ABSTRACT
On Tuesday April 5, 1933 at 17.45-and one may presume it was precisely at that time-Ragnar Frisch delivered a paper at the Institut Henri Poincaré in Paris. Its title was “Conclusion: La signification des lois sociales et méchaniques. Invariance et rigidité. Remarques sur une philosophic du chaos.” It was the final paper of a series of eight, dealing with mathematical economics and advanced topics of the newly born branch of econometrics.
