The allocation of a government budget between a public good and transfers is modeled under different systems of government. The relatively even distribution of political power among groups in a democracy favors spending on nonexclusive public goods. The more concentrated pattern of political power in a dictatorship favors spending on transfers targeted to powerful groups. The hypothesis on publ...

Ludwig von Mises argues that public opinion, not the form of government, is the ultimate determinant of policy. The implication is that, holding public opinion constant, democracies and dictatorships will have the same policies—a result I call Mises’ Democracy–Dictatorship Equivalence Theorem. According to Mises, dictators have to comply with public opinion or else they will be overthrown. I ar...

The Gibbard-Satterthwaite theorem states that every non-trivial voting method between at least 3 alternatives can be strategically manipulated. We prove a quantitative version of the Gibbard-Satterthwaite theorem: a random manipulation by a single random voter will succeed with non-negligible probability for every neutral voting method between 3 alternatives that is far from being a dictatorship.

One of the core problems in multiagent systems is how to efficiently allocate a set of indivisible resources to a group of self-interested agents that compete over scarce and limited alternatives. In these settings, mechanism design approaches such as matching mechanisms and auctions are often applied to guarantee fairness and efficiency while preventing agents from manipulating the outcomes. I...

Abstract In this paper we determine the asymptotic behavior of Non-dictatorship Index (NDI) introduced in Bednay, Moskalenko and Tasnádi (2019). We show that if m denotes number alternatives, then as voters tends to infinity NDI any anonymous voting rule ( − 1)/ , which equals constant rule.
