AI agents in Algorithmic Electricity Markets: On the Emergence of Tacit Collusion
TL;DR
Learning-based agents in electricity markets can unintentionally lead to tacit collusion, resulting in non-competitive outcomes. This study models these dynamics using multi-agent reinforcement learning to assess the risks involved.
✦ Why It Matters
Evaluate your bidding strategies in electricity markets to mitigate risks of tacit collusion.
Key Takeaways
- Assess the risk of tacit collusion in your bidding strategies.
- Implement multi-dimensional criteria for evaluating agent behavior.
- Monitor agent interactions to prevent non-competitive outcomes.
- Consider the implications of autonomous learning in market dynamics.
How It Works
The study models electricity market bidding as a repeated game, where agents learn from past interactions. By using multi-agent reinforcement learning, agents adapt their strategies based on observed outcomes, which can lead to emergent behaviors that resemble collusion, even without direct coordination.
