    Asymmetric Information and Quantization in Financial Economics by Raymond J. Hawkins, B. Roy Frieden

    Published 2012-01-01
    “…We show how a quantum formulation of financial economics can be derived from asymmetries with respect to Fisher information. Our approach leverages statistical derivations of quantum mechanics which provide a natural basis for interpreting quantum formulations of social sciences generally and of economics in particular. …”

    Entropy and Information jump for log-concave vectors by Bizeul, Pierre

    Published 2023-02-01
    “…We show that the result holds for any pair of vectors (not necessarily identically distributed) and that a similar inequality holds for the Fisher information, thus providing a quantitative Blachmann–Stam inequality.…”
