We consider a problem of allocating multiple identical objects to a group of agents and collecting payments. Each agent may receive several objects and has quasi-linear preferences with a submodular valuation function. It is known thatWalrasian mechanisms are manipulable. We investigate the...

We consider common-value voting when a variable that is independent of the payoff-relevant state determines the meaning and precision of voters' private signals about the payoff-relevant state. Multiple senders sharing the same objective as the voters receive noisy signals that are contingent on...

Firms sometimes have problems with their products or management systems, problems that can lead to catastrophic events. Often, workers in such firms are aware of these problems but fail to report them to their superiors. This paper examines workers' incentives for concealing problems within an...

We consider a common-value voting in which the state of the nature is a pair of payoff-relevant state and a variable that determines the precision and the meaning of voters' private signals. Each voter receives noisy signals about both of the states. When the number of voters is sufficiently...

Developing a considered response to a question typically takes a long time, which may tempt a questionee to provide an ill-considered response. This possibility can make the questioner suspect that a prompt response is ill-considered, even if it is actually the result of deliberation. If the...
