Law and Economics: From Theory to Practice and Back AgainParis
Speakers: William Davies (University of London) (to be confirmed), Thierry Kirat (University Paris-Dauphine), Frédéric Marty (University of Nice), Dina Waked (Sciences Po Paris)
What are the origins, developments and relevance of “law and economics”? What role does it play today within the field of economics? The aim of the conference is to put the discipline – established in the 1920s around the ideas of John Commons – into historical perspective.
How did the field develop from an institutional analysis of law to an economic analysis? Special focus will be placed on the convergence of the rules of public policy towards private standards.
· The search for law and economics: theoretical origins
· From institutional law and economics to the economic analysis of law: Overtaking competition law
· The convergence of public policy towards private standards, according to the second wave of law and economics
Conference in honour of Nicole El KarouiSorbonne University - Paris
Co-organization of the conference held in honour of Nicole El Karoui – a pioneer of mathematics applied to finance – for her 50 years of scientific contributions. The four-day conference began with a day dedicated to Women in Science (WiSE), co-sponsored by the Cournot Centre and Foundation. The event marked the launch of the Cournot programme – geared towards a young audience – to promote the role of women in the development of probability theory and the advancement of their contributions.
Math en Jeans National ConferenceSaclay
As part of its Initiation to Probability program for middle-school students from Priority Education networks (REP) in France, the Cournot Foundation sponsored students from the Collège des Petits Ponts in Clamart, near Paris, to attend the annual national conference of the association Math en Jeans at CentraleSupélec Higher Education and Research Institution in Saclay. The students had a stand, presenting the methods and results of their work on the game of maximum.

How to Model the Roughness of Oil and Gas Dynamics

A Time-Frequency Analysis of Oil Price Data
Presentation_Josselin Garnier - Knut Solna_031017.pdf

What can we say about the evolution of oil and gas prices?
The conference will address this issue by:
(i) presenting tools that can be used to describe the complex multi-scale structures of energy-market price data;
(ii) discussing the possible mechanisms behind these regime shifts;
(iii) considering the possible implications for hedging and risk assessment.
A special focus will be put on the evolution of prices since the end of 2014.
The observation of market price fluctuations sometimes reveals behaviors that cannot be well captured by standard models based on discrete-time random walks or continuous diffusion. In standard models, the return fluctuations of a risky asset are driven by Brownian motion, giving independent Gaussian returns. It has become clear that oil and gas price data vary at different interconnected scales, slow or fast: they have a complicated multi-scale structure that, moreover, may vary over time. Time-frequency analysis can be used to identify the main features of these variations and, in particular, the regime shifts. The analysis derives from a wavelet-based decomposition, a special decomposition of a signal in time-frequency components, and the associated scale spectrum. The joint estimation of the local Hurst coefficient (an index of smoothness) and volatility is the key to detecting and identifying regime shifts and changes in the oil price. For the first time since 1986, "persistence" processes of unprecedented force occurred between the end of 2014 and 2016, opening up a new period.

The work of Kiyosi Itô and the Japanese school of stochastic processes that he founded is exceptional both in its beauty as pure mathematics and in the insights it has provided in biology, chemistry, quantum physics, electrical engineering, and finance. As the International Mathematical Union attested in awarding Itô its first Carl Friedrich Gauss prize in 2006, his work ranks as part of the world’s cultural heritage.
From its outset, however, Itô’s work has stood in a special relationship to French mathematicians. The first citation in Itô’s published work, in fact, the first sentence of his first article, was to Paul Lévy’s, Théorie de l’addition des variables aléatoires . As Itô later wrote, he learned stochastic processes from this book. His goal was to make fully mathematical the beautiful structure the book depicted, and he succeeded. It is often said that other French mathematicians understood Lévy only after Itô had explained his contribution. Thirty years later, in the 1970s, Itô was still interacting with French mathematicians, embracing and further developing Paul-André Meyer’s semimartingale-based version of Itô’s theory of stochastic integration. Today, French mathematicians remain among those most keen to develop the applications of Itô’s calculus in physics and finance.
This conference examines Itô’s legacy from the perspective of this relationship. Is the theory of stochastic processes now truly a theory of sample paths as Lévy had envisioned? What has made Lévy processes and Itô’s understanding of stochastic integration so fruitful for applications in physics and finance? Where is Itô’s legacy taking us today?
