Detecting multiple seller collusive shill bidding

作者：

Highlights：

• This is the first paper to examine the scenario of multiple colluding sellers engaging in shill bidding.

• We outline the optimal strategy to engage in to mask shill bidding behaviour.

• We propose the first algorithm to provide evidence of whether groups of sellers are colluding.

• Performance is demonstrated using simulated and commercial auction data.
