Sequential Voting Procedures in Symmetric Binary Elections
研究对称二元选举中的序贯投票,发现同时投票的对称均衡在序贯结构中仍然成立,且序贯投票在信息聚合上并不优于同时投票。
We explore sequential voting in symmetric two‐option environments. We show that the (informative) symmetric equilibria of the simultancous voting game are also equilibria in any sequential voting structure. In unanimity games, (essentially) the whole set of equilibria is the same in all sequential structures. We also explore the relationship between simultaneous and sequential voting in other contexts. We illustrate several instances in which sequential voting does no better at aggregating information than simultaneous voting. The inability of the sequential structure to use additional information in voting models is distinct from that in the herd‐cascade literature.
