John von Neumann between Physics and Economics: A Methodological Note

Luca Lambertini ()

Working Paper series from Rimini Centre for Economic Analysis

Abstract: A methodological discussion is proposed, aiming at illustrating an analogy between game theory in particular (and mathematical economics in general) and quantum mechanics. This analogy relies on the equivalence of the two fundamental operators employed in the two fields, namely, the expected value in economics and the density matrix in quantum physics. I conjecture that this coincidence can be traced back to the contributions of von Neumann in both disciplines.
