We study a Condorcet jury model where voters are driven by instrumental and expressive motives. We show that arbitrarily small amounts of expressive motives significantly affect equilibrium behavior and the optimal size of voting bodies. Enlarging voting bodies always reduces accuracy over some region. Unless conflict between expressive and instrumental preferences is very low, information does not aggregate in the limit, and large voting bodies perform no better than a coin flip in selecting the correct outcome. Thus, even when adding informed voters is costless, smaller voting bodies often produce better decisions. . Adapted from the source document.

We study vote buying by competing interest groups in a variety of electoral and contractual settings. While increasing the size of a voting body reduces its buyability in the absence of competition, we show that larger voting bodies may be more buyable than smaller voting bodies when interest groups compete. In contrast, imposing the secret ballot is an effective way to fight vote buying in the presence of competition, but much less so in its absence. Regardless of competition, the option to contract on both votes and outcomes is worthless, as it does not affect buyability compared to contracting only on votes. The option to contract on votes and vote shares, on the other hand, is extremely valuable: it allows the first mover to effectively nullify competition and obtain its preferred policy at almost the monopoly cost.

We study a model in which voters choose between two candidates on the basis of both ideology and competence. While the ideology of the candidates is commonly known, voters are imperfectly informed about competence. Voter preferences, however, are such that ideology alone determines voting. When voting is compulsory, the candidate of the majority ideology prevails and this may not be optimal from a social perspective. However, when voting is voluntary and costly, we show that turnout adjusts endogenously so that the outcome of a large election is always first-best. Adapted from the source document.
