我们分析了一个对称模型的选举中,选民是不确定的两个选择是可取的。每个投票者都必须付出一定的代价来获得关于备选方案的信息。我们表明,通过专注于无偏投票策略,一般的对称信号结构可以退化为一个双信号模型。此外,我们还证明了对于任何无偏投票均衡序列,如果在无信息时信息成本函数的二阶导数为零,则选择所需替代方案的概率收敛于1,即孔多塞陪审团定理成立。否则,这个概率会收敛到小于1的某个值;也就是说,“理性无知”假设是有效的。版权所有2008 Blackwell Publishing,Inc.
We analyze a symmetric model of an election in which voters are uncertain about which of two alternatives is desirable for them. Each voter must incur some cost to acquire information about the alternatives. We show that by focusing on unbiased voting strategies, general symmetric signal structures can be degenerated to a two-signal model. In addition, we show that for any sequence of unbiased voting equilibria, if the second-order derivative of the information cost function at no information is zero, then the probability of electing the desirable alternative converges to one, that is, the Condorcet Jury Theorem is valid. Otherwise, this probability converges to some value less than one; that is, the "rational ignorance" hypothesis is valid. Copyright 2008 Blackwell Publishing, Inc..
