Full Implementation in Sequential Information Design

This paper studies the full implementation in sequential information design (Doval and Ely (2020)) in which the designer can construct the extensive form as well as the information struc- ture. In this framework, I characterize the optimal outcome under full implementation when players and the designer have a supermodular payoff function with natural set of assumptions. In particular, I show that the optimal fully implementable outcome is approximately equivalent to the optimal outcome under partial implementation. Moreover, this outcome is also same to the best partially implementable outcome in static information design.
