Decoy ballots do not count in election outcomes, but otherwise they are indistinguishable from real ballots. By means of a game-theoretical model, we show that decoy ballots may not provide effective protection against a malevolent adversary trying to buy real ballots. If the citizenry is...

Voting systems based on decoy ballots aim at preventing real ballots from being bought. Decoy ballots do not count in election outcomes, but are indistinguishable from real ballots. We introduce a “Devil's Menu” consisting of several price offers and allocation rules, which can be used by a...

We present a model of elections in which interest group donations allow candidates to shift policy positions. We show that if donations were prohibited, then a unique equilibrium regarding the position choices of candidates would exist. With unrestricted financing of political campaigns two...

We consider a collective choice process where three players make proposals sequentially on how to divide a given quantity of resources. Afterwards, one of the proposals is chosen by majority decision. If no proposal obtains a majority, a proposal is drawn by lot. We establish the existence of...

We present a model of elections in which interest group donations allow candidates to shift policy positions. We show that if donations were prohibited, then a unique equilibrium regarding the platform choices of candidates would exist. Our game with financing of political campaigns exhibits two...

We consider an infinite-horizon model of elections where policy changes are costly for citizens and parties. The so-called costs of change increase with the extent of the policy shift and make policy history-dependent. First, we provide a detailed description of the equilibrium dynamics and...

We introduce a two-stage, multiple-round voting procedure where the thresholds needed for approval require a qualified majority and vary with the proposal on the table. We apply such a procedure to instances of public-good provision where the citizens’ valuations can take two values and are...

We consider non-cooperative bargaining on the division of a surplus under simple majority rule. We use the "open rule" bargaining protocol as originally suggested by Baron and Ferejohn (1989): Proposals can be amended before they are voted on. It is widely known that there are significant gaps...
