This paper analyzes the optimal size of a deliberating committee where (i) there is no conflict of interest among individuals and (ii) information acquisition is costly. The committee members simultaneously decide whether to acquire information, and then make the ex-post efficient decision. The...

We consider a committee voting setup with two rounds of voting where committee members who possess private information about the state of the world have to make a binary decision. We investigate incentives for truthful revelation of their information in the first voting period. Coughlan (2000)...

This paper provides new empirical evidence on policy-makers' voting patterns on interest rates. Applying (pooled) Taylor-type rules and using real-time information available from published inflation reports and voting records, the paper tests for heterogeneity among committee members in three...

We study the effect of public information on collective decision-making in committees, where members can have both common and conflicting interests. In the presence of public information, the simple and efficient vote-your-signal strategy profile no longer constitutes an equilibrium under the...

We examine the consequences of vote transparency in committees whose members fear being blamed by partisan observers for casting an unfavorable vote. We show that such social pressure, like optimal taxation, can improve the collective decision by mitigating a voting externality. Hence,...

How does salient public information affect voters' behavior? In a majoritarian voting game with common preferences, rational voters could use public information as an information device (depending on accuracy) or as a coordination device (regardless of accuracy). A simple lab experiment...

We analyze a committee decision in which individuals with common preferences are uncertain which of two alternatives is better for them. Members can acquire costly information. Private signals and information choice are both continuous. As is consistent with Down's rational ignorance hypothesis,...
