Winner-take-all dynamics are prevalent throughout the human and natural worlds. Such dynamics promote competition between agents as they secure available resources for themselves and undermine their opponents. However, this competition is mitigated by the capacity of any single agent to amass resources on its own. Thus, agents collude with one another to ensure that one of their own can win and...

This paper analyzes “In‡uence Peddling”with interaction between human capital transfer and collusion-building aspects in a model, in which each government o¢ cial regulates multiple …rms simultaneously. We show that (i) there exists an “optimal” division rule for collusion between a sequence of “quali…ed”regulators and a …rm; (ii) as the regulators increasingly bene…t from the collusion, they s...

Crowdsourcing is a popular method for crowd workers to collaborate on tasks. However, coordinate and share answers during the crowdsourcing process. The term this "collusion". Copies from others repeated submissions are detrimental quality of assignments. majority existing research collusion detection limited ground truth problems (e.g., labeling tasks) requires predetermined threshold be estab...

The widespread use of market-making algorithms in electronic over-the-counter markets may give rise to unexpected effects resulting from the autonomous learning dynamics these algorithms. In particular possibility “tacit collusion” among market makers has increasingly received regulatory scrutiny. We model interaction a dealer as stochastic differential game intensity control with partial infor...

We examine a simple model of collusion under a single-object secondprice auction. Under the appropriate parameter conditions, in particular as long as collusion is neither too easy, nor too difficult, we find that the optimal policy involves both an effective ceiling, as well as a reserve price set at the lowest bidder valuation.

Collusion is covert co-operation between participants of a game. It poses technical, game design, and communal problems to multiplayer games that do not allow the players to share knowledge or resources with other players. In this paper, we analyse experimental data from a simple twodimensional game using synthetic players to elicit features that indicate collusion.

We provide new, concise characterizations of the Banzhaf value on a …xed player set employing just the standard dummy player property and one of the collusion properties suggested by Haller (1994) and Malawski (2002). Within these characterizations, any of the collusion properties can be replaced by additivity and the quarrel property due to the latter author. Journal of Economic Literature Cla...

In this paper, we simulated Collusion and Network partition DoS attacks using GlomoSIm (GLobal MObile information system SIMulator). The network with 36 nodes in grid pattern was chosen. Throughput analysis with and without DoS attack was carried out for varying number of nodes. The importance of fairness in MAC layer is also justified through the results obtained. Keywords— DoS, Collusion, Par...

Detection and deterrence of collusion are longstanding antitrust problems, made difficult because collusive arrangements are usually surreptitious. In this paper, I discuss factors that facilitate or inhibit collusive schemes, as well as circumstances where detection is possible. I describe how industrial organization economists diagnose collusion (both explicit and tacit) among firms.
