| Outline of Final Research Achievements |
The celebrated Gibbard-Satterthwaite theorem says that if a social-choice function (or, a voting mechanism) - used to decide among a set of 3 or more alternatives - is strategy-proof and onto, then the social choice function is dictatorial (or, a single voter's top-ranked alternative is the outcome). Through my research project I have considered different scenarios where we can design some positive result, that is, non-dictatorial, strategy-proof mechanisms that also satisfy efficiency and fairness. This has applications in voting (where a group of individuals are choosing one among many candidates) and facility location problem (where a group of individuals/citizens are choosing one location among many locations to locate a public facility).
Two of my research papers have been published at Social Choice and Welfare and Games and Economic Behavior, two of the leading journals in this area. Another research project is under review at Social Choice and Welfare.
