Abstract

We study information aggregation through voting in dynamic environments. We show that the voting rule under which an informative vote is a Nash equilibrium entails a time-varying quota, which suggests that efficient information aggregation requires the use of time-varying voting rules. We also show that a time-invariant simple majority quota rule is asymptotically efficient, that is when the size of the committee tends to infinity. We discuss possible applications to the monitoring and managing of natural resources and the environment.
