In a model of majority voting with common values and costly but voluntary participation, we show that in the vicinity of equilibrium, it is always Pareto-improving for more agents, on the average, to vote. This demonstrates that the negative voting externality identified by Borgers(2001) in the context of private values is always dominated by a positive informational externality. In addition, w...

We present three new voting schemes for multi-classifier biometric authentication using a reliability model to influence the importance of each base classifier’s vote. The reliability model is a metaclassifier computing the probability of a correct decision for the base classifiers. It uses two features which do not depend directly on the underlying physical signal properties, verification scor...

| This paper examines and compares the merits and demerits of the national (global) and the regional (partitioned) voting system where the national voting selects a candidate directly by a simple majority of the entire voting population of the nation while the regional voting chooses the candidate indirectly by a majority of the regions, not by the majority of the entire votes. And we demonstra...

In a symmetric information voting model, an individual (information controller) can influence voters’ choices by designing the information content of a public signal. We characterize the controller’s optimal signal. With a non-unanimous voting rule, she exploits voters’ heterogeneity by designing a signal with realizations targeting di↵erent winning-coalitions. Consequently, under simple-majori...
