BAM Engine 0.5.1 and the Launch of bamengine.org

We are excited to announce BAM Engine 0.5.1 and the launch of bamengine.org.

What is BAM Engine?#

BAM Engine is a Python framework implementing the BAM (Bottom-Up Adaptive Macroeconomics) agent-based model from Macroeconomics from the Bottom-up (Delli Gatti et al., 2011). The model simulates households, firms, and banks interacting across labor, credit, and goods markets.

What’s New in 0.5.1#

Extension Bundles#

The new Extension dataclass and sim.use() API let you activate model extensions with a single call:

from extensions.rnd import RND
sim.use(RND)

Pre-built bundles: R&D/Growth+, buffer-stock consumption, and taxation.

Documentation#

The User Guide now covers custom roles, events, relationships, pipelines, operations, extensions, validation, calibration, and best practices.
