This article presents the results of new research on the history of financial economics by analyzing the dissemination of Louis Bachelier's work.Louis Bachelier is doubtless the best known French mathematician in the history of modern finance theory. While recent studies have given us a fairly...

This paper deals with the disciplinary dimension of a very new field called econophysics and shows that despite the fact that econophysics is regularly described as an interdisciplinary approach, it is in fact a multidisciplinary field. Beyond this observation, we note that recent developments...

Financial economics and mathematical finance are the two traditional scientific disciplines that constitute modern financial theory. Although they still largely dominate modern financial theory, in the past few years a new “player” has increasingly been making itself felt and could lead to a...

This article takes place in the revision of the history of financial economics. The major argument is that the history of financial economics nowadays known was built to defend theoretical viewpoints, and therefore, to convince the scientific community to adopt these theories. More precisely,...

We analyse the work of a neglected French economist, Jules Regnault, whose Calcul des Chances et Philosophie de la Bourse (1863) laid the basis of modern stochastic models of price behaviour and contains an anticipation of econometrics. At a time when short-term speculation was denounced as...

Following recent judgement of the Supreme Court of US (June 2014), several commentators had declared that “Securities class actions are here to stay” (insidecounsel.com – September 2014, 11). This paper provides a critical perspective on this judgement, which “implicates substantive...

To date, the history of financial economics has not discussed in detail the international diffusion of financial economics (henceforth modern finance). Modern finance was supposedly “introduced” in France in the 1970s. According to some historians of financial economics, it is an American...

This article highlights the current misunderstanding between economists and econophysicists by adopting the financial economists' viewpoint in order to explain why the works developed by econophysicists are not recognized in finance. Because both communities do not share the same scientific...

This paper aims at analyzing the unexpected influence of Financial economics on Physics. The rise of Econophysics, a fundamentally new approach in finance, suggests that the influence between the two disciplines becomes less unilateral than in the past. Methodological debates emerging in...
