Advancing Economic Simulations with ADAGE: A Novel Framework Combining Agent-Based Modeling and Reinforcement Learning

Sunday 09 March 2025


The quest for a more realistic economic simulation has long been a challenge for researchers in the field of artificial intelligence and economics. A new paper published recently makes significant strides towards achieving this goal by introducing a novel framework that combines agent-based modeling, reinforcement learning, and bilevel optimization.


The problem with traditional economic simulations is that they often rely on oversimplified assumptions about human behavior, such as rational expectations or perfect knowledge. In reality, humans make decisions based on incomplete information, biases, and emotions. To create more realistic simulations, researchers need to incorporate these complexities into their models.


The new framework, called ADAGE (ADaptive AGEnt-based modeling), addresses this challenge by using a two-layer approach. The first layer consists of agent-based modeling, which simulates the behavior of individual agents, such as consumers and producers, in an economic system. Each agent is equipped with its own decision-making mechanism, which takes into account its own goals, constraints, and preferences.


The second layer uses reinforcement learning to optimize the parameters of the agent-based model. This allows the model to learn from experience and adapt to changing market conditions. The optimization process is done using a bilevel optimization technique, which ensures that the optimal solution is found by balancing the conflicting objectives of individual agents.


To test the effectiveness of ADAGE, researchers created a simulation of a stock market with 1,000 agents. They then compared the results with those from traditional economic models and found that ADAGE produced more realistic outcomes, such as price volatility and bubbles.


One of the key advantages of ADAGE is its ability to capture the complexity of human decision-making. By incorporating biases, emotions, and incomplete information into the model, researchers can simulate real-world market behavior more accurately. This has significant implications for policymakers and investors who need to make informed decisions in complex economic systems.


The potential applications of ADAGE are vast. It could be used to simulate the impact of different policies on an economy, predict stock market trends, or even design more efficient financial markets. The framework’s ability to learn from experience also makes it a promising tool for real-world decision-making.


While there is still much work to be done in refining and testing ADAGE, this breakthrough has significant potential to revolutionize the field of economics and artificial intelligence. By creating more realistic simulations, researchers can better understand the complexities of human behavior and make more informed decisions in an increasingly complex world.
