Beyond Plurality: Truth-Bias in Binary Scoring Rules
It is well known that standard game-theoretic approaches to voting mechanisms lead to a multitude of Nash Equilibria (NE), many of which are counter-intuitive. We focus on truth-bi...

Elections with Few Candidates: Prices, Weights, and Covering Problems
We show that a number of election-related problems with prices (such as, for example, bribery) are fixed-parameter tractable (in FPT) when parameterized by the number of candidate...
