THE OBJECT OF BRIBERY

Swap Bribery

In voting theory, bribery is a form of manipulative behavior in which an external actor (the briber) offers to pay the voters to change their votes in order to get her preferred candidate elected. We investigate a model of bribery where the price of each vote depends on the amount of change that the voter is asked to implement. Specifically, in our model the briber can change a voter’s preferen...

Estimating the Effects of Foreign Bribery Legislation

Foreign bribery the payment of bribes across borders poses a classic collective action problem in theory. A firm may extract benefits through the payment of bribes to foreign public officials without its own country bearing the associated costs of governmental corruption, and hence while eliminating foreign bribery may be in the best interests of all who are engaged with the global economy, the...

Nonuniform bribery

We study the concept of bribery in the situation where voters are willing to change their votes as we ask them, but where their prices depend on the nature of the change we request. Our model is an extension of the one of Faliszewski et al. [FHH06], where each voter has a single price for any change we may ask for. We show polynomial-time algorithms for our version of bribery for a broad range ...

The Complexity of Bribery in Elections

We study the complexity of influencing elections through bribery: How computationally complex is it for an external actor to determine whether by a certain amount of bribing voters a specified candidate can be made the election’s winner? We study this problem for election systems as varied as scoring protocols and Dodgson voting, and in a variety of settings regarding homogeneous-vs.-nonhomogen...
