of rewards for achievements, and these rewards produce a set of incentives that in turn guide behavior. Such effects are visible in many domains from everyday life, and they are increasingly forming a designed aspect of on-line social media sites through the use of badges and other reward systems. We consider several aspects of the interaction between rewards and incentives, including a framework for reasoning about on-line user behavior in the presence of badges, and some reflections on the incentives produced by the allocation of credit in a simple model of a scientific community. The talk will be based on joint work with Ashton Anderson, Dan Huttenlocher, Jure Leskovec, and Sigal Oren.
