Modelling Dynamic Economic Problems on an Analog Computer
This EAI bulletin (No. ALAC 65087) by Alfred Engel and John J. Kennedy presents the theory and mechanization of dynamic economic models on analog computers, contrasting analog-friendly continuous differential-equation approaches with finite-difference sequence models. It covers non-genuine and genuine lags, open systems, forced-goal (boundary-value) problems, policy-decision mechanization using comparators and function switches, and the use of track-and-store amplifiers and VDFGs — illustrated with circuit diagrams for Samuelson's Second Interaction Model and Leontief's two-sector lag system. The EAI TR-20, PACE 231R-V, and HYDAC 2400 hybrid system are cited as representative hardware.
