The current note clarifies why, in committees, the prior probability of a correct collective choice might be of particular significance and possibly should sometimes even be the sole appropriate basis for making the collective decision. In particular, we present sufficient conditions for the...

This paper compares the determination of investment criteria in single- and multi-member organizations. Individual decisional skills are assumed to be endogenous variables that depend on the investment criteria. Our main result specifies the condition that determines the relationship between the...

The current note clarifies that Condorcet Jury Theorem cannot be generalized to the extended setting where individual decisional skills are not assumed to be exogenous parameters even when these skills are homogeneous. This is true when skills are determined endogenously either by a central...

Committee decision making is examined in this study focusing on the role assigned to the committee members. In particular, we are concerned about the comparison between committee performance under specialization and non-specialization of the decision makers.
