The AI Economist: Improving Equality and Productivity with AI-Driven Tax Policies

Our work fits within a larger context of recent advances in RL. RL has been used to train AIs to win competitive games, such as Go, Dota, and Starcraft. In those settings, the RL objective is inherently adversarial ("beat-the-other-team"). Machine learning has also been used for the design of auction rules. In this work, we instead focus on the opportunity to use AI to promote social welfare through the design of optimal tax policies in dynamic economies. Many studies have shown that high income inequality can negatively impact economic growth and economic opportunity.
