Collusion Theory: Where to Go Next?

چکیده
This note comments on Feuerstein’s (Feuerstein, Switgard, BCollusion in industrial economics: A survey,^ forthcoming in Journal of Industry, Competition and Trade, 2005) survey of collusion theory. I start by presenting evidence from a recent real-world collusion case: the lysine industry. Based on this, I point out a few areas where collusion theory can improve: (a) the problem of equilibrium choice (bargaining over each firm’s share), which is especially important in asymmetric oligopolies; (b) the problem of equilibrium implementation, including in particular communication in an asymmetric information context; and (c) the relation between price wars and collusion. I conclude with a few notes on policy issues, namely leniency programs and cartel detection

How to Eliminate Collusion in Tenders and Auctions, using Game Theory (Determination of Ceiling and Floor Prices)
Governments and firms in accordance to their duties, obliged to inevitably contracts with Individuals and legal entities, especially in auction and tender process. Since, the law of conducting tenders and auctions is lacking efficiency and has major objection, therefore, this has led to the dissemination and development of areas of corruption in these contracts (through collusion). In this pape...
متن کاملA collusion attack on the fuzzy vault scheme
The Fuzzy Vault scheme is an encryption scheme, which can tolerate errors in the keys. This leads to the possibility of enhancing the security in environments where these errors can be common, such as biometrics storage systems. Although several researchers have provided implementations, we find that the scheme is vulnerable to attacks when not properly used. This paper describes an attack on t...
متن کاملAn experiment on a core controversy
A longstanding criticism of the core is that it is too sensitive to small changes in player numbers, as in a well known example where one extra seller (resp. buyer) causes the entire surplus to go to the buyer’s (seller’s) side. We test this example in the lab, using several different trading institutions. We find that successful collusion is relatively infrequent and decreasing over time even ...

This paper describes how an offline software tool identifies collusion on assessed video clips. The collusion detection processing is independent of the length, format, frame rate, compression and content of the video clips. The process consists of extracting prominent features from individual frames for each student’s video clip and passing these through a rigorous comparison process. Collusio...
متن کاملOptimal collusion-proof auctions
We study an optimal collusion-proof auction in an environment where subsets of bidders may collude not just on their bids but also on their participation. Despite their ability to collude on participation, informational asymmetry facing the potential colluders can be exploited significantly to weaken their collusive power. The second-best auction — i.e., the optimal auction in a collusion-free ...
