Algorithms: How they can reduce competition and harm consumers
Paper from the CMA's Data, Technology and Analytics (DaTA) Unit, identifying potential harms to competition and consumers from the use of algorithms.
Documents
Details
The paper identifies potential harms to competition and consumers from the use of algorithms, focusing on those the Competition and Markets Authority (CMA) or other national competition or consumer authorities may be best placed to address.

These include direct harms to consumers, such as personalisation of prices and other aspects of online choice architecture. They also include harms to competition, such as the use of algorithms to exclude competitors (for example, to facilitate self-preferencing) and the potential for algorithms to facilitate collusion.
The paper also summarises techniques that could be used to analyse algorithmic systems and the role of regulators in addressing these harms.
Call for information: closes 16 March 2021
We are now seeking views and evidence on the harms outlined in the paper to inform our Analysing Algorithms Program. We are also interested in information about specific issues with firms that we could examine and consider for future action. Stakeholders are invited to respond by 16 March 2021.

Background
The Competition and Markets Authority鈥檚 Data, Technology and Analytics (DaTA) unit is helping it stay ahead, using the latest in data engineering, machine learning and artificial intelligence techniques.鈥疶he DaTA unit is a multidisciplinary team of 35 people that brings together data scientists, data engineers, technologists and behavioural scientists.
