Economics and Complexity Lunch seminar

The Economics and Complexity Lunch Seminar takes place every two weeks on Thursday from 12:30 to 13:30 at University Paris 1 (Room S/3, Maison des Sciences Économiques, 106 - 112 Boulevard de l'Hôpital). It aims at providing a friendly and informal atmosphere in which ongoing research can be presented and discussed. The seminar welcomes both theoretical and empirical works applying concepts and methods broadly related to the growing field of economics and complexity, including networks and agent-based models. Please feel free to contact me, Alessandro De Sanctis or Kerstin Hotte if you want to make a presentation.

Colloque arts et mathématiques, Paris, December 2017

Together with Yann Toma from Art&Flux, we are organizing a one-day conference that brings together artists, mathematicians and social scientists in order to investigate how art can contribute to a better understanding of mathematics, how mathematics can be used by artists and how arts and mathematics together can help us better understand social dynamics. See the great website designed by Mathieu Legrand-Losfeld for the workshop.

Workshop on Production Networks, Paris, 16 June 2017

The aim of the workshop was to present recent advances on economic models of production networks. Invited presentations focused in particular on the formation of

production networks, the propagation of shocks on these networks, network-based multipliers and real-financial linkages. A detailed program is available here.

Rencontres arts et mathématiques, Paris, July 2017

Together with Yann Toma from Art&Flux, we are running a two year project on the synergies between art & modeling/mathematics in thinking about social dynamics.The program of our last workshop is available here.

Statistical Physics of Financial and Economic Networks, Paris, 15-16 July 2016

With Guido Caldarelli, Stefano Battiston and Tiziano Squartini, we are organizing a satellite workshop to StatPhys26 on financial and economic networks. We are now accepting contributions for this workshop. Please send contribution proposals in the form of (up to) 1.5 page abstract (including figures) to financialeconomicnetworks at gmail.com. You can find more information about the workshop here.

Bielefeld-Paris Agent-Based Modeling Workshop Paris, January 2016

With Herbert Dawid, we are organizing a workshop on agent-based modeling at University paris 1 on January the 8th 2016. The program is available here.

Social Dynamcis and Climate Change, Paris, October 2015

The aim of the conference « social dynamics and climate change » is to offer the scientific community and stakeholders involved in the climate policy debate an overview of the social changes that are and could be triggered by climate change mitigation and adaptation and to present methods and tools developed to represent, understand, influence or govern those changes. The conference is organized in echo to the COP 21 negotiations that will take place in Paris in December 2015, but offers a complementary perspective on the global challenge posed by climate change. Indeed, independently of the outcome of the international negotiations, the key challenge for our societies will remain: climate change mitigation and adaptation implies that societies will have to coordinate themselves at multiple scales on new systems of values, new forms of institutional, spatial and economic organization. More information about the conference here.

Mageco 2015, Paris, Novembre 2015

Avec Annick Vignes, nous organisons les 4ème journée MAGECO- Modèles basés agents en Economie, le vendredi 27 Novembre 2015 à l'EHESS. Le programme est disponible ici

Uncertainty, Digital Sciences and the Long Term, Florence September 2013

This is a workshop we organize together with Diana Mangalagiu and David Tuckett at the villa finaly in Florence from the 15th to the 17th of September 2013. The aim of the workshop is to reflect on the contrast between the sense of control brought forward by the surge of big data and our massive uncertainty (and perhaps anxiety) about the long-term.

Big Data but No Future ?

Second Open Global System Science Conference, Brussels June 2013

This is the second Global System Science annual conference, organized by the Global Climate Forum on behalf of the GSDP project. The purpose of the conference is to discuss a possible research program for Global Systems Science and to further build up the community of practitioners from science, policy and civic society working on the pressing global challenges of our times.

Together with Stefano battiston we have conveyed three small workshops on sustainable finance while Diana Mangalagiu and David Tuckett have ran the prequel of the September Florence workshop. There is much more in the conference program, which is available on the Global System Science Blog together with the orientation paper on global system science that GSDP as produced for the European Commission.

First Open Global System Science Conference, Brussels November 2012

This conference is organized by the steering committee of the EU project Global Systems Dynamics and Policy of which I am proud to be a member. The aim of the Conference is to contribute to the development of Global Systems Science (GSS). The study of problems as diverse as global climate change and global financial crises is currently converging towards a new kind of research – Global Systems Science. GSS builds on economics as well as on climatology, on history as well as on geography and on a variety of further disciplines. However, it is no attempt to renew the failed pursuit for a single unified science. It simply integrates insights and methods that are useful in studying global systems and develops them further for that purpose.

17th WEHIA Annual Conference, Paris June 2012

This year the anual conference of the Society for Economic Science with Heterogeneous Interacting Agents is organized in Paris at the Pantheon by University Paris II and I. I am in the organizing committee together with Annick Vignes, Gerard Ballot and Sylvain Mignot. More information on the conference website.

Global Systems as Networks of Networks, Florence May 2012

Together with Guido Caldarelli and Jürgen Kurths, we are organizing a workhop on global systems as networks of networks at the villa finaly in Florence.

Analyzing the influence of networks on the behavior of agents and organizations has vastly improved, over the past decade, our understanding of the social dynamics at the source of a variety of phenomena such as the build-up of systemic risk in financial markets, the innovativeness of regions, the development of international trade, the formation of eco-industrial clusters or the spreading of information/influence/influenza. Accordingly networks have became paradigmatic examples of transdisciplinary concepts, laying at the core of research programs in economics, finance or environmental science.

The aim of this workshop is to build upon this common interest in order to identify questions and challenges raising at the interface of these disciplines and to approach them as problems posed by networks of networks. As networks have proved instrumental in the analysis of sub-systems such as the interbank market for loans or the life-cycle of products, networks of networks might be useful to approach socio-environmental issues from a global perspective, focusing on the meta-interactions which are at play between international trade, economic growth in China and climate change mitigation or between green growth and the recovery from the financial crisis.

A detailed program is available here.

GSDP Agent-based Modeling Workshop in Paris, Paris September 2011

Together with Herbert Dawid, Herbert Gintis, Armin Haas and Imre Kondor, we organize at the Sorbonne in Paris a workshop on agent-based modeling in economics.

A number of ongoing projects in agent-based computational economics start delivering promising results: from networks of interacting agents emerge dynamics reproducing a growing number of stylized facts of economic systems. The usage of computer simulations has indeed allowed to explore economic dynamics beyond the

frontier of analytical tractability where general equilibrium theory had been left without proper dynamical foundations.

Agent-based models exhibit a variety of structures, interactions, behavioral assumptions and use different software platforms and/or programming languages. Though it underlines a large range of potential applications for agent-based models, this variety also suggests a possible lack of common structures in the field which could hamper the communication, the comparison and the evaluation of such models. In order to prevent these failures and to foster the development of future research, it is thought useful to gather leading actors in the field so as to define a set of structuring guidelines. Therefore, the workshop will bring together economists and complex scientists with an expertise in agent-based modeling with the aim of developing standards for the description, the specification and the validation of agent-based models and to identify promising avenues for formal analysis of such models.
