Milton Friedman, The Methodology of Positive Economics (1966)

Backgrounds

  • Friedman's controversial methodology work
  • two potential motivations for this: Mont Pelerin (1947-) affection and refusal to Harry Markowitz (1955)
  • might be a reaction from economics to financial frameworks

Richard Roll, A critique of the asset pricing theory's tests Part I: On past and potential testability of the theory (1977)

Backgrounds

  • Roll's critique against CAPM
  • Quantum Field Theory per se is not refutable for its infinite dimensional nature. CAPM is also infinite dimensional and not refutable
  • Fischer Black once said: "The easiest theory to falsify is a theory which is false."

Backgrounds

  • Jan Tinbergen was a Dutch economist
  • His gravity model is standard for international/geographical economics
  • GDP works as "mass" factor in economic gravity model 
  • He also gave a foundation for Robert Mundell's policy mix theory
  • Squartini and Garlaschelli (authors) try to justify and analyze Tinbergen's view based on quantum entropy of international trade

Jan W. Dash, Path Integrals and Options I (1988)

Backgrounds

  • The author, as of writing, was a quantitative financier in Merrill Lynch
  • formerly he was a physicist in Marseille, France
  • (probably) first proposal to apply path integral for asset pricing models
  • path integral does not assume complete probability per se
  • so it might give an open (indefinite) model of asset pricing
