Professional meeting
Goddard took the attendees through the modeling paradigm of the 4see model. He informed members that it differs from other macroeconomic modeling methods. It expresses constraints between components of the macro economy as equations which describe how they affect each other, and then uses iterative time-stepped simulation to evolve the model of the system forward in time. A key principle in 4see modeling is handling of distinctly different classes of flows. The full 4see- GB model of the UK
