The Condorcet paradox revisited

چکیده

We analyze the simplest Condorcet cycle with three players and three alternatives within a strategic bargaining model with recognition probabilities and costless delay. Mixed consistent subgame perfect equilibria exist whenever the geometric mean of the agents’ risk coefficients, ratios of utility differences between alternatives, is at most one. Equilibria are generically unique, Pareto efficient, and ensure agreement within finite expected time. Agents propose best or second-best alternatives. Agents accept best alternatives, may reject second-best alternatives with positive probability, and reject otherwise. For symmetric recognition probabilities and risk coefficients below one, agreement is immediate and each agent proposes his best alternative.

Bertrand’s Paradox Revisited: More Lessons about that Ambiguous Word, Random

The Bertrand paradox question is: “Consider a unit-radius circle for which the length of a side of an inscribed equilateral triangle equals 3 . Determine the probability that the length of a ‘random’ chord of a unit-radius circle has length greater than 3 .” Bertrand derived three different ‘correct’ answers, the correctness depending on interpretation of the word, random. Here we employ geomet...

Avoiding the "Condorcet paradox" in stakeholder networks for participatory decision-making: an agent-based approach

We address the problem of a participatory decision-making process where a shared priority list of alternatives has to be obtained while avoiding inconsistent decisions, related to the “Condorcet paradox”. An agent-based model (ABM) is proposed to mimic this process in different social networks of stakeholders who interact according to an opinion dynamics model. Simulations’ results show the eff...

Connections and Implications of the Ostrogorski Paradox for Spatial Voting Models

The basic theme of this paper is to connect spatial voting concepts to the troubling Ostrogorski and Anscombe paradoxes (where a majority of the voters can be on the losing side over a majority of the issues). By doing so, answers to longstanding concerns are obtained; e.g., Kelly conjectured that an Ostrogorski paradox ensures that no candidate can be a Condorcet winner; we prove this is true ...

Explaining All Three-Alternative Voting Outcomes

A theory is developed to explain all possible three-alternative (single-profile) pairwise and positional voting outcomes. This includes all preference aggregation paradoxes, cycles, conflict between the Borda and Condorcet winners, differences among positional outcomes (e.g., the plurality and antiplurality methods), and differences among procedures using these outcomes (e.g., runoffs, Kemeny's...

Condorcet cycles? A model of intertemporal voting

An intertemporal voting model is examined where, at each date, there is a pairwise majority vote between the existing chosen state and some other state, chosen randomly. Intertemporal voting simpli…es the strategic issues and the agenda setting is as unrestricted as possible. The possibility of cycles is examined, both in the intertemporal extension to the Condorcet paradox and in more general ...
