Deliberating Collective Decisions
We present a dynamic model of sequential information acquisition by a heterogeneous committee. At each date agents decide whether to vote to adopt one of two alternatives or continue to collect more information. The process stops when a qualified majority vote for an alternative. Three main insights emerge from our analysis and match an array of stylized facts on committee decision making. Firs...
متن کاملCostly Verification in Collective Decisions∗
We study how a principal should optimally choose between implementing a new policy and maintaining the status quo when the information relevant for the decision is privately held by agents. Agents are strategic in revealing their information, but the principal can verify an agent’s information at a given cost. We exclude monetary transfers. When is it worthwhile for the principal to incur the c...
متن کاملGenetic bases of collective decisions in Drosophila
Fruit flies (Drosophila melanogaster) hatch and feed collectively in a single host fruit during their entire larval development. Larvae exhibit two distinct foraging strategies attributed to variations in a single polymorphic foraging gene: the 'rovers' (forR/R) cover larger distances and are more likely to leave a food patch, whereas the 'sitters' (forR/s) cover smaller distances and stay long...
متن کاملThe option to wait in collective decisions∗
We analyze a model in which voters learn over time their preferences regarding an irreversible social decision. Voters can either implement the project in the first period, or they can postpone the decision to the second period. We analyze the effects of different majority rules. We show that individual first period voting behavior may become “less conservative” under supermajority rules, and t...
متن کاملThe Linking of Collective Decisions and Efficiency
For groups that must make several decisions of similar form, we define a simple and general mechanism that is designed to promote social efficiency. The mechanism links the various decisions by forcing agents to budget their representations of preferences so that the frequency of preferences across problems conforms to the underlying distribution of preferences. We show that as the mechanism op...
