Macro Emergent is an agent-based, stock-flow-consistent model of the US economy that runs in your browser: households, firms, banks, the government and the central bank keep one shared ledger, and every payment between them is visible. Apply a shock and watch it move through the five sectors against a baseline. A separate set of forecasting models, refit nightly on the day's data releases, posts a nowcast with a 5th to 95th percentile band.
The model runs in your browser; the forecast is read from the API.
