Thibault Schrepel has been a leading voice in advocating for the integration of AI and data-driven approaches in antitrust enforcement, coining the term Computational Antitrust. His research suggests that AI and machine learning can play a crucial role in enhancing the capabilities of antitrust agencies by automating complex analyses, detecting patterns of anti-competitive behavior, and increasing the efficiency of enforcement.

Here are some key points from Schrepel's work:

1. Automating Antitrust Procedures: Schrepel argues that the complexity of digital markets, especially with the rise of platforms and ecosystems like Google, Amazon, and others, demands more sophisticated tools. AI can help process large volumes of data to uncover potential anti-competitive practices such as price-fixing algorithms or collusive behaviors, which are often hidden in large datasets. His Computational Antitrust project aims to leverage AI to aid antitrust agencies in this effort, bringing together over 65 antitrust authorities to explore its potential.
2. AI for Market Analysis: AI can enhance the way markets are analyzed by predicting the future behavior of companies and the competitive effects of mergers or acquisitions. This can give regulators better foresight in assessing whether certain corporate actions might lead to monopolistic dominance, something traditional methods struggle with.
3. Bias and Complexity Considerations: Schrepel also acknowledges the limitations and risks of using AI in antitrust. He warns of the potential biases in algorithms, which may reflect the biases present in the training data. These biases could result in AI-driven decisions that unfairly target certain companies or behaviors. Moreover, Schrepel advocates for combining complexity science with antitrust enforcement to better understand the non-linear dynamics of digital ecosystems and how AI can be used responsibly.
4. Collusion and AI: Another critical aspect of Schrepel's work focuses on algorithmic collusion, where companies may not need to communicate explicitly to fix prices but instead rely on AI-driven algorithms to adjust their prices based on competitors' actions. This is an emerging area where traditional antitrust frameworks struggle, and Schrepel's research suggests that computational antitrust can help detect these subtle forms of collusion by analyzing vast amounts of market data in real-time.

In summary, Thibault Schrepel's research highlights the promise and challenges of using AI in antitrust enforcement. By automating complex analyses and understanding the intricate dynamics of digital markets, AI could significantly improve how antitrust authorities operate. However, ensuring the fairness and transparency of these AI systems remains a critical challenge for policymakers.
