Information geometries and Microeconomic Theories

More than thirty years ago, Charnes, Cooper and Schinnar (1976) established an enlightening contact between economic production functions (epfs) — a cornerstone of neoclassical economics — and information theory, showing how a generalization of the Cobb-Douglas production function encodes homogeneous functions. As expected by Charnes et al., the contact turns out to be much broader: we show how information geometry as pioneered by Amari
