Purpose This study aims to investigate whether United Kingdom (UK)-based companies have changed their voluntary disclosures on curbing the bribery of foreign officials in response UK Bribery Act 2010, and if so how such disclosure changes substantively reflected allegations by news media. Design/methodology/approach By using notions institutional pressure decoupling applying content thematic an...

We study the problem of bribery in multiwinner elections, for the case where the voters cast approval ballots (i.e., sets of candidates they approve) and the bribery actions are limited to: adding an approval to a vote, deleting an approval from a vote, or moving an approval within a vote from one candidate to the other. We consider a number of approval-based multiwinner rules (AV, SAV, GAV, RA...

Control and bribery are settings in which an external agent seeks to influence the outcome of an election. Faliszewski et al. [7] proved that Llull voting (which is here denoted by Copeland) and a variant (here denoted by Copeland) of Copeland voting are computationally resistant to many, yet not all, types of constructive control and that they also provide broad resistance to bribery. We study...

We consider a model of bribery in an asymmetric procurement auction. In return for a bribe from the dishonest supplier, the auctioneer has the discretion to allow this supplier to revise his bid downward to match the low bid of the honest supplier. The dishonest supplier can also win the contract outright without paying a bribe by bidding below the honest supplier. We investigate the effect of ...

This paper investigates the design of optimal procurement mechanisms in the presence of corruption. After the sponsor and the contractor sign the contract, the latter may bribe the inspector to misrepresent quality. Thus, the mechanism affects whether bribery occurs. I show how to include bribery as an additional constraint in the optimal-control problem that the sponsor solves, and characteriz...

The classic bribery problem is to find a minimal subset of voters who need to change their vote to make some preferred candidate win. We find an approximate solution for this problem for a broad family of scoring rules (which includes Borda and t-approval), in the following sense: if there is a strategy which requires bribing k voters, we efficiently find a strategy which requires bribing at mo...
