Countries that elect their policy-makers by means of Plurality Voting tend to have a two-party system. We conduct laboratory experiments to study whether alternative voting procedures yield a two-party system as well. Plurality Voting is compared with Approval Voting and Dual Voting, both of which allow voters to vote for multiple candidates, but differ in whether voters are required to cast al...

Electronic voting is a prime application of cryptographic tools. Many researches are addressing election or confidence voting in this area. We address a new type of voting scheme “Divisible Voting Scheme,” in which each voter has multiple ballots where the number of ballots can be different among the voters. This type of voting is popular, however there is no secure protocol which achieves this...

The classic Gibbard-Satterthwaite Theorem establishes that only dictatorial voting rules are strategy-proof; under any other voting rule, players have an incentive to lie about their true preferences. We consider a new approach for circumventing this result: we consider randomized voting rules that only approximate a deterministic voting rule and only are approximately strategy-proof. We show t...

An unhealthy good causes health issues in the long run. It creates a misperceived utility loss and increases health care costs. Conversely, a healthy good provides misperceived utility gains and reduces health care costs. Individuals differ in income and in their degree of misperception; they vote over a fat tax according to their misperceived utility. A fraction of the tax proceeds is "earmark...

We study the parameterized control complexity of Bucklin voting and of fallback voting, a voting system that combines Bucklin voting with approval voting. Electoral control is one of many different ways for an external agent to tamper with the outcome of an election. We show that even though the representation of the votes and the winner determination is different, the parameterized complexity ...

All nations needs a democracy and nations in which democracy exists are trying for improvement in voting system. Recent Movement of Egypt and all developed nations having a democracy shows the value of voting. Developing nations like India are spending huge money to improve their whole voting system to provide a better government to their citizens. For good democracy, a voting system should be ...

Recent research on convenience voting reforms in the United States has found that programs designed to make voting easier have not succeeded in boosting turnout, and have even had the unintended consequence of exacerbating the demographic biases that already exist in the electorate by encouraging votes among those who were most likely to vote anyway but who were inconvenienced by going to the p...

We ask whether the absence of information about other voters’ preferences allows optimal voting to be interpreted as sincere. We start by classifying voting mechanisms as simple and complex according to the number of message types voters can use to elect alternatives. We show that while the elimination of information about other voters’ preferences allows optimal voting to be interpreted as sin...
