Agent Based Models

Model

Agent-based models (ABMs) simulate complex financial systems by modeling individual participants and their interactions rather than relying on aggregate market assumptions. In quantitative finance, these models move beyond traditional equilibrium frameworks to capture emergent phenomena like market bubbles, crashes, and liquidity cascades. By defining agents with specific trading strategies, risk tolerances, and information processing capabilities, ABMs provide a dynamic environment for stress testing derivatives portfolios. This methodology offers a more realistic representation of market microstructure and non-linear dynamics than conventional econometric models.
