Overcoming the Current Knowledge Gap of Algorithmic “Collusion” and the Role of Computational Antitrust

This is a new article published by the Stanford Computational Antitrust Project. It covers a broad range of topics.  The most interesting topics, to me, include

• A discussion of some existing repricing software.  I have not seen a comprehensive survey of all (or most) of the pricing algorithms used today.  Repricers are one type of such algorithms.  
• A survey of methodologies to detect algorithmic pricing.  The question here is that, without the factual knowledge of whether a firm is using algorithms to automate pricing, how do we find out if an algorithm is being used.  Researchers have developed certain methodologies. 
• A discussion of the use of cartel detection tools by various competition authorities. 

The paper also discusses algorithmic collusion more generally, some of the discussions overlap with other articles including my book chapters.
