We introduce a general problem about bribery in voting systems. In the R-Multi-Bribery problem, the goal is to bribe a set of voters at minimum cost such that a desired candidate wins the manipulated election under the voting rule R. Voters assign prices for withdrawing their vote, for swapping the positions of two consecutive candidates in their preference order, and for perturbing their appro...

Scoring systems are an extremely important class of election systems. We study the complexity of manipulation, constructive control by deleting voters (CCDV), and bribery for scoring systems. For manipulation, we show that for all scoring rules with a constant number of different coefficients, manipulation is in P. And we conjecture that there is no dichotomy theorem. On the other hand, we obta...

We show that shift bribery is intractable for the voting systems of Hare, Coombs, Baldwin, and Nanson.

In addition, it investigates the determinants of being asked for a bribe at the individual level. The results show that both personal and country characteristics determine the risk of exposure to bribery. E...

We develop a model of figurative or indirect speech, which may convey a meaning that differs from its literal meaning. The model yields analytical conditions for speech to be figurative in equilibrium and delivers a number of comparative statics results. For instance, it predicts that the likelihood of figurative speech is greater if the benefit to the listener of correctly understanding the sp...
