It is widely held that under ordinal utility, utility differences are ill-defined. Allegedly, for these to be well-defined (without turning to choice under risk or the like), one should adopt as a new kind of primitive quaternary relations, instead of the traditional binary relations underlying...

The paper investigates firm managers’ strategic disclosure interactions of quantitative value estimates when facing a rationally inattentive trader who also gathers qualitative information. Considering a model with two firms and using the Kyle (1985) model to price each firm’s securities, I...

Third political parties are influential in shaping American politics. In this work we study the spread of a third party ideology in a voting population where we assume that party members/activists are more influential in recruiting new third party voters than non-member third party voters. The...

The theory of agency, which has seen many recent applications in the social sciences and management literatures, is essentially a theory of failures: It seeks to understand the problems created when one party attempts to control another's behavior, given that control is costly and it often does...

An extension of Condorcet's paradox by McGarvey (1953) asserts that for every asymmetric relation R on a finite set of candidates there is a strict-preferences voter profile that has the relation R as its strict simple majority relation. We prove that McGarvey's theorem can be extended to...

If each member of a group assigns a certain probability to a hypothesis, what probability should the collective as a whole assign? More generally, how should individual probability functions be merged into a single collective one? I investigate this question in case that the individual...

We discuss sincere voting when voters have cardinal preferences over alter- natives. We interpret sincerity as opposed to strategic voting, and thus define sincerity as the optimal behaviour when conditions to vote strategically vanish. When voting mechanisms allow for only one message type we...

In this paper we characterize choice behaviour that picks the second largest element if there is a uniquely largest; otherwise, the largest elements are picked. Having defined our choice function, we offer a complete characterization of the latter in terms of pure choice function conditions....

We investigate experimentally the effect of consultation (unincentivized advice) on choices under risk in an incentivized investment task. We compare consultation to two benchmark treatments: one with isolated individual choices, and a second with group choice after communication. Our benchmark...

Juries charged with evaluating economic policy alternatives are the focus of this study. The recruitment and management of juries is a principal–agent problem involving the design of incentive mechanisms for participation and truthful revelation of values. This paper considers a simple general...
